Abstract :
A poly-Si TFT (thin-film transistor) defect-tolerant scanner for large-area AMLCD (active-matrix liquid-crystal displays) is described. The scanner consists of regular and spare delay circuits, error correcting circuits, transfer switches, exchange switches, and output buffers. An 8-stage prototype scanning circuit on a quartz substrate uses a low-temperature (>
