A display device is provided. The display device includes: a pixel array including pixels connected to gate lines and source lines; and a driving circuit configured to: apply gate signals to the gate lines and provide data signals to the source lines during a first scan period such that horizontal periods of the gate signals do not overlap each other, and apply the gate signals to first gate lines, of the gate lines, connected to pixels in a first area of the pixel array in a different manner from second gate lines, of the gate lines, connected to pixels in a second area of the pixel array for a portion of a second scan period, provide the data signals to the source lines, and maintain a low-biased state or an off state for a remaining portion of the second scan period.

Display device and driving method thereof

An operating method of a display driver integrated circuit (DDI) includes determining whether a change to a level of a first logic voltage supplied to a logic circuit of the DDI is required, based on determining that a change to the level of the first logic voltage is required, transmitting a logic voltage setting command to a power management integrated circuit (PMIC), and receiving, from the PMIC, a second logic voltage having a level different from the first logic voltage and corresponding to the logic voltage setting command.

Method of operating display driver integrated circuit, power management integrated circuit and electronic device including the same, and method of operating the same

Disclosed is a power module which includes a first power module that generates a first output current based on a first input voltage, a second power module that generates a second output voltage based on a second input voltage, generates a second output current based on the second output voltage, and generates the second output current when a level of the first input voltage is smaller than a level of a reference voltage, and a voltage controller that generates a feedback signal for regulating at least one of the level of the first input voltage and a level of the second input voltage based on current information about a current flowing in the power module.

Power module and electronic device therewith

A display panel includes a display module including a plurality of pixels connected to gate lines and source lines and a driver module configured to apply driving voltages to the gate lines and the source lines. The driver module includes a driving voltage generator configured to generate the driving voltages and a calibration circuit configured to compare each of the driving voltages with a reference voltage and to output a calibration parameter according to a comparison result. The driving voltage generator calibrates each of the driving voltages using the calibration parameter.
