Optical peep-proof display design method based on color film substrate design

The invention discloses an optical peep-proof display design method based on color film substrate design. The method comprises the steps: additionally arranging a plano-convex lens Lens at the CF sideof a color film so as to control the emergent light direction of the sub-pixel dot in each pixel pixel pixel, thereby controlling the maximum angle of mixed light after dot emergence, and achieving peep prevention. According to the design method, peep-proof display can be achieved, different maximum visual angles can be designed according to different using environments, practicability is high and the peep-proof effect is good. 本发明公开了一种基于彩膜基板设计的光学防窥显示设计方法，包括通过在彩膜CF侧增设平凸透镜Lens，以控制从每个像素pixel中的子像素dot出射光方向，从而控制dot出射后混合光的最大角度，实现防窥。该设计方法可以实现防窥显示，并且可以根据不同的使用环境，设计不同的最大可视角度，实用性强，防窥效果好。
