Patent number: 9726880Abstract: In a system having a matrix of electrowetting display elements, a column driving system transmits a column voltage signal to an electrode of each electrowetting display element of at least one selected row of n rows of electrowetting display elements. A first row driving system transmits a first row voltage signal to a switchable element associated with each respective electrowetting display element of the selected row. A second row driving system transmits a second row voltage signal to the switchable element associated with each respective electrowetting display element of rows of the n rows of electrowetting display elements. A configuration of respective first and second fluids of the electrowetting display elements of at least one row of the n rows is controlled by selectively transmitting: the first row voltage signal using the first row driving system, and the second row voltage signal, using the second row driving system.Type: GrantFiled: December 24, 2014Date of Patent: August 8, 2017Assignee: Amazon Technologies, Inc.Inventors: Pavel Novoselov, Anthony John Slack, Henricus Petronella Maria Derckx, Jozef Elisabeth Aubert
