Problems solved by technology

[0004] However, when the display device adopts the above-mentioned display panel, each display will drive all the pixels on the display panel to display. In some cases, if the user only needs to see the content displayed in a certain display area of ​​the display device ( For example, when the user only needs to watch the time displayed on the display device), the power consumption of the display device is increased

Embodiment Construction

[0030] In the gate drive circuit, the display device, and the driving method for sub-area display provided by the embodiments of the present invention, since the first control signal received by each shift register unit in the gate drive circuit at its own first control signal terminal is When the level is high, the gate line connected to itself will be connected to the low-level signal terminal, so that the gate line scanned after the gate line connected to the shift register unit can no longer be selected. When it is only necessary to view the content displayed in a certain display area of ​​the display device, the power consumption of the display device can be reduced.

[0031] The specific implementation manners of a gate driving circuit, a display device and a driving method for sub-area display provided by the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0032] A gate drive circuit provided by an embodiment o...

Abstract

The embodiment of the invention provides a grid driving circuit, a display device and a driving method for zoning display. The grid driving circuit, the display device and the driving method for zoning display are used for reducing power, of an existing display device, consumed when only the content displayed in a certain display area of the display device needs to be seen by a user. Each shift register unit in the grid driving circuit can make a grid line connected with the shift register unit be communicated with a low-level signal end when a first control signal received by the first control signal receiving end of the shift register unit is a high-level control signal, so that grating of grid lines scanned after the grid line connected with the shift register unit can not be achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate drive circuit, a display device and a driving method for sub-area display. Background technique [0002] The basic principle of TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Field Effect Transistor Liquid Crystal Display) to realize a frame display is to input a square wave of a certain width to each row of pixels sequentially from top to bottom through the gate drive. Perform gating, and then output the signals required by each row of pixels sequentially from top to bottom through source (source) driving. At present, the manufacture of display panels with such a structure is usually to make the gate drive circuit and the source drive circuit on the However, when the resolution is high, the output of the gate drive and the source drive are more, and the length of the drive circuit will also increase, which is not conducive to the bonding process...
