The Preparation of 135° Twist Continuous Director Rotation Ferroelectric Liquid Crystal Display
|
Abstract:
When the continuous director rotation ferroelectric liquid crystal was cooled from N* phase to SmC* phase without an applied electric field, a 135° twist cell with uniform alignment and good gray scale was prepared. The contrast ratio was larger than 70, rise time reached 587 microsecond and fall time was 486 microsecond. The preparation succeed in avoiding the electric field destroy the TFT and the remainder electric charge degrade the character of the display. The cell can meet the need of high speed color display due to realizing gray scale.
