Light-emitting display apparatus and driving method thereof

A light-emitting display apparatus, comprising:

• a light-emitting element including a parasitic capacitance, the light-emitting element to emit light having a gray scale value based on a supplied current;
• a first transistor to control a magnitude of current to be supplied to the light-emitting element, and having a first terminal connected to one terminal of the light-emitting element;
• a second transistor connected between a gate electrode of the first transistor and a first power supply;
• a third transistor having a first terminal connected to the gate electrode of the first transistor and a second terminal connected to a second terminal of the first transistor via a capacitive element;
• a fourth transistor connected between the second terminal of the first transistor and a second power supply;
• and
• a fifth transistor connected between the second terminal of the third transistor and a signal line to receive an initialization voltage and a gray scale data voltage.

A pixel, comprising:

• a first transistor to control a magnitude of current to be supplied to a light-emitting element;
• a second transistor connected between a gate electrode of the first transistor and a first power supply;
• a third transistor connected between the gate electrode of the first transistor and a second terminal of the first transistor;
• a capacitor coupled between the third transistor and the second terminal of the first transistor;
• a fourth transistor connected between the second terminal of the first transistor and a second power supply;
• and
• a fifth transistor connected between the second terminal of the third transistor and a signal line, wherein the capacitor is the only capacitor in the pixel and wherein the signal line is to receive an initialization voltage and a gray scale data voltage.
