Patent ID: 7573441

Claim:
A display comprising: a data line for transmitting a data current; a scan line for applying a select signal; a switch coupled to the data line and turned on in response to the select signal from the scan line in a first period such that the data current flows through the switch; a transistor having a first electrode, a second electrode and a control electrode, and for providing a current corresponding to a voltage between the first electrode and the control electrode through the second electrode; a first capacitor coupled between the first electrode and the control electrode of the transistor, for storing a voltage corresponding to a threshold voltage of the transistor in a second period before the first period, and for storing a voltage corresponding to the data current flowing through the switch in the first period; a second capacitor electrically coupled to the first capacitor in parallel in the second period and a third period after the first period, and having one end electrically blocked from the first capacitor in the first period; and an emitting element for emitting light in response to the current provided through the second electrode of the transistor in the third period.
