For the LED back-lighted LCD panels with rapid injection-compression molded large optical parts in development, micro pattern transcription ratio of the molded shape to the original design was studied. Prismatic and hemispherical shapes were considered as micro patterns, and the transcription ratios were defined. The brightness uniformity of the whole back-light unit was optically simulated according to the ratio. And, the robustness of the brightness due to the molded micro patterns was predicted.
