[0003] However, based on the structure of the current display panel, the light-transmitting areas in the fingerprint recognition area are scattered and the area of each light-transmitting area is relatively small. The amount of light in the area is less, resulting in low detection accuracy of fingerprint recognition, and it is impossible to accurately identify fingerprints

Embodiments of the present invention provide a display panel and a display device, relate to the field of display technology, and improve light transmittance and fingerprint recognition accuracy in a fingerprint recognition area. The display panel includes a fingerprint identification area, and the fingerprint identification area is provided with a plurality of repeating units, the repeating units include pixel units, and the pixel units include sub-pixel groups; the fingerprint identification area is also provided with a first signal line and a second signal line, and each sub-pixel group It is connected with a first signal line and a second signal line; for two adjacent sub-pixel groups in a pixel unit, the connection between the first signal line corresponding to one sub-pixel group and the second signal line corresponding to the other sub-pixel group The spacing between them is smaller than the spacing between the first signal line corresponding to the first sub-pixel group and the second signal line corresponding to the second sub-pixel group; wherein, the first sub-pixel group and the second sub-pixel group are respectively adjacent The two closest sub-pixel groups among the two pixel units. The above display panel is used to realize fingerprint recognition.
Description
【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] For the display panel with fingerprint recognition function, in order to better realize the full-screen design and avoid the fingerprint recognition area occupying the space of the non-display area, the display area can be reused as the fingerprint recognition area by using the under-screen fingerprint technology. [0003] However, based on the structure of the current display panel, the light-transmitting areas in the fingerprint recognition area are scattered and the area of each light-transmitting area is relatively small. The amount of light in the area is less, resulting in low detection accuracy of fingerprint identification, and it is impossible to accurately identify fingerprints. 【Content of invention】 [0004] In view of this, an embodiment of the present invention provides a display p...
