Solution Overview
Problem
Conventional stereoscopic displays, including LED screens, face issues with visual fatigue and incompatibility with flat panel displays due to reflection from cylindrical lenses, leading to decreased contrast and saturation.
Innovation Solution
A large stereoscopic screen with cylindrical lenses integrated into light-emitting pixels, allowing each pixel to transmit left and right images differently, eliminating the need for glasses and maintaining high definition and compatibility with flat panel displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cylindrical lens plate is arranged in front of the large LED stereoscopic screen, then naked-eye stereoscopic display is realized, but the contrast and saturation of the display decrease due to serious reflection on the lens plate
Solution Approach 1:
The patent divides the large LED screen into multiple sub-modules, each containing its own cylindrical lens. This segmentation eliminates the need for a single large lens plate, reducing reflection issues while maintaining stereoscopic display functionality across the entire screen surface.
Solution Approach 2:
The patent integrates the cylindrical lens directly with each LED light-emitting unit, merging the lens function into the pixel structure itself. This combination eliminates the separate lens plate that causes reflection, while preserving the stereoscopic effect through the optical properties of the integrated lenses.
2Adaptability or versatility
If conventional stereoscopic shutter glasses are used, then stereoscopic display is achieved, but visual flashes and visual fatigue occur due to fast switching of images perceived by left and right eyes
Solution Approach 1:
The patent replaces the mechanical shutter system in conventional glasses with a passive optical system using cylindrical lenses. This substitution eliminates the fast switching mechanism that causes visual fatigue, while still achieving stereoscopic display through the directional light transmission properties of the lenses.
3Adaptability or versatility
If a cylindrical lens plate is used for large LED stereoscopic screen, then stereoscopic effect is achieved, but the device complexity increases due to the additional lens plate component
Solution Approach 1:
The patent combines the cylindrical lens functionality directly into each LED pixel module, merging what would be a separate lens plate component into the existing pixel structure. This integration reduces device complexity by eliminating additional components while maintaining the stereoscopic effect.
