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

The invention discloses an array substrate, a display device and a driving method of the display device. Grid line extension lines, data lien extension lines and a control circuit are arranged on the periphery of the array substrate. The control circuit is used for controlling grid lines and the grid line extension lines to be connected and data lines and the data line extension lines to be connected when one frame of image is displayed, and controlling the grid lines and the grid line extension lines to be disconnected and the data lines and the data line extension lines to be disconnected, and controlling two adjacent rows of grid line extension lines to have potential difference and two adjacent rows of data line extension lines to have potential difference in the time period when two adjacent frames of images are displayed. Through the control of the control circuit, voltage potential exists between two adjacent rows of grid line extension lines and between two adjacent rows of data line extension lines so that positive and negative charged ions on the periphery of the array substrate can be absorbed, and then the problem that residual images exist on the periphery of the display device is effectively solved and the display quality of the display device is improved.

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 (LCD for short), maintains one image for a long time, due to the influence of the electric field for a long time, after switching to another image, afterimages will appear on the image. The main cause of afterimages is that some charged ions will be introduced i...
