摘要
Abstract
This paper analyzes the LED(Light Emitting Diode) backlight's advantages and disadvantages, then proposes new design method of side-emitting LED backlight .In this design, CCFL(Cold Cathode Fluorescent Lamps) light source is replaced by LED and micro-optical guidepipe, LED converts into linear light source through guidepipe.The side-emitting LED backlight applied in large-size LCD products has many anwantages , such as it can reduce the number of light source, retain the advantages of designing the Light Guide Plate and avoid the shortcomings of CCFL simultaneously.The analysis shows that the efficiency is above 69％ and the uniformity is better than 98％.The new backlight can significantly reduce costs, increase display, so it has broad development prospects and application space.关键词
