Abstract
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.
