In recent years, with the expansion and penetration of LED display applications, the application competition of LED electronic displays and LCD splicing screens has become increasingly fierce. Today both can be applied in some situations, so how to choose? What are the differences and advantages between the two? Today, Dicolor will explain it to you in detail.

LED display, also called electronic display, is composed of LED dot matrix and LED PC panel. It displays text, pictures, animations, videos and content by turning on and off red, blue, white and green LED lights. It uses a low-voltage scanning driver and has the following characteristics: low power consumption, long service life, low cost, high brightness, few faults, large viewing angle, and long viewing distance.

It can display changing text, graphic images, numbers, and videos; it can be used not only in indoor environments but also in outdoor environments. It has advantages that LCD screens, projectors, and TV walls cannot match. 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 mines, transportation, education systems, auction houses, industrial enterprise management, and other public places.

The reason why LED display has received widespread attention and developed rapidly is inseparable from its own advantages. It has the following characteristics: high brightness, miniaturization, long life, low operating voltage, low power consumption, stable performance and impact resistance. The LED display has a vivid colors and a strong three-dimensional sense. It is as quiet as an oil painting and dynamic as a movie. The development prospects of LED are extremely broad. It is currently moving towards higher brightness, higher weather resistance, higher luminous density, and higher Luminous uniformity, reliability, and full-color development.

The LCD splicing screen adopts the splicing method of LCD display units and uses the splicing control software system to achieve a large-screen display effect. Currently, common splicing methods include 5.3mm 55-inch ultra-narrow-edge LCD splicing screen, 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 screens is generally only 250~300cd/m2, while the brightness of DID LCD screens can reach more than 700cd/m2. Because each point of LCD always maintains that color and brightness after receiving the signal, unlike CRT, which needs to constantly refresh the pixel points. Therefore, the LCD has uniform brightness, high picture quality and absolutely no flicker, making the picture more delicate when viewed at a close distance.

Compared with LED displays and LCD splicing screens, who is the real king of displays? We will know at a glance from the specific analysis of the following aspects.

1. Lifespan: The lifespan of LED is longer than LCD’s.

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

3. In terms of energy consumption: LED consumes much less energy than LCD, so LED is more environmentally.

4. In terms of brightness: LED have purer colors , a wider color gamut and higher brightness than LCD, which can increase the viewing angle of the display.

5. Viewing distance: LCD is suitable for close viewing, but at present, the point spacing of LED has reached 2mm, so close viewing is not a problem for it anymore.

6. The backlight LED display uses light-emitting diodes, while the LCD splicing screen uses cold cathode ray tubes. In terms of price, LCD is cheaper.

So choosing between the two products depends on your scope of use and requirements. LCD is a liquid crystal screen with relatively low brightness, suitable for indoor viewing within ten meters. It is mostly used in monitoring centers or video conferencing. LED is composed of countless light-emitting diodes with a large dot pitch. It is suitable for viewing outdoors or at a distance. The indoor screen brightness can reach 1000 -2000 nits, different model have different brightness, and the optimal viewing distance can reach 6-80 meters, which is suitable for use in larger venues. However, since the pixel pitch of LED displays has reached 2mm, LED electronic displays have now entered the field of monitoring, and the application fields of displays will continue to expand in the future.
