Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional wiring and circuit elements are added to implement variable viewing angle technology, then the viewing angle selection capability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The data lines in the display panel are designed to serve dual functions: transmitting both image signals and mode selection voltages. By making the data lines universal, the patent eliminates the need for separate dedicated wiring for viewing angle selection, thereby reducing device complexity while maintaining the adaptability to select different viewing angles.
Solution Approach 2:
The patent combines the function of image signal transmission and viewing angle mode selection into a single data line system. The mode selection voltage is merged with the data signal transmission path, allowing both functions to be performed through the same wiring infrastructure, thus reducing the overall number of circuit elements required.
2Adaptability or versatility
If additional wiring and circuit elements are added to implement variable viewing angle technology, then the viewing angle selection capability is improved, but the manufacturing cost increases
Solution Approach 1:
By designing data lines to perform multiple functions (image signal transmission and mode selection voltage transmission), the patent reduces the total number of wiring lines required. This reduction in component count directly lowers manufacturing costs while preserving the ability to select different viewing angles.
Solution Approach 2:
The patent merges the mode selection control function with the existing data signal transmission system. This consolidation eliminates the need for separate dedicated control wiring, thereby simplifying the manufacturing process and reducing overall production costs.
3Adaptability or versatility
If viewing angle is controlled on a pixel basis, then the adaptability and viewing experience are improved, but the number of wiring lines and control circuits increase
Solution Approach 1:
The data lines are designed to universally handle both image data transmission and viewing angle mode selection for multiple pixels simultaneously. This multi-functional design allows pixel-level control without requiring individual dedicated wiring for each pixel's viewing angle selection.
Solution Approach 2:
The patent implements viewing angle control by dividing the display into pixel groups or regions that can be independently controlled. By segmenting the control approach and using the existing data line infrastructure, the system achieves pixel-level adaptability without proportionally increasing the wiring complexity.
