Light Guide Plate Deflector Orientation for Curved Stereoscopic Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light guide elements can only present stereoscopic images as a straight line from the incidence surface to the opposing surface, limiting the display to linear projections and failing to achieve curved or angled line presentations.
Innovation Solution
A light guide plate with deflectors arranged in rows parallel to the incidence surface, where each row's reflection surfaces are oriented in the same direction but change with distance, allowing for the presentation of curved or angled lines by adjusting the angle of reflection surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light guide plate uses a conventional structure with uniform deflectors, then the manufacturing is simple, but the display is limited to straight lines only
Solution Approach 1:
The patent applies local quality by varying the orientation of reflection surfaces in deflectors based on their position. Specifically, deflectors at different distances from the incidence surface have reflection surfaces oriented at different angles, allowing the light guide plate to display curved or angled lines rather than only straight lines. This localized variation in deflector orientation enables diverse display patterns while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the light guide plate presents stereoscopic images as straight lines only, then the structure is simple, but the visual effect is limited
Solution Approach 1:
The patent implements parameter changes by varying the orientation angle of reflection surfaces in deflectors based on their distance from the incidence surface. By changing this geometric parameter systematically, the light guide plate can present various display patterns including curved lines and angled lines, thereby achieving diverse stereoscopic display effects without requiring fundamentally different structural components.
3Adaptability or versatility
If all reflection surfaces are oriented in the same direction, then the manufacturing is easy, but curved or angled line display cannot be achieved
Solution Approach 1:
The patent applies local quality by varying the orientation of reflection surfaces in deflectors based on their position. Specifically, deflectors at different distances from the incidence surface have reflection surfaces oriented at different angles, allowing the light guide plate to display curved or angled lines rather than only straight lines. This localized variation in deflector orientation enables diverse display patterns while maintaining a relatively simple overall structure.
