— Various kinds of errors in pixel voltage are considered, using computer simulation for the design of 15-in.-diagonal full-color TFT-LCDs. Adopting the advanced capacitively coupled driving method with a double-scanning gate pulse for TFT-LCD driving, satisfactory display characteristics are confirmed by experiments on fabricated models.

Abstract A TFT array having 476 × 630 (299 880) pixels employing a-Si TFT with TaOx/SiNx double insulating layers is developed for a 6-inch diagonal LCD display panel. The panel is driven by a progressive scanning method for which the address time is 30 μs. The parameters of this TFT array were determined by computer simulation, and as a result of this, highly improved driving and viewing characteristics were obtained.
