Problems solved by technology

Among them, the holographic projection type 3D display uses the principle of light interference and diffraction to realize the recording and reproduction of 3D images. Although it can achieve the naked-eye 3D effect, it has complex equipment, poor stability, high cost, small viewing angle, and difficult man-machine. Disadvantages such as interaction

For example, patent CN 106292163 discloses a holographic projection device and an operating method of the holographic projection device. The device uses multiple reflective projection plates to project multiple images output by multiple displays to the apex to form a holographic image, but the equipment is complicated in technology and Strict requirements on process accuracy and high price are not conducive to mass production and use; patent CN108628088 discloses a holographic projection device, which uses optical channels to enlarge and project the output image of the display screen onto a pyramid-shaped holographic projection film to form a holographic image, but the device Due to the use of a single display screen to output image projection, the size of holographic projection is limited, and it is not conducive to human-computer interaction

[0004] Among them, the visual aid / grating 3D display requires the user to wear special observation equipment or add a grating device to the display screen to realize the 3D display function, which has disadvantages such as inconvenient use, limited display viewing angle, and difficulty in human-computer interaction.

For example, the patent CN 105681778 discloses a three-dimensional display device and its driving method. The device uses a rear grating to output left and right eye views according to the position of the user's human eyes to achieve a full-view three-dimensional display effect. The position is adjusted to output the left and right eye views. When multiple people observe the same screen, the display effect will be inconsistent.
