Problems solved by technology

However, due to the influence of the wiring load, the higher the power signal is transmitted, the greater the attenuation of the power signal will be, which will weaken the driving ability of the power signal to the pressure sensor 3' arranged on the top, affecting the pressure sensor 3' detection of pressure

Abstract

Embodiments of the present invention provide a display panel and a display device, which relate to the field of display technology and are used to reduce the attenuation of a power signal and effectively improve the difference in drive capability of the power signal to pressure sensing units at different positions. The display panel includes M pressure sensing unit groups, a first signal line, a second signal line and at least one first connection signal line; the pressure sensing unit group includes a first pressure sensing unit and a second pressure sensing unit; A pressure sensing unit is set in the first non-display area, a second pressure sensing unit is set in the second non-display area; the first signal line is set in the first non-display area, the first signal line and the first pressure sensor The unit is electrically connected; the second signal line is arranged in the second non-display area, and the second signal line is electrically connected to the second pressure sensing unit; the first connection signal line is arranged between the first signal line and the second signal line, The first connection signal line is electrically connected to the first signal line and the second signal line. The above-mentioned display panel is used to realize 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] At present, in order to realize the pressure sensing function of the display panel, a pressure sensor for sensing pressure is generally provided in 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 non-display areas 2' located on both sides of the display area 1', and a plurality of pressure sensors 3' are arranged in the non-display area 2' , the power terminals of each pressure sensor 3' are connected to a power line 4'. [0003] In the prior art, multiple pressure sensors 3' are usually driven simultaneously by simultaneously transmitting power signals on two power lines 4'. However, due to the influence of the wiring load, the higher the power signal is transmitted, ...
