Methods and apparatus for adjusting the operation of a display device so as to be at least within prescribed form factor or other constraints. The insulating member has a thickness between the first and second electrodes near the top side of the first electrode and the top side of the second electrode. The rotor is rotatably installed in the casing. Mixture that is not broken down is recycled back to the bottom of the vertical cavity by a fan while the resultant hydrogen and carbon dioxide is allowed to rise to a trap that separates the hydrogen from the carbon dioxide. A process for forming the electronic device is also described.
