为满足轻薄化的需求, 越来越多的液晶显示器应用了侧背光的背光系统。通过仿真, 分析了导光板厚度以及进光面与LED背光间距对于显示器亮度的影响, 同时提出了导光板进光面点胶的方法以提高背光的光效。经过试验验证, 该方法能有效提高显示器的亮度。

In order to meet the requirement of being lighter and thinner, more and more liquid crystal displays (LCD) use the edge-light as backlight systems. Through simulation, the influence of the thickness of light guide plate(LGP) and LGP-to-LED distance on display brightness was analyzed, and a method was proposed to improve luminous efficiency by dispensing on in-light surface of LGP. The experiment shows that this method can effectively enhance the display brightness.
