Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a special shaped display panel is designed with a regular rectangular layout, then the wiring structure is simple, but the peripheral area width is large and border design is hindered
Solution Approach 1:
The display panel is divided into a display area and a peripheral area, with the peripheral area further segmented into functional regions. The signal lines are segmented into first signal lines (gate lines) and second signal lines (data lines), with dedicated multiplexers for each type, allowing independent optimization of wiring paths in different regions.
Solution Approach 2:
The patent transitions from a traditional two-dimensional rectangular wiring layout to a three-dimensional spatial arrangement by routing first signal lines and second signal lines through different paths and layers. The first multiplexer and second multiplexer are positioned at different locations, creating a multi-dimensional wiring architecture that reduces peripheral width.
2Area of stationary object
If the peripheral area width is reduced for narrow border design, then the screen occupation ratio increases, but the wiring structure becomes more complex
Solution Approach 1:
Multiple signal lines are merged into shared main lines through the multiplexer system. The first multiplexer combines multiple first signal lines into fewer main lines, and the second multiplexer combines multiple second signal lines into fewer main lines, reducing the total number of wiring paths required in the peripheral area.
Solution Approach 2:
The first multiplexer and second multiplexer act as intermediary devices between the signal lines and the main lines. These multiplexers enable efficient signal routing by selecting which signal lines connect to which main lines at different time periods, simplifying the overall wiring structure while maintaining functionality.
3Quantity of substance
If multiple signal lines are connected to the same main line simultaneously, then the wiring amount is reduced, but signal interference and timing control become problematic
Solution Approach 1:
The patent implements periodic switching of signal lines using the multiplexer system. Different signal lines are connected to the same main line at different time periods in a systematic sequence, ensuring that only one signal line is active on each main line at any given moment, thus preventing signal interference while minimizing wiring amount.
Solution Approach 2:
The wiring configuration is made dynamic through the use of switch elements in the multiplexers that can change connectivity states. The connection between signal lines and main lines is not fixed but dynamically adjusted based on timing signals, allowing the system to adaptively manage signal transmission and avoid interference.
