Abstract: An output buffer circuit is provided. The output buffer circuit includes a fast slew rate (FSR) controller that detects a transition duration of an input voltage, to adjust a magnitude of a detection current generated in the detected transition duration based on information on a slew slope, and to generate a slew rate control signal as the adjustment result, and an output buffer that outputs the input voltage as a source drive signal having a slew rate or a slew slope, which is selected, in response to the slew rate control signal.

Abstract: Provided are a source driver configured to drive a display panel and a display device including the same. A source driver configured to drive a source line of a display panel includes a digital circuit configured to receive and store digital pixel data, and an analog circuit configured to convert the stored digital pixel data into an analog-signal-type gradation voltage and output the analog-signal-type gradation voltage. A static current of the analog circuit is reduced in response to a value of a timing signal corresponding to a non-driving section of the display panel.

Abstract: The present invention disclosed herein relates to a system and method for providing a bidding service. A bidding service providing system according to an embodiment of the present invention may include a bidding condition determination unit configured to determine a maximum number of bidders and a bidding price on a basis of an equivalent value of a bid subject, a successful bidder selection unit configured to select a predetermined number of successful bidders from among bidders, and a repayment processing unit configured to set a credit-debt relation between the successful bidders and failed bidders and perform a process for repayment of debt to the failed bidders by the successful bidders.

Abstract: A power supply apparatus and a power supply method are disclosed. The power supply apparatus may include an internal power supply including a first voltage generator configured to generate a first voltage based on a pulse width modulation control signal, a charge pump configured to receive the first voltage and generate a second voltage, and an inrush current controller configured to be connected between the charge pump and the internal power supply and configured to generate the pulse width modulation control signal based on a target signal and a selection reference voltage.
