Problems solved by technology

However, in the head-mounted display with this structure, the image beams incident on the light waveguide element and transmitted in the light waveguide element cannot effectively fill the cross-sectional area of ​​these beam splitters.
Therefore, users tend to see bright and dark stripes in the display screen of the head-mounted display, and feel that the display quality of the head-mounted display is not good

Abstract

The invention discloses an optical waveguide element and a head-mounted display device with the optical waveguide element. The optical waveguide element is used for transmitting an image beam. The optical waveguide element comprises an in-light surface, a first side surface, a second side surface, multiple splitters and at least one planer reflection structure, wherein the image beam enters the optical waveguide element from the in-light surface; the first side surface and the second side surface are parallel; the splitters are configured between the first side surface and the second side surface, and the splitters are parallel mutually and are arranged at intervals; the at least one planer reflection structure is configured between the splitters and the in-light surface; the planer reflection structure is parallel with the first side surface; and a gap exists between the planer reflection structure and the in-light surface. As the optical waveguide element comprises the planer reflection structure, a user does not see dark stripes easily in a display picture of the head-mounted display, and thus, the head-mounted display device with the optical waveguide element has a good display quality.

Description

Technical field [0001] The present invention relates to an optical waveguide element and a display device, and more particularly to an optical waveguide element and a head-mounted display device having the optical waveguide element. Background technique [0002] Near-eye displays (NED) and head-mounted displays (HMD) are the next generation killer products with great production potential. The related applications of near-eye display technology can be divided into augmented reality (AR) technology and virtual reality (virtual reality, VR) technology. As far as augmented reality technology is concerned, related developers are currently working on how to provide the best image quality under the premise of being thin and light. [0003] In the basic optical architecture for realizing augmented reality with a head-mounted display, the image beam used for display is emitted by the projection device and then reflected by the semi-reflective and semi-transmissive optical element to enter ...
