Problems solved by technology
When the viewing situation changes, it is likely to cause a bad viewing experience for the user. For example, the brightness of the viewing environment increases, the user's viewpoint shifts or moves, etc.
That is to say, the naked-eye 3D display based on conventional face recognition or human eye tracking has the problem of single display mode and inflexibility
[0005] In addition, the conventional naked-eye 3D display is realized through the traditional 2D display panel, resulting in the display resolution being multiplied by the number of viewpoints.
Moreover, in order to maintain a high-definition display, it is necessary to transmit images whose resolution is multiplied by the number of viewpoints, which causes the problem of too much signal transmission and a surge in rendering calculations.

Embodiment Construction
[0053] In order to understand the features and technical contents 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 with reference to the accompanying drawings, which are for reference only and are not intended to limit the embodiments of the present disclosure.
[0054] definition
[0055] In this article, "naked eye 3D (stereoscopic) display" refers to the technology that users (viewers) can observe 3D display images on a flat display without wearing glasses for 3D display, including but not limited to "parallax barrier", "parallax barrier", "parallax barrier", "parallax barrier" Lenticular Lens", "Pointing Backlight" technology.
[0056] Herein, "multi-viewpoint" has the conventional meaning in the art, 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 th...

This application relates to naked-eye 3D display technology, and discloses a 3D display device, including: a multi-viewpoint naked-eye 3D display screen, including a plurality of composite pixels, and each composite pixel in the plurality of composite pixels includes a plurality of composite sub-pixels, and a plurality of Each composite sub-pixel in the composite sub-pixel is composed of multiple sub-pixels corresponding to multiple viewpoints; the human eye tracking device is configured to obtain the spatial position of the user's eyes; the 3D processing device is configured to obtain the spatial position of the user's two eyes A view point is determined, and a sub-pixel corresponding to the view point among the multiple composite sub-pixels is rendered based on the received 3D signal. The above-mentioned 3D display device can realize high-quality naked-eye 3D display. The application also discloses a 3D display method and a 3D display terminal.
Description
technical field [0001] The present application relates to naked-eye 3D (stereoscopic) display technology, for example, to a 3D display device, a 3D display method, and a 3D display terminal. Background technique [0002] 3D (3D) imaging is one of the hottest technologies in the video industry, driving the technological change from flat display to 3D display. 3D display technology is a key part of the 3D imaging industry, and is mainly divided into two categories, namely glasses-type 3D display and naked-eye 3D display technology. Glasses-free 3D display technology is a technology in which users can watch 3D display images without wearing glasses. Compared with the glasses-type 3D display, the naked-eye 3D display belongs to the free 3D display technology, which reduces the constraints on the user. [0003] Glasses-free 3D display is based on viewpoints. Recently, a multi-viewpoint naked-eye 3D display has been proposed, so that a sequence of parallax images (frames) is for...
