| description | An organic light-emitting diode (OLED) driving characteristic detection circuit is provided. The OLED driving characteristic detection circuit comprising a first current integrator receiving a first current via a first sensing channel and outputting a first sampling voltage based on the first current, a second current integrator receiving a second current via a second sensing channel and outputting a second sampling voltage based on the second current, and a sampling circuit receiving the first and second sampling voltages, followed by storing and holding the first and second sampling voltages, and removing common noise components included in the first and second sampling voltages, a third sampling capacitor and a fourth sampling capacitor which are connected to an output terminal of the second current integrator and store and hold the second sampling voltage, and a plurality of switches which connect first ends of the first sampling capacitor to the fourth sampling capacitor. |
