Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light guide plate technologies for enhancing realism in illuminated displays do not effectively conceal their reflective techniques, limiting the observer's sense of immersion.
Innovation Solution
A light guide plate with a transparent panel featuring a plurality of prisms on one surface, where the orientation of the prisms' reflection surfaces is adjusted according to local regions corresponding to specific tones, creating a metallic texture by varying brightness and reflection angles to simulate an uneven metallic surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If reflection patterns are established to improve three-dimensional perception, then the sense of realism is improved, but the technique becomes visible and reduces immersion
Solution Approach 1:
The patent applies local quality by varying the orientation of reflection surfaces in different local regions corresponding to different tones. Each local region has prisms with reflection surfaces oriented according to the specific tone requirements, creating a metallic texture effect that is perceptually realistic without revealing the underlying technical structure.
Solution Approach 2:
The patent transforms the two-dimensional reflection pattern into a three-dimensional metallic texture perception by orienting reflection surfaces at different angles. This dimensional transformation allows the light guide plate to simulate the appearance of an uneven metallic surface, enhancing realism while concealing the technical implementation.
2Manufacturing precision
If reflection surfaces are oriented to simulate metallic texture, then the metallic perception is improved, but the structure becomes more complex
Solution Approach 1:
The patent implements local quality by assigning specific orientation angles to reflection surfaces in different local regions. Each region's prisms are oriented according to the tone requirements, creating a realistic metallic texture effect while managing structural complexity through localized optimization rather than uniform complexity throughout.
