Problems solved by technology

However, this solution is based on the design of circuit structure and function, if the simulation calculation is inaccurate, the compensation effect will even be counterproductive
This precompensation scheme also does not allow modification after product packaging, thus limiting its scope of application

Abstract

The invention discloses a liquid crystal display device and a driving method therefor. The device comprises a pixel array which comprises a plurality of pixels arranged in rows and columns, wherein each pixel comprises a thin film transistor, pixel capacitors, and liquid crystal molecular layers located among the pixel capacitors; a grid drive circuit which is connected with a plurality of grid scanning lines, and is used for providing grid voltages according to the grids of the thin film transistors of the pixels in the corresponding row; and a source electrode drive circuit which is connected with a plurality of source electrode data lines, and is used for providing the source electrode voltages for the thin film transistors of the pixels in the corresponding columns so as to set the display voltage across pole plates of the pixel capacitors. The device drives the pixels row by row in each frame period, and compensates the source electrode voltages according to the feed through voltage differences between different pixels. The device improves the image quality through the compensation of feed through voltage differences between different pixels.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a liquid crystal display device and a driving method thereof. Background technique [0002] A liquid crystal display device is a display device that uses the phenomenon that the alignment direction of liquid crystal molecules changes under the action of an electric field to change the light transmittance of a light source. Liquid crystal display devices have been widely used in mobile terminals such as cell phones and large-sized display panels such as flat TVs. [0003] figure 1 with 2 A schematic structural diagram and an equivalent circuit diagram of a liquid crystal display device according to the prior art are respectively shown. The liquid crystal display device 100 includes a first glass substrate 110 and a second glass substrate 210 , the first surface of the first glass substrate 110 is opposite to the first surface of the second glass substrate 210 ...
