Chinese enterprises have mastered the core technology of LED backlight

For nearly one or two years, Hisense, Konka, SKYWORTH and other domestic brands have launched LED TV, but the light will be purchased or not mass production of the brand products. At present, the traditional color TV manufacturers have increased investment, into the field of LED backlight module. As the LCD TV panel patents are mainly concentrated in the hands of the Japanese and Korean companies, backlight technology has become the main goal and opportunities for Chinese enterprises to enter the upper reaches. Belong to the LED module two processing, and did not really grasp the core technology.

China as one of the first to enter the LED industry, Tsinghua Tongfang has become the first to master the first A new force suddenly rises., LED back light module for the core technology of the enterprise China, the 17 inch to 57 inch LED backlight module has the full realization of production, has become the main market for LED backlight to be one.

At present, Tsinghua Tongfang has formed a LED epitaxial wafer, chip manufacturing and packaging, terminal products production and application, to the city landscape lighting complete industrial chain and large-scale production, and has manufacturing patented LED epitaxy and chip of nearly 30.

Semiconductor device according to the national quality supervision and inspection center of the testing results show that the Tongfang LED product performance is very excellent, reached the international advanced level, fully meet the technical requirements of high-end LED chip products.

"Through research and development in recent years, the breakthrough of Tsinghua Tongfang LED back light source, the cost of large-scale manufacturing efficiency, brightness uniformity control, mastered the key technology. Four LED backlight LCD module production line officially entered the stage of mass production. Liu Gang, deputy general manager of the same side of the semiconductor and lighting industry, said the company has made significant progress in high-power chip research and development, a significant improvement in the process of the chip significantly improved the luminous efficiency and yield.
