Abstract
Methods for measuring power consumption include providing an assembly with electronic display subassemblies at a housing. The subassemblies each include light sources behind or adjacent to an electronic display layer and electricity consuming components. A simulated electric meter is electrically interposed between a utility electric supply and the electricity consuming components. The simulated electric meter includes a processor, an electronic storage device, and a current sensor. The assembly is operated. Current measurements are taken at the simulated electric meter. The power consumed is determined by multiplying each of the one or more current measurements with a predetermined amount or measurements from a voltage sensor to determine one or more power consumption measures.
