AI Technical Summary
Technical Problem
The brightness of existing display panels decreases and the viewing angle cannot be adjusted arbitrarily after attaching a light control film, and the light control film also degrades the image quality.
Method used
By setting multiple light control pillars in the display panel, the propagation of light is controlled by voltage, and the vertical viewing angle, horizontal viewing angle, or a combination thereof is adjusted, thus avoiding the use of light control film.
Benefits of technology
It enables flexible adjustment of the display panel's viewing angle without sacrificing brightness, thus improving image quality.
