Abstract

The invention relates to a liquid crystal display device and a driving method thereof. The liquid crystal display device includes a liquid crystal display panel, a backlight module, and a control circuit. The liquid crystal display panel includes n display areas, and the backlight module includes n backlight areas corresponding to the n display areas one-to-one. n is a natural number greater than or equal to 2, Each backlight area is used to provide backlight to a corresponding display area, and the control circuit is electrically connected to the liquid crystal display panel and the backlight module, and is used to sequentially scan n display areas and apply corresponding grayscale voltage signals to n display areas and control For the light emission of n backlight areas, when the i-th display area is scanned, the i-th display area is applied with the corresponding grayscale voltage signal, the i-th backlight area corresponding to the i-th display area is turned off, and the i-th display area All the backlight areas other than the two backlight areas are turned on, and i is a natural number greater than or equal to 1 and less than or equal to n.

Description

technical field [0001] The invention relates to a liquid crystal display device and a driving method thereof. Background technique [0002] With the advancement of technology, flat panel display devices have been widely used in various fields, especially liquid crystal display devices, which have gradually replaced traditional cathode ray tube display devices due to their superior characteristics such as light and thin body, low power consumption and no radiation. , and applied to many types of electronic products, such as mobile phones, portable multimedia devices, notebook computers, LCD TVs and LCD screens, and so on. However, due to the retention characteristics of liquid crystals, liquid crystal displays are prone to motion blur when displaying dynamic images. Contents of the invention [0003] A liquid crystal display device, which includes a liquid crystal display panel, a backlight module and a control circuit, the liquid crystal display panel includes n display a...
