Homochromatic and Color Display Assembly on an Electronic Device and Method for Operation Thereof
First Claim
1. An electronic device comprising:
- a homochromatic liquid crystal display, a color liquid crystal display, and a backlight having a light-pipe;
the homochromatic liquid crystal display, the color liquid crystal display and the light-pipe being positioned in overlapping relation to each other, the light-pipe arranged to direct light through both the homochromatic liquid crystal display and the color liquid crystal display;
a homochromatic liquid crystal display driver arranged to generate an image on the homochromatic liquid crystal display in response to an image signal;
a color liquid crystal display driver arranged to generate an image on the color liquid crystal display in response to an image signal; and
a processor arranged to receive a light control signal, and to forward an image signal to one of the homochromatic liquid crystal display driver or the color liquid crystal display driver dependent on the light control signal.
