Abstract

The invention provides an imaging structure, a projection screen and a projection system, which relate to the technical field of imaging. Wherein the imaging structure includes a plurality of diffusion layers arranged in sequence in the thickness direction, and each diffusion layer has at least one surface in the thickness direction that is a non-smooth surface so that the light beam entering thediffusion layer of the layer can be diffused based on the corresponding non-smooth surface. With the above arrangement, the problem that the imaging effect is poor due to the poor diffusion effect ofthe light beam in the existing imaging structure can be improved.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to an imaging structure, a projection screen and a projection system. Background technique [0002] With the continuous development of screen display technology, projection has been widely used as a simple and convenient display method, for example, family entertainment or office needs. Among them, when displaying by projection, an indispensable device is a projection screen. Moreover, the imaging structure plays an important role as a key structure of imaging display in the projection screen. [0003] The inventors have found through research that, in the existing projection screens, since the light beam output by the projector diffuses poorly in the structure when it is transmitted to the imaging structure, there is a problem that the imaging effect of the imaging structure is poor Contents of the invention [0004] In view of this, the object of the present invention is to p...
