Abstract

The invention discloses a display panel and an electronic device. The electronic device comprises a display panel. The display panel comprises a display module and a fingerprint module. The display module comprises a plurality of pixel units, and the plurality of pixel units form a display array; the fingerprint module comprises a plurality of photosensitive pixel points, and the plurality of photosensitive pixel points form a photosensitive array; an included angle which is not zero exists between the row direction of the display array and the row direction of the fingerprint module. Light beams emitted by the display panel comprise two parts, namely a display light beam directly reaching the fingerprint module and a target light beam reaching the fingerprint module after reflection; thedisplay array in the display module and the photosensitive array in the fingerprint module are arranged in a staggered manner, so that the display light beam and the target light beam are prevented from being superposed to form a moire pattern, and the fingerprint recognition accuracy of the fingerprint module to a user finger is ensured.

Description

technical field [0001] The present application relates to the field of intelligent display, in particular to a display panel and an electronic device. Background technique [0002] With the advancement of technology, the technology of fingerprint unlocking under the screen is widely used. Since the fingerprint unlocking under the screen can increase the screen ratio of the electronic device, it is more and more sought after by users. The fingerprint module is arranged under the display module so as to avoid affecting the normal display of the electronic device. When the user uses the fingerprint unlocking function under the screen, the user needs to press the finger on the designated area, and part of the light beam emitted by the display module is emitted in a direction away from the fingerprint module, reaches the user's finger, and then is reflected towards the fingerprint module. The direction of the group to emit. The frequency of the reflected light is close to that ...
