Abstract

An embodiment of the invention discloses a display panel, a display panel pressure detection method and a display device. The display panel comprises a pressure detection unit, a plurality of groups of switches and a control circuit. The pressure detection unit comprises a semiconductor film, and each group of connection ends of the semiconductor film include a first end and a second end, whereina connection line of the first end and the second line penetrates the axis of the semiconductor film. Each first end of the semiconductor film is coupled with a first detection end through a corresponding switch, and each second end is coupled with a second detection end through a corresponding switch. The control circuit is used for controlling simultaneous on or off of each group of switches corresponding to any group of the connection ends of the semiconductor film in a pressure detection stage and further used for controlling simultaneous on or off of two groups of switches corresponding to any two groups of the connection ends of the semiconductor film. By the display panel, the display panel pressure detection method and the display device, the problem of pressure detection result inaccuracy of a pressure sensor due to non-detection zones in the prior art is solved.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display panel, a pressure detection method thereof, and a display device. Background technique [0002] With the rapid development of portable electronic terminal equipment, especially mobile phone and tablet technology, more and more new technologies are applied to these electronic terminal equipment. Pressure-sensing touch technology is a new technology that has received widespread attention in the field. The display with integrated pressure-sensitive touch technology can clearly distinguish the difference between a touch and a press. [0003] When the user presses the screen, the display integrated with the pressure sensor can accurately recognize the pressure conveyed by the user on the touch surface, and then realize different operations, such as calling up more control options in applications such as information, music and calendar. Existing pressure sen...
