Abstract
Official abstract text for this publication.
The present invention is directed to methods for adjusting or selecting driving waveforms in order to achieve a consistent optical performance of a display device. When a method of the present invention is applied, even if there are changes in the display medium due to temperature variation, photo-exposure or aging, the optical performance can be maintained at a desired level.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for adjusting the performance of an electrophoretic display device comprising a display medium, the method comprises the steps in the order of: (a) providing a first set of driving waveforms and a sequence of blocks; (b) driving the blocks from a first color state to increasing levels of a second color state with the first set of driving waveforms and identifying the location of a first block which is at the full second color state, which is indi…
