Full-color LED display has the advantage of a large screen display features, specific characteristics of the advantages of a large screen in the end, what does? Xiaobian compiled some relevant information, let's work together to understand it!

Large screen display is another huge market high brightness LED applications, including: graphics, text, digital monochrome, color and full color display. Table 2 lists the various uses LED display. Traditional large-screen active display commonly used incandescent lamp, fiber, cathode ray tubes; passive displays commonly used method flop.

LED display LED itself has been limited by the 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 achieve full-color fully meet the requirements of large-screen display. LED display pixel size can be assembled into a variety of structures, smaller pixel diameter generally less than 5mm, for 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 LED lights as a pixel .

Large pixel is through the many T-1 (3/4) of red, green, and blue LED combined configuration. With InGaN (480nm) blue, InGaN (515nm), green and ALGaAs (637nm) LED display red LED lights as three primary colors, can provide realistic full-color performance, but with a larger range of colors including: blue-green, green, red, etc. , and the International System Committee (NTSC) color television TV predetermined range basically.
