Abstract

The invention discloses a display panel, a touch positioning method thereof and a display device, and belongs to the technical field of display, the display panel comprises a display area and a frame area comprising an FPR processing module and an FPR driving circuit; the display area comprises a plurality of scanning subareas arranged in the first direction, and a plurality of power lines which are arranged in the second direction and extend in the first direction are arranged in the display area; each scanning subarea is divided into m touch control detection areas by a plurality of power lines; and each power line corresponds to n touch detection areas. The method comprises the steps that an FPR driving circuit sequentially sends an initial signal to each scanning subarea so as to control a touch detection area in each scanning subarea to conduct touch scanning according to the initial signal; and each power line obtains a touch detection signal of the corresponding touch detection area, so that the FPR processing module positions a touch position according to all the touch detection signals. The display panel can solve the problem that an existing display panel applying the FPR technology is low in aperture ratio and penetration rate.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel, a touch positioning method thereof, and a display device. Background technique [0002] With the development of display technology, multi-functional display panels have gradually attracted the attention of terminal manufacturers. Among them, the panel equipment that uses FPR (Fingerprint Recognition, fingerprint identification) technology is particularly prominent. In devices using FPR technology, the fingerprint recognition FPR circuit, touch control circuit and display circuit are usually integrated into the panel at the same time, resulting in denser lines in the non-display area of ​​the panel, which in turn makes the panel aperture ratio and penetration rate low. Contents of the invention [0003] Embodiments of the present invention provide a display panel, a touch positioning method thereof, and a display device, which can solve the problem...
