Abstract
A display panel includes a substrate, a plurality of pixel units, a first color film, and an optical sensing layer. Each pixel subunit in each pixel unit includes a light-emitting portion. The optical sensing layer is sandwiched between the first color film and the substrate, configured to detect optical signals from an object facing the display panel, and includes a plurality of optical sensing portions, each arranged such that an orthographic projection thereof on the substrate is substantially covered by an orthographic projection of the first color film on the substrate, yet is not overlapped with an orthographic projection of the light-emitting portion of each pixel subunit on the substrate. A lens layer may be over the optical sensing layer, and an orthographic projection thereof on the substrate substantially covers an orthographic projection of each optical sensing portion on the substrate.
