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.
