Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereoscopic display devices restrict 3D image viewing to frontal angles, preventing users from seeing stereo images at oblique angles and failing to create a vivid effect of images floating in mid-air.
Innovation Solution
Integration of a stereoscopic display device with a three-layer structure comprising a flat panel display, a lens array layer, and a microstructure layer into electronic products, allowing light field adjustment and light direction modulation to enable 3D image viewing at oblique angles, creating the illusion of images floating in mid-air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional binocular vision imaging technology is used for stereoscopic display, then stereo images can be displayed, but users can only view them at frontal angles and not at oblique angles
Solution Approach 1:
The patent transitions from conventional 2D display to 3D stereoscopic display by adding depth dimension through lens array and microstructure layers. This enables light to be modulated in multiple directions, allowing users to view stereo images at both frontal and oblique angles simultaneously, thus expanding the viewing angle range while maintaining viewing convenience
Solution Approach 2:
The display device is segmented into multiple functional layers: flat panel display layer, lens array layer, and microstructure layer. Each layer performs a specific function - the flat panel displays the base image, the lens array separates light into different viewing directions, and the microstructure layer further modulates light direction. This segmentation enables the system to achieve multi-angle viewing capability
2Adaptability or versatility
If conventional stereoscopic display devices provide visual stimuli in only one direction, then the display structure is simple, but they cannot provide a vivid sensation that the image is escaping from the confines of a plane
Solution Approach 1:
The patent adds visual directionality by enabling light to escape in multiple directions (both upward and forward) rather than just one direction. The lens array and microstructure layers work together to modulate light in three-dimensional space, creating the vivid sensation that images are floating in mid-air by controlling light propagation in multiple spatial dimensions
Solution Approach 2:
The display device uses a composite structure combining flat panel display, lens array, and microstructure layer. This composite design integrates multiple materials and structures with different optical properties to achieve complex light modulation functionality, enabling multi-directional visual stimuli while managing the inherent structural complexity through systematic integration
