Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display technologies face challenges in providing effective impact protection and contrast enhancement for light-emitting displays, often requiring complex solutions like secondary optics and louvers, which can increase costs and complexity.
Innovation Solution
A face covering structure with a mogul array and light-emitting openings is used, providing impact protection and enhanced contrast by shading LEDs and allowing light to pass through, while eliminating the need for traditional louvers and secondary optics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional louvers and secondary optics are used for impact protection and contrast enhancement, then impact resistance and contrast are improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple functions (impact protection, light guiding, contrast enhancement, and shading) into a single integrated face cover structure. The face cover includes moguls with light-emitting openings that simultaneously provide impact resistance and optical control, eliminating the need for separate louvers and secondary optics components.
Solution Approach 2:
The face cover serves multiple functions: it acts as a protective cover against impacts, provides light guiding through its mogul structure, enhances contrast by shading non-emitting areas, and controls light emission patterns. This multi-functional design replaces what would traditionally require multiple separate components.
2Illumination intensity
If traditional louvers and secondary optics are used for contrast enhancement, then contrast is improved, but device complexity increases
Solution Approach 1:
The face cover integrates contrast enhancement functionality directly into its structural design. The moguls are shaped to provide shading for non-emitting areas while allowing light to pass through designated openings, combining the functions of traditional louvers and contrast enhancement optics into a single component.
Solution Approach 2:
The face cover features localized shading structures (moguls) positioned specifically over non-emitting areas to enhance contrast, while maintaining light transmission in emitting areas. This localized approach provides contrast enhancement only where needed without adding complexity across the entire display structure.
3Device complexity
If a simple face cover structure is used, then device complexity is reduced, but impact protection and contrast enhancement may be insufficient
Solution Approach 1:
The face cover incorporates mogul structures with curved surfaces that provide both structural strength for impact resistance and optical control for light guiding and contrast enhancement. The curved geometry of the moguls helps distribute impact forces while maintaining the necessary optical properties.
4Device complexity
If a simple face cover structure is used, then device complexity is reduced, but contrast enhancement may be insufficient
Solution Approach 1:
The face cover features localized shading structures (moguls) positioned specifically over non-emitting areas to enhance contrast, while maintaining light transmission in emitting areas. This localized approach provides contrast enhancement only where needed without adding complexity across the entire display structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The face covering structure effectively protects LEDs from impacts and enhances contrast without additional components, meeting industry standards for impact resistance and viewing angles in a single, simple design.
Implementation Method 1
The face cover provides shading of the light-emitting elements of the display module, similar to louver blades in conventional displays
Implementation Method 2
a set of one or more light-emitting openings in each mogul, each positioned relative to a corresponding one or more of the light-emitting elements to permit light emitted from the corresponding one or more of the light-emitting elements to pass through the mogul
