Abstract :
Summary form only given. As the display size increases, and as the resolution gets higher, the gate-line delay problem and the yield of the panel becomes more important. Double-layered gate insulators such as Ta 2O5/SiN or Al2O3/SiN have been proposed and used in products. The Al-gate TFT (thin-film transistor) reduces gate-line delay and enhances production yield. With this Al-gate TFT, conventional design rules can achieve a diagonal size of over 30 in and resolution of over 1 Mpixel
