Manufacturing methods and engineering for TFT addressed display

This is the Fifth Quarterly Report on Contract DAAB07-76-C-0027; Manufacturing Methods and Technology Evaluation for the fabrication of this film transistor based solid state displays. This quarter was one of major accomplishments. First, a substrate was fabricated which was virtually perfect over half the total display area. The primary defect in the inoperable area was identified as open busses due to cracked crossover insulators. As the result of corrective action taken to resolve this problem, the next run produced the excellent half panel. This is not only the best quality display made on the pilot equipment to date, it is comparable in quality to the best displays made on the X-Y equipment. Early indications are that the fabrication of this display is not an isolated event but the beginning of a period of improved production performance.
