Solution Overview
Problem
Existing display devices struggle to provide high-quality three-dimensional images without the need for 3D glasses, and there is a challenge in aligning lens devices effectively with display devices to minimize image distortion.
Innovation Solution
A liquid crystal lens device with a connection layer and lens arrays is detachably connected to a display device, using complementary contact interfaces and adjustable refractive indices to enhance image refraction and alignment, allowing for high-quality 3D image output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable lens device is used for glass-free 3D display, then convenience and usability are improved, but image reliability deteriorates due to air gaps and refractive index mismatches
Solution Approach 1:
A connection layer made of transparent material with refractive index matching the lens array is introduced as an intermediary between the lens device and display device. This connection layer eliminates air gaps and refractive index mismatches that would otherwise degrade image quality, while still allowing the lens device to be detachably connected for convenience.
Solution Approach 2:
The refractive index of the connection layer is specifically matched to that of the lens array material, changing the optical parameters of the system to eliminate refraction errors at interfaces. This parameter matching ensures reliable image transmission while maintaining the detachable nature of the connection.
2Manufacturing precision
If contact interfaces are provided on the display device for lens attachment, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The connection interfaces are segmented into discrete contact regions (first contact interfaces on the display device and second contact interfaces on the lens device). This segmentation provides precise alignment points without requiring complex overall restructuring of either device, maintaining simplicity while improving alignment precision.
Solution Approach 2:
Contact interfaces are positioned in the non-display area, utilizing the peripheral dimension of the display device rather than the active display area. This dimensional relocation provides alignment features without interfering with the primary display function or requiring complex integration into the display structure.
