Display panel and display device

Abstract

The invention provides a display panel and a display device. The display panel comprises a display region and a non-display region surrounding the display region. The non-display region on a substrate is provided with a plurality of pressure sensors and a drive circuit. Each pressure sensor comprises a first input end, a second input end, a first output end and a second output end which are electrically connected with the drive circuit through a first power signal line, a second power signal line, a first induction signal line and a second induction signal line respectively; at least one of the first power signal line, the second power signal line, the first induction signal line and the second induction signal line comprises a first sub-signal connecting line and a second sub-signal connecting line which are electrically connected; according to any two pressure sensors, the differences between the sums of the resistances of the first sub-signal connecting lines and the second sub-signal connecting lines which are electrically connected is smaller than a first preset value, and the pressure detection sensitivity of the pressure sensors is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] The pressure-sensing technology is to add a pressure-sensing device on the display screen. Touching the display screen with a finger and pressing it again will bring different interactive effects. That is to say, the screen can feel different strengths such as light touch, normal touch and heavy pressure, and more three-dimensional feeling of finger operation, which can realize more diverse operation methods. [0003] In the existing pressure-sensitive display panel, the pressure-sensitive touch unit is generally arranged in the non-display area of ​​the display panel, so as to prevent the pressure-sensitive touch unit from affecting the normal display of the display area. At present, the aspect ratio of display devices such as mobile phones is getting larger and larger. Since the distances between the ...

AI Technical Summary

Problems solved by technology

At present, the aspect ratio of display devices such as mobile phones is getting larger and larger. Since the distances between the non-display pressure sensors and the driving circuit are different, each pressure sensor is electrically connected to the driving circuit at the bottom of the display panel through the signal line, so The lengths of the signal lines connected to each pressure sensor are different, resulting in a difference in the signal transmission pressure drop of the pressure sensor. The pressure detection sensitivity of the pressure sensor near the drive circuit and the pressure sensor far away from the drive circuit are inconsistent, which affects the accuracy of pressure detection.
