Abstract

The invention discloses a display panel and a driving method thereof and a display device. One specific embodiment of the display panel comprises N strip-shaped electrodes, m test signal input lines, n test signal output lines, a switch unit and a drive circuit, wherein m, n and N are positive integers, and the drive circuit is used for providing control signals for the switch unit, providing test input signals for the test signal input lines, receiving test output signals output by the test signal output lines and judging whether strip-shaped electrodes with abnormal connection states exist in a to-be-tested electrode set or not according to the test input signals and the test output signals. By means of the embodiment, abnormal state detection of the strip-shaped electrodes in the display panel can be achieved, therefore, the sensitivity of touch detection is improved, and normal use of the touch function is guaranteed.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a driving method thereof, and a display device. Background technique [0002] Capacitive touch screens can be divided into surface capacitive touch screens and projected touch screens according to their touch principles. The projected touch screen can be further divided into a self-capacitive touch screen and a mutual-capacitive touch screen. [0003] In a mutual capacitive touch screen, usually a plurality of strip-shaped touch transmitting electrodes are arranged on one side of the array substrate, and strip-shaped touch receiving electrodes vertically intersecting with the touch transmitting electrodes in space are arranged on the side of the color filter substrate. During touch detection, pulse detection signals are sequentially provided to the touch transmitting electrodes, the touch receiving electrodes receive touch sensing signals, and the tou...
