Design of optical filters for three primary colors

In order to obtain high-quality three primary colors to realize large color gamut display. Red,green and blue F-P filters were designed by means of transfer matrix method in optical thin film technology. Then these filters were put together to obtain a new filter allowing three primary colors to pass through and reflect other stray colors. The filter can satisfy the design target well. With this filter,color display function of displayer can be enhanced drastically.
