Abstract

An array substrate, a display panel and a display device are disclosed. The array substrate includes a base substrate, and a bias voltage applying circuit and a plurality of semiconductor pressure sensors both disposed at a side of the base substrate. The bias voltage applying circuit is electrically connected to a first power supply signal inputting terminal and a second power supply signal inputting terminal of the semiconductor pressure sensor via a first power supply signal line and a second power supply signal line, respectively, to supply a bias voltage to the semiconductor pressure sensor. A concentration of the dopant ions is higher when the related semiconductor pressure sensor is closer to the bias voltage applying circuit, so that an electrical resistance value of said semiconductor pressure sensor is lower.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of semiconductors, and in particular, to an array 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 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 bri...
