DRIVING METHOD AND SYSTEM FOR ELECTROFLUIDIC CHROMATOPHORE PIXEL DISPLAY

摘要

The invention concerns a display comprising a plurality of electrofluidic chromatophore (EFC) pixel cells. The display comprises a controller executing the steps of storing the present cell display properties of the pixel cells displaying the present image content, comparing the present cell display properties with next cell display properties of the pixel cells, determining still-image pixels displaying still- image content wherein the present cell display properties of the pixels are substantially identical to the next cell display properties of the pixels, and providing a still-image drive scheme. The still-image drive scheme involves addressing a voltage to the another one pixel cell terminal of the still-image pixels, the still image voltage being derived from the stable supply voltage that stabilizes the cell display properties of the still-image pixels, so as to display still-image content in an energy efficient manner.
