Problems solved by technology

Moreover, for the sake of image quality, the dual-gate pixel architecture is usually driven with column inversion or row inversion, but this will also bring about the problem of bright and dark lines at low gray levels

Abstract

The invention discloses a display device and a driving method thereof. The driving method comprises the following steps: first, the positive and negative polarity changes of a picture of a current frame and a picture of a next frame of a pixel array are compared; then, whether a first overvoltage drive lookup table or a second overvoltage drive lookup table is applicable is judged, the first overvoltage drive lookup table is applicable if there is no positive and negative polarity switching between the picture of the current frame and the picture of the next frame, and the second overvoltage drive lookup table is applicable if there is positive and negative polarity switching between the picture of the current frame and the picture of the next frame; a gray scale voltage difference is determined according to the applicable first overvoltage drive lookup table or second overvoltage drive lookup table; and next, overvoltage driving is performed on the pixel array with the gray scale voltage difference. The driving method provided by the invention can improve the problem of bright and dark lines under a low gray scale and improve the picture quality.

Description

technical field [0001] The present invention relates to a driving technology of a display device, in particular to a display device with a double gate structure and a driving method. Background technique [0002] In recent years, with the advancement of technology, many different display devices, such as Liquid Crystal Display (LCD) or Electroluminescent Display (ELD) display devices, have been widely used in flat panel displays. Taking a liquid crystal display as an example, most of the liquid crystal displays are backlight liquid crystal displays, which are composed of a liquid crystal display panel and a backlight module. A liquid crystal display panel is composed of two transparent substrates and a liquid crystal sealed between the substrates. [0003] Existing liquid crystal displays usually provide data signals through a plurality of pixel electrodes respectively according to image information, and control the light transmittance of the plurality of pixel units to dis...
