Problems solved by technology
[0003] Since the grounding wire 4' is set close to the edge of the display panel, static charges can easily enter the display panel through the grounding wire 4'. The line 4' flows into the pressure sensor 3', because the signal potential provided by the power line 5' is high, the static charge cannot flow out from the power line 5', therefore, the static charge will flow into the pressure sensor 3', thereby affecting the pressure sensor 3' cause damage and affect the pressure detection performance of the display panel

An embodiment of the invention provides a display panel and a display device and relates to the technical field display. The display panel is used for increasing the guide paths of electrostatic charge and enhancing the protecting ability of pressure sensing units to the electrostatic charge. The display panel comprises a plurality of display pixels and a plurality of virtual pixels and is characterized in that each display pixel comprises a first thin film transistor, and the first poles of each row of first thin film transistors are connected with one display data line; at least part of thevirtual pixels comprise second thin film transistors, and the first poles of the second thin film transistors are connected with a virtual data line. The display panel further comprises a plurality ofpressure sensing units, the first input end of each pressure sensing unit is connected with a grounding signal line, and the first input end of each pressure unit is further connected with the virtual data line; the grounding signal line is arranged in a non-display area and connected with the virtual data line through a first connecting signal line. The display panel is used for displaying images.
Description
【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] In order to realize the pressure sensing function of the display panel, a pressure sensor for sensing pressure is generally arranged in the 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 first input terminal IN1' of each pressure sensor 3' is connected to the ground line 4', and the second input terminal IN2' of each pressure sensor 3' is connected to the power line 5'. Wherein, the ground wire 4' is located on the side of the pressure sensor 3' away from the display area 1' in the non-display area 2'. [0003] Since the grounding wire 4' is...
