DISPLAY DEVICE

摘要

A controlling method of a display device is provided. The display device includes an optical modulating panel with an optical modulating layer and a display panel with a display layer. Firstly, a viewing position is sensed, and an azimuthal angle and a polar angle of the display device with respect to the viewing position are obtained accordingly. Then, an orientation mode of the display device is judged according to the azimuthal angle. Then, one of the optical modulating layer and the display layer is selectively adjusted according to the orientation mode and the polar angle of the display device.
