Problems solved by technology

However, since the size of the microstructure is very small, and the pitch is generally in the range of 25 to 250 microns, the process of selectively coating the optical functional layer on the surface of the microstructure is very complicated, the yield is low, and the optical efficiency is not high.

Abstract

The invention discloses a screen with a light-absorbing layer and a preparation method of a light-absorbing film used for the light-absorbing layer. The screen includes a first transparent substrate layer, an optical function layer, an adhesive glue layer and a light-absorbing layer that are sequentially stacked from the incident side of the projection light. The light absorbing layer receives and absorbs the light passing through the adhesive layer and reaching the light absorbing layer. The optical functional layer includes a plurality of microstructural units, the plurality of microstructural units form a sawtooth structure, and the optical functional layer enables at least part of the projected light to exit after total reflection and transmit at least part of the ambient light . According to the present invention, the screen gain can be improved while obtaining high contrast, and the processing technology can be simplified and the cost can be reduced.

Description

technical field [0001] The present invention relates to the field of projection screens, in particular, to a screen with a light-absorbing layer and a method for preparing a light-absorbing film for forming such a light-absorbing layer. Background technique [0002] In recent years, with the continuous improvement of the brightness of projectors, the advantages of projection display systems in large-scale home theater applications have begun to emerge. Compared with LCD TVs and OLED TVs, the projection display system is small in size, easy to install, and can easily realize a display screen larger than 100 inches, and the price of the whole system is relatively low. [0003] In a home application environment, a projection display system is often installed in a living room. The living room usually has good natural lighting conditions and bright lighting sources, so there is a lot of ambient stray light. A typical projector screen can reflect both the light from the projecto...
