Embodiment Construction

[0045] Such as Figure 4~5 Shown is a schematic diagram of the embodiment of the present invention. The present invention is a device capable of simultaneously displaying 2D and 3D dynamic images, that is, the composition 100 of the embodiment of the present invention, mainly using a first 2D dynamic image light source 110, a first image surface 120, a transparent substrate 130, a The second image surface 140, and a second 3D dynamic multi-view synthetic image light source 150 project the first 2D dynamic image light source 110 and the second 3D dynamic multi-view synthetic image light source 150 respectively onto the The method of the first image surface 120 and the second image surface 140 is used to simultaneously display a 2D dynamic image and a 3D dynamic image. That is, the viewer can watch the 2D dynamic image provided by the first image surface 120 in the area of ​​Z>0; and at the optimal viewing distance Z=Z 0 , the 3D dynamic image provided by the second image surf...

Abstract

The invention discloses a method capable of displaying 2D and 3D dynamic images simultaneously and a device. A first light source, a first image face, a transparent base material, a second image face and a second light source are mainly used. The first light source projects 2D dynamic image light. The second light source projects 3D dynamic multi-visual resultant image light. A parallax grating structure is arranged on the first image face. The surface of a shading assembly in the parallax grating structure is made of materials with light reflex and light scattering. A back projection screen structure is arranged on the second image face and is made of materials with light reflex and light scattering. The first image face and the second image face are respectively arranged on two faces of the transparent base material. In addition, by use of the method of respectively projecting the 2D dynamic image light and the 3D multi-visual resultant image light on the first image face and the second image face, an objective of simultaneously displaying the 2D dynamic image and the 3D dynamic image is achieved.

Description

technical field [0001] For the conventional 3D digital signage (3D Digital Signage), generally a view separation device composed of a lens array (Lenticular) is used to display a naked-view 3D dynamic image to achieve the purpose of providing 3D advertisements. The conventional 3D digital billboards are limited by the mass production technology and cost, generally only use a display with a small screen size and a fixed view separation device. The so-called fixed view separation device means that the view separation device does not have the function of switching between 2D and 3D images. Therefore, the conventional 3D digital billboard can only provide 3D-specific advertisements. The present invention proposes a method and device capable of displaying 2D and 3D dynamic images at the same time, so as to increase the image display function of conventional 3D digital billboards and greatly increase the benefits of advertising. Background technique [0002] Such as Figure 1~2 ...
