Description
Technical Field
For a conventional 3D Advertising light Box (3D Advertising Lighting Box, hereinafter referred to as 3D light Box), a lens array module (hereinafter referred to as lensicular module) is generally used to display a naked 3D static image, so as to achieve the purpose of providing a 3D dedicated light Box. For the 3D special lamp box, the invention provides a device capable of displaying 2D and 3D images simultaneously, so as to increase the function of image display of the conventional 3D lamp box and achieve the effect of greatly improving advertisements.
Background
Fig. 1-2 are schematic diagrams of a conventional 3D light box structure and 3D still image display. The conventional 3D light box 1 is mainly composed of a lens array (lenticulars) component 10, a 3D multi-view synthetic image 20 and a backlight 30.
As shown in fig. 2, the lens array (lenticulars) assembly 10 is made of a transparent plastic material with a sheet shape, wherein one surface, called a 3D structure surface 11, has a structure of a plurality of cylindrical lenses; on the other hand, the printing surface 12 is referred to as a printing surface, and the 3D Multi-View Combined 3D Image 20 is printed on the printing surface 12 by a lithographic process. The 3D multi-View composite Image 20 is composed of n Single views (Single View Image) VKThe synthesized image is composed of n is the total number of views, k is the number of view numbers, and 0 ≦ k ≦ n-1.
As shown in fig. 2, for the 3D multi-view composite image 20, the illumination by the backlight 30 and the lens array (lenticulars) component 10The visual separation effect can be achieved at the optimal viewing distance Z0N Optimal Viewpoints (OVP) P on an OVDkRespectively presenting a single-view image Vk。
For the left eye L and the right eye R respectively located at the optimal viewpoint Pk、Pk+1For the viewer, the left eye L and the right eye R of the viewer can respectively view a pair of single-view images V with parallaxk、Vk+1. Thus, the viewer can view a 3D image. Here, in order to clearly show the relationship between the display structures and the viewing-related positions, a coordinate system XYZ is set, the X axis is set in the horizontal direction, the Y axis is set in the vertical direction, the Z axis is set perpendicular to the 3D structure surface 11, and Z is set to 0 on the 3D structure surface 11. Thus, the viewing position is located at Z>And 0 region.
However, the naked eye technology, namely, the Auto-Stereoscopic (Auto-Stereoscopic) technology, whether the method using lenticule or the Parallax Barrier (paralax Barrier) is limited in the viewing freedom (viewfreedom), that is, as shown in fig. 3, for any optimal viewpoint PkThere is a single viewing area 13 within which the viewer can view a preferred 3D image (as indicated by the diamond shape). The preferred 3D image is the single visual image V viewed by the viewer in the single visual area 13kIn the above, it has a low degree of ghost (Cross-talk). Generally, when the ratio of the ghost is less than 10%, the viewer cannot easily perceive the existence of the ghost, and thus a better 3D image can be viewed. Therefore, when the naked-eye technology is applied to a 3D light box, the advertisement effectiveness is seriously reduced due to the lack of a limited viewing freedom.
