AI Technical Summary
Existing liquid crystal dimming films are inadequate in achieving true black in images and controlling side lighting, resulting in degraded image quality and reduced brightness.
A viewing angle control component comprising a liquid crystal layer and a light-shielding pattern is employed. The orientation of liquid crystal molecules is controlled by an electric field to achieve private and shared modes. The scattering characteristics are reduced by utilizing the refractive index change of the liquid crystal layer and the optical path control of the light-shielding pattern.
It achieves high brightness front visibility in private mode and side visibility in shared mode, improving image quality and brightness, and solving the problems of true black and reduced brightness in liquid crystal dimming films.
