Abstract
Various devices and methods of lighting a display are disclosed. In one embodiment, for example, a display device includes a transmissive display configured to be illuminated through a back surface and a reflective display configured to be illuminated through a front surface. A light source is disposed with respect to the back of the transmissive display to illuminate the transmissive display through the back surface. A light pipe is disposed with respect to the light source to receive light from the light source and is configured to propagate the light such that this light provides front illumination of the reflective display.
