Abstract
A passive dot matrix liquid crystal display having improved visibility comprises plural column electrodes on a first plate interconnected by a plurality of electrode bridges to form groups of interconnected column electrodes, wherein the number of electrodes in each electrode group is equal to or less than the inverse of the multiplex ratio of the display. The display also comprises plural row electrodes interconnected by a plurality of electrode bridges to form groups of interconnected row electrodes, wherein the number of groups of interconnected row electrodes is equal to the multiplex ratio of the display. By grouping the row and column electrodes into such groups, the multiplex ratio of the display can be reduced to levels substantially below the multiplex ratios of conventional passive dot matrix Liquid Crystal Displays, thereby significantly enhancing visibility of the display.
