Problems solved by technology

Use the scanning line to turn on the thin-film transistor in the pixel, and then provide data signals to each pixel in the row through the data line in turn. In the process of charging the pixel, the scanning signal provided on the scanning line will cause charging delay due to excessive load, affecting Pixel display effect

Abstract

The embodiment of the invention discloses an array substrate, a display panel, a display device and a driving method. The array substrate includes: a plurality of pixel circuit rows, each pixel circuit row including a plurality of pixel circuits; a plurality of scanning line group, each pixel circuit row comprising at least two pixel circuit groups, each scanning line group comprising at least twoscanning lines, the at least two pixel circuit groups and the at least two scanning lines in the corresponding scanning line groups being arranged in a one-to-one correspondence mode, and the pixel circuits in the same pixel circuit group being connected with the same scanning line. Different scanning line groups provide scanning signals for each pixel circuit row in sequence, and the scanning lines in the same scanning line group provide scanning signals for the pixel circuits in the corresponding pixel circuit rows at the same time. According to the embodiment of the invention, the problemof charging delay caused by excessive load of the existing display panel is solved. Each row of pixel circuits can be ensured to have sufficient charging duration, the pixel circuits can be opened accurately and timely, and the pixel charging delay is avoided.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to an array substrate, a display panel, a display device, and a driving method. Background technique [0002] With the continuous development of display technology, display devices such as liquid crystal panels and monitors are constantly developing in the direction of thinner and lighter, larger screen, lower power consumption and higher definition. [0003] For display panels with larger and larger sizes and higher resolutions, the number of pixels that need to be connected to the same row on each scanning line becomes larger. Use the scanning line to turn on the thin-film transistor in the pixel, and then provide data signals to each pixel in the row through the data line in turn. In the process of charging the pixel, the scanning signal provided on the scanning line will cause charging delay due to excessive load, affecting Pixel display effect. ...
