Embodiment 1

[0062] Glasses-free 3D display devices are mainly divided into two types. The first kind, refer to figure 1 As shown in figure a, a lenticular lens 101 is set on the display screen 100; refer to figure 1 As shown in Figure b, the light emitted by the display screen has a certain directivity after passing through the lenticular lens, that is, the light emitted by the white area 102 of the display screen enters the right eye of the person, and the light emitted by the black area 103 of the display screen enters the human eye. left eye. The image displayed in the white area 102 of the display screen is different from the image displayed in the black area 103 , so that people's left and right eyes see different images at the same time, thereby forming parallax and further forming stereoscopic vision. However, the viewing angle of the lenticular lens display device is limited, and it can only display one view of 3D graphics, and cannot display complete 3D graphics information; me...

Embodiment 2

[0099] An embodiment of the present invention provides a display method of a display device according to Embodiment 1, the method includes:

[0100] S101. During the rotation of the display screen, sequentially input multiple different two-dimensional images obtained by rendering the three-dimensional graphics to be displayed to the display screen, wherein the input interval between any two adjacent two-dimensional images is less than or equal to that of human eyes Persistence of vision.

[0101] S102. Control the display screen to display the input image.

[0102] The display method is simple and easy to realize, and the 3D display effect is good.

Embodiment 3

[0104] An embodiment of the present invention provides a data generation device, including:

[0105] The image acquisition module is configured to acquire data of multiple different two-dimensional images of the three-dimensional graphics to be displayed from different angles.

[0106] The output module is configured to output the data of multiple different two-dimensional images to the control component of the display device according to the first embodiment.

[0107] An embodiment of the present invention provides a data generating device, which can generate and output data of multiple different two-dimensional images of three-dimensional graphics to be displayed.

[0108] Optionally, the above-mentioned image acquisition module includes multiple cameras.

[0109] refer to Figure 11 As shown, a plurality of cameras 20 are arranged around the three-dimensional figure to be displayed 21, and the cameras are configured to render the three-dimensional figure to be displayed f...

Abstract

The invention provides a display device, a data generation device and method and a display system, and relates to the technical field of display, and the display system can achieve a 360-degree dead-zone-free stray-light-free three-dimensional visual effect without wearing 3D glasses, thereby greatly improving the 3D display effect, and improving the user experience. The display device comprises adisplay screen, a driving assembly, a rotating assembly and a control assembly. The display screen can rotate along with rotation of the driving assembly; a rotating shaft is parallel to the light-emitting surface of a display panel; the display screen comprises the display panel and an optical assembly. Light emitted by the display panel comprises emergent light located on a reference surface, and the reference surface is perpendicular to the light emitting surface of the display panel and the rotating shaft of the display screen. The optical assembly is configured to adjust the emergent light located on the reference surface into collimated light perpendicular to the emergent surface of the display panel; the rotating assembly is configured to drive the assembly to rotate; and the control assembly is electrically connected with the display screen. The invention is suitable for manufacturing the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device, a data generation device and method, and a display system. Background technique [0002] With the development of science and technology and technological progress, 3D (three-dimensional) display technology has become a hot research field. Most of the existing 3D display devices require users to wear 3D glasses to watch, which is very troublesome and has poor user experience. Therefore, there is an urgent need to develop a naked-eye 3D display device that can achieve a 3D display effect without wearing 3D glasses. Contents of the invention [0003] Embodiments of the present invention provide a display device, a data generating device and method, and a display system. The display system can realize a 360° three-dimensional stereoscopic effect without dead zones and stray light without wearing 3D glasses, thereby greatly The 3D display effect is impro...
