Stereoscopic Display Pattern Groove Air Layer Crosstalk

The patent applies porous materials by forming air layers within the pattern grooves of the pattern layer. These air-filled porous structures replace the traditional black stripe material, allowing light to pass through while maintaining the vertical viewing angle enhancement function. The air layers create optical path differences that separate left and right eye images without absorbing light, thus improving transmittance and luminance while preserving the expanded vertical viewing angle.

The patent uses composite materials by combining the pattern layer with air layers formed inside pattern grooves. This composite structure integrates the mechanical support function of the pattern layer material with the optical function of the air layers, creating a system that enhances vertical viewing angle while maintaining high light transmittance and luminance for both 3D and 2D display modes.

The patent converts the potentially harmful light-blocking function of black stripes into a beneficial light-guiding function. By forming pattern grooves with air layers, the structure that would normally block light is transformed into an optical element that uses refraction and total internal reflection at the air-pattern layer interfaces to achieve image separation, thereby converting light loss into useful optical functionality.

The patent merges multiple functions into a single integrated structure. The pattern layer simultaneously provides mechanical support, defines the pattern geometry through its grooves, and creates the air layer optical elements. This consolidation eliminates the need for separate components for each function, reducing overall device complexity while achieving improved vertical viewing angle and reduced crosstalk.

The patent uses thin film structures for the pattern layer that can be formed using standard thin-film fabrication techniques. The pattern grooves with air layers are created within this thin film structure, maintaining flexibility in design while keeping the overall device structure simple and compatible with existing manufacturing processes.
