Problems solved by technology

[0004] Due to the complex structure of the display panel, it includes many film layers. When pressed, the film layer will undergo elastic deformation and inelastic deformation. Among them, the inelastic deformation will remain in the film layer and cannot be recovered, resulting in stress accumulation in the display panel. , resulting in that when there is no stress at the position of the pressure sensor, the pressure sensor still has a certain deformation, which causes the baseline of the pressure sensor to drift and affects the accuracy of the pressure sensor to detect pressure

Abstract

An embodiment of the present invention provides a display device, which relates to the field of display technology. The display device provided by the embodiment of the present invention includes a display panel, the display panel is divided into a display area and a peripheral area surrounding the display area, and a plurality of pressure sensors are arranged in the peripheral area; the display device also includes at least one a vibrating device, the vibrating device is used to vibrate the display panel to release the stress accumulation in the display panel. The technical solution of the invention can improve the pressure detection accuracy of the pressure sensor.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] Display panels with touch functions are widely used in various display devices such as mobile phones, tablet computers, and information inquiry machines in public halls. The user can operate the display device only by pressing the logo on the display panel with a finger, which eliminates the user's dependence on other input devices (such as a keyboard and mouse) and makes human-computer interaction easier. [0003] In order to better meet the needs of users, the display panel is usually equipped with a pressure sensor for detecting the pressure of the user pressing the display panel, so that the display panel can not only collect touch position information, but also can collect pressure to enrich touch technology. scope of application. [0004] Due to the complex structure of the display panel, it includes many film layer...
