Abstract

The invention discloses a display panel and a display device. The display panel comprises at least one pressure sensor, a first substrate and a second substrate; the first substrate is provided with aplurality of supporting spacers; the second substrate is opposite to the first substrate, the second substrate is provided with a plurality of bulges, the bulges are in contact with the supporting spacers in a one-to-one corresponding mode, the surface, close to the corresponding supporting spacer, of each bulge is a first contact surface, the second substrate also includes a non-bulge area around the bulges, and the roughness of the first contact surfaces is greater than that of the surface of the non-bulge area. According to the technical scheme, the frictional force between the supportingspacers and opposite side substrates is increased, and therefore the problem of baseline drift when the pressure sensors are used for pressure detection is solved.

Description

technical field [0001] Embodiments of the present invention relate to pressure touch technology, and in particular, to a display panel and a display device. Background technique [0002] At present, display panels integrated with touch electrodes are widely used in electronic devices such as mobile phones, tablet computers, and information inquiry machines in halls of public places. In this way, the user can operate the electronic device only by touching the mark on the electronic device with a finger, which eliminates the user's dependence on other input devices (such as keyboard and mouse) and makes human-computer interaction easier. [0003] In order to better meet user needs, a pressure sensor for detecting the amount of touch pressure when the user touches the display panel is usually provided in the display panel, so as to enrich the application range of the touch technology. The liquid crystal display panel in the prior art is provided with a support spacer to mainta...
