The piezoelectric pump includes an actuator powered by an inductor coil integrated into the inflatable cylinder allowing for wireless control of the inflation and deflation of the inflatable cylinder. This drastically reduces the time it takes to determine the TFT gate voltage versus OLED current characteristics of the sub-pixels in the OLED display. The switch circuit is coupled to the transistor oscillating circuit for outputting a start signal to generate the original oscillating signal.
