Embodiment Construction

[0042] A display device and a driving method thereof according to preferred embodiments of the present invention will be described below with reference to related drawings.

[0043] A method for driving a display device according to a preferred embodiment of the present invention, wherein the display device has at least one drive unit and a pixel array, and receives a pixel's zeroth display grayscale value and a first display grayscale value in time sequence a gray scale value, a second displayed gray scale value and a third displayed gray scale value. In this embodiment, the display device is a liquid crystal display device as an example. In addition, a zeroth time interval, a first time interval, and a second time interval described below are examples of temporal relationships, and the zeroth time interval, the first time interval or the second time interval is at least one frame time distance. In this embodiment, each of the zeroth time interval, the first time interval o...

Abstract

The invention relates to a display device and a driving method thereof, wherein the display device can be used for receiving a first display gray scale valve of a pixel and a second display gray scale valve of the pixel according to the time sequence, and the display device is at least provided with a driving unit and a pixel array. The driving method comprises the following steps: first, in a first time interval, according to the first display gray scale valve and the second display gray scale valve, outputting an overdrive valve into the driving unit from an overdrive comparison table for driving the pixel array, and judging whether the first display gray scale valve and the second display gray scale valve correspond to a compensation area of a compensation comparison table; and then, when the first display gray scale valve and the second display gray scale valve correspond to the compensation area of the compensation comparison table, in a second time interval, outputting a compensation driving valve into the driving unit for driving the pixel array.

Description

technical field [0001] The invention relates to a display device and a driving method thereof. Background technique [0002] With the development of display technology, display devices have been widely used by people. Among them, liquid crystal display devices 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 are used in many types of electronic products. [0003] Generally speaking, in order to enhance the edge contrast of the dynamic picture displayed by the liquid crystal display device, the industry uses an overdrive value to replace a target display gray scale value for the pixels that need to improve the contrast in the display device. For example, see figure 1 As shown, at a frame interval t 1 In , the target display grayscale value is replaced by the overdrive value, so that the grayscale brightness V displayed on the screen is 0 Excee...
