Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anamorphic 3D displays provide a proper 3D effect only from a specific viewing angle due to light spreading from traditional light sources, limiting the effectiveness of 3D effects in outdoor digital advertisements.
Innovation Solution
A multi-angle display device with a lens arranged at a predetermined distance from unit pixels, ensuring light has a straight path and providing different color information per angle, using a spherical or conoscopic lens with strategically placed barriers to maintain focused light paths without spreading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional light sources are arranged for displays, then light can illuminate the display area, but light spreads due to the nature of the light source, preventing proper 3D effect from multiple viewing angles
Solution Approach 1:
A lens is introduced as an intermediary component between the light source and the display area. The lens focuses light from multiple light sources to create consistent light paths that maintain 3D effects across multiple viewing angles, resolving the contradiction between viewing angle versatility and light path consistency.
Solution Approach 2:
The patent changes the spatial parameter by positioning the lens at a specific distance from the light source (at or near the focal length). This parameter adjustment enables the lens to properly focus light and create straight light paths, transforming the light propagation characteristics to achieve both multi-angle viewing and consistent 3D effects.
2Stability of the object's composition
If light barriers are arranged close to light sources to control light spread, then light paths can be controlled, but the barriers become long and complex in structure
Solution Approach 1:
The lens serves as a mediator that replaces the need for complex light barriers. By positioning the lens at the focal length from light sources, it naturally focuses light into straight paths without requiring long barriers, thus controlling light paths while reducing structural complexity.
Solution Approach 2:
Changing the distance parameter between the lens and light source to the focal length creates optimal light focusing conditions. This parameter optimization eliminates the need for extended barrier structures, achieving light path control with minimal complexity.
3Stability of the object's composition
If a lens array with curvature is used as in Patent No. 10-0618456, then light can be focused, but the lens is separate from light sources and requires complex arrangement
Solution Approach 1:
The patent merges the lens with the light source assembly by positioning the lens immediately adjacent to or at a specific distance from each light source. This integration simplifies the overall structure compared to separate lens arrays, while maintaining effective light focusing for multi-angle 3D display.
Solution Approach 2:
The patent optimizes the distance parameter between the lens and light source to be at or near the focal length, which achieves effective light focusing with a simpler, more compact arrangement compared to traditional separated lens arrays.
