This paper is an analysis on the uniform luminance distribution and micro-pattern replication ratio through the measure of micro-patterns on the injection-molded light guide plate. In this study, we measured micro-patterns on the 40 inch LGP that has the different form of micro-patterns. We measured a uniform array density pattern (micro lenticular lenses) and a non-uniform density array pattern (micro dots). The injection-molded LGP was divided into 40 areas, and micro patterns on the each area were measured by various measurement equipment. Applying measured results to the optical simulation, we found that the uniform pattern has over 95% of the luminance uniformity and non-uniform pattern has over 80% of the luminance uniformity.
