Using Surface-Plasmon Filters To Generate Scrolling Colors

Surface-plasmon tunable filters (SPTFs) have been proposed for use in generating scrolling colors on the faces of liquid-crystal display (LCD) devices. In comparison with a conventional color LCD device equipped with primary-color filters, a LCD device equipped with SPTFs according to the proposal would utilize a greater proportion of the available luminous flux, generating a display about six times as bright, eliminate the in-pixel dye color filters, and cut number of pixels to one third.
