MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202617096437 A) filed by E Ink Corporation on August 10, 2026, for Improved Wave Switching For Electro-Optic Displays.
Inventor includes Harris, George G..
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: Methods for driving "spaced contact" electro-optic displays and "isolated electrode" electro-optic displays, such as electrophoretic displays including charged pigment particles disposed in a solvent that move in response to applied electric fields. The improved methods provide "wave switching" waveforms that have less visual "dead time" than prior art wave switching methods. The improved methods provide DC balanced waveforms that allow for a banner-type display to wave switch from a first color to a second color in a first direction and then return to the first color from the second color in an opposite direction. Such switching was not viable in prior art devices for fear of runaway remnant voltage build up that can destroy the display.
