Abstract

Embodiments of the invention provide a pressure touch detection circuit and method and a display panel, relates to the technical field of display, and aims at carrying out pressure touch detection in the manufacturing process of the display panel so as to pre-judge whether pressure sensors are bad or nor and then avoid the process material waste in the subsequent manufacturing process. The pressure touch detection circuit comprises n pressure sensors, n first switch tubes, n second switch tubes and n control signal connection terminals; the first end of the ith first switch tube is electrically connected with the first end of the ith pressure sensor; the second end of the ith first switch tube is electrically connected with a first test connection terminal; the first end of the ith second switch tube is electrically connected with the second end of the ith pressure sensor; the second end of the ith second switch tube is electrically connected with a second test connection terminal; and the ith control signal connection terminal is electrically connected with a control end of the ith first switch tube and a control end of the ith second switch tube.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pressure touch detection circuit, method and display panel. 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. [0003] The pressure-sensing sensor is integrated on the display panel, but due to the process and other reasons, the pressure-sensing sensor may be defective due to disconnection and other reasons, resulting in the final display panel not working properly due to the defective pressure-sensing sensor, resulting in subsequent Waste of process materials in the process.
