Electronic Apparatus Defect Concealment via Adhesive Layer Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses face challenges in preventing defects from being visually recognizable, particularly in the integration of display modules with electronic modules, where mechanical and optical issues lead to visibility of components through openings and adhesive layers.
Innovation Solution
The use of an adhesive layer between the display module and cover glass with strategically designed openings, along with a protective layer and a print layer for light reflection, helps in concealing defects and improving the reliability of the electronic apparatus by spacing the electronic module away from the adhesive layer and minimizing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electronic module is disposed close to the display module for compact integration, then device compactness is improved, but defects become visually recognizable through openings and adhesive layers
Solution Approach 1:
A light blocking layer is introduced as an intermediary between the electronic module and the adhesive layer. This layer prevents light from reflecting off the electronic module components and becoming visible through the adhesive layer and cover glass, thereby concealing defects while maintaining compact integration. The light blocking layer acts as a mediator that eliminates the harmful visual effect without increasing device volume.
2Ease of operation
If openings are provided in the adhesive layer for electronic module integration, then component accessibility is improved, but mechanical strength and optical uniformity deteriorate
Solution Approach 1:
The adhesive layer is designed with non-uniform properties: it has openings in specific locations to allow electronic module integration and component accessibility, while maintaining continuous adhesive coverage in other areas to preserve mechanical strength. The light blocking layer is selectively applied only in regions where electronic modules are disposed, providing local defect concealment without affecting the overall structural integrity of the adhesive layer.
3Illumination intensity
If the adhesive layer is made transparent for optical clarity, then light transmission is improved, but defect visibility increases
Solution Approach 1:
The optical system is segmented into multiple functional layers: a transparent adhesive layer for light transmission and a separate light blocking layer for defect concealment. This segmentation allows each layer to perform its specific function optimally - the adhesive layer maintains optical clarity while the light blocking layer selectively prevents light reflection from electronic module components, thereby hiding defects without compromising overall light transmission for the display area.
