摘要：The surface structure (32) of a transparent film (30, 60, 84) recycles light (54, 70) that would exit an LCD display (82) at angles greater than 75° for brightness enhancement. The disclosed structures might not include small prisms (36, with a height of 5-20mum) with facets angled at about 90° but they all contain (large) prisms (38, with a height of 20-50mum) that feature a (rounded) peaks with facets (40,42) angled at about 96° and a base with facets (44, 46) angled at about 90°. The radius of curvature (rc) of a rounded peak is small (<10.5mum) to avoid undesirable brightness reduction.
