Abstract: A gate driver and a display device comprising the same are discussed. The gate driver can comprise a plurality of stages for individually driving a plurality of gate lines by a combination of a plurality of group signals, a plurality of block signals, and a plurality of clock signals. Each of the plurality of stages driven independently can include an output buffer including a pull-up transistor configured to generate and output a gate-on level of a scan signal under the control of a first node, and a pull-down transistor configured to generate and output a gate-off level of the scan signal under the control of a second node. Each stage can further include a first controller configured to control the first node, and a second controller configured to control the second node to be opposite to the operation of the first node.

Abstract: An organic light emitting display device is disclosed, which may increase sensing accuracy by solving a problem that a difference between sensing data output from sensing units is generated due to a difference in sensing capability between the sensing units. The organic light emitting display device includes a display panel including data lines, scan lines, sensing lines, and pixels connected to the data lines, the scan lines and the sensing lines; a sensing data output unit outputting first sensing data by sensing currents flowing to the sensing lines; a scan driver supplying scan signals to the scan lines; and a source drive integrated circuit (IC) including a data voltage supply unit supplying data voltages to the data lines and a switching unit connecting the sensing lines to the sensing data output unit in a predetermined order.
