Design of polarizing color filters with double-liquid-crystal cells.
A method of designing polarization rotators with double-liquid-crystal (LC) cells is presented. When placed between a polarizer and an analyzer, the polarization rotator becomes a polarizing color filter. Any required color can be generated by optimization of the parameters of the double-LC layers. One specific example of a green filter is given. This filter is analyzed in terms of the optical performance, including transmission spectrum, color coordinates, and viewing angle. A sample green polarizing color filter was made and compared with the theoretical results.
