Claim 9:
10. A display driving integrated circuit comprising:
a data driving circuit which supplies a data voltage to a data line connected to a pixel in a display section, a frame divided into the display section and a sensing section; and
a pixel sensing circuit which senses characteristics of the pixel in the sensing section,
wherein the pixel sensing circuit comprises an integrator for integrating a current of the pixel and configured to receive a first operation signal in the sensing section and a second operation signal in the display section, 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, and
wherein the pixel sensing circuit starts operating for a sensing by receiving the second operation signal in the display section at a time point earlier than a start time point of the sensing section set by the first operation signal in the sensing section.
