Abstract
An enhanced manufacturing yield of a high resolution, high accuracy information conversion device, such as a liquid crystal display, is attained through incorporation into the device of auxiliary address lines. Such auxiliary address lines are used to provide electrical communication with portions of main address lines that, due to the presence of electrical open circuits, would otherwise be electrically isolated. Each auxiliary address line crosses over multiple main address lines and can be electrically shorted to any such main address line to provide electrical communication therewith. The ratio of auxiliary address lines to main address lines is accordingly low, such as 1:10 or less, for example.
