Holographic stereoscopic image projection device and its application and use method in electronic products

Abstract

Disclosed are a holographic reconstructing device and its application for portable electronic products. The holographic reconstructing device includes a compound hologram (9), a hologram seat (91), and a rebuilding light source (12). The compound hologram (9) is a flat-disk contour and disposed on the hologram seat (91). The rebuilding light source (12) is an LED and disposed under the hologram seat (91). The LED takes advantage of a small magnitude, less electricity consumption, simplified components, and a narrow bandwidth to definite a rebuilt image. The application of the flat-disk compound hologram is in a smooth-lying placement while reconstructing, which preferably occupies less space and facilitates user's observation as the rebuilt image is placed on the top of the compound hologram. The embedding of the holographic reconstructing device into the products would not affect the dimension of the products, thereby exhibiting realistic images on an individual space and forming a strong visual, clear impression, and a newly entertaining effect.

Description

technical field [0001] The present invention relates to an image projection device, in particular to a holographic stereoscopic image projection device and an electronic product using the device, a touch input device, an input method, and an electronic device equipped with a touch input device. Background technique [0002] As we all know, holography is a technology that uses the principle of light interference and diffraction to record and reproduce the light wavefront of an object. After continuous improvement and development of holography, people have developed a compound holography that can use ordinary light sources to project stereoscopic images. Composite holography combines the principle of rainbows with general photographic methods. Composite holography is a three-dimensional image technology that uses a laser light source to shoot objects in three-dimensional space. Repeated exposures are performed on the same film to record multiple images of objects from differen...

Problems solved by technology

[0006] Third, the composite holographic photo adopts conical and cylindrical composite holographic photos. When the image is projected, the conical and cylindrical composite holographic photos must be placed upright, which will easily cause the volume of the holographic stereoscopic image projection device to be large.

[0007] Fourth, the composite hologram adopts conical and cylindrical composite holograms, and the viewing angle is also affected. When people are below the image of the conical composite hologram or above or below the cylindrical composite hologram , cannot see the projected image
