Outdoor Advertising Media And Innovative Gameplay

outdoor advertising media

With the advent of the digital age, the survival space of traditional media has been weakened, and TV’s status as an industry leader has been surpassed. Compared to the decline of traditional media business, the story of outdoor advertising is completely different. It is widely used in the scenes we live in, and in more diverse forms. Subtly, the way brands interact with consumers is changing.

A new audience for outdoor media
The new era has come, technologies such as the Internet of Things will give energy to outdoor advertising, the big data will drive creativity to achieve online and offline linkage, the rapid iteration of technology is dazzling, and various opportunities are fleeting. In the new era of platform development, it will be difficult for advertising media to survive alone. What advertisers need most is a platform agency that can read consumers, find the inevitable relationship between consumers and brands, and then provide effective methods, integrate various media resources, and visualize the entire delivery process.

Multi-sensory attraction
Outdoor media itself focuses on static communication. Just as TV combined with visual and auditory can occupy the dominant position of the media, if outdoor advertising can combine multiple sensory sensations such as “sight, hearing, smell, touch” to form a complementary communication, it will broaden consumers’ information reception channels, and also allow consumers to pay attention, interest, hobbies and deep memories. For example, the TEA FRAGRANCE at Luohu Subway Station.

Outdoor media content is emotional
In such an era of information flooding, quality content can attract more audiences, the platform in the field of new media is more to show content, like emotional topic type of content more attractive to the audience, a certain plot point or a sentence is easy to touch people’s hearts, on the basis of satisfying their own emotional expression, to the public’s emotional problems as the core, with emotional text to tell, the content often comes from real life, people’s emotions have a certain soothing and guiding effect.

Nowadays, the outdoor advertising market is becoming more and more standardized, and the potential market for outdoor screens has been further explored, bringing new business opportunities for the development of outdoor displays. In the face of such a huge Red Sea market, outdoor display manufacturers should seize the opportunity and occupy an important position in the outdoor market.

Advertising Advantages of Outdoor Displays

outdoor displays

Outdoor advertising, that is, advertising that uses visual or experiential media such as billboards and street signs to deliver to outdoor audiences. This kind of advertising occupies millions of screens and lightboxes around the globe in many forms.

1. Why outdoor advertising works
“Shot on iPhone” is Apple’s long-running advertising contest that recognizes the best photos taken by amateur photographers with iPhones and displayed them as outdoor advertising billboards. Apple, a world-class technology company, is a well-known loyal user of outdoor advertising for one simple reason: outdoor advertising works greatly.
Why is outdoor advertising effective? Outdoor advertising is different from digital advertising, which interferes with the online experience and people have long learned to ignore it. On the contrary, outdoor advertising has become one with the world around it and will jump into the eye for granted. Excellent outdoor advertising is very visually attractive. It can stand out from the surrounding clutter, attracting the audience’s curious attention, which is an effect that the online advertising cannot achieve. Google and Facebook are home to the world’s largest digital advertising platforms, but they use outdoor advertising extensively, and it’s easy to see why.

2. The digital advantage of outdoor advertising
Digital OOH advertising has advantages over traditional forms. Most obviously, digital displays can display unique moving images with visual appeal that static images cannot achieve. Another point is that digital displays are often controlled by a back-office computer, which opens the door to some cool ads.
Digital ads can be triggered by certain underlying conditions – time, weather, sports scores, etc. This way, brands only need to buy ad space during optimal audience contact hours. In the case of ice cream advertising, for example, a hot summer day is more attractive than a mid-winter. Digital OOH advertising can be taken to the next level. You can connect more technology to the display and its control computer to generate interactive ads that let people passing by influence what the screen displays. You can also create fun augmented reality experiences that are sure to wow viewers.
Another important advantage worth mentioning is that creating digital OOH ads is now easier than ever. Tools like ChatGPT enable users to log in to upload creatives, select target audiences, or showcase content, and launch an ad in just a few hours.

3. Programmatic outdoor advertising fuels the wave
Like online digital advertising, digital OOH advertising can be programmatically purchased. This means that ad slots can be automatically purchased based on buyer criteria, which can be specific audiences or based on environmental conditions such as the weather, competition, time of day, etc. mentioned above.

4. Use data to accurately target audiences
WITH THE HELP OF AUDIENCE MEASUREMENT PLATFORMS SUCH AS SUNTUNE, MANY OUTDOOR ADVERTISING SCREENS ARE NOW EQUIPPED WITH CAMERAS THAT CAPTURE REAL-TIME INFORMATION SUCH AS IMPRESSIONS AND REACHER AGE, DWELL TIME, GENDER TO ACCURATELY ESTIMATE AD IMPRESSIONS, LOCATION DATA, AND AUDIENCE INSIGHTS. Armed with this information, advertisers can gain insight into ad engagement and derive more accurate ad analytics.
As we move into a cookieless world, first-party data, or data collected directly by advertisers, will become increasingly important. For example, retailers often invest heavily in customer loyalty programs to uncover important insights into their customer base. This data helps the retail trade sector target specific customer segments through outdoor advertising.

5. Use outdoor advertising to capture the market behind cookies
While digital advertising solution providers such as Google have promised that online advertising will provide modern targeting capabilities, targeting and measurement difficulties remain to be solved in a short period of time. When it comes to digital OOH advertising, targeting and reporting never rely on deep understanding of individual audiences. Instead, the field evolved around identifying crowd trends, where advertisers can reach interested audiences without intrusive data such as user identities.

The use of data still needs to follow the principle of Less Is More. The basic design principles that once made outdoor advertising shine have not changed, and today they are just as important, if not more important, so that serious advertisers can excel in the field of outdoor advertising.

The Focus of Air Cooling And Thermal Design Structure

outdoor lcd kiosk

Can an air-cooled outdoor LCD cabinet reach IP6X protection level? JUDGING FROM SUNTUNE TEST EXPERIENCE, IT CANNOT BE ACHIEVED FOR THE TIME BEING, AND CAN ONLY REACH IP5X. Some tall equipment is difficult to pass the IP5X test, and the talcum powder used for the test is almost pervasive under the shaking of the confined space.

The selection of fan is mainly based on the comprehensive evaluation of the air volume, static pressure, number of fans, installation size, voltage noise, etc. required for heat dissipation, and the design of the speed control logic is directly related to the reliability and rationality of the heat dissipation of the whole machine. This requires professional thermal engineers to do a reasonable plan in the early stage of the project, to provide customers or structural design engineers. The reasonable solutions include: heat dissipation feasibility & cost, dustproof ability & maintenance period, ergonomics, machine size, door opening mode, installation mode, appearance, modularization, brightness, noise, power consumption and so on; The fan speed control logic needs to be set according to the heat, air volume and air volume corresponding to the fan duty speed.

Another focus of air-cooled heat dissipation is the calculation of heat, in which solar radiation heat according to the altitude angle and regional climate is different, solar irradiation intensity is internationally defined as direct irradiation 1120w/m², but because the LCD display is perpendicular to the ground, the front, side and back of the box sunlight is mainly oblique, the irradiation intensity will be weakened, so it can be calculated by 730-830w/m², and the irradiation intensity on the top surface of the box can be calculated according to 1000w/m². In addition, the heat of electronic components, the maximum heat is the backlight heat source of LCM, which can be calculated according to the LED light conversion rate, so as to calculate the total heat of the whole machine, and then calculate the required heat dissipation air volume.

For outdoor LCD monitor of the same size and same heat, the number of fans used on vertical LCD and horizontal LCD is not the same due to the different length of the air duct. In order to solve the problems with heat dissipation, dust, noise, power consumption, etc., the fan speed regulation should also be different, and the fan working point must not be in the stall zone, otherwise the noise would be very aloud. The definition of the P-Q curve and stall zone is different for every brand and every fan.

The market cake is not large but the competition is fierce. A few manufacturers who do not have the ability to do outdoor LCD, bought a prototype of a peer or dug a structural engineer from peers and back to copy, some even spend money to buy design drawings, only in order to enter the outdoor LCD signage industry. However, such practice of drawing scoops according to the gourd, only know that it is not known, though the structure is quite similar, the concept will eventually pay the price of heat dissipation and dust prevention, especially in projects of construction. Products without thermal design concepts will demean the quality and raise the fan costs (SUNTUNE once designed an outdoor vertical 75-inch LCD signage with only 6 axial fans. It did well in good heat dissipation and dust protection).

In the following time, SUNTUNE will continue to publish technical articles, including: the advantages and difficulties of Vapor Chamber heat dissipation, the advantages and disadvantages of air conditioning heat dissipation, the difficulties of outdoor use of high-brightness modules, the necessity of remote monitoring, LCD heat dissipation reliability test, the advantages and disadvantages of front projection sunlight reflective screen, LG-MRI product features, etc.

In the future, it is expected that all powerful manufacturers will jointly formulate standards and promote the development of outdoor LCD signage.

OOHmedia Jumped By More Than Double Digits

OOHmedia

In 2023, the advertising market will usher in a comprehensive recovery, with the support of fully liberalized policies, outdoor consumption will increase, consumer gathering, dating, travel and other demand will rise. Outdoor advertising, especially outdoor scenes with special population value, will become one of the important marketing positions for advertisers to compete for. According to the data of CTR media outdoor advertising, the advertising expenditure of elevator LCD, cinema video, high-speed rail stations, airports, and street facilities closely related to travel and entertainment has increased by double digits month-on-month.

From the perspective of key industries, the year-on-year increase in outdoor advertising spending in the FMCG and mobility industries in March 2023 was particularly obvious, with large outdoor advertising spending and active investment in industries such as beverages, food, alcoholic beverages, post telecommunications, and transportation. The spending on elevator posters and airport advertising in the food industry doubled, and the advertising growth of elevator posters was mainly driven by the significant increase in investment in many categories such as food series products, snacks and candy, and food. The food industry has also seen varying degrees of growth in elevator LCDs, cinema video and street furniture.

The transportation industry performed well in elevator scenes and train/high-speed rail stations. New energy vehicles and express delivery services are the top categories of the industry’s advertising in the elevator scene and have a large amount of advertising, and the head brands include BYD, Maverick, Autel, etc.; Airlines and cars are the main drivers of the industry’s advertising spend on high-speed rail stations, representing brands such as JetBlue, Buick, Crosstrek and others.

In terms of new brands in March 2023, more than half of the top 30 new brands for elevator posters and street furniture advertising were from the commercial service and entertainment and leisure industries, and the number of new brands in other outdoor advertising channels was less than 30. Elevator LCD is mostly a new brand in the beverage, food and pharmaceutical industries; Nearly 40% of new brands in cinema video come from the transportation and home appliance industries; The new brands of high-speed rail stations account for a relatively large proportion of household goods and transportation industries; Nearly 20% of the airport’s new brands originate from the post and telecommunications industry; New brands in the entertainment and leisure and financial industries accounted for nearly half of the seats of new subway advertising brands.

Outdoor Charging Station Advertising for New Energy Vehicles

outdoor charging station

With the torrent of the times, the outdoor media has changed from traditional static to digital out-of-home, deriving more diversified forms, which includes digital billboards and outdoor signage, as well as screen networks in places like shopping malls, healthcare venues and SPA. In addition, some new media are emerging, such as the rapid growth of new energy vehicles, and the construction of charging stations, charging piles and other infrastructure is also accelerating into the fast lane. So will the combination of charging stations and outdoor advertising become the next gold mine in the industry?

For a long time, problems such as high construction costs, long payback cycles, and low operational efficiency have plagued the development of the charging station industry. Relying solely on charging car owners for charging often does not have much profit, let alone sustained growth. Only a few companies can achieve profitability, and most operators are struggling at the loss line. How to lean the efficiency of charging stations and improve the value of charging piles has become a new topic.

Companies in the charging industry are looking for new ways out, and one promising form of profitability is beginning to emerge: combining charging piles with outdoor advertising.

The charging station, a super large flow entrance, will continue to develop in the future, and it is inevitable to produce a new profit direction, and the combination with outdoor advertising is a good choice, and many companies have begun to layout. For example, ChargeEuropa, a company focused on electric vehicle charging networks, also smelled the potential of charging pile advertising, and deployed electric vehicle charging advertising piles in Poland and Croatia. In Poland and Croatia, where the construction of charging stations is still in its infancy, ChargeEuropa provides free EV charging services for EV drivers in both countries, builds digital out-of-home media support in prime locations, and supports the operation of charging stations with advertising revenue.

Volta Industries, an electric vehicle charging Network Company already listed on the New York Stock Exchange, is engaged in a business model in which drivers can use its charging piles outside high-end malls and supermarkets for free, and its revenue depends on advertising on 55-inch electronic displays installed on charging piles. Volta has even opened free fast charging stations since then, and eligible electric car owners can get half an hour of free charging. For business districts, the location of fast-charging stations can attract high-end customers and extend reception hours, while advertiser brands can use these sites to enhance their brand influence.

SUNTUNE is also exploring the scene of charging piles for new energy vehicles, combining outdoor high-brightness LCD display and charging module to open up commercial uses such as advertising space, so that consumers can easily self-charge their cars. This charging advertising pile has gone abroad and landed in Europe.

Thermal Design And Dust Protection for Digital Outdoor Signage

digital outdoor signage

The heat of the outdoor signage mainly comes from solar radiation and the heat generated by the work of electronic components, such as high-brightness LCM, the brightness generally requires 2000-3500nits in outdoor use so to have a good visual effect, according to the light conversion rate characteristics of the LED, about 70% of the power is converted into heat. Solar radiation (Ultraviolet) and high ambient temperature are factors that directly cause the heat dissipation difficulties of outdoor digital LCD signage. Imagine that a car parked on the side of the road without shade for 2 hours at noon in the southern summer, the air temperature inside the car can reach more than 60 °C, which shows that the heat brought by solar radiation is very terrible. SUNTUNE has repeatedly measured the air-cooled heat dissipation prototype of the whole machine, and under the environmental 50 °C solar irradiation, the brightness of the large-size vertical prototype (75 inches) is 3000nits, and the maximum temperature of the LCM surface can reach nearly 70 °C.

So what are the key points of thermal design? There are probably the following points:
1. Heat calculation, system impedance and air volume calculation;
2. App environment requirements;
3. Temperature rise requirements of each component of the product;
4. Fan selection, air duct design and overall layout scheme;
5. Scheme for thermal simulation calculation;
6. The scheme is introduced into the structural design of the whole signage;
7. Prototype high and low temperature test and fan speed regulation logic correction;

Difficulties: system impedance and air volume calculation, thermal simulation calculation accuracy.

The impedance of the system is the static pressure of the whole machine, among which the main ones with greater influence are: the smoothness of the air duct, the area of the ventilation hole, and the impedance of the dust net. Among them, the selection of dust screen should consider both dustproof ability and wind resistance cannot be too high, the higher the dustproof level, the greater the wind resistance, the higher the filter cost. A lot of dust that cannot be seen with the naked eye, but after 2 years of equipment start-up, it may be found that the filter has been covered with powdery dust.

How to determine the impedance of the whole machine? The best way is to perform simulation calculations or wind tunnel tests to obtain data, but this is the difficulty of many manufacturers in the industry at present.

Perhaps some readers think that outdoor signage as long as it is not a black screen can be fine, if dust enters the equipment, just clean it regularly. Although LG and BOE have wide temperature OC, and the temperature resistance can reach 100 °C without blackening, but OC surface temperature as long as the OC surface temperature exceeds 85 °C beyond a certain period of time will appear OC yellowing, which is caused by the polarizer and cannot withstand long-term high temperature. There is also the problem of light decay of backlight LED, as long as the temperature of the LED light board exceeds 75 °C, the curve of light decay will plummet, and it is simply impossible to withstand 50,000h. In order not to black screen, some designers directly use a lot of fans, thinking that more fans will solve the problem of heat dissipation, which is also unreasonable. If the installation position of the fan is not reasonable, the formation of turbulence will also affect the heat dissipation and play a counterproductive role. And at the same time, more fans mean more costs. The noise and power consumption are also high.

The product concept of SUNTUNE design is less fans, good heat dissipation, high reliability, but better with the dust prevention. Equipment maintenance outdoors is limited, labor is very expensive, do not think that regular maintenance works after dust into the equipment. Dust affects the life of electronic components directly. Think it more, how to maintain it if it is installed in bulk? Why not design the product well at the design stage?

SUNTUNE LOOKS FORWARD TO WORKING WITH YOU.

Outdoor Signage Focuses on Heat Dissipation And Dust Protection

outdoor signage

Outdoor LCD signs focus on heat dissipation and dust protection. Dust protection is not only a thermal design but also a structural design. By the diameter and quantity of outdoor dust particles checked in data, it can be determined that the outdoor dust prevention requirements are ≤1μm, which means the filter efficiency F7 or above.

Some users may ask: How long does it take to clean or replace the filter for outdoor signage with F7 or other grades of filter? At present, a few outdoor signage manufacturers keep budgets low due to competition, making the filter itself low as well in efficiency, such as G4 grade or even lower, as a result, a lot of large particles of dust can pass. However, the life of the filter could be longer, because the dust with diameter of ≤ 5 μm are allowed into the chassis. As long as the outdoor LCD sign continues to work for more than a month, there would be a lot of dust between air duct OC and tempered glass in front of the screen. Once the display screen is turned off, the dust inside the glass will be more obvious, and there will be a lot of dust on the back of the screen. The PCB board will also accumulate with dust, and the display effect becomes poor, and the failure rate becomes high. Thus, with an effective dust-proof filter, the cost is high (under the same size, F7 is expected to be 4~5 times more than the price of G4), the dustproof is good, however. Only then is it meaningful to consider the period for filter replacement.

As a developer, Suntune’s design concept is that the size of the filter achieves maximum according to the internal space of the whole outdoor signage, so it can meet the replacement once in 2-3 years, or at least 1 year if the equipment is individually thin while the interior space limited. The main reason is that the cost is too high for outdoor maintenance. Filter replacement period is a consideration for thermal design. When the temperature between the internal and the external exceeds the critical point of the thermal design, and the air in the chassis is kept at a high temperature ( 60 °C or above), it’s time to consider changing the filters.

Some users may think that the high-brightness LCM with wide temperature OC will not get black screen. As mentioned earlier, the wide temperature OC can withstand temperature more than 100 °C before going to blacken, but the state of high brightness LCM has a limited temperature, over which it will inevitably cause the backlight decay fast, the OC yellowing, the lines, the optical diaphragm wrinkles, the electronic component life shortening and other problems. Therefore, the calculation of air volume, impedance and fans selection is directly related to the size, impedance and life of the filter.

In general, the larger the filter size, the better; the larger the dust capacity, the longer the life. However, at present, outdoor signage pursues light and beautiful appearance, which makes there not much space to place the filters, so the design should reasonably calculate the air volume, wind speed, fan P-Q curve in order to determine the filter size.

AT THE END OF THIS ARTICLE, SUNTUNE CALLS ON INDUSTRY MANUFACTURERS TO PAY ATTENTION TO TECHNOLOGY RESEARCH AND DEVELOPMENT, IMPROVE THE QUALITY, AND CREATE A THRIVING DEVELOPMENT OF OUTDOOR LCD SIGNAGE.

Why Develop Outdoor Small-pitch LED Display?

led display

For outdoor LED displays, its application is very extensive, in pedestrian streets, sidewalks, and shopping malls, we will see a lot of LED displays playing advertisements on the side, and many displays are placed in the middle of the square, people watch the distance of the display is also very close, and at this time, the small pitch is more suitable, because it takes care of the people watching the movie around it, so that they can also clearly see the content of the picture. The increasing demand for close-range viewing has prompted LED display manufacturers to study and develop outdoor small pitch. At present, outdoor small-pitch LED display has broken through P2.6, and there have been corresponding cases, and according to market research and feedback, there is a great demand in the market for P2.5 small-pitch LED display, therefore, outdoor small-pitch LED display around P2.5 is the main trend of future development.

To develop outdoor small-pitch LED displays, at least the following points should be considered.

1. Reduce costs.
At present, it is also because the cost of small pitch is relatively high, most of the small pitch is used indoors, and outdoor will choose a larger pitch, which can reduce the cost for customers. Then, to make outdoor small pitch become the mainstream, it is necessary to reduce costs, which requires LED display manufacturers to develop new technologies for the need of outdoor close-range displays, combined with outdoor characteristics, to develop an outdoor small pitch LED display suitable for outdoor but not too high price.

2. High degree of protection (dustproof and waterproof).
The outdoor environment is worse than the indoor, and there are more uncertain factors outdoors, especially weather factors, such as typhoons, storms and rainstorms, etc. At this time, it is necessary to have a stronger protection level of the small-pitch LED display; meanwhile the module and the box are anti-corrosion, anti-oxidation, fireproof, etc. The current aluminum alloy material is more suitable, and the aluminum material also has features of fast heat dissipation and high flatness, which can keep the LED display stable operation in any outdoor environment.

3. Energy saving and environmental protection.
The display screen used outdoors is required for long-term stable operation, which consumes electricity every day, and the price of small pitch is generally higher than that of large pitch, and it may be difficult to achieve a significant reduction in the price of the display screen, but if the energy-saving technology is applied to the small pitch LED display, its energy-saving effect will be greatly improved, which can save a large amount of electricity costs every year, thereby indirectly reducing the price for customers.

In addition to energy saving, environmental protection is also a more important factor, because outdoor small-pitch LED displays will be used closer to people and closer to daily lives. Whether the display box will be too heated, whether the display is safe when running, whether the LED display will have noise and whether it will affect people’s lives due to video switching, etc., these will become factors that people need to consider when studying outdoor small-pitch LED displays.

In short, outdoor small-pitch LED display is an inevitable trend in the development of the industry, especially the display screen with a pitch of about P2.5. There is a huge demand in the market, which is also the huge driving force for LED display manufacturers to develop outdoor small-pitch LED displays, and it is also the main reason why to do it.

Key Points And Difficulties of Outdoor LCD Signage Air Cooling System

LCD signage

Feedback from many a user: the LCD equipment is installed and the supplies are constantly fine, but in less than half a year, there is the output of various problems. After all, this is still a problem of thermal design and dust prevention. Due to the present market order, the digital outdoor signage industry is not large enough, with fierce competition, many manufacturers are not rigorous or intentionally exaggerated in the product specifications: such as, the maximum brightness of LCM is 2000nits for air-cooled and heat-dissipated outdoor LCD signage, the working temperature is -40~60 °C or more, the backlight light decay ≥ 50000h, the protection level reaches IP65, the working noise is less than 60dB…

Outdoor LCD signage, that is, the industry referred to as outdoor LCD advertising machine, is a subdivision of the commercial display industry. Since the product is installed for outdoor use, highlighting, protection, thermal design and reliability are the focus of the whole machine design. The earliest use of cabinet air conditioning for heat dissipation did solve the problem of heat dissipation, but due to factors such as product thickness, reliability, cost and power consumption, the industry continues to study new heat dissipation schemes to replace, air-cooled heat dissipation, heat exchange dissipation came into being.

TALKING ABOUT THE OUTDOOR LCD SIGNAGE USING AIR COOLING HEAT DISSIPATION, SUNTUNE FIRST USED THE AIR COOLING SOLUTION FOR THE WHOLE MACHINE HEAT DISSIPATION DESIGN IN 2012. From the earliest use of centrifugal fan design outdoor vertical landing 70-inch LCD machine heat dissipation, to the current outdoor 110-inch LCD machine using air-cooled heat dissipation, from single-screen heat dissipation to multi-screen splicing machine heat dissipation, from the earliest zero design experience to today’s professional whole machine system air-cooled heat dissipation a variety of schemes, multiple patents, familiar with various fan performance and selection, dust filtration, etc., these achievements are inseparable from the long-term learning and research of the R & D team, and always require high reliability and fast maintenance of products.

Installing LCD signage equipment for outdoor use, removing the structure and electronic control part, the biggest focus and difficulty is heat dissipation and dust prevention. If the thermal design is not done well, the common problems of outdoor LCD signage are: black screen in the sun, diaphragm wrinkle in high-brightness LCM, burst screen, mura, OC short-term yellowing, lines, burning T-con or backlight plate, fast light decay, high failure rate and so on. If the dust prevention is not done well, the outdoor cabinet will come in with a lot of dust. Dust into the front glass and LCM surface, it will affect the screen display effect, meanwhile increase the electronic components of a very high failure rate. Some boards are burned upon conduction because of the dust accumulation. Therefore, the key and difficult point for outdoor LCD signage is heat dissipation and dust prevention. However, many manufacturers fail to pay attention or don’t have the strength to solve the important factors which result in low product reliability and high failure rate.

In addition to rich thermal design theory and thermal simulation capabilities, professional designers must have comprehensive knowledge of structure, electronics, etc., and at the same time be familiar with the characteristics of various components of heat dissipation products and product temperature rise testing capabilities, only then can he formulate a perfect heat dissipation scheme for the whole machine. At present, because the outdoor LCD signage industry is a subdivision industry, large companies have not entered the industry, and the progress of technology needs to be expanded by talents of various companies, SUNTUNE looks forward to everyone’s efforts.
