Abstract

The invention discloses an array substrate, a display abnormality determining method therefor, a display panel, and a display device, is used for timely finding a display abnormality of an array substrate through the array substrate provided by the invention, and further avoiding the impact on a display effect. The array substrate comprises a source drive chip which is disposed in a frame region of the array substrate and comprises a resetting pin and a plurality of unoccupied output pins; a resetting unit which is disposed in the frame region of the array substrate and comprises an output endand a plurality of input ends, wherein the input ends of the resetting unit are electrically connected with the unoccupied output pins in a one-to-one manner, and the output end of the resetting unitis electrically connected with the resetting pin of the source drive chip. The resetting unit is used for judging whether the display of the array substrate is abnormal or not according to a first preset threshold value, a reference electric signal and the voltage signals outputted by the plurality of unoccupied output pins, and resetting the source drive chip when the display is abnormal.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a method for determining abnormal display thereof, a display panel and a display device. Background technique [0002] During the normal working process of the display screen, the source driver chip (Source IC) will provide the display signal corresponding to each data line according to the working mode of the display screen, so as to ensure that each pixel unit in the display screen can receive the signal corresponding to the pixel unit. The display signal provided by the data line to achieve normal display. However, due to the damage of the Source IC or other reasons, the display signal provided by the Source IC is abnormal, so that the display signal provided by each data line is disordered, etc., so that the display panel shows an abnormal display phenomenon, thereby affecting the display effect. Contents of the invention [0003] In view of...
