Display panel, driving method thereof and display device

Abstract

The invention discloses a display panel, a driving method thereof and a display device, and relates to the technical field of display. The display panel comprises a plurality of pixel rows and a plurality of pixel columns, wherein sub-pixels in the pixel rows are arranged along a first direction, and sub-pixels in the pixel columns are arranged along a second direction; a plurality of data lines,wherein the same data line is electrically connected with at least part of sub-pixels in two adjacent pixel columns; a plurality of switch units, wherein the first poles of the switch units are electrically connected with the data lines in a one-to-one correspondence manner; data signal ends arranged in the first direction, wherein one data signal end is electrically connected with the second poles of the N switch units, and N is larger than or equal to 2; N switch control lines, wherein the control ends of the N switch units corresponding to the same data signal end are respectively connectedto different switch control lines, and in any pixel row, the colors and polarities of the sub-pixels electrically connected with the data lines corresponding to the same data signal end are the same.Therefore, the power consumption of the display panel is saved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a driving method thereof, and a display device. Background technique [0002] Liquid crystal display is a flat and ultra-thin display device, which consists of a certain number of color or black and white pixels, placed in front of the light source or reflective surface. Liquid crystal displays consume very little power, making them favored by engineers for electronic devices that run on batteries. Its main principle is to stimulate liquid crystal molecules with current to generate points, lines, and surfaces to form a picture with the back lamp tube. [0003] Generally, a liquid crystal display is provided with several sub-pixels, the sub-pixels form sub-pixel rows and sub-pixel columns, each sub-pixel row includes a plurality of pixel units, and each pixel unit usually includes red sub-pixels, green sub-pixels and blue sub-pixels. In order t...

Problems solved by technology

When the monitor displays a specific picture, such as a solid-color picture, take the red picture as an example, because in one pixel row, the data line corresponding to the same data signal terminal is connected to the red sub-pixel, and the blue and green sub-pixels. pixel, therefore, the data that the data signal end needs to provide to the red sub-pixel is 255. When scanning the blue sub-pixel or green sub-pixel in the same row, the data signal end needs to provide The data is 0. Therefore, when scanning the same pixel row, the data signal sent by the same data signal terminal needs to flip / jump multiple times, which will greatly increase the power consumption of the LCD display, which is not conducive to saving power consumption.
