Systems, methods, and devices that generate a desired boosted gate voltage to facilitate controlling a charge pump are presented. The sensor is supported by a connector transmitting power to the electric motor. The workflow is displayed using icons representing the Boxes. The one or more sensors could include one or more microphones. With this operation, it is possible to carry out an optimal gamma compensation suitable to a characteristic of the color liquid crystal display and to remove a gradation batter occurring in a specific color.
