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

As shown in FIG. 1, a first embodiment of the fingerprint identification display panel of present disclosure includes a substrate 10 and a plurality of sub-pixel regions defined by a plurality of gate lines S and a plurality of data lines D intersected. The plurality of sub-pixel regions include a plurality of first sub-pixel regions 1 and a plurality of second sub-pixel regions 2.

As shown in FIGS. 1 and 2, a first driving circuit 5 and a first light-emitting unit 3 electrically connected with the first driving circuit 5 are sequentially disposed on the substrate 10 and located in the plurality of first sub-pixel regions 1. The first driving circuit can adopt a 7T2C circuit. Of course, in other exemplary embodiments of present disclosure, the first driving circuit 5 may further include other devices. For example, in order to implement a threshold compensation function, the first driving circuit 5 may further include a compensation transistor and more capacitive devices, and the like. This will not be particularly limited in the exemplary embodiment.
