Abstract
The driving system and methods of the present invention enable interruption of updating images. The system and methods have the advantage that they not only can speed up the updating process when more than one command is received consecutively in a short period of time, but also can provide a more smooth transition visually during the updating process.

A driving method for continuously updating multiple images utilizing waveform phase A which drives pixels of a first color to a second color and waveform phase B which drives pixels of the second color to the first color, the method comprises the following steps:
- a) completing a phase A to update a current image to an intermediate state image, in response to an initial command to update the current image to a first next image;
- and
- b) completing a phase B to update the intermediate state image to a second next image, in response to a second command received in the phase A to update to the second next image.
A driving method for continuously updating multiple images utilizing waveform phase A which drives pixels of a first color to a second color and waveform phase B which drives pixels of the second color to the first color, the method comprises the following steps:
- a) completing a first phase A to update a current image to an intermediate state image, in response to an initial command to update the current image to a first next image;
- b) partially completing a first phase B to update to a transition image and terminating the first phase B, in response to a second command to update to a second next image which command is received in the first phase B;
- c) starting a second phase A at an appropriate frame and completing the second phase A to update to a second intermediate state image;
- and
- d) completing a second phase B to update to the second next image.
