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 addition to the traditional touch technology that can detect the position of the touch, there is also a pressure touch technology that can detect the pressure of the touch. Through the pressure touch, a more convenient man-machine can be realized Interaction, the pressure sensitive sensor is a necessary element to realize the pressure touch. The pressure sensing sensor is integrated on the display panel, and a connection line is set between the pressure sensor and the driver chip. The driver chip provides a bias voltage for the pressure sensor through the connection line, and obtains the signal output by the pressure sensor through the connection line, so as to perform pressure touch detection.

Problems solved by technology

[0003] The greater the amplitude of the output signal of the pressure sensing sensor, the better the effect of pressure detection based on the output signal. The amplitude of the output signal of the pressure sensing sensor is positively related to the absolute value of its bias voltage. Therefore, in order to increase the output of the pressure sensing sensor The signal amplitude can increase its bias voltage. However, the larger the bias voltage of the pressure-sensitive sensor, the greater the heat generation of the pressure-sensitive sensor will increase, which will cause adverse effects on the pressure touch function or display function.
