目前的液晶显示器件(LCD)主要是以扭曲向列(TN)型器件为主。由于它的响应速度慢(数十毫秒——数百毫秒),并已接近极限的程度,而强介电性液晶具有存储性(双稳态特性)和毫秒以下的高速响应特性,最适于大容量显示。所以对强介电性液晶及器件的研究已受到各国液晶工作者的高度重视,并作为新一代液晶材料和器件积极加以开发。最近相继试制成功采用强介电性液晶的打印机头的光开关(光阀)阵列和大容量的点矩
The current liquid crystal display (LCD) is mainly twisted nematic (TN) -type devices. Due to its slow response speed (tens of milliseconds to hundreds of milliseconds) and nearing extremes, ferroelectric liquid crystal has storage (bistable characteristics) and high-speed response characteristics of milliseconds or less, and is most suitable for Large capacity display. Therefore, research on ferroelectric liquid crystal and devices has been highly valued by liquid crystal workers in various countries and is actively developed as a new generation of liquid crystal materials and devices. Recently successfully trial-and-succeeded using ferroelectric liquid crystal printer head optical switch (light valve) array and large-capacity moment
