Driving circuit for real-time external compensation and electroluminescent display including the same

An electroluminescent display comprising:

• a display panel including a first display line for a display drive operation and a second display line for a sensing drive operation, a plurality of pixels displaying an input image being disposed on the first display line, a plurality of pixels, of which electrical characteristics are sensed, being disposed on the second display line;
• a timing controller configured to generate a gate shift clock group, a gate start pulse, and first and second selection signals including a period in which phases of the first and second selection signals are opposite to each other;
• and
• a gate driver configured to generate a gate signal based on at least one of the gate shift clock group, the gate start pulse, the first selection signal and the second selection signal generated by the timing controller, and to supply the gate signal to the display panel, the gate driver including:
• a plurality of stages configured to shift the gate start pulse in accordance with clock signals of the gate shift clock group to generate an output signal and supply the output signal to a first output node,
• a first output control switch connected between a second output node and the first output node, the first output control switch being turned on in response to the first selection signal to connect the first output node to the second output node, the second output node being connected to one of the first display line or the second display line, and
• a second output control switch connected between the second output node and an input terminal of a low potential voltage, the second output control switch being turned on in response to the second selection signal to connect the input terminal of the low potential voltage to the second output node,
• wherein the gate signal includes a sensing gate signal to be applied to the second display line and a pause-drive display gate signal for a first display line adjacent to the second display line, and
• wherein the first output control switch is turned off in response to the first selection signal and the second output control switch is turned on in response to the second selection signal, and the gate driver outputs the pause-drive display gate signal.
