  • 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.

  • Patent number: 8446396
    Abstract: A bi-stable display, frame updating method and timing sequence controlling method thereof are disclosed. The frame updating method of the bi-stable display includes the steps of comparing a difference of source driver output voltages of adjacent frames of image updating period with a preset threshold, and determining parameter value of each transitional state of the adjacent frames when the difference equal or greater than the preset threshold for controlling level of source driver output voltage. Accordingly, the effects such as signal interference, reduction of image quality resulted from switching between high voltage levels directly and rapidly and excessive power consumption may be eliminated.
