Claim 9:
10. A method of operating an image display apparatus including a rollable display panel wound or unwound from a roller, the method comprising:
detecting a temperature of a display panel of the image display apparatus based on a sensing value detected through a temperature sensor of the display apparatus;
in response to the temperature of the display panel being less than a reference temperature, applying a light emitting main signal to a first pixel group including some pixels of a first area of the display panel and a second pixel group including some pixels of a second area of the display panel; and
in response to the temperature of the display panel being equal to or greater than the reference temperature, controlling an operation of the roller to wind or unwind the display panel from the roller,
wherein the first area is first exposed to an outside of a housing of the image display apparatus before the second area when the display panel is rolled up.
