The following describes each component of the light-resistant hard screen of the present embodiment in detail.
the light-resistant screen 1 is distinguished from a conventional projection screen, which is generally a diffuse reflection screen (including a white wall). It depends on the projector to project light on it, construct the image plane, it is a kind of passive imaging material; for a front projection screen, the image that we usually see is formed by reflecting light onto the retina. The light projected by the projector is a kind of energy, i.e., light energy. In the case of a diffuse reflection projection screen, light projected thereon is diffusely reflected 180 ° toward the space, and in the 180 ° space, only a small amount of light energy projected by the projector is received by the eyes, and most of the light is scattered into the space. Therefore, even in a completely dark room, the entire room is illuminated even though the picture is projected only on the screen after the projector is turned on. Some of the light scattered into the environment is reflected back to the screen and is superimposed on the image on the original screen, which reduces the contrast of the picture and changes the original color of the picture. The light-resistant curtain realizes light resistance through the optical coating and the physical structure, can absorb ambient light around, and can control the incident light of the projector to reflect to a visual angle area where human eyes are positioned, thereby reducing the projection light scattered into the space as much as possible. The utilization efficiency of light energy will improve greatly like this, and the projection light energy that eyes received is more, and the ambient light of interference reduces, and color, luminance, contrast all can be effectively promoted, consequently, anti light curtain effect will be better than ordinary diffuse reflection curtain far away. In this embodiment, the light-resisting curtain 1 is an ultra-short focus light-resisting curtain.
