Light Guide Plate Laminate Reduced Pressure Gap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple light guide plates are stacked, maintaining a uniform gap between them is challenging, which can lead to color shifts and decreased resolution in video display.
Innovation Solution
A light guide plate laminate is proposed, where at least a pair of light guide plates are stacked with a space between them in a state of reduced pressure, typically 90 kPa or less, to maintain uniformity and prevent warpage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light guide plates are stacked, then full-color video display capability is improved, but gap uniformity deteriorates leading to color shifts and resolution decrease
Solution Approach 1:
The patent applies parameter changes by controlling the pressure parameter within the stacked light guide plate structure. By maintaining a reduced pressure state (below atmospheric pressure) in the space between light guide plates, the plates are pulled together uniformly, ensuring consistent gap uniformity across the entire stacked structure while enabling full-color video display capability through multiple plates
Solution Approach 2:
The patent creates an inert environment by establishing a reduced pressure atmosphere within the light guide plate stack. This controlled pressure environment prevents warpage and maintains structural stability, allowing the multiple light guide plates to remain uniformly positioned without color shifts or resolution degradation
2Adaptability or versatility
If multiple light guide plates are stacked, then video display functionality is improved, but warpage increases reducing mechanical reliability
Solution Approach 1:
The patent changes the pressure parameter to a reduced state below atmospheric pressure, which creates a uniform compressive force across the stacked light guide plates. This parameter control prevents warpage deformation and maintains mechanical reliability while preserving the enhanced video display functionality achieved through stacking multiple plates
