Abstract
Subject matter disclosed herein relates to arrangements and techniques that provide for using a wavelength specific illumination for illuminating a display, for example an electrowetting display. The electrowetting display comprises a first substrate and a second substrate. A plurality of pixel regions is provided between the first substrate and the second substrate. The electrowetting display further comprises a first fluid within the pixel regions and on the first substrate. The first fluid comprises one or more dyes and a second fluid is disposed on the first fluid. The second fluid is substantially immiscible with the first fluid. An illumination layer is included between the first substrate and the second substrate. The illumination layer comprises one or more LEDs and at least one of the LEDs produces light at a specific wavelength corresponding to a wavelength of absorption of one of the one or more dyes.
