Patent ID: 7978187

Claim:
A pixel circuit for use in a display, the display comprising a plurality of pixels with each pixel having a select line, a signal line, a feedback line, each of the pixels comprising: a light emitting element; a drive part for providing a drive current to the light emitting element, the drive part having a storage capacitor, a switch use transistor having a gate terminal connected to the select line, and a first terminal connected to the signal line, and a second terminal connected to the storage capacitor, a drive use transistor having a gate terminal connected to the second terminal of the switch use transistor, a first terminal connected to the light emitting element, and a second terminal, and a feedback switch having a first terminal connected to the drive use transistor, and a second terminal connected to the feedback line; and an on-pixel feedback conductive path between the second terminal of the drive use transistor and a reference potential for generating a feedback voltage representing a drive current provided to the light emitting element, the feedback voltage being provided to the feedback line via the feedback switch.
