ACTIVE MATRIX LIQUID CRYSTAL DISPLAY DEVICES |
摘要 |
In an active matrix LC display device having an array of display elements (12) addressed via respective transistors (11) connected to sets of row address conductors (14) to which selection pulses are applied in sequence and column address conductors (16) to which data signals are applied, and a storage capacitor (18) connected between each display element and a row conductor adjacent that to which its associated transistor is connected and which is operable in a capacitive coupling drive mode in which a step level in the waveform applied to each row conductor contributes to the final display element voltage, the row drive waveform applied to each row conductor includes a step level both before and after the selection pulse. Through this, the vertical scanning direction used can readily be reversed and an advantageous dot - inversion drive scheme can be employed.
