【摘要】：从几何光学的角度设计并实现高动态范围视频显示系统的背光模组。首先明确背光模组亮度均匀性对高动态范围视频显示系统的重要影响,并通过斯派罗法则确定背光模组LED光源的间距、混光距离等设计参数,随后利用AutoCAD软件进行三维建模,利用TracePro、LightTools光学软件进行仿真实验,并通过改造现有显示屏幕的背光模组来实现高动态范围视频显示系统。结果显示:设计与实现的背光模组能够达到高动态范围视频显示系统的要求,液晶面板的峰值亮度可达2500cd·m-2,亮度均匀性为95.85%。
[Abstract]:The backlight module of high dynamic range video display system is designed and implemented from the angle of geometry optics. Firstly, the important influence of brightness uniformity of backlight module on high dynamic range video display system is defined, and the design parameters such as the spacing of backlight module LED light source, the distance of light mixing and so on are determined by Sparrow rule. Then the 3D model is built by using AutoCAD software. The simulation experiment is carried out by using TracePro,LightTools optical software, and the high dynamic range video display system is realized by modifying the existing backlight module of the display screen. The results show that the designed and implemented backlight module can meet the requirements of high dynamic range video display system. The peak brightness of liquid crystal panel can reach 2500cd m-2, and the brightness uniformity is 95.85.
