Solution Overview
Problem
Display devices suffer from glare and reduced contrast due to light reflection from metal layers, affecting display quality.
Innovation Solution
An electronic device with a substrate and a driving component featuring a first electrode and a first optical adjustment unit, where the optical adjustment unit has an opening to expose the electrode surface, and an electronic component is electrically connected to the driving component through this opening, reducing reflection by using an insulation layer and a metal layer with specific thickness ratios to minimize glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal layer is used in the display device, then electrical conductivity and structural strength are improved, but light reflection increases causing glare and reduced contrast
Solution Approach 1:
The patent applies composite materials by combining multiple layers including metal layers, insulation layers, and optical adjustment units with specific refractive indices. This composite structure reduces light reflection through optical interference while maintaining the electrical conductivity function of the metal layer, thereby resolving the contradiction between conductivity and glare reduction.
Solution Approach 2:
The patent introduces an optical adjustment unit as an intermediary layer between the metal layer and the external environment. This unit with specifically controlled refractive index acts as a mediator that reduces the optical contrast difference, thereby minimizing light reflection and glare while allowing the metal layer to maintain its electrical function.
2Reliability
If the metal layer thickness is increased to improve conductivity, then electrical performance is improved, but light reflection and glare are intensified
Solution Approach 1:
The patent applies parameter changes by precisely controlling the thickness of the metal layer and the refractive index of the optical adjustment unit. By optimizing these parameters, the patent achieves sufficient electrical conductivity with minimal metal thickness, thereby reducing light reflection and glare while maintaining electrical performance.
3Ease of manufacture
If conventional electrode structures are used, then manufacturing simplicity is maintained, but display quality is reduced due to glare
Solution Approach 1:
The patent applies segmentation by dividing the electrode structure into multiple functional layers: a metal layer for conductivity, an insulation layer for electrical isolation, and an optical adjustment unit for glare reduction. This segmented approach maintains manufacturing simplicity through sequential layer deposition while significantly improving display quality by addressing glare independently.
