Abstract

The invention discloses a display panel and a display device, and belongs to the technical field of display, the display panel comprises a display area, and the display area comprises a fingerprint identification area and a non-fingerprint identification area; the display area further comprises touch control units, and the touch control units comprise a plurality of first touch control units and aplurality of second touch control units; the orthographic projection of the first touch units to the light-emitting surface of the display panel is located in the fingerprint identification area, andthe orthographic projection of the second touch units to the light-emitting surface of the display panel is located in the non-fingerprint identification area; in the touch operation process, the touch detection signal strength of the first touch units is the same as that of the second touch units. The display device comprises the display panel. During final touch detection, the touch detection semaphore detected by the second touch units in the non-fingerprint area can be consistent with the touch detection semaphore detected by the first touch units in the fingerprint area as much as possible, so that the problem of overexposure of the touch detection semaphore in the fingerprint area in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] With the development of electronic technology, touch display devices such as smart phones and tablet computers are more and more widely used in people's daily life, and the current touch display devices have more and more functions, providing users with more Much more convenient. However, while the touch terminal provides users with more convenience, it also carries a large amount of private information. Once the touch display device is lost, the private information will be leaked. Therefore, the security of the touch display device becomes more as important. Fingerprints are the lines formed by the bumpy skin at the end of human fingers, also called palm prints, which are the raised lines on the epidermis. Since human fingerprints are a combination of genetics and the environment, they are al...
