综述了液晶、有机电致发光及电泳显示技术的柔性显示机理及研究前沿.其中,反射式双稳态胆甾液晶和PDLC柔性显示适用于辊对辊(Roll-to-roll)连续工艺流程,但还存在响应速度较慢、驱动电压较高、对比度偏低等尚待研究解决的问题.通过聚合物墙和聚合物网络克服铁电液晶分子成近晶型排列织构易受外界压力或振动破坏的缺点,可实现铁电液晶柔性显示的高质量动画效果.具有自发光、宽视角、抗弯曲能力强等优异性能的OLED是实现柔性显示的较理想的选择.但柔性树脂基板对水、氧阻隔能力差是其实现柔性显示的瓶颈之一.EPD技术具有双稳态特点,且没有画面闪烁问题,在对响应时间要求不高的电子书、电子报等柔性显示方面具有较大的优势.
