摘　　要：针对大屏幕液晶显示器的薄型化趋势,基于sol-gel法研究了一种新式薄型背光源沉降法涂屏技术.讨论了一次涂敷与二次涂敷性能、荧光粉表面形貌、膜厚与亮度的关系,获得了较好的屏制备条件,制作出了12.7 cm(5英寸)、亮度为65000 cd/m2的平面背光板.Large scale liquid crystal display is becoming thinner and thinner, slim back light device phosphor panel deposition technique by sol-gel method is discussed. Relation between first and second coating character were investigated. Thinness of coating and surface metrology was also studied. Optimized preparation processing of phosphor panel is achieved. 12. 7 cm （5 inch） flat panel backlight was made, the brightness is 65 000 cd/m^2.
