Abstract
The disclosure proposes the use of a graphical background for liquid crystal display assemblies. Two-dimensional graphics are printed on a rear surface of a liquid crystal matrix, a front surface of a lightguide, or a transparent label interposed between the liquid crystal matrix and the lightguide. Alternatively, three-dimensional graphics are covered or molded into a front surface of a lightguide used in the liquid crystal display assembly.
