Abstract

The invention discloses a sensing panel, a display device and a driving method thereof. The photosensitive unit and the pressure sensing unit are simultaneously integrated on the same sensing panel, and the photosensitive unit and the pressure sensing unit are stacked so that they can share a fixed potential electrode. In this way, after the fixed potential is applied to the fixed potential electrode, the functions of pressure sensing and touch sensing can be simultaneously realized on the same sensing panel. Moreover, the sensing panel is beneficial to be integrated in the display device, and can realize high-precision pressure sensing and touch detection functions with little modification of the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a sensing panel, a display device and a driving method thereof. Background technique [0002] Pressure sensing technology refers to the technology that can detect external force. This technology has been used in industrial control, medical and other fields a long time ago. At present, the way to achieve pressure sensing in the display field, especially in the field of mobile phones or tablets, is to add an additional mechanism to the backlight part of the display panel or the middle frame of the mobile phone. changes, and the detection accuracy of this design is limited due to large assembly tolerances. [0003] Therefore, how to realize the pressure sensing with high detection accuracy with little modification of the display panel hardware is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the embodiments of th...
