Abstract

The invention discloses a display device comprising a display panel, a grid drive circuit and a source drive circuit. The display panel comprises multiple pixel units which are arranged according to rows and columns, multiple grid scanning lines which are arranged according to the rows, multiple compensation potential lines which are arranged according to the rows and multiple source data lines which are arranged according to the columns. Each pixel unit comprises a thin film transistor, a pixel electrode and a compensation capacitor. The grid drive circuit is used for providing grid voltage to the grid electrodes of the thin film transistors of the pixels of the corresponding row. The source drive circuit is used for providing source voltage to the source electrodes of the thin film transistors of the pixels of the corresponding column so as to set display voltage between the electrode plates of a liquid crystal capacitor. The grid drive circuit comprises multiple grid drive circuits. Each grid drive unit comprises a compensation module and is used for providing compensation voltage to the compensation capacitors of the pixels of the corresponding row in multiple pixels according to a front grid drive signal and a rear grid drive signal. According to the display device, compensation of feed-through voltage can be realized through the grid drive circuit, the compensation capacitors and the compensation potential lines.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display device. 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 and 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 display panel 110, a first glass substrate 110a and a second glass substrate 110b, the first surface of the first glass substrate 110a is opposite to the first surface of the second glass substrate 110b. A plurality of gate...
