提出一种双层交错结构的驱动电极控制液晶分子偏转的可控液晶光栅.利用光刻和镀膜工艺在玻璃基板上制作掺铝氧化锌-二氧化硅-掺铝氧化锌双层交错结构的驱动电极, 采用液晶成盒工艺将制备好的驱动电极基板和公共电极基板组装成液晶盒.与传统单层控制电极相比, 双层交错电极实现了基板的无缝覆盖, 避免了各电极存在的空白区, 使得器件的控制区域变得完整与灵活.光学显微镜测试表明, 掺铝氧化锌第一电极和第二电极的宽度为275.8, 两者之间通过SiO2介质层隔离并相互交错覆盖在玻璃基板上.结合液晶光栅驱动电路, 可控液晶光栅能有效地控制遮光区与透光区的比值, 实现不同3D视差图片在同一套系统中的实时切换播放, 在多视点3D实时切换显示领域有一定的应用前景.

A viewpoint controllable liquid crystal grating was presented, which was driven by two-layer staggered electrodes to control the deflection of liquid crystal molecules. AZO-SiO2-AZO driving electrodes with two-layer staggered structure were prepared on the glass substrate using lithography and vacuum coating technology. This grating avoids the blank area between the single-layer electrodes and expands the control area. Therefore the control area becomes complete and flexible. The optical images shows AZO electrodes and AZO electrodes with the width of 275.8are parallel interdigitated and isolated by SiO2 insulation layer on the glass substrate. Combining the drive circuit, the liquid crystal grating could control the ratio of the light shielding area and transmission area effectively. It has some application prospects in the field of three-dimensional display
