Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the organic material layer is improved to increase luminous efficiency, then the efficiency is increased, but the driving voltage is relatively decreased which causes Joule heating and reduces lifespan
Solution Approach 1:
The patent changes the chemical structure parameters of the organic material by introducing specific substituents (fluorene, carbazole, triphenylamine groups) to optimize the balance between luminous efficiency and thermal stability, allowing high efficiency without excessive Joule heating
Solution Approach 2:
The patent creates a composite organic material structure combining multiple functional groups (fluorene core with carbazole and triphenylamine substituents) to achieve synergistic effects that simultaneously improve luminous efficiency and thermal stability, resolving the contradiction between efficiency and lifespan
2Area of stationary object
If larger displays are implemented to meet market trends, then the display size is increased, but the power consumption is increased which affects battery life
Solution Approach 1:
The patent optimizes the molecular weight and structural parameters of the organic material to achieve appropriate charge carrier mobility and energy levels, enabling larger displays to operate at lower voltages and reduce power consumption
Solution Approach 2:
The patent develops organic materials that can be deposited in thin films, reducing the amount of material needed and enabling larger area coverage with controlled power consumption through efficient charge transport
3Reliability
If multiple organic material layers are used to improve efficiency and stability, then the element performance is improved, but the device complexity is increased
Solution Approach 1:
The patent designs the organic material with multiple functional groups that can perform different functions (charge transport, hole injection, stability enhancement) within a single material system, reducing the need for multiple separate layers while maintaining performance
