Abstract

The invention relates a liquid crystal display device and a driving method thereof. The driving method of the liquid crystal display device provided by the invention comprises steps of transmitting image data to the liquid crystal display device via first frequency, processing the image data to generate bright area images according to the first frequency and a first gamma lookup table, transmitting the image data to the liquid crystal display device via the first frequency and processing the image data to generate dark area images according to the first frequency and the first gamma lookup table, sequentially superposing the bright area images and the dark area images, and displaying the images on a display panel of the liquid crystal display device.

Description

technical field [0001] The present invention relates to a liquid crystal display and its driving method, and in particular relates to a liquid crystal display and its driving method which can improve the large-view angle deviation phenomenon of the liquid crystal display. Background technique [0002] Liquid Crystal Display (LCD) has gradually become the mainstream of the market due to its superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation. At present, the performance requirements of the market for liquid crystal displays are high contrast (High Contrast Ratio), fast response, and wide viewing angle. Currently, the technologies that can meet the wide viewing angle requirements include: Multi-domain Vertical Alignment (Multi-domain Vertical Alignment, MVA), Multi-domain Horizontal Alignment (MHA), Twisted Nematic plus wide viewing film (TN+film), In-Plane Switching (IPS) and other technologies.
