Abstract: 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.

Abstract: A display driving circuit operating in video mode is described. The display driving circuit includes an interface configured to receive, from an external source, sync signals and image data corresponding to each of a plurality of frames, a data processor configured to receive the image data from the interface and convert the image data, and a timing controller configured to generate internal control signals for driving a driver circuit based on the sync signals and the image data. The internal control signals are configured to be output only when the sync signals and signals corresponding to the image data are input simultaneously, and panel driving signals are configured to be output when the internal control signals are output.

Abstract: A display system includes a host processor and a display driver integrated circuit. The host processor includes a first thermal sensor. The display driver integrated circuit including a second thermal sensor that is different from the first thermal sensor. The host processor generates a first performance control signal indicating whether to increase or decrease performance of a display panel from first temperature information that is obtained from the first thermal sensor and second temperature information that is obtained from the second thermal sensor, and to output the first performance control signal. The display driver integrated circuit receives the first performance control signal from the host processor, and controls the display panel based on the first performance control signal to adjust the performance of the display panel.
