摘要:
The present disclosure relates to a light emitting diode display device which can prevent a drive switching device from degrading. The light emitting diode display device includes a plurality of pixel cells each having a light emitting diode, a plurality of data lines for transmission of data signal having information on a picture, a plurality of gate lines for transmission of a gate signal having a gate high voltage, a first gate low voltage, and a second gate low voltage having a polarity opposite to the data signal, wherein the gate high voltage, the first gate low voltage and the second gate low voltage having potentials different from one another wherein each of the pixel cells includes a signal transmission switching device for connecting the data line to a node according to the first gate high voltage from the gate line, a drive switching device for controlling an intensity of a drive current being supplied to the light emitting diode according to a signal state of the node, a storage capacitor connected between the node and a source electrode or a drain electrode of the drive switching device, and a control switching device for connecting the gate line to the node in response to the second gate low voltage from the gate line and a control signal from a control line.
