Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate and at least one pressure sensor set formed on the substrate, wherein in the same pressure sensorset, a first induction signal measurement end of a first pressure sensor and a first induction signal measurement end of a second pressure sensor are electrically connected with different input ends of a first-class summator; a second induction signal measurement end of the first pressure sensor and a second induction signal measurement end of the second pressure sensor are electrically connectedwith different input ends of a second-class summator; and the output end of the first-class summator and the output end of the second-class summator are used for outputting pressure induction detection signals of the pressure sensor set. Through the display panel in the embodiment, the effects that the pressure induction detection signals output by the pressure sensors are increased, and the pressure induction detection performance of the display panel is improved are achieved.

Description

technical field [0001] Embodiments of the present invention relate to touch display technology, and in particular, to a display panel and a display device. Background technique [0002] At present, display panels are widely used in electronic devices such as mobile phones, tablet computers, and information inquiry machines in halls of public places. 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 keyboard and mouse) 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 usually provided in the display panel, so as to enrich the application range of the touch technology. However, in the existing display panel, since the pressure detection signal output by the pressure sensor is too small, it is e...
