Abstract

Embodiments of the present invention provide a display panel, a driving method thereof, and a display device, which relate to the field of display technology and can solve the problem of insignificant drive power consumption reduction and screen flicker when different frequencies are used to drive static images and dynamic images in the prior art. The problem. The display panel includes gate lines, data lines, pixel units, additional signal lines, driving sources and pixel driving circuits. The driving source determines whether each pixel unit is a dynamic pixel or a static pixel before a frame is displayed. The static pixel includes the first static pixel and the second static pixel, and drives the first static pixel with the first frequency, and drives the dynamic pixel with the second frequency. pixel, driving the second static pixel with a third frequency. The pixel driving circuit is turned on and charges the pixel unit. There is a preset distance between the dynamic pixel and the first static pixel, and the third frequency is higher than the first frequency and lower than the second frequency.

Description

technical field [0001] The present 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] TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor Liquid Crystal Display), as a flat panel display device, has become more and more popular due to its small size, low power consumption, no radiation and relatively low production cost. It is widely used in the field of high-performance display. [0003] The array substrate of the TFT-LCD includes a plurality of gate lines and data lines intersecting horizontally and vertically, and a plurality of pixel units arranged in a matrix form are defined by intersections of the gate lines and data lines. In the process of displaying a frame of picture, generally, a driving signal with a certain frequency such as 60 Hz can be used to scan the gate line from top to bottom row by row, so that the above pixel units ...
