Abstract:
1. An organic light-emitting diode display device, comprising: a display panel formed with pixels connected to at least a first and a second line; a timing controller comprising a mode selector configured to output a selection signal defining a first and a second drive mode; a power unit configured to supply a first and a second voltage; and a data driving unit configured to output the first voltage and a data voltage to the first and the second line, respectively, when the device is in the first drive mode, and output the second voltage and first voltage to the first and the second line, respectively, when the device is in the second drive mode, wherein the data driving unit comprises an output control circuit configured to selectively output at least two of the data voltage, first voltage and second voltage through the first and the second line in response to the selection signal, and wherein the output control circuit comprises: a first switch configured to output either one of the data voltage and second voltage in response to the selection signal; a second-first switch configured to output the data voltage or the second voltage outputted from the first switch to either one of the first and the second line in response to the selection signal; and a second-second switch configured to output the first voltage to the remaining one of the first and the second line.
