LIGHT EMITTING DIODE DISPLAY

摘要

PURPOSE: A light emitting diode display is provided to the deterioration of a driving switching element by supplying a voltage having a reverse polarity to the gate electrode of the driving switching element periodically. CONSTITUTION: In a light emitting diode display, a plurality of pixel cells(PXL) comprises a light emitting diode. A plurality of data line(DL1-DLm) transmits a data signal having information about an image. A plurality of gate liens supplies gate high voltages having different level and a gate signal formed with the first gate low voltage, a second gate low voltage having a reverse polarity to data signal.
