1. An electronic device comprising:
a display panel;
a display driver IC (integrated circuit) configured to drive the display panel; and
a processor,
wherein the display driver IC is configured to:
set an output time of each line constituting the display panel to a first time period,
set a number of vertical blank lines for the display panel to a first number,
drive the display panel at a first refresh rate corresponding to the first time period and the first number of the vertical blank lines;
receive a control signal, for changing from the first refresh rate to a second refresh rate, from the processor; and
based on receiving the control signal, change the set output time to a second time period while the set number of vertical blank lines is maintained and change the set number of vertical blank lines to a second number while the set output time is maintained, and drive the display panel at the second refresh rate corresponding to the second time period and the second number of the vertical blank lines,
wherein the first time period is different from the second time period, and
wherein the first number is different from the second number.
