Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the pitch between pixels is reduced and the display panel size is enlarged, then the display resolution and coverage are improved, but the number of hardware components and signal transmission lines increases, leading to increased complexity and cost
Solution Approach 1:
The display panel is divided into multiple regions, with each region controlled by a separate timing controller. This segmentation allows the system to manage complex signal transmission by breaking it down into smaller, independent segments, reducing the overall complexity of signal routing across the entire large panel.
Solution Approach 2:
The patent introduces a new dimension of control by making the input/output port directions of timing controllers variable rather than fixed. This allows the system to adapt signal transmission paths dynamically, enabling more efficient routing and reducing the number of physical transmission lines needed across the enlarged display panel.
2Area of stationary object
If the number of signal transmission lines is increased, then the display panel size and resolution are improved, but wiring instability and increased complexity inside the display device occur
Solution Approach 1:
The timing controllers are designed with variable input/output port directions that can be dynamically configured based on the display panel size and signal transmission requirements. This dynamic adaptability allows the system to optimize signal paths and maintain wiring stability even as the display panel size increases, preventing the wiring complexity and instability issues that would otherwise arise.
3Ease of manufacture
If the directions of input/output ports in timing controllers are fixed, then the hardware design is simplified, but the difficulty of effectively coping with signal transmission issues increases
Solution Approach 1:
The timing controllers are designed with universal, multi-functional ports that can operate in different input/output directions. Each timing controller can function as either an input or output port depending on the configuration, allowing the same hardware design to adapt to various display panel sizes and signal transmission scenarios without requiring complex specialized designs for each case.
4Area of stationary object
If the display panel size is enlarged, then the display coverage is improved, but the cost and wiring complexity increase
Solution Approach 1:
The enlarged display panel is divided into multiple regions, each with its own timing controller. This segmentation reduces wiring complexity by localizing signal transmission within each region rather than requiring comprehensive wiring across the entire large panel, thereby managing the complexity that would otherwise result from enlarging the display area.
Solution Approach 2:
The variable port direction capability of timing controllers provides dynamic adaptability that reduces wiring complexity in enlarged displays. The system can configure signal paths optimally based on the specific layout and size of the display panel, avoiding the need for excessive wiring that would be required with fixed port configurations.
