摘要： 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.

摘要： An organic light-emitting diode (OLED) display is disclosed. In one aspect, the display includes a plurality of pixels and a data line formed adjacent to the pixels and configured to transfer a data voltage. The display also includes a driving voltage line formed substantially parallel to the data line and configured to transfer a driving voltage, and an initialization voltage line formed substantially parallel to the data line and configured transfer an initialization voltage. At least one of the pixels includes a driving transistor including a driving gate electrode and configured to receive the initialization voltage from the initialization voltage line. A driving connector is spaced apart from the data line and electrically connected to the driving gate electrode. An OLED is electrically connected to the driving transistor, at least one of the initialization voltage line and the driving voltage line interposed between the driving connector and the data line.
