LED and LCD are two completely different light-emitting technologies; the former is light-emitting diode positive light, the latter is liquid crystal backlight light. Both technologies are widely used in mobile phones, TVs, commercial displays and other fields. Here’s SUNTUNE’s lay down analysis of the differences between these two for business applications.

1. LED displays compared to LCD displays in visual effect
LED display is composed of a number of 320mm*160mm (conventional size) LED units, regardless of size, can be infinitely spliced without splicing gaps, so the screen customization is high and the picture integrity is very good. LCD splicing screen is composed of several LCD units. The LCD unit specifications are usually 49 inches, 55 inches, 65 inches, etc. To choose the units properly, it needs to refer to the specifications of the entire screen. Besides, the picture integrity is not so good because of the splicing gaps.

2. In brightness
The brightness of LEDs is in the range of 800 to 6000 Nits, while the brightness of LCD is 250-1500 Nits. LCD screen gets low in brightness, not suitable for outdoor or the indoor with strong light. LED display, however, is not limited by light intensity and can be used both indoors and outdoors.

3. The power per square meter of conventional LED display is about 450W-800W according to the difference between dot spacing and other parameters, and the power per square meter of conventional LCD screen is about 350W, and the power consumption per square meter of normal use of LED display is greater than that of LCD screen. In specific places, the brightness of the LED display can be turned down so to reduce power consumption.

4. The LED is emitting light through the chip, and the color saturation is high. The LCD is through its backlight, and the color reproduction is average, plus each liquid crystal unit will have a certain color difference, resulting in the overall color general.

5. See it up close
For example, when viewing a screen within 1 meter, the LCD screen has delicate picture quality and high definition. The lamp beads of the LED display are obviously grainy and the clarity is average. However, standing at a normal visual distance of 2 meters away, there is little difference in image quality between the two. Of course, the clarity of the picture quality is also related to the model of the LED display, and the close-up picture quality of the small-pitch LED display is very clear.

6. In functions
Actually, the two are only used as a display function, there is no essential difference. Both have the function of playing videos, pictures, PPT and other materials.

So to sum up, LED or LCD, which one do you think is better? In fact, the most suitable is the best. Stay tuned for a separate SUNTUNE post on how to pick the right LCD display!
