Abstract

Embodiments of the invention disclose a display substrate, a display panel and a display device. The display substrate comprises a display area and a non-display area surrounding the display area. The display substrate further comprises a first flexible substrate, a plurality of pressure sensors that are arranged on the first flexible substrate and are in the display area, and a second flexible substrate that is arranged at one side, far from the first flexible substrate, of the pressure sensors, wherein the second flexible substrate covers the pressure sensors. Through adoption of the above technical solution, the pressure sensors are arranged in the display area, so that when the display area is touched, the pressure sensors in the display area are ensured to deform greatly according to a touch pressure, and the pressure detection sensitivity is ensured; the second flexible substrate covers the pressure sensors, so that the pressure sensors arranged in the display area fail to affect the opening rate of the display substrate; and two layers of flexible substrate ensure high deformation, improve deformation of the pressure sensors between two layers of flexible substrates, and improve the pressure detection sensitivity.

Description

technical field

[0001] Embodiments of the present invention relate to the field of touch technology, and in particular, to a display substrate, a display panel, and a display device. Background technique

[0002] At present, more and more electronic devices are equipped with touch screens, for example, information machines in the halls of public places, computers and mobile phones used by users in daily life and work. In this way, the user can operate the electronic device only by touching the sign on the touch screen with a finger, which eliminates keyboard and mouse operations, and makes human-computer interaction more straightforward. In order to better meet user requirements, a pressure sensor for detecting the magnitude of the touch pressure when the user touches the touch display screen is usually provided in the touch display screen.

[0003] The bridge-type strain sensor is a pressure sensor that can detect the magnitude of the touch pressure. The bridge-type strain...
