Abstract: A gate driver according to an embodiment and a display device using the same are discussed. The gate driver can output a gate signal to a pixel circuit having a driving element connected between a first power line and a first node, a light-emitting element connected between the first node and a second power line, and a switching element connected between the first node and a third power line and driven by the gate signal. The gate driver includes a first circuit unit to receive a carry signal from a previous signal transmission unit to charge or discharge a first control node and a second control node, and a second circuit unit having a first buffer transistor and a second buffer transistor configured to output the gate signal based on a first clock signal and a first low potential voltage according to potentials of the first and second control nodes.

Abstract: The present disclosure is directed to a gate driver circuit configured to prevent a light-emitting element of a display device from emitting light in a sensing mode. The gate driver circuit allows a plurality of scan lines of the display device being concurrently sensed by pre-charging a node of the gate driver circuit prior starting a sensing mode. The present disclosure provides the benefit of sensing a greater number of pixels of a display in a shorter time while also ensuring that a sufficient charge is provided by the pre-charged node for a plurality of pixels of the plurality of scan lines to be sensed concurrently.
