Abstract: An organic light-emitting display device includes a display panel, a source driver, a scan driver, and a timing controller. A gate node of a second transistor of an (N−1)-th sub pixel and a gate node of a first transistor of an N-th sub pixel are connected in common such that the second transistor of the (N−1)-th sub pixel and the first transistor of the N-th sub pixel are simultaneously turned on by a scan signal supplied to the second transistor of the (N−1)-th sub pixel. Accordingly, it is possible to decrease a size of the scan driver and a bezel area.

Abstract: An organic light emitting display device having a data line that is used for sending data voltage signals to pixels from a data driver as well as send sensor signals for detecting threshold voltage levels of driving transistors in the pixels at different times. By using the same data line to transmit the data voltage signals and the sensor signals, the number of signal lines in the organic light emitting display can be reduced. The data driver also includes switches for selectively coupling the data line to a driver unit or an analog to digital converter (ADC) unit.

Abstract: Disclosed is an organic light-emitting display device defined into a non-display area and a display area which is provided with pixels. Each of the pixels includes: first through fourth nodes; an organic light emission element connected to the fourth node; a drive transistor disposed between the second, third, and fourth nodes and configured to generate a drive current which drives the organic light emission element to emit light; a storage capacitor disposed between the first and third nodes; first through fifth transistors; wherein the fifth transistor is disposed between the second node with the non-display area and a reference voltage line and configured to control an initialization of the second node.
