<p>A LED pixel structure (200, 300, 400, 600, 700) that reduces current nonuformities 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.</p> |
