- The design of BLU for LCD devices, whose goal is to achieve uniform illumination and high luminance across the LCD surface, requries an assistance of illumination design programs. The goal of this paper is to develop a design and analysis tool to model an efficient BLU. The rendering techniques traditionally used in the field of computer graphics are the usual tools of choice to analyze BLU. An analysis method based on Monte Carlo photon tracing to evaluate the optical performance of BLU is presented. An optimization technique based on direct search method, a simplex method by Nelder and Mead, to achieve an optimal uniform illumination is also discussed.
