Abstract: A power management driver includes a boost converter, a plurality of regulators, a sequence controller, and an operation controller. The boost converter converts an input voltage to a source drive voltage for drive a source driver based on a drive enable signal. The regulators regulate the source drive voltage to generate a plurality of drive voltages. The regulators corresponding to a respective number of predetermined devices. The sequence controller controls the timing for providing the source drive voltage to the source driver. The operation controller adjusts active periods of first and second control signals to control the regulators and the sequence controller.

Abstract: A power supply device includes a voltage range selector, a voltage level controller, and a power supply voltage generator. The voltage range selector generates a range selection signal to select a voltage control range. The voltage level controller generates a voltage level control signal based on a driving condition of a display panel. The power supply voltage generator generates a power supply voltage having a voltage level corresponding to the voltage level control signal within the voltage control range, and supplies the power supply voltage to the display panel.

Abstract: There are provided a DC-DC converter and an organic light emitting display device using the same. A DC-DC converter includes a converting module and a sensing unit. The converting module includes a switching module and a control module. The switching module has a plurality of switches, and each of the plurality of switches converts an input voltage into a first voltage and outputs the first voltage while being turned on/off in response to a corresponding pulse width modulation (PWM) signal. The control module controls a switching operation of the switching module by generating the PWM signal. The sensing unit senses driving current supplied to a load to which the first voltage is provided.

Abstract: A panel packaging tray includes a packaging case including a sidewall which defines a receiving section in which a display panel is accommodated and a plurality of supports disposed on an inside surface of the sidewall, where the supports guide a position of the display panel on a plane crossing the inside surface. A supporter of the supports includes a fixing unit coupled with the sidewall and a buffer unit disposed between the fixing unit and the display panel. The buffer unit includes a straight portion, a corner portion, and a curved portion located between the straight portion and the corner portion, based on a direction parallel to the plane. A curvature of a curved surface included in the curved portion is determined by a maximum tilt angle by which the display panel is allowed to be tilted in a state of being accommodated in the receiving section.
