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.

Abstract: Provided is a near-eye display device including: a base substrate including first and second surfaces opposite to each other, an optical element array on the first surface, and a pixel island array and a sensor array that are on the second surface and are coupled to each other. The pixel island array emits first pixel light to the optical element array, such that the first pixel light passes through the optical element array and then reaches a human eye. The sensor array receives light of the first pixel light reflected by the human eye, determines a position of a pupil center of the human eye according to an intensity distribution of the reflected light, determines pixels corresponding to the position of the pupil center in the pixel island array, and controls the pixels to emit second pixel light.
