Abstract
An electroluminescence display apparatus includes a pixel and a sensing circuit supplying a pixel reference voltage to the pixel through a reference voltage line during display driving and sensing a pixel current, flowing in the pixel, through the reference voltage line during sensing driving succeeding the display driving operation. The sensing circuit includes a sensing channel terminal connected to the reference voltage line, a first switch between the sensing channel terminal and an input terminal for the pixel reference voltage, an integrator amplifier including a first input terminal, a second input terminal, and an output terminal, an input terminal for an integrator reference voltage connected to the second input terminal, a second switch between the first input terminal and the output terminal, a first capacitor between the sensing channel terminal and the first input terminal, and a second capacitor between the sensing channel terminal and the output terminal.
