Problems solved by technology

The existing naked-eye 3D technology is mainly divided into two types: spatial multiplexing and time multiplexing. The time-division multiplexing 3D display is an autostereoscopic display based on time multiplexing and the existing directional backlight technology. However, the existing directional backlight Most of the light sources are equipped with a light guide plate with a unit cross-section on the surface. The outgoing light after the refraction of the light guide plate is relatively large, and the loss of light is large during the refraction process, so crosstalk is easy to occur and the brightness will be higher. In addition, the existing directional backlight light source can only realize two-viewpoint naked-eye 3D display due to the design of its light guide plate

Embodiment approach 1

[0034] Such as Figure 1-Figure 3 As shown, a multi-viewpoint full-resolution autostereoscopic display screen has multiple viewpoints, including a backlight module 1, a first polarizer 2, a black and white liquid crystal substrate 3, a second polarizer 4, Plano-convex cylindrical lens array plate 5, color liquid crystal display substrate 6, third polarizer 7 and microcontroller module 8,

[0035] Preferably, the frames of the backlight module 1, the first polarizer 2, the black and white liquid crystal substrate 3, the second polarizer 4, the plano-convex cylindrical lens array plate 5, the color liquid crystal display substrate 6 and the third polarizer 7 are all arranged There is a black outer frame (not shown in the figure), which is used to prevent stray light from entering the corresponding backlight module 1, first polarizer 2, black and white liquid crystal substrate 3, second polarizer 4, plano-convex cylinder Inside the lens array plate 5 , the color liquid crystal d...

Embodiment approach 2

[0049] Such as Figure 7 As shown, the difference between this embodiment and the first embodiment is that the polarization direction of the first polarizer 2 is horizontal, the polarization direction of the second polarizer 4 is vertical, the polarization direction of the third polarizer 7 is horizontal, and the backlight The second incident light 112 emitted by the module 1 is converted into the longitudinally polarized second transversely polarized light 212 by the first polarizer 2, and the black and white liquid crystal display substrate 3 loads electrical signals in different areas in turn to open the corresponding liquid crystal switches, and the second transversely polarized light 212 can be deflected in the area where the electrical signal is loaded, converted into longitudinally polarized light, and not deflected in the area where the electrical signal is not loaded to maintain horizontally polarized light. The second polarizer 4 is arranged on the black and white liq...

Abstract

The invention discloses a multi-view full-resolution free three-dimensional display screen. The multi-view full-resolution free three-dimensional display screen comprises a backlight module, a first polaroid, a black and white liquid crystal substrate, a second polaroid, a plano-convex cylindrical lens array plate, a color liquid crystal display substrate, a third polaroid and a microcontroller module, the backlight module, the first polaroid, the black and white liquid crystal substrate, the polaroids and the plano-convex cylindrical lens array plate are tightly arranged in sequence, the plano-convex cylindrical lens array plate is provided with a flat plate surface and a convex cylindrical surface, the convex cylindrical surface is provided with a plurality of vertical micro-cylindricallenses which are arranged next to one another; the focuses of the vertical micro-cylindrical lenses are positioned on the flat plate surface, the flat plate surface is arranged towards the second polaroid, the convex cylindrical surface is arranged towards the color liquid crystal display substrate, and the color liquid crystal display substrate and the third polaroid are tightly arranged. The multi-view full-resolution free three-dimensional display screen has the advantages of being not prone to crosstalk and small in brightness loss, and can achieve multiple viewpoints of more than two viewpoints at the same time.

Description

technical field [0001] The invention relates to the technical field of naked-eye 3D, in particular to a multi-viewpoint full-resolution autostereoscopic display screen. Background technique [0002] With the continuous development of display technology and the appearance of 3D products, in addition to the traditional technology of wearing 3D glasses, there has also been a naked-eye 3D technology that does not need to wear 3D glasses. The existing naked-eye 3D technology is mainly divided into two types: spatial multiplexing and time multiplexing. The time-division multiplexing 3D display is an autostereoscopic display based on time multiplexing and the existing directional backlight technology. However, the existing directional backlight Most of the light sources are equipped with a light guide plate with a unit cross-section on the surface. The outgoing light after the refraction of the light guide plate is relatively large, and the loss of light is large during the refract...
