Abstract

An embodiment of the invention provides a display panel and its driving method, a display device, and relates to the technical field of display. The display panel is used for solving attenuation of apower signal. A non-display zone of the display panel is provided with multiple cascaded shift register units and multiple pressure sensing units; each shift register unit comprises a shift input endand a shift output end, wherein the shift output end of a previous shift register unit in adjacent two shift register units is connected to the shift input end of a later shift register unit; every pressure sensing unit comprises a first input end and a second input end; the first input end and the second input end are connected to the shift output ends of different shift register units, wherein afirst buffer unit is connected to the middle of the first input end of the pressure sensing unit and the shift output end connected with it; a second buffer unit is connected to the middle of the second input end of the pressure sensing unit and the shift output end connected with it. The display panel is used for displaying an image.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof, and a display device. 【Background technique】 [0002] At present, in order to realize the pressure sensing function of the display panel, a pressure sensor for sensing pressure is generally arranged in a non-display area of ​​the display panel. Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a display panel in the prior art. The display panel includes a display area 1' and a non-display area 2', and a plurality of pressure sensors 3' are arranged in the non-display area 2'. The ground terminals of each pressure sensor 3' are connected to a ground signal line 4', and the power terminals of each pressure sensor 3' are connected to a power signal line 5'. However, when the power signal line 5' transmits the power signal to each pressure sensor 3', the phenomenon of attenuation of the power signal wi...
