The display device can be simply divided into a glasses system and a naked eye system in terms of appearance, the glasses system directly inputs parallax images to left and right eyes, and the naked eye system is a holographic display device that is observed without glasses.
The glasses holographic system adopts a separated (active and passive) mode, so that the right and left views can be observed in a binocular manner, and the problem of holographic image arrangement does not exist. In the holographic image display device of the naked eye system, except the holographic projection device, the rest of the holographic image display device can be classified as a free holographic image display device, and the principle is that a two-dimensional image obtained by a specific arrangement algorithm is shielded or refracted through an optical separation unit, so that a viewer can see an accurate parallax image, and holographic feeling is generated.
The naked eye free holographic display based on the binocular vision principle is mainly a grating free holographic display. The working principle is that the holographic grating is additionally arranged on the 2D display, and the holographic grating is mainly divided into two types: lenticular gratings and slit gratings. And through the holographic grating, the M-view angle holographic views displayed on the display sub-pixels are accurately projected to the left eye and the right eye of a viewer, so that the accurate display of the holographic image is realized. In addition, a new naked eye free holographic technology is provided, the transverse and longitudinal bidirectional holography is realized by utilizing the backlight of the display screen and a proper light splitting technology, so that a viewer can see correct holographic effects at different angles of the display screen, and the unidirectional holographic effect of the original grating free holographic display screen is expanded.
