A display panel, its driving method and display device

Abstract

The invention discloses a display panel, its driving method and a display device. When each row of sub-pixels of the display panel is displaying, when the data signals corresponding to the row of sub-pixels are not all common voltage signals, the source driving circuit sends Each output terminal outputs a data signal, and the source control circuit provides the data signal output by each output terminal to the corresponding data line; when the data signals corresponding to the sub-pixels in this row are all common voltage signals, the data output by the source drive circuit to each output terminal The voltage amplitude of the signal is the same as the voltage amplitude of the data signal output from the previous row of sub-pixels to each output terminal when displaying, and the source control circuit provides a common voltage signal to each data line. In this way, when the data signals corresponding to a row of sub-pixels are all common voltage signals, the signal on the data line is provided by the source control circuit, thereby avoiding frequent jumps in the voltage amplitude of the data signal output by the source drive circuit to the same data line , to reduce the power consumption of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a driving method thereof and a display device. Background technique [0002] With the development of science and technology, the resolution of display screens such as mobile phones has reached the current 1920*1080 from 240*320, or even higher. The higher the resolution of the display screen, the more delicate the displayed picture, and the better the visual experience brought. [0003] At present, some high-resolution LCD screens use such as figure 1 The triple gate structure is shown, but when the structure displays some solid-color pictures, take the red picture as an example, such as figure 2 As shown, the data line datan( figure 2 Take data2 as an example to illustrate) the voltage amplitude of the signal on the signal will jump frequently, resulting in increased power consumption during display. Contents of the invention [0004] In view of this, e...
