Abstract
Disclosed is an electronic device including a display panel, an oscillator generating a clock signal, a display driving integrated circuit (DDI) generating first time information, using the clock signal, a sensor, and at least one processor identifying a variable measured by using the sensor or second time information corresponding to a reference time. The at least one processor is configured to measure a variable, using the sensor, to correct an error time between the first time information and second time information corresponding to a reference time, based on the variable, and to deliver the corrected error time or the second time information to the DDI such that the DDI corrects the first time information based on the corrected error time to display a screen of the display panel. Besides, various embodiments as understood from the specification are also possible.
