Abstract: An electronic device configured to configure brightness of a display by using an illuminance sensor is provided. The electronic device includes acquiring a second front-surface sensing value smaller than a first front-surface sensing value through a first illuminance sensor while the brightness is a first brightness, comparing the second front-surface sensing value with a first rear-surface sensing value detected through a second illuminance sensor, determining, when the second front-surface sensing value is greater than the first rear-surface sensing value, whether a touch input is detected through a designated region of the display, maintaining the brightness at the first brightness when the touch input is detected, and when the touch input is not detected, adjusting the brightness of the display to a value lower than that of the first brightness, based on a first LUT stored in a memory, or maintaining the brightness of the display at the first brightness.

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: An example electronic device includes a display panel configured to display a screen, a display driver IC (DDI) configured to supply a data voltage for displaying the screen to the display panel, and a processor configured to transmit image data for setting the data voltage to the DDI. The DDI is configured to generate a synchronization signal for controlling a time point at which the data voltage is supplied to the display panel, and to deliver the synchronization signal to the processor. The processor is configured to select a time point, at which the image data starts to be transmitted, within a waiting period of the synchronization signal.
