Patent ID: 7408533

Claim:
A light emitting display comprising: a plurality of scan lines for transmitting a select signal; a plurality of data lines for transmitting a data signal; a plurality of pixel circuits, each coupled to at least one of the plurality of scan lines and at least one of the plurality of data lines, at least one of the pixel circuits comprising: a transistor; a first capacitor having a first end coupled to a gate electrode of the transistor; a second capacitor coupled at one end to a first power line and connected at the other end to a second end of the first capacitor; a first switch coupled between the gate electrode and a first main electrode of the transistor, wherein the first switch is turned on in response to a first level of a first control signal, thereby diode-coupling the transistor; a light emitting element for emitting light corresponding to a current flowing out of the first main electrode of the transistor; and a second switch for being turned on in response to a second level of a second control signal for transmitting the current flowing out of the first main electrode of the transistor; and a control signal driver configured to provide the first control sianal to the first switch and the second control signal to the second switch, to have the second switch ON during a first period while the first switch is ON, to turn off the second switch after the first period while the first switch remains ON, and to turn on the second switch after the first switch is turned off.
