Abstract

The invention discloses a display panel and a display device. The display panel comprises a display region and a non-display region and also comprises a substrate, a pixel unit and biometric feature identification units, wherein the pixel unit and the biometric feature identification unit are arranged at the display region, the display region comprises a plurality of pixel regions, the plurality of pixel regions are arranged in an array way, each pixel region comprises a plurality of pixel units and at least one biometric feature identification unit, the plurality of pixel units in each pixelregion are arranged in a way encircling at least one biometric feature identification unit, each pixel unit comprises a plurality of sub-pixels, the corresponding sub-pixels in arbitrary two adjacentpixel units are symmetrically arranged, the corresponding sub-pixels in two adjacent pixel units can share an opening of a mask, and thus, the process accuracy and the cost of the high-accuracy metalmask can be reduced; and moreover, the biometric feature identification units are arranged in each pixel region, the sensing areas of the biometric feature identification units can be expanded, and the performance of the biometric feature identification units is improved.

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] With the advent of the trend of full-screen smartphones, traditional fingerprint recognition technology will gradually be eliminated, and off-screen fingerprint recognition technology will gradually become the mainstream. [0003] In the prior art, the under-screen fingerprint recognition technology mainly includes optical fingerprint recognition. In the optical fingerprint identification technology, the optical fingerprint identification detector is generally located under the screen of the display panel. The light from the display panel irradiates the fingerprint, and the light returned from the fingerprint passes through the display panel and irradiates to the optical fingerprint recognition detector, which analyzes the light to realize fingerprint recognition. However, the area o...
