摘要:
The present invention provides a light guide plate having an input surface for receiving light from a light source, a micro-patterned output surface for emitting light, and a micro-patterned bottom surface opposing to the output surface, made in steps comprising: extruding a resin into the nip between a pressure roller and a patterned roller to form a layer at a patterned roller surface temperature T1 and a nip pressure P1, the layer having an un-patterned surface and a patterned surface, the patterned surface having a pattern transferred from the patterned roller. Printing a discrete pattern on the un-patterned surface of the layer to form an optical sheet comprising a plurality of light guide plate patterns, and cutting and finishing the said optical sheet into a plurality of double-sided light guide plates having the specified length and width dimensions.
