The proposed patterned polarizer rather than the conventional ±λ/4 polarizer can further reduce the crosstalk through its corresponding glass for stereoscopic LCDs and can be fabricated by using the same patterned alignment technique. The patterned polarizer comprises a linear polarizer, a patterned retarder and a biaxial film. The maximum crosstalk ratio of the optimal design is reduced from 0.1 (for the conventional circular polarizer using ±λ/4 retarder and positive C film) to 0.016 (for the proposed structure) at ±60° viewing cone for the light obliquely passing through both the glasses and the LCD at the same angle. As to the light normally passing through both the LCD and glasses, the maximum crosstalk ratio can be reduced from 0.0167 to 0.0126 with rotated glasses.
所提出的图案化偏振器而非传统的±λ/4偏振器，可以通过其对应的玻璃进一步降低立体液晶显示器的串扰，并且可以通过使用相同的图案化取向技术来制造。该图案化偏振器包括线性偏振器、图案化延迟器和双轴膜。对于以相同角度倾斜穿过玻璃和液晶显示器的光，在±60°视角锥下，优化设计的最大串扰比从0.1（对于使用±λ/4延迟器和正C膜的传统圆偏振器）降低到0.016（对于所提出的结构）。对于垂直穿过液晶显示器和玻璃的光，通过旋转玻璃，最大串扰比可以从0.0167降低到0.0126。
