US 12,604,645 B2 · Display panel and display device

Abstract

A display panel includes a driving backplane, a light-emitting layer, a lens layer, and a cover plate. The light-emitting layer is arranged on a side of the driving backplane and includes a plurality of light-emitting devices. The lens layer is arranged on a side of the light-emitting layer away from the driving backplane and includes a plurality of lens groups. One lens group is arranged corresponding to at least one light-emitting device. The lens group includes a central lens and a peripheral lens surrounding the central lens. The central lens and the peripheral lens include an inner light-transmissive area and an outer light-transmissive area surrounding the inner light-transmissive area. The refractive index of the inner light-transmissive area is greater than that of the outer light-transmissive area in the same lens group. The cover plate is arranged on a side of the lens layer away from the driving backplane.
