Orthographic projection black gate projection screen

Abstract

The invention discloses an orthographic projection black gate projection screen, comprising an imaging layer located in the middle, wherein one surface of the imaging layer is provided with vacuum-coated optical glass beads and an adhesive containing inorganic silicon powder; a transparent grid-shaped optical film layer, an anti-dazzle layer and a scratch-proof layer are arranged on the other surface of the imaging layer; the optical glass beads are arranged on the adhesive; the anti-dazzle layer and the scratch-proof layer are added into the production of the transparent grid-shaped optical film through corresponding materials; and the transparent grid-shaped optical film layer is of a linear prism structure with a triangular cross section, and is mainly used for absorbing light above a screen and reflecting light below the screen to achieve the purpose of light resistance. The orthographic projection black gate projection screen effectively absorbs ambient light and lamplight by using a multi-layer structure and materials, so that a picture presents high contrast and bright color, and the orthographic projection black-grid projection screen is excellent in optical performance, high in light resistance and good in visual effect.

Description

technical field [0001] The invention relates to the technical field of photoelectric projection production equipment, in particular to a front projection black grid projection screen. Background technique [0002] With the improvement of people's quality of life, many high-income families have upgraded their film and television, and then upgraded to the era of anti-light projection. However, many buyers of the anti-light curtain, a new form of projection product, have such a question: what is an anti-light curtain, and what advantages does it have compared to traditional projection screen products? The picture effect under interference can be used in the environment where the curtains are opened during the day and the lights are turned on at night, so that people can bid farewell to the dark viewing environment around them. The characteristics of the anti-light curtain are: through anti-light, filtering, and absorbing ambient light, the effect of enhancing picture contrast,...

AI Technical Summary

Problems solved by technology

When projecting, in order to reduce the influence of ambient light, it needs to be carried out in a dark environment. However, when the sunlight is strong, the ambient light will still enter the inverted projection screen from the periphery of the projection screen, affecting the quality of the image.
