Who is the king of screen display in the competition between LED display screen and LCD splicing screen


With the expansion and penetration of the application scope of LED display screen, the application competition between LED electronic display screen and LCD splicing screen is becoming increasingly fierce. Today, both can be used in some situations, so how to choose? What are the differences and advantages between the two? The following information will give you a detailed answer.

LED display screen, also called electronic display screen, is composed of LED dot matrix and LED pc panel. It displays text, pictures, animation, video and content by turning on and off red, blue, white and green LED lights. It adopts low voltage scanning drive, and has the following characteristics: less power consumption, long service life, low cost, high brightness, few failures, large viewing angle, long visual distance, etc. It can display changing text, graphics, images, numbers and videos; It can be used not only for indoor environment but also for outdoor environment, with incomparable advantages of LCD, projector and TV wall. It is also widely used in stations, docks, airports, hotels, banks, securities markets, construction markets, taxation, shopping malls, hospitals, finance, industry and commerce, post and telecommunications, sports, advertising, factories and mining enterprises, transportation, education systems, auction houses, industrial enterprise management and other public places.

The reason why LED display is widely valued and rapidly developed is inseparable from its own advantages. It features high brightness, miniaturization, long service life, low operating voltage, low power consumption, stable performance and impact resistance. LED display screen has bright colors and strong stereoscopic sense, which is as static as oil painting and as dynamic as film. LED has a very broad development prospect. At present, it is developing towards higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability and full-color.

The LCD splicing screen is a splicing screen body that uses the splicing method of LCD display units to achieve the large screen display effect through the splicing control software system. At present, common splicing methods include 5.3mm 55 inch ultra narrow edge LCD splicing, 6.7mm 46 inch ultra narrow edge LCD splicing screen, 47 inch LCD splicing, 60 inch LCD splicing wall and 40 inch narrow edge LCD splicing system.

Compared with TV and PC LCD screens, LCD splicing screens have higher brightness. The brightness of TV or PC LCD screen is generally only 250~300cd/m2, while the brightness of DID LCD screen can reach more than 700cd/m2. Since every point on the LCD keeps that color and brightness after receiving the signal, unlike CRT, it needs to refresh pixel points constantly. Therefore, the LCD has uniform brightness, high image quality and absolutely no flicker. When viewed from a close distance, the picture is more delicate.

Compared with LCD splicing screen, LED display screen is the real king of screen display, which can be seen at a glance from the following aspects.

Service life The service life of LED is longer than that of LCD.

Refresh rate The refresh rate of LED is higher than that of LCD, and the response speed is faster.

In terms of energy consumption, LED is much lower than LCD in terms of energy consumption, so LED is more environmentally friendly.

In terms of brightness, LED has more pure color, wider color gamut and higher brightness than LCD, which can increase the viewing angle of the display screen.

Viewing distance: LCD is suitable for close viewing, but at present, the distance between LED dots has reached 2mm, and close viewing is not a problem.

LED backlight source screen uses LED lamp, LED, and LCD splicing screen uses cold cathode ray tube. In terms of price, LCD is cheaper.

Therefore, the choice between the two depends on the specific scope and requirements of use. LCD is a kind of LCD with low brightness, which is suitable for indoor viewing within 10 meters. Most of them are used in monitoring centers or video conferences. LED is composed of numerous light-emitting diodes with large dot distance, which is suitable for outdoor viewing or viewing at a distance. The brightness of indoor screens can reach 1000-2000 models with different brightness, and the optimal viewing distance can reach 6-80 meters, which is suitable for use in large venues. However, as the point spacing of LED display has reached 2mm, LED electronic display has entered the monitoring field, and the application field of display will continue to expand in the future.
