Ferroelectric liquid-crystal video display
1989
Although the surface stabilized ferroelectric liquid-crystal (SSFLC) effect is bistable, the possibility of creating a wide range of grayscales based on the multidomain structure is demonstrated. An active-matrix-addressed SSFLC black-and-white television display was realized, proving the grayscale capability. The active-matrix-addressed liquid-crystal TV based on the SSFLC effect shows a superior optical performance compared to the twisted nematic liquid-crystal TV. Its high contrast is almost viewing angle independent; switching speed is high, and flicker is absent. The disadvantages lie in the more difficult technology (cell thickness, SSFLC orientation, high-temperature liquid-crystal handling shock-sensitivity). >
