LED over the years has been subject to the limitations of color and luminous efficiency, but because of GaP and GaAsP LED with long life, high reliability, operating current is small, with many of the advantages of TTL, CMOS digital circuits compatible and therefore has been subject to the users of the green squint.

The last decade, high-brightness technology, full-color has been the topics at the forefront of LED materials and device technology. The ultra-high brightness (UHB) is the luminous intensity to meet or exceed 100mcd the LED, also known as the candela (cd) level LED. High-brightness InGaN LED A1GaInP and development has progressed very rapidly and has now reached the conventional materials GaA1As, GaAsP, GaP can not reach the level of performance.

The development of LED started in the 1970s, the industry in the 1980s.

There are about 100 enterprises,Bluetooth keyboard device 95% of manufacturers are engaged in the production of post-Road package, the required die almost entirely imported from abroad. Several "Five-Year Plan" technological innovation, and technology research, the introduction of foreign advanced equipment and some key technologies, China's LED production technology has stepped forward a step.
