Abstract
A pixel compensating circuit comprises an organic light-emitting diode (OLED), a first transistor, a compensating transistor, a storage capacitor, a second transistor, a third transistor, and a seventh transistor. If a present-stage scan signal is at a low voltage potential, the second transistor is turned on, the gate of the first transistor and the drain of the first transistor are short-circuited. A data signal is transmitted to a source of the first transistor after the third transistor is turned on. A third reference voltage is transmitted to the source of the first transistor after the seventh transistor is turned on. An aging phenomenon and the uniformity of the driving transistor are improved.
