| 摘 要： | 针对大尺寸LCD直下式背光模组的均匀性问题提出了一种无缝平凹透镜阵列,用以代替常用的扩散膜。模拟了106.68mm(42in)LED背光源的光学分布,得到了合适的透镜半径、结构以及LED阵列间距,分析了平凹透镜阵列半径和平凹透镜阵列与光源的相对位置对匀光作用的影响。结果表明:半径为1mm、厚度为2mm的无缝平凹透镜阵列较好地起到了匀光的效果,接收面的照度均匀性为88.61%。

| Abstract: | In order to improve the uniformity of the LCD backlight,a kind of plano-concave lens array was used in straight down type LCD backlight module instead of the diffusion films.For 106.68 mm(42 in) LCD monitor LED backlight,the illuminance distribution was simulated,and the optimized lens radius,structure,distance of LED array were determined.The effect of different lens radius and lens array position on the uniformity of backlight was also discussed.The results show that the plano-concave lens array can diffu... |
