摘要: A system and method are disclosed for reducing reverse bias in an electrophoretic display. The system and method include the application of varying levels of voltages across an array of electrophoretic display cells of the electrophoretic display to move the cells towards a stable state in a driving cycle. In addition, the system and method disconnect the voltages from the electrophoretic display cells at a time duration prior to reaching step transitions of the voltages during the driving cycle. Pre-driving approaches apply a first pre-driving voltage at a first polarity to the display cells before driving the display cells with a second driving voltage at a second, opposite polarity. Varying the time duration and amplitude of the pre-driving signals produces further beneficial reduction in reverse bias.

摘要: 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.
