ABSTRACT:
The present invention replaces the conventional cold cathode fluorescent tubes used in backlighting units of liquid crystal displays with an integrated electro-luminescent film structure, subdivided into electrically isolated micro-panels. Ideally, the electro-luminescent structure comprises separate red, green and blue micro-panels providing full color capabilities. Alternatively, the electro-luminescent film structure includes stacked groups of layers, in which each group emits a different color and is independently controllable.
