DRIVE CIRCUIT, DISPLAY PANEL, DISPLAY DEVICE AND DRIVE METHOD

摘要

A drive circuit of a display panel, a display panel, a display device and a method of driving a display device are provided. The circuit comprises: j select circuits and j data line signal output circuits, j is an integer greater than or equal to 2. Each data line is connected with a select circuit, different data lines are connected with different select circuits, each select circuit is connected with the j data line signal output circuits, each select circuit can control the data line connected therewith to be connected with one of these j data line signal output circuits and to control the data line connected therewith to be disconnected from the other ones of these j data line signal output circuits; so pixels at different locations can be scanned by powering the data lines connected with the pixels using the different data line signal output circuits.

1. A drive circuit of a display panel comprising a plurality of pixels arranged in a matrix, j select circuits and j data line signal output circuits, and j being an integer greater than or equal to 2;
each data line on the display panel is connected with an associated select circuit, different data lines on the display panel are connected with different select circuits, and each of the select circuits is connected with the j data line signal output circuits; any one of the data line signal output circuits is configured, when a pixel on the display panel is to be displayed, to generate a voltage signal from a grayscale value to be displayed at the pixel and to load the voltage signal onto a data line connected with the pixel; each of the select circuits is configured to control an associated data line connected therewith to be connected with one of the j data line signal output circuits and to control the associated data line connected therewith to be disconnected from the other ones of the j data line signal output circuits; and when a same grayscale is required, at least two of j positive grayscale voltages output by the j data line signal output circuits are different, and negative grayscale voltages output by data line signal output circuits outputting different positive grayscale voltages are also different.
