Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a polymer resin substrate is used in display apparatuses, then flexibility and portability are improved, but polarization occurs leading to afterimages and reduced reliability
Solution Approach 1:
A conductive layer is introduced as an intermediary between the polymer resin substrate and the barrier layer. This conductive layer prevents polarization of the polymer resin substrate by providing a charge dissipation path, thereby eliminating afterimages while maintaining the flexibility and portability benefits of the polymer substrate.
Solution Approach 2:
The electrical conductivity parameter of the substrate system is changed by introducing the conductive layer with specific conductivity characteristics. This parameter change prevents charge accumulation and polarization in the polymer resin substrate, resolving the afterimage issue while preserving mechanical flexibility.
2Reliability
If a conductive layer with boron implantation is added to prevent polarization, then reliability is improved, but device complexity increases
Solution Approach 1:
The conductive layer is merged with the existing barrier layer structure, where the barrier layer serves dual functions as both a protective barrier and a support for the conductive layer. This integration reduces the number of separate components and simplifies the overall device structure while maintaining improved reliability.
Solution Approach 2:
The barrier layer is designed to serve multiple functions: providing physical protection, supporting the conductive layer, and facilitating the boron implantation process. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.

AI summary
A method of manufacturing a display apparatus includes forming a first substrate on a support substrate; forming a first barrier layer on the first substrate; and forming a conductive layer by implanting n-type impurities or p-type impurities in the first barrier layer and at least a portion of the first substrate. A display apparatus includes a conductive layer arranged on a substrate and a barrier layer arranged on the conductive layer. The conductive layer is doped with n-type impurities when the first barrier layer is doped with n-type impurities, and the conductive layer is doped with p-type impurities when the first barrier layer is doped with p-type impurities.
