Abstract: The present disclosure relates to an image display apparatus and a method thereof. The image display apparatus according to an embodiment of the present disclosure comprises: a display; an external device interface including at least one communication module, the external device being configured to communicate with a remote control device using short-range communication; a memory; and a controller configured to: check a voltage value of a battery included in the remote control device based on data included in a control signal received from the remote control device; when the voltage value of the battery is less than a predetermined reference voltage value, store the voltage value of the battery in the memory, and output a first message for requesting battery replacement through the display; when the control signal includes data indicating that the battery is replaced, calculate a voltage difference between a voltage value stored in the memory and the voltage value included in the control signal; and when the voltage difference is less than a predetermined reference difference, determine that the replaced battery needs to be replaced.
