Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0029] figure 1 It is a structural schematic diagram of an existing pressure sensor. see figure 1 , the pressure sensor 13 includes: a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a first power signal input terminal Vin1, a second power signal input terminal Vin2, a first induction signal measurement terminal Vout1 and the second sensing signal measuring terminal Vout2. The first end of the first resistor R1 and the first end of the fourth resistor R4 are electrically conn...

Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate and at least one pressure sensor. The pressure sensors are formed on the substrate; each of firstresistors and fourth resistors of the pressure sensors comprises at least one rectangular first-category sub-resistor and at least one rectangular second-category sub-resistor; the long edges of the first-category sub-resistors of the first resistors and the long edges of the second-category sub-resistors of the fourth resistors are parallel to first directions; the long edges of the second-category sub-resistors of the first resistors and the long edges of the first-category sub-resistors of the fourth resistors are parallel to second directions; the first-category sub-resistors are made of P-type (positive-type) semiconductor materials, and the second-category sub-resistors are made of N-type (negative-type) semiconductor materials. The display panel and the display device have the advantages that the problems of great measurement accuracy difference of existing pressure sensors at different environmental temperatures and poor pressure sensing and detecting performance of the existing pressure sensors can be solved by the aid of the display panel, and the pressure sensing and detecting performance of the display panel can be improved.

Description

technical field [0001] Embodiments of the present invention relate to a touch pressure detection technology, and in particular, to a display panel and a display device. Background technique [0002] At present, display panels 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. Since different materials have different sensitivities to strain, in order to make the pressure sensor have higher...
