Abstract
Official abstract text for this publication.
A system and method are disclosed for determining a pixel capacitance. The pixel capacitance is correlated to a pixel age to determine a current correction factor used for compensating the pixel drive current to account for luminance degradation of the pixel that results from the pixel aging.
First claim
Opening claim text (preview).
What is claimed is: 1. A display for driving an array of a plurality of pixel circuits with a current compensated for luminance degradation, each of said pixel circuits having an electroluminescent device, the display comprising: a display panel comprising the array of pixel circuits, the pixel circuits arranged in at least one row and a plurality of columns; a column driver for driving the electroluminescent devices in the pixel circuits with a driving current; a base pixel i…
