Abstract: A display device includes a defect inspection circuit, and a display panel having a display area and a peripheral area positioned outside the display area. The display panel includes a sensing wire positioned in the peripheral area and connected to the defect inspection circuit. The defect inspection circuit includes a resistance detection circuit that detects a resistance of the sensing wire based on an output signal corresponding to the sensing wire, a memory that stores first resistance information related to the resistance of the sensing wire detected in a first inspection operation, and a comparator circuit including a first comparator that compares the first resistance information with second resistance information. The second resistance information is related to the resistance of the sensing wire detected in a second inspection operation that is performed at a different time than the first inspection operation.

Abstract: A display device includes a display panel having a display area and a peripheral area. The display device includes a circuit having a comparator, and first and second sense wires disposed in the peripheral area and connected to the circuit. The comparator compares a first output signal output from the first sense wire and a second output signal output from the second sense wire to generate a comparison result. The circuit determines whether a defect is present in the display device based on the comparison result.

Abstract: An organic light-emitting diode display is disclosed. The display includes a scan line formed over a substrate and configured to carry a scan signal. First and second data lines are adjacent to each other and crossing the scan line. The first and second data lines are configured carry a data voltage. A driving voltage line crossing the scan line is configured to carry a driving voltage, and a switching transistor is electrically connected to the scan line and the data line and includes a switching drain electrode configured to output the data voltage. A driving transistor includes a driving gate electrode and a driving source electrode electrically connected to the switching drain electrode. An OLED is electrically connected to the driving drain electrode of the driving transistor, and a connector is connected to the driving gate electrode of the driving transistor and interposed between the first and second data lines.
