Abstract: An augmented reality display device and a pair of augmented reality glasses are provided. The augmented reality display device includes a substrate, an imaging element and a first optical element. The substrate includes a first side and a second side opposite to each other. The imaging element is configured to display a primary virtual image formed by virtual image light. The first optical element is configured to receive the virtual image light, orient the virtual image light to magnify the primary virtual image into a secondary virtual image, and make the virtual image light exit from the first optical element in a direction from the second side to the first side.

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.
