Abstract
(EN)
A method for driving an electro-optic display, the display having at least one display pixel coupled to a storage capacitor, the method include applying a waveform sequence to the at least one display pixel and connecting the storage capacitor to a first bias voltage, and maintaining a last frame voltage level on the display pixel after the completion of the applied waveform.
