Patent ID: 7804483

Claim:
An improved addressing method for updating electrophoretic displays with lower latency for use with interactive applications, the method comprising: a) receiving drawing information for at least one electrophoretic pixel in the electrophoretic display; b) determining at least one drawing-mode waveform of the at least one electrophoretic pixel in the electrophoretic display based on the received drawing information for the at least one electrophoretic pixel; c) applying the at least one drawing-mode waveform a predetermined number of times to complete an image update onto the at least one electrophoretic pixel in the electrophoretic display, wherein the predetermined application of the at least one drawing mode waveform includes transitioning the at least one electrophoretic pixel from a current optical state and proceeding through at least one grey scale transition before arriving to a final optical state; and prior to the completion of the image update for the at least one electrophoretic pixel at said step (c) and subsequent to the start of the image update for the at least one electrophoretic pixel at said step (c): d) receiving drawing information for at least one additional electrophoretic pixel in the electrophoretic display, e) determining at least one drawing-mode waveform for the at least one additional electrophoretic pixel in the electrophoretic display based on the received drawing information for the at least one additional electrophoretic pixel in the electrophoretic display; f) applying the at least one drawing-mode waveform a predetermined number of times to complete an image update onto the at least one additional electrophoretic pixel in the electrophoretic display, wherein the predetermined application of the at least one drawing mode waveform includes transitioning the at least one additional electrophoretic pixel from a current optical state and proceeding through at least one grey scale transition before arriving to a final optical state.
