LED color LED with a material different manufacturing process, can produce photons car led monochrome screen of different energies, whereby to control the wavelength of light emitted by the LED, i.e. the spectral or color. 1. History of a material used in LED arsenic (As) of gallium (Ga), the PN junction forward voltage drop (VF led monochrome screen manufacturers, can be understood as light or voltage) is 1.424V, issued infrared light spectrum. 2. Another commonly used material for LED phosphorus (P) gallium (Ga), the PN junction forward voltage drop of 2.261V, the light emitted green light. Large screen display is another huge market for high brightness LED applications, including: graphics, text, digital monochrome, color and full color display. Table 2 lists the various uses LED display. The traditional large-screen active display commonly used incandescent lamp, fiber, cathode-ray tubes; passive displays commonly used method flop. Table 3 compares the performance of several displays. LED display LED itself has been limited performance and color. Today, high brightness AlGaInP, TS-AlGaAs, InGaN LED has been able to provide a bright red, yellow, green and blue colors of the screen manufacturers can realize fully meet the requirements of full-color large-screen display. Each pixel LED display pixel size can be assembled into a variety of configurations, generally less than 5mm in diameter small pixel monochrome screen, each pixel monochrome display with a T-1 (3/4) of the LED lamp, two-color display for the color of the T-1 (3/4) of the LED lights, full color display requires three T-1 red, green, and blue lights, or a multi-chip assembly of T-1 (3/4) LED lights As a pixel. Large pixel is by many T-1 (3/4) red, green, and blue light are combined to make the LED. With InGaN (480nm) blue, InGaN (515nm), green and ALGaAs (637nm) LED display red LED lights as the three primary colors, can provide a realistic full-color performance, but with a larger range of colors including: blue-green, green, red, etc. with the International System Committee (NTSC) TV provides television color range basically.
