Patent ID: 8149189

Claim:
An organic light emitting diode display comprising: a first scan switching element controlled in response to a first scan signal from a first scan line, the first scan switching element being connected between a first data line and a first node; a first storage capacitor connected between the first node and an alternating current (AC) voltage supply line; a first driving switching element controlled in response to a signal applied to the first node, the first driving switching element being connected between a second node and the AC voltage supply line; a light emitting element connected between a high-level voltage supply line and the second node; a first sensing switching element controlled in response to a first gate signal from a first gate line, the first sensing switching element being connected between the first data line and the second node; a second scan switching element controlled in response to a second scan signal from a second scan line, the second scan switching element being connected between a second data line and a third node; a second storage capacitor connected between the third node and the AC voltage supply line; and a second driving switching element controlled in response to a signal applied to the third node, the second driving switching element being connected between the second node and the AC voltage supply line.
