Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional light emitting components use standard thyristor structures, then the light emission can be controlled, but high voltage is required and power consumption increases
Solution Approach 1:
The patent changes the bandgap parameter of the thyristor structure by introducing a voltage reducing layer with smaller bandgap than the light emitting layer. This parameter change allows the thyristor to operate at lower voltages while maintaining reliable light emission control, directly reducing power consumption without sacrificing control reliability
2Reliability
If high voltage is applied to thyristors to ensure they are in ON state, then light emission control is reliable, but power consumption increases
Solution Approach 1:
The voltage reducing layer changes the electrical parameter characteristics of the thyristor by providing a lower bandgap path for carrier flow. This allows the thyristor to maintain reliable ON state at reduced voltage levels, thereby reducing energy consumption while preserving operational reliability
3Device complexity
If standard bandgap materials are used in thyristors, then the structure is simple, but voltage reduction and power consumption optimization are limited
Solution Approach 1:
The patent employs composite material structure by combining a voltage reducing layer with smaller bandgap and a light emitting layer with larger bandgap in a laminated configuration. This composite structure achieves voltage reduction and power consumption optimization while maintaining relatively simple fabrication processes and device architecture
