Abstract:
A pixel is provided that has an internal compensation circuit capable of compensating for a threshold voltage of a driving transistor without loss of a data voltage and a light emitting display apparatus including the same. The pixel includes a light emitting device and a pixel circuit connected to the light emitting device. The pixel circuit includes a driving transistor including first and second gate electrodes, a source electrode, and a drain electrode, a first capacitor formed between the first gate electrode and the source electrode of the driving transistor, a second capacitor formed between the second gate electrode and the source electrode of the driving transistor, and a switching circuit connected to the first and second gate electrodes, the source electrode, and the drain electrode of the driving transistor and operating in order of a first to a fourth period.
