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%.

說明書

According to an aspect of present disclosure, a fingerprint identification display panel includes: a substrate; a plurality of sub-pixel regions defined by a plurality of gate lines and a plurality of data lines intersected; wherein the plurality of sub-pixel regions include a plurality of first sub-pixel regions and a plurality of second sub-pixel regions; a first driving circuit and a first light-emitting unit electrically connected with the first driving circuit are sequentially disposed on the substrate and located in the first sub-pixel region; a light shielding layer is disposed on the substrate and includes a plurality of through holes; a plurality of light detection units are disposed at a side of the light shielding layer adjacent to the substrate, and the plurality of through holes are disposed to correspond to the plurality of light detection units one by one, wherein: at least one of the plurality of through holes 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%.

According to an embodiment of present disclosure, a second driving circuit and a second light-emitting unit electrically connected with the second driving circuit are disposed on the substrate and located in the second sub-pixel region, an orthographic projection of the second light-emitting unit on the substrate does not overlap with an orthographic projection of the through hole on the substrate, and an orthographic projection of the second driving circuit on the substrate does not overlap with the orthographic projection of the through hole on the substrate.
