Problems solved by technology

Since ghosting and stray light are difficult to eliminate, it is easy to cause visual fatigue when viewing such 3D images
At the same time, due to the influence of stray light, the viewing angle interval is usually set to be relatively large, resulting in incoherent viewing angles, and it is impossible to achieve a jump-free naked-eye 3D display effect
In addition, the existing glasses-free 3D display devices are bulky and difficult to integrate into small devices such as mobile phones

Embodiment Construction

[0037] The purpose of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] figure 1 is a schematic diagram of a three-dimensional display device according to an embodiment of the present invention.

[0039] figure 1 The illustrated device 10 includes a light source module 110 , a spatial light modulator 120 and a phase plate 130 . see figure 1 The spatial light modulator 120 is arranged in the propagation direction of the light beam B1 (hereinafter also referred to as the first light beam) emitted by the light source module 110, and it loads the multi-view mixed image information on the first light beam B1 by way of amplitude modulation to form the second light beam B1. Beam B2. The phase plate 130 is arranged on the propagating direction of the second light beam B2, and it uses the nanostructure unit to project the image of each viewing angle in the image carried by the second light beam B2 to a plurality of corresp...

Abstract

The invention relates to display technology and particularly relates to a device for realizing multi-view display of a naked eye three-dimensional image. A three-dimensional display device according to one aspect of the invention is characterized in that the device includes a light source module, configured to emit a first light beam; a spatial light modulator locating in the transmission direction of the first light beam and configured to loading multi-view mixed image information onto the first light beam through an amplitude modulation mode to form a second light beam; and a phase plate locating in the transmission direction of the second light beam, and having a diffraction structure configured to project images of different angles of view among images carried by the second light beamto multiple observation positions separately corresponding to the images of different angles of view.

Description

technical field [0001] The invention relates to display technology, in particular to a device for realizing multi-view display of naked-eye three-dimensional images. Background technique [0002] With the improvement of living standards and the rapid development of science and technology, realistic visual experience has become people's pursuit of display screens, and 3D display technology has emerged as the times require. Not only in the traditional display industry, but also in many fields such as multimedia and software development, there is an urgent need for the development and application of 3D display technology. Traditional 3D display technology requires additional auxiliary equipment (such as 3D glasses, etc.) to observe stereoscopic images, which greatly limits people's viewing freedom. Therefore, the development of naked-eye 3D display technology is the general trend. [0003] A hologram is an image that carries amplitude and phase information to truly reproduce ...
