Abstract
An organic light emitting display apparatus according to an embodiment includes a thermal sensor configured to sense temperature and a controller including a first leakage current compensation unit configured to supply a first compensation signal to a plurality of sub-pixels based on the sensed temperature from the thermal sensor and a second leakage current compensation unit configured to supply a second compensation signal, which is different from the first compensation signal, wherein the controller compensates an amount of leakage current of the plurality of sub-pixels according to the sensed temperature.
