Abstract

The embodiment of the invention discloses an array substrate, a display panel, a display device and an array substrate manufacturing method. The array substrate comprises a substrate, including a display area and a non-display area surrounding the display area, and at least one pressure sensor. The display area of the substrate is provided with a plurality of pixel units including thin-film transistors. The at least one pressure sensor is located in the non-display area of the substrate, is disposed in the same layer as the active layer of the corresponding thin-film transistor and is fabricated by using the same material as the active layer. The active layer comprises a channel region and a heavily doped region. The square resistance of the pressure sensor is greater than the square resistance of the heavily doped region of the active layer. The area of the pressure sensor is reduced.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to an array substrate, a display panel, a display device, and a method for manufacturing the array substrate. Background technique [0002] At present, as an information input tool, a display panel with a touch function is widely used in various display products 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 sign on the touch display panel with his fingers, 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 touch pressure when the user touches the touch display panel is usually provided in the touch display panel, so that it can not only collect touch position information, b...
