| 摘 要： | 基于Taguchi实验方法和Tracepro仿真软件,研究了 Mini LED背光模组中LED芯片大小、芯片发光半角、芯片出光面到液晶层的距离等因素,对液晶面板照度均匀性的影响规律并对其进行了相应分析.研究结果表明:芯片出光面到液晶层的距离对照度均匀性影响最大,影响因素的权重占比达到82.88％;发光半角占比14.33％:芯片大小占比为14.33％.根据研究结果,固定发光半角与芯片尺寸,调节出光面与液晶面板层的距离,得到了最优的照度均匀度.

| Abstract: | The influence of the factors such as the LED chip size, the emission half Angle and the distance from the luminous surface to the LCD panel layer in Mini LED backlight modules, on the illumination uniformity of the LCD crystal panel was studied and analyzed with Taguchi experimental method and Tracepro software. The results show that the distance from the luminous surface to the liquid crystal layer has the greatest influence on the illuminance uniformity, and the weight of the influencing factors is 82.88%, and that of the luminous half angle and the chip size is both 14.33%. According to the research results, the optimal illumination uniformity is obtained by fixing the luminescence half angle and the chip size and adjusting the distance between the luminous surface and the LCD panel layer. |
