Abstract:
The present invention is directed to a driving method for compensating the response speed change of an electrophoretic display due to temperature variation, photo-degradation or aging of the display device, without a complex structure (e.g., use of sensors). This is accomplished by combining two waveforms, one of which causes the grey level to become dimmer and the other waveform causes the grey level to become brighter, as the response speed degrades.
