Embodiment Construction

[0045] In order to understand the characteristics and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present disclosure.

[0046] In this article, "naked-eye three-dimensional (or called 3D) display" refers to a technology that allows users to observe 3D images on a display without wearing glasses for 3D display.

[0047] Herein, "multi-viewpoint" has a conventional meaning in the field, which means that different images displayed by different pixels or sub-pixels of the display screen can be viewed at different positions (viewpoints) in space. In this context, multi-view will mean at least 3 viewpoints.

[0048] Herein, "grating" has a broad interpretation in the art, including but not lim...

Abstract

The present application relates to the technical field of 3D display, and discloses a 3D display device. The device comprises a multi-view naked eye 3D display screen comprising a plurality of composite pixels, each of the plurality of composite pixels comprising a plurality of composite sub-pixels, each of the plurality of composite sub-pixels comprising a plurality of sub-pixels corresponding to a plurality of views of the 3D display device; a visual angle determining device is configured to determine a user visual angle of the user; a 3D processing device is configured to render corresponding sub-pixels in the plurality of composite sub-pixels according to the depth-of-field information of the 3D model based on the visual angle of the user. The device can solve the problem of naked eye 3D display distortion. The invention further discloses a 3D image display method.

Description

technical field [0001] The present application relates to the technical field of 3D display, for example, to a 3D display device and a 3D image display method. Background technique [0002] Glasses-free 3D display technology has become a research hotspot in imaging technology because it can present a lifelike visual experience to users. [0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in related technologies: users at various locations see the same 3D images, only users within a certain range will have real feelings, and other users outside the range will Display distortion is felt. [0004] This background art is only for the convenience of understanding related technologies in this field, and is not regarded as an acknowledgment of prior art. Contents of the invention [0005] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summar...
