Problems solved by technology

These high and low level switching is the main source of power consumption when the display panel is working, so the current display panel charging sequence has a lot of high and low level switching, resulting in relatively high power consumption of the display

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0024] An embodiment of the present invention provides a method for driving a display panel. The display panel includes a plurality of pixel units arranged in a matrix, and each pixel unit includes N sub-pixels, where N is a positive integer. The method includes: controlling each frame of the displayed image, every two rows of pixel units is a sub-drive cycle, the last charged sub-pixel in the previous row of pixel units is the same as the display color of the first charged sub-pixel in the next row of pixel units ...

Abstract

The invention discloses a driving method of a display panel, a multiplexer, and the display panel. The driving method comprises steps that every N frames of a display image are used to form a driving period, and every two rows of pixel units of every frame of the display image are used to form a sub-driving period. Display colors of a last-charged sub-pixel of a former row of pixel units, the last-charged sub-pixel of the next row of pixel units, the last-charged sub-pixel of the former sub-driving period, and the first-charged sub-pixel of the next sub-driving period are the same. The sub-pixel charging clock signal of the last-charged sub-pixel of the former row of pixel units can last till the completion of the charging of the first-charged sub-pixel of the next row of pixel units, and then high-level low-level switching is carried out. The sub-pixel charging clock signal of the last-charged sub-pixel of the former sub-driving period can last till the completion of the charging of the first-charged sub-pixel of the next sub-driving period, and then the high-level low-level switching is carried out. The power consumption of the display panel is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a driving method of a display panel, a multiplexer, and a display panel. Background technique [0002] Currently, display technologies are widely used in displaying televisions, mobile phones, and public information, and display panels for displaying images are also various, and can display rich and colorful images. In the process of transmitting data signals, the traditional display panel uses a multiplexer to provide data signals for each data line in time division in order to increase the transmission speed, so that the sub-pixels are charged to the required display voltage to display different gray levels. . The main function of the multiplexer is to multiplex and select a data bus using the clock signal time-sharing principle to realize charging of three columns of sub-pixels. Each row of sub-pixels is formed by repeated arrangements of combinat...
