The invention discloses a display panel and a display device. The display panel includes an organic light-emitting display panel, a fingerprint identification module, and an angle-limiting film; At least one fingerprint identification unit performs fingerprint identification according to the light reflected to the fingerprint identification unit via the touch body; the angle limiting film is located between the organic light-emitting display panel and the fingerprint identification module, and for the light reflected to the fingerprint identification unit via the touch body, The transmittance of light rays with an incident angle smaller than the transmission angle relative to the angle-defining film is A 1 ; Among the light rays reflected to the fingerprint recognition unit via the touch body, the transmittance of light rays with an incident angle greater than the transmission angle relative to the angle-limited film is A 2 ;A 1 >A 2 >0. Through the technical solution of the present invention, under the premise of not affecting the fingerprint identification accuracy, the phenomenon of crosstalk is effectively avoided, and the difficulty of making the angle-limiting film is reduced.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] Since fingerprints are inherent to each person, they are unique. With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. In this way, before operating the display device with fingerprint recognition function, the user only needs to touch the fingerprint recognition module of the display device with his finger to perform authority verification, which simplifies the authority verification process. [0003] In the existing display device with fingerprint identification function, the fingerprint identification module generally detects the light irradiated to the fingerprint identification unit through the touch body (such as a finger), that is, the rid...
