A method and system for implementing functions in a class that inherits an interface and that inherits an implementing class which implements the interface. The thermally conductive sheet has a top surface, a bottom surface and thickness therebetween defining an opening therethrough sized to receive therein the LED such that the thickness of the thermally energy dissipating medium defining the opening is in physical, thermally conductive contact with an exterior surface of the at least one side portion of the encapsulating material of the LED. The upper and lower planes contain the color or gray scale for the page as well as the continuous tone pictures that are contained on the page.
