Method for saving power in an organic electroluminescent display using white light emitting elements
First Claim
1. A method of saving power in a color organic electroluminescent display of the type having color emitting elements with different light emitting efficiencies, comprising the steps of:
- a) providing an organic electroluminescent color display having colored light emitting elements and white light emitting elements;
b) converting at least a portion of a color digital image to be displayed on the display to a monochrome image; and
c) displaying the monochrome image portion using only the white light emitting elements.
