Thin film transistor-addressed display device
Abstract
The achievement of operational 6 x 6 inch 30 lpi dot matrix displays is reported. The addressing is accomplished using thin-film transistor matrices and the display medium is ac-electroluminescence. The panel was operational over all its area, but the quality needs to be improved before it is comparable to the near perfect 20 lpi panels fabricated. A good method for interconnecting was developed using a solder bonded PC board. Greater than 75% active lit area was achieved on several displays through a second level electroding process. Further progress towards improved defect free operation can be expected.
