Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional quantum-dot optical film is used, then the film can be integrated into display products, but the film suffers from adhesion problems with other optical layers and is prone to scratching
Solution Approach 1:
The patent applies composite materials by combining a quantum-dot optical film with a protective film having different surface energy than the quantum-dot film. This composite structure resolves the adhesion problem between optical layers while the protective film provides scratch resistance, eliminating both harmful effects identified in the contradiction.
2Length of moving object
If the optical module is slimmed down, then the display product becomes thinner, but the compatibility and assembly yield of optical films within compressed modules is affected
Solution Approach 1:
The patent changes the surface energy parameter of the optical film system by introducing a protective film with different surface energy characteristics. This parameter change enables the slimmed-down optical module to maintain compatibility and assembly yield despite the reduced thickness, as the surface energy modification affects adhesion and assembly properties.
3Illumination intensity
If the surface of quantum-dot optical film is made smooth, then the film has good optical properties, but the surface can be scratched easily and exhibits static electricity issues
Solution Approach 1:
The patent introduces a protective film as an intermediary layer between the quantum-dot optical film and the external environment. This intermediary layer provides scratch resistance and antistatic properties while allowing the underlying quantum-dot film to maintain its smooth surface and good optical properties, thus resolving the contradiction without compromising either side.
