Abstract: A visible-light-photocatalyzed composite light-transmitting concrete contains several bundles of optical fibers, the optical fibers are coated with a protective layer on their outer surface, the protective layer contains a visible light photocatalyst, and the concrete has several gas-permeable pores. Such concrete is prepared by mixing a visible light photocatalyst and a light-transmitting glue, applying the mixture to the surface of optical fibers to form a protective layer, and using optical fibers in the concrete. The resulting concrete has dual properties of light transmittance and photocatalytic oxidation of gas-phase pollutants under visible light irradiation. The visible-light-photocatalyzed composite light-transmitting concrete significantly breaks through the limitation of photocatalytic concrete to light sources, so that gas-phase pollutants can be removed under visible light irradiation through photocatalysis of light-transmitting concrete.

Abstract: The present disclosure provides a display screen shell and a display screen. In the present disclosure, a display panel is disposed on a first flexible pad by disposing the first flexible pad on a middle frame. A tempered glass is disposed on a second flexible pad by disposing the second flexible pad on the middle frame. Elastic force of the flexible pads makes the display panel and the tempered glass assemble together, so that there is no gap between the tempered glass and the display panel, and a 0-distance-attaching is realized. The tempered glass and a liquid crystal display (LCD) screen are pressed together at an edge by pressing on the tempered glass of the pressing portion, making the tempered glass and the display panel attached together effectively for a long time, and no gap is created at an attaching place and extremely small parallax is achieved, no hollowing feeling in an effect of writing, making writing experience and visual experience optimal.
