Display Window Module UV Pattern Invisibility via Cover Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in aesthetically enhancing the non-display areas, such as bezel regions, which often obstruct the visibility of internal components and logos due to the presence of UV pattern layers that can detract from the visual appeal.
Innovation Solution
A display device design incorporating a window module with a UV pattern layer, a cover layer, and a logo layer, where the UV pattern layer and cover layer have high light transmittance, and the logo layer is strategically positioned to minimize exposure of the UV pattern layer, thereby improving the aesthetic appearance by ensuring the UV pattern layer is not visible to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a UV pattern layer is applied to the non-display area, then the structural integrity and protection of internal components is improved, but the aesthetic appearance deteriorates due to visible patterns
Solution Approach 1:
A cover layer is introduced as an intermediary element between the UV pattern layer and the external environment. This cover layer has high light transmittance (about 0.9 or more) which allows it to block the visibility of the UV pattern layer while maintaining light transmission for the display area, thus resolving the contradiction between protection and aesthetics
Solution Approach 2:
The cover layer is designed with specific optical properties including high light transmittance and appropriate thickness to control light interaction. By optimizing the optical characteristics of the cover layer, the UV pattern layer becomes invisible while still providing structural protection, achieving both reliability and aesthetic appearance
2Shape
If the cover layer thickness is increased to block UV pattern visibility, then aesthetic appearance is improved, but light transmittance may deteriorate
Solution Approach 1:
The thickness of the cover layer is optimized within a specific range to achieve the desired balance. The cover layer thickness is controlled to be greater than the maximum thickness of the UV pattern layer (to ensure complete coverage and invisibility) but less than the maximum thickness of the first color layer (to maintain adequate light transmittance). This parameter optimization resolves the contradiction between aesthetic appearance and light transmittance
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 enhances the aesthetic appeal of the display device by maintaining high light transmittance while preventing the UV pattern layer from being seen, thus improving the visual impact of the logo and reducing potential deterioration of the aesthetic sense.
Implementation Method 1
Each of the UV pattern layer and the cover layer may have light transmittance of about 0.9 or more
