摘要： The present invention provides a composite light guide plate having a thickness of more than about 1 mm, for use in LCD backlights or in general illumination devices. In the fabrication method of the present invention the extrusion roll molding process is combined with coating and lamination steps to enable a cost effective roll-to-roll or roll-to-sheet manufacture of the thick composite light guide plate wherein one or both principal surfaces of the light guide plate contain a pattern to enable extraction and redirection of light by the light guide plate from a light source or multiple light sources placed at one or multiple edges of the light guide plate. The composite light guide plate comprises a patterned film and a pre-cut sheet joined together by an adhesive layer. In order to attain good light extraction efficiency the adhesive layer and the two constituent layers of the light guide plate must be optically matched such that the refractive indices of any two of the three materials of the composite light guide plate can differ by no more than 0.01.

摘要： A light-guiding article has a film substrate that has at least one patterned surface having a plurality of discrete surface features and an incident edge that is substantially orthogonal to the at least one patterned surface. Each surface feature in the plurality of discrete surface features extends along a length direction that is substantially parallel to the incident edge. Taken in cross-section along the length direction, each surface feature has a positively sloped portion, a substantially flat portion, and a negatively sloped portion. A first widthwise cross-section taken at a first position through the positively sloped portion has the same shape as a second widthwise cross-section taken at a second position through the negatively sloped portion.
