Abstract

Official abstract text for this publication.

Methods and devices for reducing the voltage required to update an array of display elements having variable capacitance are described herein. In one implementation, the method includes driving a display element to a first state using a reset drive line. The method further includes driving the display element to a second state using a column drive line. The capacitance of the display element is higher in the first state than in the second state.

First claim

Opening claim text (preview).

What is claimed is: 1. An apparatus comprising: at least one display element having a plurality of display states, each of the display states corresponding to one of a plurality of charge levels applied to the at least one display element, the plurality of display states including a least a first higher capacitance display state and a second display state, wherein the capacitance of the display element is higher in the first higher capacitance display state than in the second disp…
