Liquid Crystal Grating for Adjustable 3D Display Orientation

The patent applies the dynamics principle by transforming the fixed grating structure into a dynamic, adjustable structure. The liquid crystal grating can change its slit positions and orientations in response to different driving signals, enabling the system to adapt between landscape and portrait viewing orientations. This dynamic adjustment capability resolves the contradiction by allowing the grating to reconfigure itself rather than requiring multiple fixed gratings.

The patent employs parameter changes by modifying the electrical parameters (voltage signals) applied to the liquid crystal material to change the physical parameters (slit positions and orientations) of the grating. By varying the driving signals, the grating can switch between different configurations suitable for landscape and portrait modes, thus achieving multi-orientation adaptability without increasing structural complexity.

The patent applies universality by designing the electrode arrangement to perform multiple functions. The crossing bar-like electrodes can generate different grating patterns and slit positions depending on which electrodes are activated and how they are driven. This multi-functional electrode structure eliminates the need for separate electrode sets for different orientations, achieving slit position adjustability without proportionally increasing complexity.

The patent uses segmentation by dividing the electrode system into multiple independent bar-like electrodes that can be controlled separately. This segmentation allows selective activation of electrode groups to create different grating configurations, providing flexible slit position adjustment while maintaining a relatively simple overall electrode structure compared to fully customized patterns.
