1. An image display apparatus, comprising:
a housing;
a roller disposed within the housing;
a display panel including a plurality of pixels and wound on or unwound from the roller;
a temperature sensor configured to detect a temperature of the display panel; and
a processor configured to:
check the temperature of the display panel based on a sensing value detected through the temperature sensor,
in response to the temperature of the display panel being less than a reference temperature, apply 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, control 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 the housing before the second area when the display panel is rolled up.
