Abstract

The invention discloses a grey glass bead screen surface. The curtain surface comprises a screen base, a PVC black layer formed on one surface of the screen base and a PVC matte grey layer formed on the other surface of the screen base. The PVC matte grey layer is embedded with a microbead. The microbead is convexly stretched out of a surface of the PVC matte grey layer. A function layer covers asurface of the microbead. The function layer is made of one or more of an ultraviolet light blocking agent, a waterproof agent, a hydrophilc agent and a glass film coating agent. In the invention, thescreen surface reaches 2.2 gain brightness, screen brightness can be increased, simultaneously an optimum film watching angle can be reached; under the condition of a same screen size, a cinema can select a low brightness projector; and a film watching effect is guaranteed, simultaneously bulb energy consumption of the projector and a replacing frequency are reduced.

Description

technical field [0001] The present application relates to a projection screen, in particular to a gray glass bead screen. Background technique [0002] At present, projection technology is used in small mobile business presentations, multimedia conference rooms, classrooms, stadiums, churches, commercial places, large auditoriums, virtual displays and even super-large screens as large as movie theaters. Simply put, projection technology is to project the light from the projector onto the projection screen, form an image on the projection screen, and then reflect the light to the human eye. If the projection screen is properly matched with the projector, high-quality projection effects can be obtained. [0003] Projection screens can be generally divided into reflective and transmissive types in terms of function; reflective type is used for front projection, and transmissive type is used for rear projection; front projection screens are divided into flat screens and arc scr...
