Abstract
A pixel circuit for a display includes a pixel storage node for storing and presenting a pixel voltage to a pixel display element, a cell storage node for storing the data on the pixel storage node, and a first storage capacitor and a second storage capacitor each including a first electrode and a second electrode. The first electrode of the first storage capacitor is operatively coupled to the pixel storage node and the first electrode of the second storage capacitor operatively coupled to the cell storage node. The second electrode of the first and second storage capacitors is operatively coupled to a respective different one of first and second independent voltage signal lines. The pixel circuit further includes a pixel write circuit configured to write the pixel voltage to the pixel storage node during a data write cycle, and to provide respective voltage signals to the first and second independent voltage signal lines, each of the respective voltage signals being changed during the data write cycle in order to increase or reduce the pixel voltage.
