Abstract: A display driving integrated circuit performs an adaptive frame operation. An operation method of the display driving integrated circuit includes outputting current frame data to an external display panel, starting to receive next frame data from an external device after a first time point, the first time point being a time point when a first time period elapses, the first time period immediately following a second time point at which the current frame data are completely output, and generating a vertical synchronization signal at a third time point synchronized with a cycle of an emission control signal, in response to starting to receive the next frame data.

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.
