    Abstract: An instruction of an electronic device is provided. The instruction of the electronic device, when executed by a processor, causes a display panel to be operated using one of a first gamma set corresponding to a first operating frequency and a second gamma set corresponding to a second operating frequency, each of the first gamma set and the second gamma set comprises gamma voltage values for each luminance and gradation, the first gamma set and the second gamma set include the same gamma voltage value in a first gradation range of a first luminance so as to have the substantially same optical characteristic when the operating frequency changes, the first gamma set and the second gamma set include the same gamma voltage value in a second gradation range of a second luminance, and the first gradation range and the second gradation range are different from each other.

    Abstract: An electronic device is provided. The electronic device includes a memory, a display driver integrated circuit (DDIC), a display, and a processor that generates an image frame, transmits the image frame to the DDIC, and controls the DDIC to drive the display based on the image frame. The DDIC outputs a first timing signal at a first frame period, outputs a second timing signal at a second frame period longer than the first frame period when the reception of the image frame is delayed, and outputs a third timing signal at a third frame period longer than the first frame period and shorter than the second frame period when the image frame is not received for a designated reference time after the second timing signal is output.

    Abstract: A display device including a display panel and a display driving circuit to control the display panel are provided. The display driving circuit includes a light emitting control driver to input a light emitting signal for controlling the brightness of the display panel into the display panel. When a light emitting control signal including a plurality of pulses is input into the light emitting control driver to control the light emitting signal, and when the operating frequency of the light emitting control signal is changed, pulse widths corresponding to at least two pulses of pulses included in the light emitting control signal may be adjusted to differ from each other in a frame after the target time point to change the operating frequency.

    Abstract: An electronic device includes a display including a plurality of regions, a display driver integrated circuit configured to drive a first region of the display at a first driving frequency and drive a second region of the display at a second driving frequency according to a configuration of the display, and a processor configured to provide display data to the display driver integrated circuit. The processor identifies a driving frequency of a first screen to be output on the display in response to reception of a first input; and controls the display to output at least a portion of the first screen on a region, of the plurality of regions, driven at a driving frequency corresponding to the driving frequency of the first screen. The display optimizes driving frequency, thus reducing heating problems and resource waste in the electronic device.
