Problems solved by technology

[0002] We live in a three-dimensional world, but traditional display technologies only provide two-dimensional displays that lack depth information
Two-dimensional display greatly limits the amount of information that people can acquire to understand the colorful world
The existing light field near-eye display technology adopts the spatial-multiplex method, which uses a lens array to generate images of multiple viewing angles to achieve the light field effect, but this method also reduces the resolution of the image

Abstract

Provided in the invention is a near-to-eye display device comprising an image output module, a code aperture module, and a light guide assembly. The image output module is used for providing at leastone image. The code aperture module is used for coding light of at least one image from the image output module and generating at least one left-eye image and at least one right-eye image. The light guide assembly is used for transmitting the left-eye image and the right-eye image respectively in different directions.

Description

technical field [0001] The invention relates to a near-eye display device. Background technique [0002] We live in a three-dimensional world, yet traditional display technologies only provide two-dimensional displays that lack depth information. The two-dimensional display greatly limits the amount of information that people can acquire to recognize the colorful world. The rapid development of electronic technology, optical technology and optoelectronic technology has promoted the development of three-dimensional display technology. Three-dimensional display technology provides depth information of displayed objects, which meets the needs of modern people for information acquisition. Therefore, 3D technology has been widely concerned in academia and business circles. [0003] Light field near-eye display technology is the easiest way to realize 3D display. In the near-eye display, the concept of light field reconstruction is introduced. For any three-dimensional reconst...
