Abstract

The present invention discloses a display panel and a drive method thereof, and a display device. A plurality of crack detection points are arranged on a crack detection line, equivalently, a non-display area is divided into a plurality of areas, in an electricity test phase, each detection switch is controlled to be conducted, signals loaded on each data line are detected to determine whether there are cracks between the detection points or not; if no, uniform bright images or dark images are displayed, if yes, an open circuit is generated between the cracks and the detection points, the signals transmitted from the crack detection line cannot be transmitted to the data lines corresponding to the detection points to cause that the data lines corresponding to other detection points in thedirection of transmission of signals of the detection point are in a suspension state, there is brightness difference between the images of pixel rows corresponding to the data lines and the images displayed when there is no crack, in an IC binding phase, it is determined whether there is a crack or not through a resistance value on the crack detection line is detected, if the resistance value onthe crack detection line is infinite, it shows that there are cracks.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof and a display device. Background technique [0002] With the rapid development of active-matrix organic light-emitting diodes (Active-matrix Organic Light Emitting Display, AMOLED) in the display field, the improvement of yield rate is imminent. Since the AMOLED substrate is a material with good flexibility, tiny cracks are prone to occur at the edge of the flexible panel. We know that the flexible display uses the organic light-emitting diode technology, and water and oxygen will cause destructive chemical reactions to the organic light-emitting diode. reaction, and the existence of cracks provides a way for water and oxygen, which eventually leads to dark spots in the light-emitting area, and even leads to a series of problems such as material failure and life reduction. There are some crack detection methods in the prior art,...
