Abstract
The operation of thin-film-transistor (TFT)-addressed liquid-crystal (LC) display circuits is analyzed. The voltage on the storage capacitor in a simulated TFT-LC circuit is measured. TFT´s fabricated in our laboratory have been demonstrated to be able to function satisfactorily in a TFT-LC circuit. The storage capacitor, thus the LC cell, can be charged to desired voltages within a line time and holds the voltage for one frame time under proper bias conditions. TFT´s in a TFT-LC circuit perform differently from the dc condition. The dynamic ON current is higher and the dynamic OFF current is lower than the dc currents. Excellent dynamic stability in both on and off conditions is measured.
