Abstract:
The present disclosure relates to a display apparatus and a diving method thereof that can prevent a dark spot caused by a leakage of a reset voltage to the anode electrode of a light emitting diode. In the display apparatus, a first (anode) electrode of a light emitting diode EL, one electrode (a source or drain electrode) of an emission transistor T4, and one electrode (a source or drain electrode) of a reset transistor T6 connect to one another, and a fourth gate electrode of the emission transistor T4 and a sixth gate electrode of the reset transistor T6 connect to an emission control signal line EML, solving the problem of a dark spot, ensuring improvement in the quality and reliability of a product, and enabling a narrow bezel.
