LENS UNIT AND PROJECTION SCREEN MADE OF THE SAME |
摘要 |
A lens unit and a projection screen made of the same are disclosed. The lens unit includes a micro lens having a light incident surface and a light emergent surface opposing to the light incident surface; a light absorbing layer formed on the light emergent surface of the micro lens and having a cavity formed therein; a scattering layer formed in the cavity of the light absorbing layer and including a transparent resin blended with scattering particles; and a reflective layer formed on the light absorbing layer and the scattering layer. The projection screen includes a plurality of the lens units, thereby achieving high contrast and high energy utilization efficiency of incident light with a large viewing angle.
