Description

 Stereoscopic display device

[Technical Field]

The present invention relates to the field of stereoscopic display technologies, and in particular, to a stereoscopic display device.

 【Background technique】

With the development of display technology, people can no longer be satisfied with two-dimensional (Two Dimensions, 2D) the plane displays the image, but needs to have three dimensions (Three Dimensions, 3D) stereoscopic display devices provide deeper, more comprehensive information. The basic principles of 3D stereo imaging include:

There is a certain distance between the left eye and the right eye. Therefore, the viewing angles of the two eyes are slightly different when viewing the scene. The difference in the viewing angle is such that the left eye sees the left image and the right eye sees the right image, and the left image and the right image do not. The same, after the synthesis of the brain will produce a three-dimensional feeling, to achieve the purpose of viewing three-dimensional stereoscopic images.

Existing solutions for realizing viewing three-dimensional stereoscopic images include:

First, people first use two cameras to imitate people's left and right eyes to shoot a movie at the same time, and then simultaneously project two movies on one screen. At this time, the viewer needs to wear a polarized glasses to watch. Three-dimensional display of images;

2. The viewer wears the shutter glasses. When the left three-dimensional stereoscopic image is scanned and appears on the screen of the display, the left electronic lens of the shutter glass is opened, and the right electronic liquid crystal shutter is closed. State, on the other hand, when the right three-dimensional stereoscopic display image is scanned on the screen of the display, the right electronic liquid crystal shutter of the shutter glasses is controlled to be in the open state, and the left electronic lens of the shutter glasses is closed, thereby making the viewing The user can see the left or right three-dimensional stereoscopic display image, and achieve the purpose of viewing the three-dimensional stereoscopic display image;

Third, let the viewer wear the helmet-type glasses, the left lens and the right lens of the glasses are each a micro-display, the left lens shows the left-eye image, and the right lens shows the right-eye image, so that people feel like entering a stereo Sense of virtual environment.

In summary, the conventional stereoscopic display device does not have a three-dimensional stereoscopic display image that can display naked eyes in the vertical direction, and can display a three-dimensional stereoscopic display image that is visible to the naked eye in the horizontal direction, and cannot realize the viewer. It is possible to achieve the purpose of viewing a three-dimensional stereoscopic image through the naked eye.
