Projection curtain with optical structure

Abstract

The invention discloses a projection curtain with an optical structure. The projection curtain comprises a base material layer and an optical structure layer, wherein the optical structure layer of the projection curtain with the optical structure comprises a plurality of long-strip-shaped concave mirror structures arranged on a base material layer, the optical structure layer comprises a plurality of reflection structures and a plurality of light-transmitting structures, the reflection structures and the light-transmitting structures are arranged alternately and are all arranged on the base material layer, when light emitted by the projection equipment irradiates the projection curtain with the optical structure, the reflection structure reflects the light to converge the light, and the refraction structure can transmit ambient light, so that the ambient light is absorbed by the base material layer. The projection curtain with the optical structure is low in cost, can absorb ambient light, improves the brightness gain of the screen, maintains the original visual angle, and improves the image brightness of the curtain.

Description

technical field [0001] The invention relates to the field of projection screens, in particular to an optical structure projection screen. Background technique [0002] Early telephoto projection requires a distance of two to three meters to project a large screen of 100 inches. When we use it at home, we often need to hoist it. Therefore, we have to spend a lot of thought on the wiring and installation in the early stage, especially if The location of the projector was not reserved during the decoration, and it will be more troublesome to install the projector later. Not only is the cost high, but the wiring everywhere is also very unsightly. Therefore, in the past, users often sneered at home projection. The emergence of short-focus products has reduced the projection distance of home projection products to less than 2 meters. This distance allows home users to avoid the trouble of hoisting. The living room of more and more ordinary family users. When the products of ult...
