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 low drop-out (LDO) regulator includes a pass transistor, a feedback circuit, an error amplifier, and a compensation unit. The pass transistor is configured to regulate a power supply and output an output voltage according to a control signal. The feedback circuit is configured to generate a feedback voltage based on the output voltage. The error amplifier is configured to output a comparison signal in response to a reference voltage and the feedback voltage. The compensation circuit is configured to generate a negative capacitance in association with a first node connected to a gate electrode of the pass transistor.
