ABSTRACT:
An LCD display having at least one redundant data driving circuit on a substrate that can be substituted for a defective data driving circuit on the substrate. These redundant subcircuits are exact copies of a column driving subcircuit except that some of the connecting points to the control and driving signal lines are not hardwired. That is, the connecting points are left as potential welding points. If a column driving circuit that is coupled to a particular input data line is damaged, then a redundant data driving subcircuit can be hardwired by welding the corresponding crossing points to compensate the damaged circuit. The damaged circuit is also disconnected (by using a laser cut or compatible methods) from the corresponding input data line and the internal data line as necessary.
