Problems solved by technology

[0003] The display panel generally includes multiple pressure sensors, but the pressure detection signals output by the two sensing signal output terminals of each pressure sensor will be interfered by environmental noise, which greatly reduces the accuracy of the output pressure detection signals and reduces the pressure. The signal-to-noise ratio of the detection signal affects the accuracy of the pressure detection of the display panel

Abstract

The invention discloses a display panel and a pressure detection method thereof, and a display device. The display panel comprises multiple pressure sensors, the opposite position of a first power source signal input end of a first pressure sensing unit of the pressure sensors and the first pressure sensing unit is identical to the opposite position of a first power source signal input end of a second pressure sensing unit and the second pressure sensing unit; when the first pressure sensing unit works, input signal difference of first and second power source signal input ends is V1, output signal difference of first and second sensing signal output ends is U1; when the second pressure sensing unit works, input signal difference of the first and second power source signal input ends is V2,output signal difference of the first and second sensing signal output ends is U2; the V1 and the V2 are identical in magnitude and are opposite in polarity; a pressure detection value is determinedby the pressure sensors according to difference of the U1 and the U2. The method is advantaged in that influence of environment noise on pressure detection is eliminated.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a pressure detection method thereof, and a display device. Background technique [0002] At present, as an information input tool, a display panel with a touch function is widely used in various electronic devices, for example, information inquiry machines in halls of public places, computers and mobile phones used by users in daily life and work. In this way, users only need to touch the logo on the touch screen with their fingers to operate the electronic device, which eliminates the user's dependence on other input devices, such as keyboards and mice, and makes human-computer interaction more direct and convenient. . In order to better meet the needs of users, a pressure sensor is usually installed in the touch screen to detect the touch pressure of the user when touching the touch screen. The pressure sensor can not only collect t...
