Problems solved by technology

[0004] However, due to the certain thickness of the projection screen, the image projected on one side (such as the front side) of the projection screen will be reflected on the front and back surfaces of the projection screen respectively, so that the user can observe two reflection images, thus causing heavy shadow phenomenon, resulting in poor projection display effect

Embodiment Construction

[0031] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present application as recited in the appended claims.

[0032] Traditional projection display can only image on one side, and the image information presented on the projection screen can only show one-sided image. With the gradual improvement of users' expectations for viewing experience, many projection equipment manufacturers have launched projection products that superimpose the front and back information of the displayed image and present...

Abstract

The invention relates to a projection screen, and relates to the technical field of optics. The projection screen comprises a light-transmitting base material and a plurality of light reflecting components. The plurality of light reflecting components are attached to the front surface and the back surface of the light-transmitting base material in a discrete manner, and the light reflecting assembly comprises a reflecting layer attached to the light-transmitting base material and a light diffusion layer wrapping the reflecting layer. By means of the light reflecting components, the reflectionintensity of the near surface (namely the surface of the side, close to the projection source, of the projection screen) is enhanced, and the reflection intensity of the far surface (namely the surface of the side, away from the projection source, of the projection screen) is restrained, thereby reducing the ghosting phenomenon under the condition that the projection screen is perspective, and improving the display effect of projection.

Description

technical field [0001] The present application relates to the field of optical technology, in particular to a projection screen and a projection system for double-sided projection. Background technique [0002] With the gradual improvement of users' expectations for viewing experience of projected images, many users expect to be able to watch a relatively three-dimensional projection effect. [0003] A projection system capable of projecting on both front and back sides is proposed in the related art. The projection screen of the projection system is made of light-transmitting material, and the user on one side of the projection screen can observe the scene on the other side of the projection screen through the projection screen. When the projection system works, different images are projected on the front and back sides of the projection screen, for example, the front image of a person is projected on the front of the projection screen, and the back image of the person is ...
