Abstract
A near-eye display apparatus is configured to be disposed in front of at least one eye of a user and includes an illumination system, a display device, and a micro-lens array. The illumination system is configured to provide an illumination beam including sub-illumination beams. The display device is located on a transmission path of the illumination beam. The sub-illumination beams form corresponding sub-illumination regions on the display device, and the display device is configured to convert the sub-illumination beams irradiating the display device and corresponding to the sub-illumination regions into sub-image beams. An exit angle of each sub-image beam emitted from the display device is less than or equal to 20 degrees. The near-eye display apparatus provided herein is capable of eliminating stray light and characterized by good quality.
