Rear projection screen

Abstract

The invention relates to a rear projection screen which is obtained from performing burdening, stirring, plastic mixing, plasticizing and film production on raw materials, wherein the raw materials can be PVC resin, extinction PVC resin, plasticizer, organic flame-retarded oil, inorganic flame retardants, antioxidant heat stabilizer, light stabilizer, calcium carbonate, powder stabilizer and plasticizing accelerator. The rear projection screen overcomes multiple disadvantages of the traditional screen project material; when the screen is in use, light beams come from the rear to ensure that the front has the optimal viewing effect, the diffuse reflection and photopermeability of optical lines achieve excellent effects through embossing and controlling the material ratio, and colors are clear and saturated, therefore, the screen has the display effect of a liquid crystal display, and a user can not feel fatigue after long-time viewing; the screen does not reflect light, thus satisfyingaudiences to obtain good viewing effect within a plane angle of 180 degrees; and the light beams can be conveniently fused and spliced so as to achieve the requirement of greater projection effect.

Description

technical field [0001] The invention relates to a rear projection projection screen. Background technique [0002] With the continuous progress and development of society, the requirements for industries such as education, culture and sports, film and television, and media are getting higher and higher. In addition to the basic functional requirements of the product, it has gradually paid attention to the functionalization and humanization of the product, and increased the pursuit of environmental protection, energy saving, health and other aspects. [0003] The traditional projection materials are all front-projection, which is made of mesh cloth in the middle. The disadvantages are: [0004] 1. It is easy to reflect light, the image cannot be natural and clear, and it is easy to fatigue when watching; [0005] 2. The diffuse reflection effect is poor, and generally only has an ornamental effect within an angle of 45°; [0006] 3. The screen cannot be spliced, and the wi...
