Electrophoretic displays using nanoparticles
Joseph M. Jacobson,Paul Drzaic,Ian Morrison,Anthony Edward Pullen,Jianna Wang,Robert W. Zehner,Caprice L Gray,Gregg M. Duthaler,Michael M Mccreary,Emily J Pratt +9 more
TL;DR: An electrophoretic display comprises a fluid and a plurality of nanoparticles having diameters substantially less the wavelengths of visible light such that, when the nanoparticles are in a dispersed state and uniformly dispersed throughout the fluid, the fluid presents a first optical characteristic, but when the aggregated particles are in an aggregated state in which they are gathered into aggregates substantially larger than the individual nanoparticles.

Methods for driving bistable electro-optic displays, and apparatus for use therein
Robert W. Zehner,Holly G. Gates,Karl R. Amundson,Joanna F. Au,Ara N. Knaian,Jonathan L. Zalesky,Alexi C. Arango +6 more
TL;DR: In this paper, a bistable electro-optic display has a plurality of pixels, each of which is capable of displaying at least three gray levels, and the display is driven by storing a look-up table containing data representing the impulses necessary to convert an initial gray level to a final gray level.
Patent
Methods for driving electro-optic displays
TL;DR: In this paper, 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.

Electro-optic displays, and methods for driving same
Justin Abramson,Karl R. Amundson,Guy M. Danner,Gregg M. Duthaler,Holly G. Gates,Charles Howie Honeyman,Ara N. Knaian,Ian Morrison,Steven J. O'neil,Richard J. Paolini,Anthony Edward Pullen,Jianna Wang,Jonathan L. Zalesky,Robert W. Zehner,John Edward Cronin +14 more
TL;DR: In this paper, the authors proposed a method for sealing electrochromic displays from the outside environment and preventing ingress of contaminants into such a display, as well as adjusting the driving of electro-optic displays to allow for environmental and operating parameters.

TL;DR: In this article, the front plane laminate of an electro-optic display is described as a continuous web, cut to size, the release sheet removed and the laminate laminated to a backplane to form a display.
