Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional image display devices face challenges in reducing overall thickness and preventing distortion and specific color intensiveness in image information.
Innovation Solution
A three-dimensional image display device comprising a data panel, a light supplier, a lens array, and a gap layer, where the light supplier locally radiates light to display left and right eye images, and the lens array converts Lambertian light into collimated light for viewing without distortion, with a gap layer and adhesive layers to minimize thickness and prevent aberrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a polarizing plate and specifically manufactured screen are used to display three-dimensional images, then three-dimensional image display capability is achieved, but overall device thickness increases
Solution Approach 1:
The patent extracts and removes the polarizing plate from the display system, transitioning from a polarizing-based 3D display to a lens array-based autostereoscopic display. This elimination of the polarizing plate directly reduces overall device thickness while maintaining three-dimensional image display capability through the lens array structure.
Solution Approach 2:
The patent introduces a lens array as an intermediary component between the display panel and the viewer's eyes. This lens array mediates the light paths to enable separate viewing of left and right eye images without requiring polarizing plates, thereby achieving 3D display functionality with reduced thickness.
2Length of stationary object
If components are placed in direct contact to reduce thickness, then overall thickness decreases, but image distortion and color intensiveness occur
Solution Approach 1:
The patent segments the space between the display panel and lens array by introducing a gap layer, rather than placing components in direct contact. This segmentation maintains precise optical spacing to prevent image distortion and color intensiveness while still achieving compact overall thickness through optimized component arrangement.
Solution Approach 2:
The gap layer acts as an intermediary between the display panel and lens array, maintaining precise optical spacing. This intermediary space prevents direct contact that would cause distortion while allowing the overall device thickness to remain compact through optimized component positioning.
3Stability of the object's composition
If adhesive layers are used to bond components, then structural stability is achieved, but additional thickness is added
Solution Approach 1:
The patent employs thin adhesive films to bond the gap layer to the display panel and the lens array to the gap layer. These thin film adhesive layers provide sufficient structural stability while minimizing additional thickness contribution compared to conventional bonding methods.
