Abstract

The invention provides a pixel driving circuit, a pixel driving method, an array substrate and a display device. The pixel driving circuit comprises a plurality of pixel areas; a pixel electrode array; at least one thin film transistor switch is arranged in each pixel area; in the same row of pixel electrodes, the polarities of voltage signals input on two adjacent pixel electrodes are opposite; the M rows of pixel electrodes are divided into Q pixel groups and comprise a first pixel group, a second pixel group and (Q-2) third pixel groups located between the first pixel group and the second pixel group, and each third pixel group comprises at least q rows of pixel electrodes; in the same column of pixel electrodes, the polarities of voltage signals input to the pixel electrodes in the same pixel group are the same, and the polarities of voltage signals input to the pixel electrodes of two adjacent pixel groups are opposite. According to the pixel driving circuit, the pixel driving method, the array substrate and the display device disclosed by the invention, real-time switching between different frame frequencies can be realized.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel driving circuit, a pixel driving method, an array substrate and a display device. Background technique [0002] In the display market, ultra-high-definition, high-refresh-rate display devices have become the technology development trend of enterprises. Especially for high-end large-size display panels, the refresh rate is gradually shifting to 120Hz. However, in general large-size display products, such as TV products, the pixel structure only supports one frame rate, such as only 60Hz or only 120Hz, and it is impossible to switch between the frame rate of 60Hz and 120Hz in real time. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a pixel driving circuit, a pixel driving method, an array substrate and a display device, capable of switching between different frame rates in real time. [0004] I...
