Abstract
An organic light emitting diode display including a short detecting circuit and a method of driving the same are disclosed. The organic light emitting diode display includes a pixel unit including pixels coupled to scan lines and data lines, a DC-DC converter for outputting a first power source and a second power source when a start signal is supplied, a first power source line and a second power source line for supplying the first power source and the second power source output from the DC-DC converter to the pixel unit, and a short detecting circuit for determining whether the first power source line and the second power source line are shorted before the DC-DC converter is driven and for supplying the start signal to the DC-DC converter when the first power source line and the second power source line are not shorted.
