Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional driving methods are used for light-emitting elements, then the structure remains simple, but the light emission efficiency and output are insufficient
Solution Approach 1:
The patent combines the light-emitting element and thyristor into a single integrated structure on the same substrate, with shared electrode connections. The thyristor's control electrode is connected to the light-emitting element's electrode, creating a merged functional unit that improves light emission efficiency while managing complexity through integration rather than separate components
Solution Approach 2:
The patent changes the electrical parameters of the driving circuit by introducing thyristors that can control the current flow to light-emitting elements. This allows dynamic adjustment of operating parameters (current, voltage) to optimize light emission efficiency, transforming the static driving approach into a controllable parameter-based system
2Power
If existing thyristor configurations are used, then the device structure is maintained, but the light output enhancement is limited
Solution Approach 1:
The patent transitions from planar two-dimensional semiconductor structures to three-dimensional stacked semiconductor layers. Multiple semiconductor layers are stacked vertically to form the thyristor structure, enabling enhanced light output through increased active volume and improved current distribution, while the stacking approach manages manufacturing precision requirements through layered fabrication processes
