  • Publication number: 20160365022
    Abstract: This application is directed to driving methods for electrophoretic displays. The driving methods and waveforms have the advantage that they provide a clean and smooth transition from one image to another image, without flashing or other undesired visual interruptions. The methods also provide faster image transitions. In an embodiment, a method drives a display device from a first image to a second image wherein images of a first color are displayed with a background of a second color, which method comprises driving pixels of the first color directly to the second color before driving pixels of the second color directly to the first color.

  • Patent number: 9251736
    Abstract: This application is directed to driving methods for electrophoretic displays. The driving methods comprise applying different voltages selected from multiple voltage levels, to pixel electrodes and optionally also to the common electrodes. In one embodiment, the different voltages are selected from a group consisting of 0V, at least two levels of positive voltage and at least two levels of negative voltage. The driving method is also suitable for a color display device.

  • Patent number: 9019318
    Abstract: This application is directed to driving methods for electrophoretic displays. The driving methods comprise grey level waveforms which greatly enhance the pictorial quality of images displayed. The driving method comprises: (a) applying waveform to drive each pixel to the full first color then to a color state of a desired level; or (b) applying waveform to drive each pixel to the full second color then to a color state of a desired level.

  • Publication number: 20100194789
    Abstract: The present invention is directed to methods for partial image updates. Such methods provide the display controller the ability to update selected areas of an image that require updating and leave other areas unchanged. The methods also allow for multiple waveforms to be used for specific regions, giving the display the capability of updating each region with its own waveform.
