1. An electronic device comprising:
a display panel;
a display driving integrated circuit (IC); and
a processor configured to:
transmit image data to the display driving IC such that the image data is displayed on the display panel,
instruct the display driving IC to drive at one of a first driving frequency or a second driving frequency, and
drive a screen, which corresponds to the image data, with a set brightness,
wherein the display driving IC is configured to:
drive the display panel with at least one driving frequency of among the first driving frequency and the second driving frequency; and
under an instruction of the processor, drive the display panel by using one of a first gamma set corresponding to the first driving frequency or a second gamma set corresponding to the second driving frequency,
wherein the first gamma set and the second gamma set include gamma voltage values for each brightness and each grayscale,
wherein the first gamma set and the second gamma set further include equal gamma voltage values in a first grayscale range of a first brightness; and equal gamma voltage values in a second grayscale range of a second brightness, such that a substantially same optical characteristic is shown when a driving frequency changes,
wherein gamma voltage values of grayscale 255 of the first gamma set and the second gamma set are substantially equal to each other at the first driving frequency and the second driving frequency, and
wherein the first grayscale range is different from the second grayscale range.
