What is the emitting diode display? Led Display (English: LED Display) is a display using light -emitting diode, also known as "LED Panel" (LED Panel), HSCode: 85312000, which is widely used in information release, outdoor media, stadiums, large indoor display solution. In addition, it is also common in outdoor traffic instructions or display cards for public transportation.

Light diode

     Most outdoor and part of the indoor display are composed of multiple separate packaging diode. The light -emitting diode of red, green, and blue forms a set of square modules. The center point distance of the painting is determined. The world's large light -emitting diode display is more than 1,500 feet in length and is located in the Lyrich Street Lighting Show in Las Vegas, Nevada, USA.

     Most indoor displays use watch stickers SMT surface installation technology LED components (but there is a trend extending to the outdoor market). Each SMD pixel module contains multiple three -color diode in red, green, and blue in one installation, and then welded on the PCB board. The diode smaller than the needle is closely arranged. The display screen made by this display screen -encapsulated diode has better color consistency and reduces a small pixel distance by about 25%.

     The LED display used in the room generally has at least 600 CD/{\ DisplayStyle M^{2}} (candlelight/square meter, nits) brightness. There is a high screen brightness, such as fashion and automobile exhibitions, and stage lighting may need to be further improved. Relatively speaking. Video images require lower brightness and color temperature, but the color temperature of the general LED display is 6500-9000K, which is much higher than the need for video images. Outdoor use — It requires 5000 NITS, but it may take 8000 NITs to have strong light at a place where the sun is directly illuminated.

     Unlike ordinary consumption, commercial grade display devices (LCD, PDP, DLP, etc.), the "Lighting Diodes Display" belongs to industrial -grade equipment, and most of the "light emitting diode display" has been completed in engineering projects. The common display equipment is mostly used in the indoor environment, with low brightness, poor weather resistance, and short life.

     The brightness of the "light -emitting diode display" can even reach more than 10,000 nits, which can be fully waterproof, salt -proof, and dustproof, suitable for outdoor environment. At the same time, because the life span of the luminous diodes can reach 100,000 hours, the life span is much higher than the common display equipment. This is also the reason why the "light emitting diode display" is widely used in the field of transportation instructions and public transportation.

     From the perspective of luminous light, each pixel of the "emitting diode display" is an independent LED device. These devices are discharged and welded on the front PCB board of the product in a specific way. The brightness, itinerary, signal or image of a LED. All pixels are LED devices actively glowing. The ordinary display device is usually projected into a type of panel from the backlight source, and the image is displayed to varying degrees and methods by the special structure of the panel. Although PDP is actively glowing, it is based on small -area panels as standard products for production and sales.
