Embodiment Construction

[0057] The specific implementation manners of the array substrate, the display device and the driving method thereof provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0058] Wherein, the size and shape of each structure in the drawings do not reflect the real proportion of the array substrate, and the purpose is only to illustrate the content of the present invention. The source and drain of the switching thin film transistor used in all embodiments of the present invention are symmetrical, so the source and drain can be interchanged. In the embodiment of the present invention, in order to distinguish the two poles of the transistor except the gate, one pole is called the source, and the other pole is called the drain.

[0059] It is to be understood that when an element A is "connected" to an element B, it may mean that A is directly connected to B, or that intervening elements between A and B...

Abstract

An array substrate, a display device and a driving method thereof. Gate-line extension lines, data-line extension lines and a control circuit are disposed in a peripheral area of the array substrate. The control circuit is configured to connect the gate lines to the gate-line extension lines and connect the data lines to the data-line extension lines in a time period of displaying an image, and configured to disconnect the gate lines from the gate-line extension lines, disconnect the data lines from the data-line extension lines, control at least part of the gate-line extension lines to have potential difference, and control at least part of the data-line extension lines to have potential difference in a time period between displaying two adjacent images.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate, a display device and a driving method thereof. Background technique [0002] At present, display technologies are widely used in displaying televisions, mobile phones, and public information, and display devices for displaying images are also various, and can display rich and colorful images. With the rapid development of flat panel display technology, the demand for image quality of display devices is getting higher and higher. [0003] As an important content of picture quality evaluation, afterimage has been widely concerned for a long time. When a display device, such as a liquid crystal display panel (LCD for short), keeps displaying one picture for a long time, due to the influence of the electric field for a long time, after switching to another picture, afterimages will appear on the picture. The main cause of afterimages is that some charged ions w...
