APPARATUS AND METHOD FOR REDUCING PERCEIVED COLOR SHIFT

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and a method for reducing a perceived color shift. SOLUTION: An apparatus and a method for reducing perceived color shift as a function of a viewing angle is disclosed. One embodiment is a display device that includes a color light modulator and a color filter. The filter is configured to filter wavelengths of light that would be perceived as color shifted light when reflected by the modulator at an off-axis viewing angle. Another embodiment includes a color light modulator and a color light source configured to provide light having a spectral content that lacks the wavelengths that would be perceived as color shifted light by a view of the display at an off-axis viewing angle. Another embodiment is a method of making such display devices. COPYRIGHT: (C)2006,JPO&NCIPI
