technical field

The utility model relates to the technical field of projection screens, in particular to an anti-glare projection screen.

Background technique

With the advent of the information age, projection screens are widely used in various display occasions, mainly in conference rooms, command and control centers, training and education structures, exhibition halls and other occasions. When traditional projection screens are used, images are usually projected onto white plastic screens, gray screens, etc. The stronger the ambient light is, the higher the brightness of the projected image will be, and the contrast of the projected image will be severely reduced, resulting in a serious decline in imaging quality, which will cause the viewer to see clearly and lose the basic presentation effect. In addition, the current screen cannot be rolled up, which is inconvenient to carry, resulting in the disadvantage of low image quality. At present, most projection screens on the market cannot overcome these problems, and the market urgently needs a projection screen that can resist the interference of ambient light on the imaging picture. To this end, we propose an anti-glare projection screen.

In order to achieve the above purpose, the utility model provides the following technical solutions: an anti-glare projection screen, including a screen substrate, the right side of the screen substrate is provided with a reflective coating, and the inner cavity of the reflective coating is provided with a black glass The right side of the reflective coating is provided with a substrate layer, and the right side of the substrate layer is respectively fixedly connected with a light-absorbing layer and an imaging layer, and the light-absorbing layer and the imaging layer are respectively divided into several, and the adjacent light-absorbing layer A sawtooth structure is formed with the imaging layer, and the light absorption layer and the imaging layer form a sawtooth structure and are respectively located on the right side of the substrate layer.

Preferably, the microstructure of the black glass beads is irregularly arranged hollow spheres.

Preferably, the projection screen has a thickness of 0.5-0.8 cm.

Preferably, a layer of brightness enhancing matte film is arranged between the screen substrate and the reflective coating.

Preferably, the light-absorbing layer is perpendicular to the substrate layer, and the height of the light-absorbing layer relative to the substrate layer is 150-250 mm.

Preferably, the included angle between the imaging layer and the substrate layer is 32-45 degrees, and the imaging layer is arranged obliquely upward relative to the substrate layer.

Compared with the prior art, the utility model has the beneficial effects that: the projection screen contains a reflective coating, which can reflect light in a direction, and also contains black glass beads and a light-absorbing layer, so that good pictures can be obtained in a brighter environment, thereby Make the image more soft and natural. The surface of the light-absorbing layer is black, which can absorb ambient light, thereby improving the contrast of the projection screen. The imaging layer reflects the light of the projection screen image and restores the real projection screen. The substrate is highly elastic and tear-resistant High-quality polymer materials, so the screen can be rolled up as a whole, and it is more convenient to install and carry.
