Patent attributes
An organic light-emitting display apparatus includes an organic light-emitting diode (“OLED”), a driving transistor including a gate connected to a first node, and which supplies driving current to the OLED according to a voltage of the gate, a storage capacitor which is connected to the first node, and maintains a voltage of the first node constant, a switching transistor connected to the first node, and comprising a pair of transistors which are turned on at a same time according to a first control signal, and serially connected to each other via a second node, and a voltage level changer which is connected to the second node, and changes a voltage level of the second node to a reference voltage level after the switching transistor is turned off.
