Problems solved by technology

[0003] In order to solve the problem of user fatigue and dizziness caused by near-eye display devices, the light field display can adopt integrated imaging display of microlens array or deep fusion display of multi-screen display. Among them, integrated imaging display uses microlens array, and its display resolution Depending on the size of the microlens unit, there is a problem of display resolution degradation; while using depth fusion display, although the problem of resolution degradation is solved, the depth of field range of the depth fusion display is affected by its first imaging surface and the last imaging surface. The distance between the positions is limited, that is, the depth of field of the 3D image generated by it is between the first and the last imaging surface, and there is a problem of depth of field limitation

Abstract

The invention discloses a near-eye display device and a near-eye display method, relates to the field of display technology, and achieves the purpose of realizing that the near-eye display device has the advantages of high resolution and large depth of field. The main technical solution of the present invention is: the display element displays the 1st-nth image at the 1st to nth time sequence, and displays the n+1th image at the n+1th time sequence; the polarization conversion element, the polarization conversion element converts the The light of the 1-th image is converted into a first linearly polarized light, and the light of the n+1th image is converted into a second linearly polarized light, wherein the first linearly polarized light and the second linearly polarized light The polarization directions are different; the first light modulation element is used to perform deep fusion imaging on the first linearly polarized light; the second light modulation element performs integrated imaging on the second linearly polarized light; the light projection element projects the projection element The first linearly polarized light and the second linearly polarized light are transmitted or reflected to display a virtual image.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a near-eye display device and a near-eye display method. Background technique [0002] Augmented Reality (AR, Augmented Reality) is a technology that uses virtual objects or information to augment real scenes, and is widely used in scientific research, military, industry, games, video, education and other fields. At present, the mainstream near-eye display system applied to augmented reality generally adopts a micro image display as an image source, and cooperates with a traditional visual optical system to realize enhanced display. [0003] In order to solve the problem of user fatigue and dizziness caused by near-eye display devices, light field display can adopt integrated imaging display of microlens array or deep fusion display of multi-screen display. Among them, integrated imaging display uses microlens array, and its display resolution Depending on the size of the micro...
