06229506 is referenced by 665 patents and cites 28 patents.

A LED pixel structure that reduces current nonuniformities and threshold voltage variations in a “drive transistor”of the pixel structure is disclosed. The LED pixel structure incorporates a current source for loading data into the pixel via a data line. Alternatively, an auto zero voltage is determined for the drive transistor prior to the loading of data.
