Claim 0:
1. A circuit for sensing characteristics of a pixel disposed on a display panel, comprising:
an integrator for integrating a current of the pixel and configured to receive a first operation signal in a sensing section of the display panel and a second operation signal in a display section of the display panel,
a sample and hold circuit configured to hold an output signal of the integrator, and
an analog-to-digital converting (ADC) circuit configured to convert an output signal of the sample and hold circuit into digital data,
wherein, when the integrator receives the first operation signal in the sensing section of the display panel, the integrator integrates a current of the pixel in an operation section set by the first operation signal, and
wherein, when the integrator receives the second operation signal in the display section of the display panel before receiving the first operation signal, the integrator starts operating in a preliminary operation section set by the second operation signal.
