摘　　要：将液晶显示器背光模块的导光板向前延伸5mm,利用该区设计一扩光区使得LED点光源经过该区可获得两次的扩光效果,达到将点光源转成近似冷阴极管(CCFL)的线光源效果,并以3in液晶显示器面板进行模拟,模拟结果表明导光板的出光均匀度可以达85%以上。By extending light guide plate of liquid crystal display backlight module for 5 mm forward,we designed a light expanding area. When LED light source passed this area, twice light expansion was obtained. So that the LED spot light source can be transfered to line light source of CCFL approximately. A 3-inched liquid crystal display panel was simulated. The result shows that the light output uniformity of the light guide plate is over 85G.
