Stereoscopic display

This invention relates to a display, and more particularly to a stereoscopic display.

With the advancement and development of science and technology, people's enjoyment of material life and spiritual level has always increased and never decreased. At a spiritual level, in this era of rapid technological advancement, people hope to realize the imaginative imagination through stereoscopic displays to achieve immersive effects. Therefore, how to make a stereoscopic display of a stereoscopic image or image becomes an object of today's stereoscopic display technology.

In the current display technology, the stereoscopic display technology can be roughly divided into an auto-stereoscopic view that the viewer can directly view with naked eyes and a stereoscopic view that needs to be worn with special design glasses. Among them, the naked eye stereoscopic display works mainly by using a fixed grating to control the images received by the viewer's left and right eyes. According to the visual characteristics of the human eye, when the left and right eyes respectively view the same image content but have two images with different parallax, the human eye observes the interpretation of the two images as a stereo image. However, the stereoscopic display quality presented by this method is affected by the viewing distance of the viewer and the distance between the two eyes, and there may be problems due to engineering problems, and the viewer may easily feel uncomfortable after watching the stereoscopic image for a period of time. The working principle of the glasses-type stereo display is mainly to display the left and right eye images by using the display, and the left and right eyes are divided by the selection of the glasses. Don't see the left and right eye images to form stereoscopic vision. Therefore, wearing glasses-type stereoscopic display technology can reduce problems caused by human factors engineering.
