A display panel, testing method thereof, and display device

Abstract

The embodiment of the invention discloses a display panel and a test method thereof and a display device. The display panel comprises multiple pressure detection units, multiple first switches and multiple second switches. The first input end of each pressure detection unit is electrically connected with a first input detection point through each first switch, and the second input end of each pressure detection unit is electrically connected with a second input detection point through each first switch. The first output end of one pressure detection unit is electrically connected with a firstoutput detection point, the second output end of another pressure detection unit is electrically connected with a second output detection point, and multiple pressure detection units are connected inseries through multiple second switches. Or the first output ends of multiple pressure detection units are electrically connected with the first output detection point through multiple second switches, and the second output ends of multiple pressure detection units are electrically connected with the second output detection point through multiple second switches. According to the display panel, the poor state which cannot be detected by the present test framework can be detected so that misjudgment can be avoided.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a display panel, a testing method thereof, and a display device. Background technique [0002] With the rapid development of portable electronic terminal equipment, especially mobile phone and tablet technology, more and more new technologies are applied to these electronic terminal equipment. Pressure-sensing touch technology is a new technology that has received widespread attention in the field. The display with integrated pressure-sensitive touch technology can clearly distinguish the difference between a touch and a press. [0003] When the user presses the screen, the display integrated with the pressure sensor can accurately recognize the pressure conveyed by the user on the touch surface, and then realize different operations, such as calling up more control options in applications such as information, music and calendar. Existing pressure sensors are gen...

Problems solved by technology

However, if there is a short circuit or open circuit between the input terminal and the output terminal of the pressure sensor, the existing pressure sensitivity test system cannot detect the defect, resulting in a misjudgment
