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.

Redundant display systems and methods for use thereof in safety critical applications

A segmented redundant display cell driver interface system and method wherein each of the drivers are totally independent from each other. The system and method provide segmented redundant display cell drive interfaces that drive the display normally in a failure free mode, and that additionally can independently drive a portion of the display in the event of a failure in the drive electronics. With the segmented redundant display cell driver interface, the drive function can be segmented into N independent segments. With N segments, a failure on one of the driver interface boards would cause the loss of 1/Nth of the display, with the remaining display still operational. In the alternative, all the remaining displays could be repositioned by software so that no sub-display information is lost.
