Topic: Industry Crystal Power (2448) Zhang Shixian, deputy general manager, said that LED chips are out of stock and have spread from high-end chips to smaller chips. He also revealed that at the current stage of demand from manufacturers, crystal electricity can only meet 50% to 60%.
At present, even low-end LED chips are lacking. The medium and high-end chips that originally supplied mobile phones are about 1800~2000mcd. Many manufacturers have developed to 2000~2400mcd. After these high-orders are turned to high-end, like white-handed mobile phones and fluorescent lamps in the Chinese market. Chips such as tubes have also been out of stock.
As a result, the current business pressure of the LED epitaxial plant has increased, and we must try to meet customer needs. There have been expansions in the field of crystal power. In April, 3 to 4 MOCVDs could be added. In 2010, Q2 will increase production capacity by 10 to 15%.

For the LED backlighiting keypads, the graphic overlay lighted by the backside LEDs which assembled on the flex or rigid circuit layer. By this way, it is very simple and also economical. But it couldn't get a even lighting effect on surface. For this backlighting method, the LEDs can be assembled under centered buttons also can be assembled beside of the buttons or other areas. For the products need each button be backlighted, usually design the LEDs under the center of the buttons, then use the center holed metal domes and print transparent color on the graphic overlay. By this way the center button will be much brighter than sides of it. But this way is easy to achieve and also its cost is the lowest. This is suitable for those products no very high requirement for the evenness of the backlighting.
