Abstract
Recently, at many LCD-related makers, the ray-tracing simulator for lighting analysis is being used to develop light guide plates and optical sheets, which are the parts of a backlight unit. As a result, the effective functions for LCD development, such as a polarization analysis function and a thin film coating function, have been incorporated in the ray-tracing simulator. This paper introduces the example that utilized ray-tracing simulation for lighting analysis in development of backlight units.
