Abstract

The invention discloses a driving device which comprises multiple cascaded shifting registers, multiple detection switches and multiple detection ends. The control ends of the detection switches are electrically connected with the shifting registers respectively. The first poles of the detection switches are electrically connected with the signal output ends of the shifting registers respectively. The second poles of the detection switches at least spaced by a level are electrically connected and jointly connected to the same detection end. Each detection end sequentially receives data signals of the shifting registers. Due to the fact that each detection end sequentially receives data signals of the shifting registers, the position of the abnormal shifting register can be directly, rapidly and accurately acquired, and an effective solution is provided for analysis of abnormality of a liquid crystal display panel.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular to a driving device, an array substrate and a display device. Background technique

[0002] Liquid crystal displays (liquid crystal displays, LCDs) or organic light-emitting diodes (Organic Light-Emitting Diodes, OLEDs) have the advantages of low radiation, small size, and low energy consumption, and have gradually replaced traditional cathode ray tube displays (Cathode ray tubes) in some applications. Ray Tube display, CRT), and thus are widely used in information products such as notebook computers, personal digital assistants (Personal Digital Assistant, PDA), flat-screen TVs, or mobile phones. The traditional method of liquid crystal display is to use an external driver chip to drive the chips on the panel to display images, but in order to reduce the number of components and reduce manufacturing costs, it has gradually developed in recent years to make the driver circu...
