Conventional AC gas panels consist of two sets of conductors of equal widths arranged in orthogonal fashion on glass substrates covered with a dielectric material and separated by a gas-filled chamber. When appropriate electrical stimulation is applied, a plasma will form and emit light. The amount of light depends, among other things, on the width of the rear electrode. Usually the front and the rear electrodes are of equal width, resulting in uniform electrical characteristics, i.e., horizontal and vertical maximum sustain voltages. By designing the rear electrodes wider and the front electrodes thinner, but maintaining the same cross-sectional area at the intersections, the following benefits are realized.
