Low voltage high efficiency illuminated display having capacitive coupled electrodes

摘要

A gas filled channel is formed between a pair of plates. A phosphor is disposed upon a surface of the channel and the channel is filled with a mixture of noble gases. A surface electrode is formed upon the exterior surface of each of the plates. Upon application of an alternating voltage to the pair of surface electrodes, the electrodes are capacitively coupled across the channel and break down the gas contained in the channel. The gasses emit ultraviolet light that causes the phosphor to emit visible light in a characteristic color.
