Abstract

A transparent display panel has a plurality of sub-pixel regions, which are divided into at least two display unit groups. The transparent display panel includes a first substrate and a second substrate assembled with each other, and a light exit control layer disposed therebetween. The first substrate includes a first base and a dimming component disposed on a side of the first base. The dimming component includes a plurality of dimming lenses. Each dimming lens is configured to transmit exit light of one sub-pixel region to human eyes and focus the exit light on a corresponding focal plane. The plurality of dimming lenses are configured to focus exit light of the at least two display unit groups on different focal planes. The focal planes are located at a side of the transparent display panel away from the human eyes.
