ABSTRACT:
A display system has signal lines and scanning lines arranged in a matrix with the signal lines extending generally perpendicular to the scanning lines. At each intersection of the signal and scanning lines is a display unit, each such unit having a display element such as a liquid crystal display element, a switching means between the display element and the signal line, and a current limiting means between the switching element and the scanning line. By applying suitable signals to the signal and scanning lines, from suitable signal and scanning controllers, each display unit may be addressed. In order to prevent defects due to a short circuit across the switching element between the current limiting means and the signal line, signals are applied to the signal lines at times other than when signals are applied to the scanning lines. Therefore, a suitable voltage can be applied to any defective display unit so as to cause the display element to be controlled so that it is in the desired state. Thus, if the display elements are liquid crystals, they may be controlled so as to be dark if they are faulty.
