Classification: CPC H  G | IPC G  H

Claim 11:
12. A driving method of a display device including a plurality of data signal lines, a plurality of scanning signal lines, and pixel circuits of m rows×n columns (m and n are integers of 2 or more) provided corresponding to intersections of the plurality of data signal lines and the plurality of scanning signal lines, the display device having a function of detecting a characteristic of a circuit element included in each pixel circuit, the driving method comprising steps of:
applying an initialization potential configured to initialize a state of the pixel circuit to each of the plurality of data signal lines
applying a characteristic detection potential as a data signal configured to detect the characteristic of the circuit element to each of the plurality of data signal lines,
applying a current measurement potential as a data signal configured to measure a current representative of a characteristic of the circuit element to each of the plurality of data signal lines,
performing current measurement charging based on a current flowing through each of the plurality of data signal lines, and
performing A/D conversion based on a charging voltage obtained in the performing current measurement charging,
wherein at least two of the applying an initialization potential, the applying a characteristic detection potential, the applying a current measurement potential, the performing current measurement charging, and the performing A/D conversion are started at a same timing.
