More Information
Summary:A reflective color display pixel has a top surface for receiving ambient light, and a plurality of sub-pixels including a first sub-pixel. The first sub-pixel has a broadband mirror and a luminescent layer disposed over the broadband mirror. The luminescent layer contains a luminescent material for absorbing a portion of the ambient light and emitting light of a first color, and a light-absorbing material for absorbing light of wavelengths longer than a wavelength of the first color.
