  • Patent number: 8711082
    Abstract: A method for driving a bistable display device is provided. The bistable display device has a matrix of pixels arranged in a plurality of rows and a plurality of columns, a timing controller and a source driver. The timing controller is configured to sequentially output control signals which correspond to a positive high voltage, a negative high voltage and a ground voltage respectively to the source driver. The source driver is configured to drive each pixel with the voltages corresponding to the control signals. The method comprises: providing only the positive high voltage or the ground voltage to one of two pixels in two adjacent rows of the same column if the source driver provides the positive high voltage to the other one when the source driver consecutively drives the two pixels.

  • Publication number: 20110141099
    Abstract: A driving method for pixels of bistable display is adapted into a bistable display having a plurality of pixels. The driving method comprises: increasing predetermined driving forces of the pixels to increased driving forces in a predetermined period; employing the increased driving forces to drive the pixels in the predetermined period respectively; and employing the predetermined driving forces configured for driving the pixels to drive the pixels out of the predetermined period respectively.
