Abstract: A pixel includes a pixel circuit and an organic light emitting diode. The pixel circuit has first, second, third, and fourth transistors. The first transistor controls an amount of current flowing from a first driving power supply coupled to a first node to a second driving power supply through the organic light emitting diode. The turns on when a scan signal is supplied to a first scan line. The third transistor turns on when a scan signal is supplied to a second scan line. The fourth transistor turns on when a scan signal is supplied to a third scan line. The first transistor is a p-type Low Temperature Poly-Silicon thin film transistor and the third transistor and the fourth transistor are n-type oxide semiconductor thin film transistors.

Abstract: An organic light emitting display device includes a pixel, a data line, a first scan line, a second scan line, and a scan driver. The pixel includes a first transistor, a second transistor, and a third transistor. A source of the first transistor is electrically connected to a drain of the third transistor. A source of the second transistor is configured to receive an initialization voltage. The data line is electrically connected to a source of the third transistor and may transmit a data voltage higher than the initialization voltage. The first scan line is electrically connected to a gate of the third transistor. The second scan line is electrically connected to a gate of the second transistor. The scan driver may provide an initializing scan signal to the second scan line at least two horizontal periods before providing an initial scan signal to the first scan line.

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.
