Approach to analytically minimize the LCD moire by image-based particle swarm optimization

Abstract

In this paper, we proposed a methodology to optimize the parametric window of a liquid crystal display (LCD) system, whose visual performance was deteriorated by the pixel moire arising in between multiple periodic structures. Conventional analysis and minimization of moire patterns are limited by few parameters. With the proposed image-based particle swarm optimization (PSO), we enable a multivariable optimization at the same time. A series of experiments was conducted to validate the methodology. Due to its versatility, the proposed technique will certainly have a promising impact on the fast optimization in LCD design with more complex configuration. (C) 2015 Optical Society of America
