侧背光式三色RGB LED混色技术研究

A Research on RGB LED Color-mixing Technology of Edge Backlight System

针对侧背光三色RGB LED混色不均匀的问题,在常见侧背光RGB LED排布方式的基础上,提出了一种新型侧背光方式。采用LightTools光学软件进行仿真,得到了出光面色坐标分布。最后设计制作侧背光灯条,进行实验,实验与仿真结果一致,显示该方案能够较好的改善三色RGB LED的混色问题。

With respect to the uniformity in the color-mixing of RGB LED of edge backlight system, a new method for edge backlight is proposed based on the normal distribution methods. Chromaticity distribution of the display plane was modeled and simulated with optical software LightTools. The edge back lights were designed and the experiment showed a good result that the proposed method could improve the RGB LED color-mixing technology of edge backlight system.
