The embodiment of the present invention discloses a display substrate, a display panel and a display device, wherein the display substrate includes a display area and a non-display area surrounding the display area, and the display substrate further includes: a first flexible substrate; located on the first flexible substrate and A plurality of pressure sensors located in the display area; a second flexible substrate located on the side of the pressure sensors away from the first flexible substrate, and the second flexible substrate covers the pressure sensors. With the above technical solution, a pressure sensor is set in the display area to ensure that when the display area is touched, the pressure sensor located in the display area will be deformed greatly according to the touch pressure to ensure the pressure detection sensitivity; and the pressure sensor is covered by the second flexible substrate to ensure the setting The pressure sensor in the display area will not affect the aperture ratio of the display substrate; at the same time, the two-layer flexible substrate ensures a large deformation, which increases the deformation of the pressure sensor located between the two flexible substrates and increases the pressure detection sensitivity.
Description
Technical field [0001] The 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 inquiry machines in public halls, computers and mobile phones used by users in daily work. In this way, the user can operate the electronic device only by touching the mark on the touch screen with a finger, and get rid of keyboard and mouse operations, making human-computer interaction more straightforward. In order to better meet the needs of users, a pressure sensor for detecting the magnitude of the touch pressure of the user in the process of touching the touch screen is usually provided in the touch screen. [0003] The bridge strain sensor is a pressure sensor that can detect the touch pressure. The bridge strain sensor detects the in-plane deformation caused b...
