Embodiment Construction

[0046] In an existing display panel, such as Figure 1a As shown, it includes 4N gate lines, the first gate drive circuit GOA1 connected to the 4n+1th gate lines (gate1, gate5, gate9...) on one side of the display panel and the 4n+3th gate lines ( gate3, gate7, gate11...) connected to the third gate drive circuit GOA3, located on the other side of the display panel and connected to the 4n+2th gate line (gate2, gate6, gate10...) The second gate drive circuit GOA2 and The fourth gate drive circuit GOA4 connected to the 4n+4 gate lines (gate4, gate8, gate12...), and the gate drive circuits (GOA1, GOA2, GOA3 and GOA4) connected to at least The pole drive circuit outputs a drive control circuit 1 corresponding to a group of timing control signals; wherein, n is an integer greater than and equal to 0 and less than N; each group of timing control signals includes at least a trigger signal and a clock signal, and each group of timing The widths of the trigger signals in the control si...

Abstract

The invention discloses a driving method for a display panel, a display panel and a display device. Compared with the existing display panel, the display panel disclosed by the invention has the advantages that a mode switching circuit controls a driving control circuit to drive all grid driving circuits to output a scanning signal in sequence to each first grid line group represented by every two adjacent grid lines along the scanning direction when receiving a first mode control signal; and/or the mode switching circuit can control the driving control circuit to drive all the grid driving circuits to output a scanning signal in sequence to each second grid line group represented by every four adjacent grid lines along the scanning direction when a second mode control signal is received. Therefore, in specific application, the mode control signal is sent to the mode switching circuit of the display panel as required, and the resolution of the display panel is controlled to be reduced to 1/2 or 1/4, so that the power consumption of the display panel can be reduced, and the standby time is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a driving method of a display panel, a display panel and a display device. Background technique [0002] In today's era of rapid technological development, liquid crystal displays have been widely used in electronic display products, such as televisions, computers, mobile phones and personal digital assistant devices. The liquid crystal display includes a data driver (Source Driver), a gate driver (Gate Driver), and a liquid crystal display panel. The liquid crystal display panel has a pixel array, and the gate driving device is used to sequentially turn on the corresponding pixel rows in the pixel array, so as to transmit the pixel data output by the data driver to the pixels, and then display the image to be displayed. [0003] At present, the gate driver is generally formed on the array substrate of the liquid crystal display through an array process, that is, the gate drive...
