Abstract
An organic light-emitting display includes: a display panel including first and second pixels, each having an organic light-emitting diode; and a data driver including a first operational amplifier having a non-inverting terminal coupled to a reference voltage terminal and an inverting terminal coupled to the first pixel, and a second operational amplifier having a non-inverting terminal coupled to the reference voltage terminal and an inverting terminal coupled to the second pixel. The first pixel includes a sensing transistor, a first driving transistor, and a first switch transistor. The second pixel includes a second driving transistor and a second switch transistor.

A light-emitting display comprising:
- a display panel comprising a first pixel;
- a first data line electrically connected to the first pixel;
- a data driver electrically connected to the first data line;
- wherein the first pixel comprises:
- a first light-emitting diode;
- a sensing transistor comprising a first electrode electrically connected to the first data line and a second electrode electrically connected to the first light-emitting diode of the first pixel,
- a first driving transistor comprising a first electrode electrically connected to a first power supply terminal and a second electrode electrically connected to the first light-emitting diode;
- and
- a first switch transistor comprising a first electrode electrically connected to the first data line and a second electrode electrically connected to a gate electrode of the first driving transistor,
- wherein the data driver is configured to apply a data signal to the gate electrode of the first driving transistor through the first data line during a display period, and
- wherein the data driver is configured to apply a reference voltage to the first light-emitting diode through the sensing transistor during a sensing period.
