(2) led by color into monochrome monochrome screen how much a square meter, two-color, three-color (full color) monochrome display means only one color of light-emitting materials, mostly single red, in some special applications can also be yellow-green (for example, the funeral home). Dual color LED display by the red and green LED lights composition, 256 gray two-color display can display 65,536 colors (color screen can display red, green, yellow 3 colors). Full-color LED display by the red, green and blue LED lights composition, white balance and can display 16,777,216 colors. 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. Now Indoor LED monochrome screen, high brightness AlGaInP, TS-AlGaAs, InGaN LED has been able to provide a bright red, yellow, green and blue colors can be realized fully meet the requirements of full-color large-screen display. LED display assembly into a variety of structures according to the pixel size, smaller pixel diameter generally less than 5mm, each pixel with a T-1 (3/4) of the LED lamp monochrome display, each pixel of the color display for color T-1 (3/4) of the price of LED lights led monochrome screen, full-color display requires three T-1 red, green, and blue lights, or a multi-chip assembly of T-1 (3/4) of 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. p10 monochrome screen | Yasuhiro photovoltaic (certified) | Qingdao monochrome screen provided by Linyi Wang Tai Electronics Limited.
