Problems solved by technology

In practice, if a certain signal output line is broken, the broken signal output line will not be able to transmit the pressure detection signal to the driver chip, and the pressure sensor connected to the broken signal output line will not be able to complete the pressure detection. , that is, the pressure sensor fails
Undoubtedly, this will affect the pressure sensing performance of the display panel

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0033] As mentioned in the background technology, the existing display panel is often equipped with a plurality of signal output lines, one end of which is connected to the pressure sensor, and the other end is connected to the driver chip, and is used to transmit the pressure detection signal output by the pressure sensor. to the driving chip, so that the driving chip determines the magnitude of the touch pressure based on the pressure detection signal. In practice, if a certain signal output line is broken, the ...

Abstract

The embodiment of the invention discloses a display panel, a display device and a driving method for the display panel. The display panel comprises a plurality of pressure sensors, a plurality of first signal output wires, a plurality of second signal output wires and at least one standby output wire, wherein each pressure sensor has a first sensing signal measuring end and a second sensing signal measuring end; the first sensing signal measuring end of each pressure sensor is electrically connected with each corresponding first signal output wire; the second sensing signal measuring end of each pressure sensor is electrically connected with each corresponding second signal output wire; the standby output wire is electrically connected with the first sensing signal measuring end or the second sensing signal measuring end of at least one pressure sensor. The display panel provided by the invention is capable of reducing the possibility of losing efficacy under the effect of disconnection of the pressure sensor and the connected signal output wire and is capable of promoting the pressure detection property of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to pressure detection technology, and in particular, to a display panel, a display device, and a driving method for the display panel. Background technique [0002] At present, display panels are widely used in electronic devices such as mobile phones, tablet computers, smart wearable devices, and information inquiry machines in public halls. In this way, the user can operate the electronic device only by touching the mark on the electronic device with a finger, which eliminates the user's dependence on other input devices (such as a keyboard and a mouse, etc.), and makes human-computer interaction easier. [0003] In order to better meet user needs, a pressure sensor for detecting the amount of touch pressure when the user touches the display panel is generally provided in the display panel, so as to enrich the application range of the touch technology. Existing display panels are often provided with a plur...
