Technical Field

The invention relates to the technical field of optical projection display, in particular to a scratch-resistant black grid screen.

Background

At present, screen display modes are mainly divided into two major types, one is electronic video display such as liquid crystal screen display, plasma screen display and the like, and the other is projection display to a screen by using a projector, and the latter is more widely applied along with the continuous promotion of new products of LCD projectors and the factor effects of easy installation and adjustment and low cost. However, such projection screens are susceptible to ambient light during the display process and can only be used in dark indoor environments, which greatly limits and hinders the development of screen display technologies using projectors and projection screens.

The black grid screen is distinguished by having a special optical structure and combining high-tech materials such as a black film grating capable of absorbing ambient light, a micro prism for controlling the direction of a light path and the like perfectly. The black film layer grating in the black grating screen adopts a horizontal shutter form, the gratings are arranged in a three-dimensional mode, the space ratio of the gratings is extremely small, projection light can pass through the gratings to the maximum extent, and therefore the brightness and the sharpness of contrast of images projected on the screen are extremely high. The color of the image projected on the special screen can be well restored, and the black grid layer can also remove the reflection of light on the surface of the screen, so that the image is more natural, soft and vivid. The projection effect of the black grid screen is inseparable from the abrasion degree of the black grid teeth, the abrasion resistance of the existing black grid screen is general, the service life of the screen is greatly reduced, and the projection effect is reduced.
