A novel geometry for electroluminescent devices, which does not require transparent electrodes electrical input, is demonstrated, theoretically analyzed, and experimentally characterized. Instead of emitting light through a conventional electrode, emission occurs polar liquid or solid input are coplanar, rather than stacked in sandwich configuration. This new device concept scalable easily deployed range modular alternating-current-powered sources light-emitting sensing devices. The polar-electrode-bridged displays can be used as remotely readable, spatially responsive sensors that emit response to the accumulation distribution materials on surface. Using this structure, various types alternating current devices demonstrated. These include an umbrella automatically lights up when it rains, display emits from regions touched by human fingers (or painted upon using mixture oil water), sensor differently different areas indicate presence water its freezing. study extends dual-stack, coplanar-electrode provide figure drawn panel graphite pencil.
