Abstract:
1. An organic light emitting diode (OLED) display comprising: a display panel including pixels formed at each of crossings of a plurality of gate lines and a plurality of data lines; a monitoring signal line formed along an outer area of the display panel on which an image is not displayed; a first signal supply unit that supplies a monitoring signal to the monitoring signal line and generates a first power control signal; a power supply unit that supplies a high potential driving voltage and a low potential driving voltage to the pixels in response to the first power control signal; and a second signal supply unit that monitors the monitoring signal and generates a second power control signal based on a monitoring result of the second signal supply unit that monitors, wherein if the monitoring signal is not monitored in a state where the high and low potential driving voltages are supplied to the pixels, the second signal supply unit controls the power supply unit using the second power control signal and allows the power supply unit to stop supplying one of the high and low potential driving voltages to the pixels, and wherein the first signal supply unit supplies the monitoring signal to the second signal supply unit through the monitoring signal line.
