Title:
METHOD FOR DRIVING LIQUID CRYSTAL OPTICAL SHUTTER
Document Type and Number:
Japanese Patent JPH0667158
Kind Code:
A
Abstract:
PURPOSE: To improve reproducibility in gradation representation in a liquid crystal optical shutter capable of displaying a halftone or printing the same.
CONSTITUTION: The liquid crystal optical shutter 1 is driven by applying a reset voltage (1kHz frequency and ±10 volt voltage) and a required voltage (1kHz frequency and voltage making the required optical response state π1 volt-π8 volt voltage) making a required optical response state containing the halftone to a segment transparent electrode 8 at every prescribed time (2ms and 10ms) alternately.
