Abstract
A technique for driving a column of pixels that include light emitting elements. The technique incorporates feedback data provided from feedback data sources connected to the data line and to feedback line of the array, pixel driving circuit with feedback path. The technique can also include block of the reference elements for input signal corrections.
Claims13
A pixel circuit for use in a display, the display comprising a plurality of pixels, each of the pixels comprising:
- a light emitting element;
- a drive use transistor for providing a drive current to the light emitting element;
- and
- an on-pixel feedback circuit for generating a feedback voltage from a node through which a current proportional to the drive current passes, the feedback voltage representing the drive current and provided to a feedback line of the display.
