More Information
Summary: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.
