An organic light emitting diode light source comprises a plurality of groups of OLEDs, the OLEDs in each group being electrically connected in parallel, and the groups being electrically connected in series. The storage materials are composed of vertical stacks of graphene sheets and have reduced resistance for Li ion transport. The insulating layer formed on the substrate covers the first and second polysilicon regions. The circuit includes a first parity processor. One first and one second central area are disposed between the main connection areas. A check valve is disposed in the orifice for allowing one-way flow of oil from the reservoir chamber to the high pressure chamber.
