The process is now fairly reproducible, and the transistor characteristics in the matrix are good. The arrays constructed included isolated transistor patterns from which it was established that low leakage devices could be deposited with good yield and uniformity. Interconnected arrays of devices were also made with similar encouraging results; these are possibly the largest integrated circuits ever made. Conventional EL-phosphor lamps have been driven with state-of-the-art TFTs and the transfer characteristics are satisfactory. In an appendix, a new model for the deterioration of ac-electroluminescence is proposed. (Author)
