Patent number: 9886886Abstract: An electro-optic display, having at least one pixel capable of achieving any one of at least four different gray levels including two extreme optical states, is driven by displaying a first image on the display, and rewriting the display to display a second image thereon, wherein, during the rewriting of the display, any pixel which has undergone a number of transitions exceeding a predetermined value without touching an extreme optical state, is driven to at least one extreme optical state before driving that pixel to its final optical state in the second image.Type: GrantFiled: July 5, 2016Date of Patent: February 6, 2018Assignee: E Ink CorporationInventors: Karl R. Amundson, Robert W. Zehner, Ara N. Knaian, Benjamin Zion

Patent number: 8174490Abstract: A pixel of an electrophoretic display is driven from one extreme optical state to a second optical state different from the one extreme optical state by applying to the pixel a first drive pulse of one polarity; and thereafter applying to the pixel a second drive pulse of the opposite polarity, the second drive pulse being effective to drive the pixel to the second optical state.Type: GrantFiled: August 28, 2007Date of Patent: May 8, 2012Assignee: E Ink CorporationInventors: Thomas H. Whitesides, Joanna F. Au, Karl R. Amundson, Robert W. Zehner, Ara N. Knaian, Benjamin Zion

Patent number: 7733311Abstract: A gray scale bistable electro-optic display is driven by storing a look-up table containing data representing the impulses necessary for transitions, storing data representing at least an initial state of each pixel of the display, storing data representing temporal and gray level prior states of each pixel, receiving an input signal representing a desired final state of at least one pixel of the display; and generating an output signal representing the impulse necessary for a transition, as determined from the look-up table, dependent upon the temporal and gray level prior states. Other similar methods for driving such displays are also disclosed.Type: GrantFiled: June 21, 2006Date of Patent: June 8, 2010Assignee: E Ink CorporationInventors: Karl R. Amundson, Robert W.

Publication number: 20070103427Abstract: A cyclic rail-stabilized method of driving an electrophoretic display device (1), wherein a substantially dc-balanced driving waveform is used to effect the various required optical transitions. The driving waveform consists of a plurality of picture potential differences (20), which cause the charged particles (6) of the electrophoretic device (1) to cyclically between extreme optical positions in a single optical path, irrespective of the image sequence required to be displayed, i.e. in order to display each grey scale, it is necessary for the particles (6) to first pass through one of the extreme optical states. In order to minimise the effects of dwell time on the image quality and minimise, or even eliminate, the need to consider image history, shaking pulses (10) are generated immediately prior to each picture potential difference (20).Type: ApplicationFiled: November 23, 2004Publication date: May 10, 2007Inventors: Guofu Zhou, Ara Knaian, Karl Amundson, Alexander Henzen, Johannes Van De Kamer, Robert Zehner, Benjamin Zion, Neculai Ailenei
