摘要

A fingerprint identification display panel includes: a substrate; a plurality of sub-pixel regions including a plurality of first, second sub-pixel regions. A first driving circuit and a first light-emitting unit electrically connected thereto are sequentially disposed on the substrate and located in the plurality of first sub-pixel regions. A light shielding layer having through holes are disposed on the substrate. A plurality of light detection units are disposed at a side of the light shielding layer adjacent to the substrate, and corresponds to through holes one by one. At least one through hole is disposed in the second sub-pixel region, and a ratio of an area of an orthographic projection of the through hole on the substrate to an area of an orthographic projection of the second sub-pixel region on the substrate is greater than or equal to 30%.

說(shuō)明書

A light shielding layer 11 is disposed on the substrate 10, and the light shielding layer 11 includes a plurality of through holes 111; a plurality of light detection units 4 are disposed at a side of the light shielding layer 11 adjacent to the substrate 10. The plurality of through holes 111 and the plurality of light detection units 4 are correspondingly disposed one by one. At least one of the plurality of through holes 111 is disposed in the second sub-pixel region 2, and a ratio of an area of an orthographic projection of the through hole 111 on the substrate 10 to an area of an orthographic projection of the second sub-pixel region 2 on the substrate 10 is about 50%.
