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 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 LED lights, full color display requires three T-1 red, green, and blue light, or a multi-chip assembly of T-1 (3/4) of the LED lamp 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) red LED lamp as trichromatic LED display, can provide a realistic full color performance, and control rate is the minimum pixel unit of the display image (pixels) does not work properly (runaway) proportion. The pixel control has two modes: one blind spot, which is the blind spot, at the time that it does not need bright light, called the blind spot; the second is often the highlight of the day the door · LED display production, the need does not shine when it but has been lit, often referred to as highlights. In general, the composition of the pixels have 2R1G1B (2 颗 red, one green and one blue light, following the same token), 1R1G1B, 2R1G, 3R6G etc. Suizhou LED display production, and loss of control is generally not the same pixel in the red, green and blue light at the same time all the runaway Honghu LED display production, but as long as a lamp out of control, we believe that this pixel control. For simplicity, the pixels of each color (red, green, and blue) were out of control pixel statistics and calculations, take the highest value as we press the LED display screen control rate.
