1Illumination intensity
If conventional polarizing glasses with uniaxial retardation layers are used for stereoscopic display, then polarization control is achieved, but wavelength dispersion characteristics deteriorate leading to poor viewing angles
Solution Approach 1:
The polarizing glasses are divided into a first region and a second region, each with different uniaxial retardation layers having opposite signs. This segmentation allows different parts of the glasses to handle different wavelength ranges, improving overall wavelength dispersion characteristics while maintaining polarization control for stereoscopic viewing.
Solution Approach 2:
Different regions of the polarizing glasses are assigned different optical properties (uniaxial retardation layers with opposite signs) to optimize performance for specific viewing angles and wavelength ranges. This local differentiation improves wavelength dispersion characteristics without compromising overall polarization control.
2Adaptability or versatility
If uniaxial retardation layers are used in polarizing glasses, then polarization states are controlled, but viewing angles (upper, lower, left, right) are limited
Solution Approach 1:
The polarizing glasses are segmented into multiple regions with different uniaxial retardation layers oriented at different angles. This allows each region to optimize polarization control for specific viewing directions, thereby expanding the overall viewing angle range while maintaining image quality across all directions.
Solution Approach 2:
The uniaxial retardation layers in different regions are configured with asymmetric orientations (different angles) to match the asymmetric viewing requirements. This asymmetric configuration enables the glasses to provide optimized performance for upper, lower, left, and right viewing angles simultaneously.
