摘要:
A Fresnel projection screen includes: a Fresnel layer; a first micro-structure layer disposed at a light incident side of the Fresnel layer, the first micro-structure layer including a plurality of micro-structures that are configured to diffusely reflect a portion of light incident thereon and refract another portion of the light; a second micro-structure layer disposed on a surface of the first micro-structure layer, the second micro-structure layer including a plurality of second micro-structures that are configured to diffusely reflect a portion of light incident thereon and refract another portion of the light; and a reflective layer disposed on a side of the Fresnel layer away from the first micro-structure layer.
