Embodiment Construction

[0072] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0073] With the development of display technology, display devices with low power consumption are favored. When driving the display panel in the display device to display, each sub-pixel in the display panel needs to be charged, and the more the charging amount of each sub-pixel, the greater the power consumption required to drive the display panel to display images. The embodiment of the present application provides a method for driving a display panel, which can reduce the total charging amount of each sub-pixel in the display panel when driving the display panel to display images, thereby reducing the power consumption required for driving the display panel to display images.

Abstract

The invention discloses a driving method and device of a display panel and a display device, and belongs to the technical field of display. The method comprises the steps that after the ith row of sub-pixels in the display panel are scanned, the reference gray scale of each sub-pixel in the jth row of sub-pixels is determined in each connection mode of multiple data lines, the ith row of sub-pixels and the jth row of sub-pixels are two rows of sub-pixels sequentially scanned in the display panel, i is larger than or equal to 1, and j is larger than or equal to 1; a target connection mode enabling the gray scale change degree of the jth row of sub-pixels to be minimum is determined in the multiple connection modes of the multiple data lines; the plurality of data lines are connected according to a target connection mode; and before the jth row of sub-pixels are scanned, the plurality of data lines are disconnected. The problem that power consumption for driving the display panel to display images is large is solved. The driving method is used for driving the display panel to display images.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a method and device for driving a display panel, and a display device. Background technique [0002] With the development of display technology, display devices with low power consumption are favored. [0003] The display panel in the display device includes a plurality of sub-pixels arranged in an array, a plurality of horizontally arranged gate lines and a plurality of vertically arranged data lines, each gate line is connected to a row of sub-pixels, and each data line is connected to a column of sub-pixels. When driving the display device to display images, the gate line scans each row of sub-pixels sequentially, and when each row of sub-pixels is scanned, the potential on the data line is adjusted from the potential corresponding to the previous row of sub-pixels to the corresponding potential of the current row of sub-pixels, so as to The row of sub-pixels is ch...
