Patent number: 10535312Abstract: A method for driving a display having a plurality of pixels, where each pixel is capable of displaying a first color or a second color and is sandwiched between a first electrode and a pixel electrode, the method including applying a driving sequence which includes: (a) for a first time period, applying a first voltage potential between the first electrode and each of the pixel electrodes of a first group of pixels, and applying no voltage potential between the first electrode and each of the pixel electrodes of a second group of pixels of the second color, thereby causing the display device to display an image of the first color with a background of the second color; and (b) for a second time period, applying no voltage potential between the first electrode and each of the pixel electrodes of the first group of pixels, and applying a second voltage potential to each of the pixel electrodes corresponding to the second group of pixels, to clear the onetime image created in step (a).Type: GrantFiled: May 22, 2018Date of Patent: January 14, 2020Assignee: E INK CALIFORNIA, LLCInventors: Robert A. Sprague, Andrew Ho, Yajuan Chen, HongMei Zang, Jialock Wong, Chein Wang

Patent number: 9171508Abstract: The invention relates to waveforms, circuits and methods for driving bistable displays. The invention is directed to a method, comprising in combination: applying, across a bistable display device, a shaking signal comprising a plurality of positive and negative pulses each driven for a first time to disperse partially packed particles; applying, across the device, one or more first driving signals to first pixels of the device for second times that are sufficient to drive the first pixels to one or more reference states; and concurrently with the first driving signals, applying, across the device, one or more second driving signals to second pixels of the device for third times that are shorter than necessary to drive the second pixels to any of the one or more reference states.Type: GrantFiled: April 11, 2014Date of Patent: October 27, 2015Assignee: E Ink California, LLCInventors: Robert A. Sprague, Wanheng Wang, Yajuan Chen, Andrew Ho, Bryan Hans Chan, Jialock Wong, HongMei Zang
