Abstract:
A driving circuit for real-time external compensation and an electroluminescent display including the same are disclosed. The driving circuit includes a timing controller generating a gate shift clock group, a gate start pulse, and first and second selection signals and a gate driver generating a gate signal based on the control of the timing controller and supplying the gate signal to a display panel. The gate driver includes a plurality of stages which shifts the gate start pulse in accordance with the gate shift clock group to generate an output signal and supplies the output signal to a first output node, a first output control switch connected between a second output node connected to a gate line of the display panel and the first output node, and a second output control switch connected between the second output node and an input terminal of a gate low voltage.
