Problems solved by technology

[0005] Due to the periodicity of the Lens array or Barrier array, this periodic structure will interfere with the periodic distribution of the display units of the display panel, allowing the audience to see the moiré phenomenon that should not appear, and the moiré pattern affects the clarity of the stereoscopic display. , which can easily cause dizziness to the audience
[0006] In addition, the naked-eye stereoscopic display uses spectroscopic devices, which will form some fine particles in the picture, which will affect the clarity of the picture and form a rough feeling of the picture.

Embodiment 1

[0066] This embodiment provides a naked-eye three-dimensional display device, which includes a display panel and a light-splitting device. The display panel is composed of a series of display units for providing image display; Directional transmission to achieve light splitting. Different from the existing naked-eye three-dimensional display device, the naked-eye three-dimensional display device of this embodiment also includes a directional dimmer, which is made of a transparent material and placed on the side of the light splitting device away from the display panel. , comprising a plurality of dimming units capable of refracting light, and said dimming units will only deviate from the original light path in one direction after refracting one light. Herein, for a dimming unit, the plane perpendicular to its extending direction is called a radial plane, and the cross-sections of the dimming unit on each radial plane are the same. For the light splitting device, the plane per...

Embodiment 2

[0077] The difference between the naked-eye stereoscopic display device provided in this embodiment and the first embodiment is that a prism array is used instead of a lens array as a directional dimmer.

[0078] Such as Figure 4a with Figure 4b As shown, the directional dimmer 401 replaces the lens array in the first embodiment with a prism array, and the dimming unit on the directional dimmer 401 is a prism unit 4011, and the prism unit 4011 and the lens unit in the first embodiment scatter light The basic principle is the same. After refracting a ray, it will only deviate from the original optical path in one direction, and the ray after refracting the incident ray on the radial plane is still on the radial plane. At the same time, for the incident light incident on the same dimming unit at the same angle and different positions on the same radial plane, the refracted outgoing angles are not exactly the same, which also plays a role of "scattering". For dimming units su...

Embodiment 3

[0081] In the above two embodiments, the directional dimmer is placed on the side of the light splitting device away from the display panel. In this embodiment, the directional dimmer is placed between the light splitting device and the display panel. The directional dimmer may use a lens array or a prism array, and the light splitting device may use a lens array or a barrier array. Figure 5a It shows the structure and optical path changes when both the directional dimmer 201 and the light splitting device 102 use a lens array, Figure 5b It shows the structure and optical path changes when the directional dimmer 201 adopts a lens array and the light splitting device 107 adopts a barrier array, Figure 6a It shows the structure and optical path changes when the directional dimmer 401 adopts a prism array and the light splitting device 102 adopts a lens array, Figure 6b It shows the structure and light path changes when the directional dimmer 401 adopts a prism array and th...

Abstract

Disclosed are an autostereoscopic display device and corresponding terminal equipment. The autostereoscopic display device comprises a display panel, a spectroscopic device and a directional dimmer, wherein the directional dimmer is placed between the spectroscopic device and the display panel or placed on one side of the spectroscopic device far away from the display panel, the directional dimmer comprises a plurality of dimming units for refracting light rays, and the dimming units refract a light ray to deviate from an original light path in one direction. The invention further provides the terminal equipment comprising the autostereoscopic display device. The autostereoscopic display device and the terminal equipment use the directional dimmer to refract the light entering or exiting from the spectroscopic device, Moire patterns can be effectively eliminated, and grainy is weakened.

Description

technical field [0001] The present invention relates to naked-eye stereoscopic display technology, and more particularly, to a naked-eye stereoscopic display device and corresponding terminal equipment. Background technique [0002] The traditional naked-eye three-dimensional display device uses a lens array or a parallax barrier (barrier) array as a light-splitting device, and places the light-splitting device in front of a display panel that can provide image display signals. The panel can be LCD, PDP or OLED, etc. . [0003] Figure 1a with Figure 1b The basic structure of the naked-eye stereoscopic display device formed by the lens array and the barrier array is described respectively at 3 viewpoints. Figure 1a The naked-eye stereoscopic display device in includes a display panel 101 and a lens array 102 . The display panel 101 is composed of a series of display units 1011 for displaying first, second and third viewpoint images respectively. The lens array 102 is us...
