Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inorganic insulating layers are used in the display panel, then the insulation performance and stability are improved, but the bendability and flexibility deteriorate
Solution Approach 1:
The patent applies local quality by using organic insulating layers specifically in the first organic area located in the display area, while other areas may use different materials. This localized application of organic materials with small Young's modulus improves bendability in the display region without compromising insulation performance in other areas.
Solution Approach 2:
The patent employs composite materials by combining organic insulating layers with other materials in the display panel structure. The organic insulating layers are integrated between the active layer and planarization layer, creating a composite structure that achieves both good insulation performance and enhanced bendability through the complementary properties of different materials.
2Manufacturing precision
If the display panel structure is made rigid for stability, then the manufacturing precision and reliability are improved, but the bendability and flexibility deteriorate
Solution Approach 1:
The patent implements local quality by introducing organic insulating layers with small Young's modulus specifically in the display area between the active layer and planarization layer. This localized softening enables the panel to bend flexibly in the display region while maintaining structural stability and manufacturing precision in other areas through the overall panel design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution improves the bendability of the display panel while preventing crack spread in inorganic materials, ensuring a stable and flexible display effect.
Implementation Method 1
Since the Young's modulus of the organic material is relatively small and the bendability of the organic material is good
Implementation Method 2
if a crack occurs in the inorganic material, the organic material in the first organic area can block the crack in the inorganic material, and thus prevent or slow the spread of the crack
