    Abstract: The present invention provides a novel structure of picture elements in current programming-type semiconductor devices, and in particular, the structure of picture elements of an active matrix organic light emitting diode (OLED) display. The device makes a self-compensation for OLED current deviations due to the deterioration in threshold voltage and uneven electric characteristic in thin film transistors. The invention also provides a method for driving a data driver capable of compensating for the uneven electric characteristic of thin film transistors in the driver for driving picture elements in the current programming-type active matrix OLED display device.

    Abstract: In a DC-DC converting circuit, a charge pumping part receives an input voltage, a first clock and a second clock and outputs first and second voltages to first and second nodes, which are boosted by high voltages of the first and second clocks with respect to the input voltage. An output part is connected to the first and second nodes of the charge pumping part, and a level boosting part turns on or turns off the charge pumping part in response to the first and second clocks. The output part outputs the first and second voltages through an output terminal during a high period of the first clock and during a high period of the second clock, respectively. Thus, an output voltage having a voltage level corresponding to two times that of the input voltage may be output from the output terminal while the first and second clocks are provided.
