Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display panel size is increased for VR/AR applications, then the user experience is improved, but the user may feel dizzy due to inappropriate panel sizes
Solution Approach 1:
The patent optimizes the display panel dimensions and aspect ratio to match the human field of view in VR/AR applications. By carefully selecting the panel size and shape parameters, the system provides an appropriate display area that prevents user dizziness while maintaining immersive experience.
2Device complexity
If the data driver is located on the same side as the gate driver, then the device complexity is reduced, but the manufacturing cost increases
Solution Approach 1:
The patent divides the driver arrangement into two separate sides: the gate driver is located on one side of the display panel while the data driver is located on the opposite side. This segmentation allows for optimized manufacturing processes and reduced costs while maintaining manageable device complexity.
3Reliability
If auxiliary data lines are added to extend in the same direction as gate lines, then the connectivity is improved, but the device complexity increases
Solution Approach 1:
The auxiliary data lines serve multiple functions: they extend in the same direction as gate lines to improve connectivity across the display panel, and they are electrically connected to data lines through contact holes to enable signal transmission. This multi-functional design enhances connectivity without proportionally increasing complexity.
4Ease of manufacture
If data lines are connected to auxiliary data lines through contact holes, then the manufacturing cost is reduced, but the device complexity increases
Solution Approach 1:
Contact holes serve as intermediary structures that electrically connect the auxiliary data lines to the data lines. This intermediary connection method enables cost-effective manufacturing by using standard semiconductor fabrication techniques while maintaining reliable electrical connectivity between different line layers.
