Has been focusing on the development and production of Fresnel lenses
Yuying Fresnel Laser TV Screen
The Yuying Black Grating Laser TV screen is on the surface of the black grid screen. It is covered with a very small prism structure in the horizontal direction. Its function is to absorb and not reflect the light from the top of the screen, mainly from the light below the screen. The purpose of light resistance: The principle is to use a special process to make a screen with a zigzag cross section. While absorbing the interference light , it reflects the projection light. The white bevel is the reflective layer . The projector's light is projected from the bottom to the white reflective layer and then reflected into our eyes. The
interference light from above is black parallel. The layer is absorbed.
