摘　　要：研制出一种反射式双稳态扭曲向列相(RBTN)液晶显示器,它既具有无后偏振片反射式显示的优点,又具有在零电压下的双稳性质。实验发现,借助于调整选择脉冲的幅值可实现两个双稳扭曲态之间的转换,这与透射式BTNLCD的情况是一样的。首次演示了RBTNLCD在-36°和324°之间的双稳性。A reflective bistable twisted nematic (BTN) liquid crystal display has been developed. It combines the advantages of truly reflective display without the rear polarizer and the bistable nature of the zero voltage state. It was found experimentally that switching between the two bistable twist states could be achieved by adjusting the magnitude of the selection voltage pulse,just like the case in transmittive BTN LCDs.In demonstrating the reflective BTN LCDs,we also show for the first time bistability between the-36°and 324° twist states.
