Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel comprises a display zone, wherein the display zone comprises a fingerprint identification zone; the fingerprint identification zone comprises a fingerprint identification circuit; the fingerprint identification circuit comprises fingerprint identification units and a plurality of signal lines; a first color sub-pixel, a second color sub-pixel, a third color sub-pixel and a white sub-pixel, which are distributed in an array mode, are arranged on the display panel; eachsignal line comprises at least one first signal lines; and each of the first signal lines comprises a bending part. Because the bending parts are overlapped with non-opening zones of the white sub-pixels in the front projection direction being perpendicular to the direction of a light-out surface of the display panel, an accommodating space is formed between the bending parts and grid lines corresponding to the row of sub-pixels, and the accommodating space can be used for configuring at least a part of elements in the fingerprint identification circuit, and thus, circuit elements arranged between the two adjacent rows of sub-pixels are reduced, the transmittance of the display panel can be maximized, and the area of opening zones of the sub-pixels with three colors including red, green and blue is also improved.

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 display technology and full screen technology, it has become a trend to integrate fingerprint recognition into the display area of ​​the display panel. Since a fingerprint identification circuit is arranged in the fingerprint identification area, and the fingerprint identification circuit includes a plurality of signal lines, these signal lines will occupy the area of ​​the display area and reduce the aperture ratio of the pixels in the display area. [0003] On the other hand, considering that the white sub-pixel has higher transmittance, the related art usually introduces the white sub-pixel to improve the utilization rate of the backlight. However, for a display area with the same area, the increase of the white sub-pixel will lead to a decrease in the area of ​​the o...
