Classification: CPC G | IPC G

Claim 15:
16. An electronic device comprising:
a display panel;
a display driving integrated circuit (IC) configured to drive the display panel; and
a processor configured to control the display driving IC,
wherein the processor is configured to:
operate at a first driving frequency based on a first brightness and a first gamma set and operate based on a second gamma set in response to a change of the first driving frequency being requested, and
operate at the first driving frequency based on a second brightness and a third gamma set and operate based on a fourth gamma set in response to the change of the first driving frequency being requested,

wherein the second gamma set includes a second grayscale group having a gamma voltage value equal to that of some first grayscale groups of the first gamma set,
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 a second driving frequency,
wherein the fourth gamma set includes a fourth grayscale group having a gamma voltage value equal to those of some third grayscale groups of the third gamma set, and
wherein a number of grayscales of the second grayscale group is different from a number of grayscales of the fourth grayscale group.
