Engineering Contradiction Analysis
1Volume of moving object
If the size of light emitting devices is reduced to very small dimensions, then the display resolution and density are improved, but the arrangement and control of terminals for leading wires becomes impossible
Solution Approach 1:
The patent merges the IC and its input structure into a single integrated component. The IC main body is directly formed on the light emitting structure, and the IC input terminals are integrated with the light emitting unit input terminals, eliminating the need for separate terminal arrangements and wire connections that would be impossible at very small scales.
Solution Approach 2:
The IC is nested directly on the light emitting structure, with the IC main body formed on the light emitting unit layer. The IC input terminals are nested with the light emitting unit input terminals, creating a compact hierarchical structure that enables control of miniaturized light emitting devices.
2Extent of automation
If traditional separate IC and terminal arrangement methods are used, then the control functionality is achieved, but the device complexity and manufacturing difficulty increase when scaling down
Solution Approach 1:
The patent combines multiple functions into unified structures: the IC input terminals are merged with the light emitting unit input terminals, and the IC is directly formed on the light emitting structure. This integration simplifies the overall device structure and reduces manufacturing complexity while maintaining full control functionality.
Solution Approach 2:
The input terminals serve dual functions: they act as both IC input terminals for controlling the IC and as light emitting unit input terminals for driving the light emitting devices. This multi-functionality reduces the number of separate components and simplifies the terminal arrangement structure.
3Extent of automation
If conventional wire leading methods are used, then the light emitting devices can be controlled, but the manufacturing precision and reliability deteriorate at very small scales
Solution Approach 1:
The patent replaces mechanical wire leading and physical terminal connections with a direct semiconductor fabrication approach. The IC is formed using semiconductor processes directly on the light emitting structure, and electrical connections are established through integrated conductive paths, eliminating the need for precise mechanical wire placement and connection that becomes impossible at very small scales.
Solution Approach 2:
The invention changes the fundamental parameter of connection method from mechanical/wire-based to semiconductor-fabrication-based. By transitioning to direct formation of the IC and its terminals through semiconductor processes, the manufacturing precision requirement shifts from mechanical alignment to semiconductor-level fabrication, which is well-established and reliable.
