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: A display panel includes a plurality of pixels, a gate driver, a clock pad, and a buffer circuit. The gate driver supplies gate signals to the plurality of pixels. The clock pad receives a clock signal. The buffer circuit is connected between the clock pad and the gate driver. The buffer circuit compensates for an RC delay of the clock signal received through the clock pad, and supplies the clock signal of which the RC delay is compensated to the gate driver.

Abstract: A display device includes a display area configured to include a plurality of pixels and a plurality of data lines connected to the pixels. A hole area is disposed within the display area. A hole crack detection line is disposed adjacent to the hole area and surrounds the hole area. The device includes first and second detection lines which include first and second detection transfer lines and first and second detection receiving lines, respectively. A test controller electrically connects the first detection receiving line to a first data line and the second detection receiving line to a second data line. Pixels connected to the first data line that is connected to a first bright-line transistor and pixels connected to the second data line that is connected to a second bright-line transistor are configured to emit light when a crack occurs in the hole crack detection line.
