Abstract

The invention provides a display panel and a display device, and relates to the technical field of display, which is used to reduce the difficulty of pressure detection. A display area of the displaypanel has a plurality of gate lines and a plurality of data lines; the gate lines and the data lines intersect to define a plurality of display pixels and a plurality of dummy pixels; the plurality ofdisplay pixels are arranged in a matrix in the display area, and the dummy pixels are located on a side of the display pixels adjacent to a non-display area; each dummy pixel includes a dummy pixel electrode, a dummy common electrode, and a dummy thin film transistor, wherein projections of the dummy pixel electrode and the dummy common electrode on the plane where the display panel is located overlaps, a control electrode of the dummy thin film transistor is connected to the gate line, a first electrode of the dummy thin film transistor is connected to the data line, and a second electrode of the dummy thin film transistor is connected to the dummy pixel electrode. Pressure sensing units are disposed in the non-display area, and first output ends of the pressure sensing units are connected to the dummy pixel electrodes. The above display panel is used to implement screen display.

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] With the development of touch display technology, in order to better meet the needs of users, in addition to the traditional touch technology capable of detecting a touch position, a pressure touch technology capable of detecting a touch pressure has emerged. The pressure touch technology generally requires a pressure sensing unit to be disposed in the display panel. When the display panel is under pressure, the pressure sensing unit will output a voltage signal, and the pressure when the user touches the display panel can be obtained by detecting the voltage signal. However, because the current driver chip IC is not configured with a port for reading voltage signals, the difficulty of pressure detection increases. 【Content of invention】 [0003] In view of this, the present invention provides a ...
