Abstract

A redundant display uses row and column drivers to control an active matrix of transistors arranged in a pixel array. Row drivers arranged on respective sides of the pixel array control the voltage across entire rows of the pixel array in tandem. One or more sets of column drivers control the voltage across columns of the pixel array. One or more columns of switching elements are disposed between left and right portions of the pixel array. During normal operation, the column of switching elements connects left row portions with right row portions, such that an image is displayed across the entire pixel array. Responsive to a malfunction of row drivers on one side of the pixel array, the column of switching elements isolates the left row portions from the right row portions, such that the image may be displayed only on the other side of the pixel array.
