Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of data lines is increased to achieve higher resolution, then the pixel density is improved, but signal interference between adjacent data lines increases
Solution Approach 1:
A shielding layer is introduced as an intermediary component between adjacent data lines to block electromagnetic interference. The shielding layer includes a metallic layer and a metallic oxide layer, positioned between the first data line and the second data line, acting as a mediator that prevents harmful signal crosstalk while allowing the high-resolution display structure to be maintained
Solution Approach 2:
The shielding layer is constructed using composite materials consisting of a metallic layer combined with a metallic oxide layer. This composite structure provides both electromagnetic shielding effectiveness and electrical insulation properties, resolving the contradiction by preventing signal interference between densely packed data lines while maintaining the high resolution display architecture
2Measurement precision
If the distance between data lines is reduced to increase pixel density, then the resolution is improved, but electrical crosstalk between data lines increases
Solution Approach 1:
The shielding layer serves as an intermediary barrier positioned between adjacent data lines, blocking the generation and propagation of electrical crosstalk. By placing this shielding structure between the first data line and the second data line, the patent prevents harmful electromagnetic coupling even when data lines are closely spaced for high pixel density
Solution Approach 2:
The harmful electrical crosstalk is extracted or removed from the system by introducing the shielding layer that actively blocks interference. The shielding layer with its metallic and metallic oxide components extracts the harmful electromagnetic fields between data lines, allowing high pixel density to be achieved without the detrimental effects of crosstalk
