Abstract

The invention provides a head mounted display. The head-mounted display comprises two display units which are respectively arranged in front of two eyes of a user. Each display unit comprises a display device, a Fresnel lens and a plurality of moth eye structures, the Fresnel lens is disposed between the display device and one eye of the user, and the plurality of moth eye structures are located on at least one surface between the display device and one of the eyes of the user.

Description

technical field [0001] The present invention relates to a display, in particular to a head-mounted display. Background technique [0002] Head-mounted displays usually adopt the form of goggles or helmets to place the display device in front of the user's eyes, and project the image light output by the display device into the user's eyes through lens elements. In order to reduce the size and weight of the head-mounted display, the existing head-mounted display uses a Fresnel lens as a light guiding element, but this leads to serious stray light problems. [0003] figure 1 It is a partial schematic diagram of an existing head-mounted display 1 . Please refer to figure 1 , the image light B output by the display device 10 tends to undergo interfacial reflection R on the surface S11B of the Fresnel lens 11 during transmission toward the user's eyes E, thereby forming stray light S. In addition, the stray light S may be reflected by the display device 10 to complicate / severe...
