Decorative Component Blackout Effect via Colored Transparent Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative components with internal light sources face challenges in achieving a uniform blackout effect when the light is off, as light diffusing layers tend to stand out and make it difficult to conceal the display elements from view.
Innovation Solution
Incorporating a sensor sheet with a colored transparent layer and a light diffusing layer, where the colored transparent layer has a transmittance of 10% to 70% and the light diffusing layer has a transmittance of 2.0% or higher, both with uneven surfaces, to ensure the display elements are integrated with the surroundings when the light is off and emit uniform light when on.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light diffusing layer with white coating is provided to achieve uniform illumination, then the illumination quality is improved, but the blackout effect deteriorates because the light diffusing layer stands out when the internal light source is off
Solution Approach 1:
The patent applies local quality by differentiating the properties of different layers: the light diffusing layer uses a transparent resin with specific roughness (Ra 0.03-0.5μm) for light diffusion, while the colored transparent layer provides selective light absorption and blackout effect. Each layer has optimized local properties to fulfill its specific function without compromising the other.
Solution Approach 2:
The patent employs composite materials by combining a light diffusing layer (transparent resin with controlled roughness) and a colored transparent layer (with specific transmittance 10-70%) to create a multi-layer structure that simultaneously achieves uniform illumination and effective blackout, resolving the contradiction between the two opposing requirements.
2Illumination intensity
If the colored transparent layer has high transmittance to allow bright illumination, then the illumination quality improves, but the blackout effect deteriorates
Solution Approach 1:
The patent applies parameter changes by optimizing the transmittance of the colored transparent layer within a specific range (10-70%) and controlling the surface roughness of the light diffusing layer (Ra 0.03-0.5μm). These parameter optimizations enable the system to achieve both bright uniform illumination and effective blackout, resolving the contradiction between brightness and concealment.
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 solution effectively achieves a blackout effect where the display elements become inconspicuous when the internal light source is off while maintaining bright and uniform illumination when it is on, enhancing the aesthetic and functional properties of the decorative components.
Implementation Method 1
a light diffusing layer that exposes, towards an internal light source side, a surface formed having an uneven surface
Implementation Method 2
a colored transparent layer formed so as to have a color tone that creates a blackout in which the display element becomes integrated with the light shielding portion surrounding the display element when the internal light source is off
