Display panel, display screen, and display device

Abstract

The invention discloses a display panel, a display screen, and a display device. An optical sensor device can be arranged in the lower side of a display structure of the panel to implement a fingerprint detection function. The display structure comprises: a plurality of first light emitting groups, wherein each light emitting group comprises a plurality of first type sub-pixels, each first type sub-pixel comprises a first transparent area and a first light emitting area, the first light emitting areas of the adjacent first type sub-pixels are not adjacent to each other, and furthermore, in theadjacent light emitting groups, the first light emitting areas of the adjacent first type sub-pixels are not adjacent to each other; and / or, a plurality of second light emitting groups, wherein eachlight emitting group comprises a second transparent area and a second light emitting area, the second light emitting area comprises a plurality of closely adjacent second type sub-pixels, the second type sub-pixels do not comprise transparent areas, and the maximum size of the pattern of the second light emitting area is less than the allowable maximum blank space when the fingerprint detection function is implemented. The panel can disperse the shadow gathering brought by the opaque light emitting areas, which improves the accuracy of fingerprint recognition to a certain extent.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a display panel, a display screen and a display device. Background technique

[0002] With the rapid development of display terminals, more and more fingerprint identification sensors are applied to display terminals. Fingerprint is the texture formed by the uneven skin on the surface of the finger. It has the characteristics of uniqueness and stability. Based on this, identification can be realized through fingerprints. As a photoelectric sensor, the fingerprint recognition sensor can accurately identify the user's fingerprint and authenticate the user. Therefore, more and more display terminals are equipped with fingerprint recognition sensors. For example, fingerprint recognition sensors are widely used in screen unlocking of mobile terminals such as mobile phones. In order to realize a full screen in mobile terminals such as mobile phones, the fingerprint recognition senso...
