Patent ID: 8289240

Claim:
A display comprising: a data line for transmitting a data current; a scan line for applying a select signal; a first 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 first 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; at least one second switch for electrically coupling the second electrode of the transistor to the control electrode of the transistor in the first period and a second period before the first period; a first capacitor coupled between the first electrode of the transistor and the control electrode of the transistor, and for storing a voltage corresponding to the data current flowing through the first 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, wherein the first capacitor is charged with the voltage corresponding to the data current flowing through the first switch only when the one end of the second capacitor is blocked from the first capacitor.
