Problems solved by technology

[0008] To sum up, the existing stereoscopic display devices do not have the function of displaying naked-eye-visible three-dimensional display images in the vertical direction, and can also display naked-eye-visible three-dimensional display images in the horizontal direction. Can achieve the purpose of viewing three-dimensional display images through the naked eye

Embodiment Construction

[0055] The principle of using the slit grating to realize the three-dimensional image visible to the naked eye includes: according to the parallax barrier principle, the images are arranged alternately, and the left and right eyes are captured and observed after passing through the slender grating. The images are separated due to parallax barriers, resulting in slightly different viewing angles of the two eyes. The difference in viewing angles causes the left eye to see the left image and the right eye to see the right image. The left image is different from the right image, which will be produced after synthesis by the brain Stereoscopic feeling, to achieve the purpose of watching three-dimensional stereoscopic display images.

[0056] The present invention provides a stereoscopic display device, which is applied in the technical field of stereoscopic display. The stereoscopic display device of the present invention uses a display to generate image signal light, and then the i...

Abstract

The invention discloses a three-dimensional display device. When the command that an image is displayed as a two-dimensional flat panel display image is received, both a first liquid crystal optical grating layer and a second liquid crystal optical grating layer become transparent states, and the two-dimensional flat panel display image is obtained; when the command that an image is displayed as a three-dimensional display image is received and the display direction of a displayer is detected to be the perpendicular direction, the first liquid crystal optical grating layer forms a slit grating, and the second liquid crystal optical grating layer becomes the transparent state; when the command that an image is displayed as the three-dimensional display image is received and the display direction of the displayer is detected to be the horizontal direction, the first liquid crystal optical grating layer becomes the transparent state, the second liquid crystal optical grating layer forms the slit grating, and the three-dimensional display image visible for naked eyes is obtained. Therefore, the functions that the three-dimensional display device can display the two-dimensional flat panel display image in the perpendicular direction and the horizontal direction, and can display the three-dimensional display image visible for the naked eyes are achieved.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a stereoscopic display device. Background technique [0002] With the development of display technology, people can no longer be satisfied with two-dimensional (Two Dimensions, 2D) plane display images, but need three-dimensional (Three Dimensions, 3D) stereoscopic display devices to provide a sense of depth and more comprehensive Information. The basic principles of 3D stereoscopic imaging, including: [0003] There is a certain distance between the left eye and the right eye, so the observation angles of the two eyes are slightly different when watching the scene. The difference in the observation angle makes the left eye see the left image, and the right eye sees the right image, and the left image and the right image are different. Similarly, after being synthesized by the brain, a three-dimensional feeling will be produced, and the purpose of viewing three-dim...
