    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 processor. The electronic device includes a display including a display panel and a display driver circuit that includes memory. The display driver circuit is configured to identify an event for a display on the display panel. The display driver circuit is configured to, in response to the event of a first type that executes the display through the memory, change, at a timing before a reference time from a start timing of a scan for the display, a state of a signal provided from the display driver circuit to the processor from a first state indicating to enable an image transmission to the display driver circuit to a second state indicating to disable the image transmission. The display driver circuit is configured to, in response to the event of a second type that executes the display by bypassing the memory, change, at the start timing, the state of the signal provided from the display driver circuit to the processor from the first state to the second state.
