More Information
Summary:The utility model provides a screen, include: the flat substrate, the reflection stratum, reflection stratum that the metal of going up the configuration for the face of the party through the substrate formed, on the face of the opposite side with substrate face in opposite directions, form a plurality of hair lines that extend in a direction and extend in the direction with a direction quadrature and short for the length of a direction of a plurality of hair lines a plurality of unsmooth, and surface diffusion layer, on one side of configuration face of opposite side in the reflection stratum, for visual light, optics isotropic and transparent, and it is unsmooth having on the surface of the opposite side with reflection stratum face in opposite directions, the reflection stratum has with the downwards angle of visibility characteristic, it is the proportion that luminous intensity when light struck white board in the white board is 1 the condition, peak gain as maximum value in the full visual angle is 6~14
