基于偏振片的显示器视角窄化研究

Research on Display Viewing Angle Narrowing Based on Polarizer

设计了一种新型偏振片,通过加入防窥层,实现了一种具有窄视角功能的偏振片。以防窥层的光栅片将大角度的光挡住,只保留较小角度的光线,达到防窥的作用。研究结果表明,提出的具有窄视角功能的新型偏振片可以将显示器的可视角度从160°降低到60°。

In view of the need to protect privacy in public places,special displays need to have narrow viewing angle function,and a new type of polarizer was designed.By adding anti-peeping layer,a polarizer with narrow viewing angle function was realized.By using the anti-peeping layer grating slice to block the large angle of light and retain the small angle of light,the purpose of anti-peeping was achieved.The results showed that the proposed new polarizer could reduce the viewing angle of the display from 160°to 60°.
