With the rapid development of electronics industry, display technology was greatly developed in the 1960s, and PDP, LCD and other displays came out one after another.In the 1980s, with the rapid development of computer technology, the CGA (Color GraphtcsAdapter) display format came out with an accuracy of 320 x 200 (4 colors).At present, the display technology is developing in the direction of ultra-high resolution. The display precision has been developed from the earlier 320 x 200 to l 600 x l 250, 4 kinds of display color music have been developed to 32 real color, and the scanning frequency has been changed from l 5.7kHz raised to 150kHz.The projector is a large screen display device, but it cannot be used in natural light.Due to the appearance and development of high-brightness LED, LED display came into being in the late 1980s of the 20th century, and it has been widely used in the world.In a short period of 20 years, 9 LED display technology and production have made great progress, and now has developed into an important modern letter, BR cloth media means and one of the mainstream products of flat panel display.
