Abstract:
An electroluminescence display apparatus includes a display panel including a first pixel and a second pixel, a first current integrator connected to the first pixel through a first sensing channel to sense a first current from the first pixel to generate a first output voltage, a second current integrator connected to the second pixel through a second sensing channel to sense a second current from the second pixel to generate a second output voltage, and a sampling capacitor connected to an output terminal of the first current integrator at one electrode thereof and connected to an output terminal of the second current integrator at the other electrode thereof, thereby sampling the first output voltage and the second output voltage.
