Optical sheet manufactured with patterned rollers |
摘要 |
The present invention provides an optical sheet (300e) having a plurality of light guide plates patterns, each light guide plate pattern having a micro-patterned output surface for emitting light, and a micro-patterned bottom surface opposing to the output surface. The optical sheet is made in steps comprising: extruding a resin (450a) into the nip between a first patterned roller (480a) and a second patterned roller (480b) at a first patterned roller surface temperature T1, a second patterned roller temperature T2, and a nip pressure P1, to form the optical sheet, the optical sheet having a first patterned surface and a second patterned surface, the first patterned surface having a micro-pattern transferred from the first patterned roller and the second patterned surface having a micro-pattern transferred from the second patterned roller. |
