Embodiment Construction

[0040] 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.

[0041] In this paper, "naked-eye three-dimensional (3D) display" refers to the technology that users can observe 3D display images on a flat-panel display without wearing glasses for 3D display, including but not limited to "parallax barrier", "cylindrical lens", "Pointed backlight" technology.

[0042] 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 lea...

Abstract

The invention relates to the technical field of naked-eye 3D display, and discloses a multi-view naked-eye 3D display method, which comprises the following steps: acquiring a distance between a user and a multi-view naked-eye 3D display screen; and in response to the change of the distance, dynamically rendering the sub-pixels in the composite sub-pixels in the multi-view naked-eye 3D display screen based on the 3D signal. According to the method, multi-view flexible projection can be realized, and the calculation amount of transmission and rendering can be reduced. The invention further discloses a multi-view naked eye 3D display device.

Description

technical field [0001] The present application relates to glasses-free 3D display technology, for example, to a multi-view glasses-free 3D display device and a 3D image display method. Background technique [0002] At present, the multi-view glasses-free 3D display technology utilizes multiple independent pixels of the display panel to project multiple viewpoints of space. [0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art: the traditional multi-view point projection mode is single, which is not suitable for occasions where the viewing situation changes, for example, the user moves away from or approaches the display panel. [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...
