Problems solved by technology

As the resolution of organic light-emitting display devices increases, the number of required data driver ICs may also increase, and as a result, it may become more difficult to arrange in a limited space the size-increased ICs due to the incorporation of readout circuit units. Each data driver IC
In addition, since the driving information can be read out via the data line, the capacitance of the data line may increase, and as a result, the heat generated by the data driving IC may also increase
In addition, it may be difficult to perform accurate detection since a leakage path may be formed from the source electrode to the drain electrode

Abstract

Provided is an organic light emitting display device, which can more accurately measure driving information of each pixel on a different path other than a data line. The organic light emitting display device includes: a first transistor including a gate electrode connected to a scan line, a first electrode connected to a data line, and a second electrode connected to a first node; a second transistor including a gate electrode connected to a first node, the first electrode connected to a first power voltage, and the second electrode connected to a second node; a third transistor including a gate electrode connected to a sensing control line, the first electrode connected to the scan line, and the second electrode connected to the second node; and an organic light emitting element including an anode electrode connected to the second node and a cathode electrode connected to a second power voltage.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2014-0137770 filed with the Korean Intellectual Property Office on Oct. 13, 2014, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The invention relates to an organic light emitting display device and a driving method thereof. Background technique [0004] Organic light-emitting display devices, which are gaining prominence as next-generation display devices, are equipped with self-luminous elements and thus can provide various benefits such as fast response speed, high luminous efficiency, high luminance, and wide viewing angle. An organic light emitting display device includes an organic light emitting diode (OLED) as a self-emitting element. An OLED includes an anode, a cathode, and an organic compound layer formed between the anode and the cathode. The organic compound layer incl...
