In one embodiment, the control integrated circuit includes a gate driver configured to selectively drive a plurality of gate lines associated with pixels in a display panel; a source driver configured to supply data to the display panel; and a controller configured to generate switch control signals for controlling a switch driver of the display panel, the switch driver for selectively supplying the data to a plurality of data lines. The controller is configured to control the gate driver and generate the switch control signals such that the plurality of gate lines are activated non-sequentially, and an order of pixels activated and associated with a same one of the plurality of data lines includes at least two pixels of a same color activated in sequence.

Display panel, display device, and operation method of display device

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.

Display panel and a driving module of the display panel

A display driver integrated circuit is provided. The display driver integrated circuit includes a source driver configured to receive a power voltage from a power management integrated circuit and a logic circuit configured to control the power management integrated circuit. Display data or a command from an application processor is received, and the display data or the command is analyzed. A voltage level of the power voltage is controlled based on the analysis.

Display driver integrated circuit

Provided is a boosting circuit. The boosting circuit includes a voltage generator, a booster, a voltage detector, and a selector. The voltage generator receives an external first voltage to output a second voltage. The booster boosts an input voltage to output a third voltage. The voltage detector detects at least one voltage level of the first to third voltages to output a selection signal. The selector transfers one of the first and second voltages as the input voltage of the booster in response to the selection signal.
