  • Driving method for liquid crystal display device
    Patent number: 11315509
    Abstract: A driving method for a liquid crystal display device is provided. The liquid crystal display device has a wide viewing angle mode and a narrow viewing angle mode. The driving method includes: in the wide viewing angle mode, all the frames of the liquid crystal display device have the same display brightness; in the narrow viewing angle mode, the odd frames and the even frames of the liquid crystal display device have different display brightness. In the narrow viewing angle mode of the liquid crystal display device, by using an alternate driving method of bright frames and dark frames, the mura degree is significantly reduced, and the smoothness of dynamic picture display is improved, thereby improving the use experience of users.
