Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If tiled display devices use multiple electronic modules to form large images, then the display area and application scope are extended, but the image uniformity deteriorates due to different properties of the electronic modules
Solution Approach 1:
The patent changes the electrical parameters (voltage or current) supplied to each electronic module based on detected signal characteristics. By adjusting these parameters, the output signals from modules with different properties are normalized, achieving uniform image display across the tiled display system.
Solution Approach 2:
The patent implements a feedback mechanism where sensing elements detect signals from electronic modules, and the detected information is used to adjust the driving parameters of those modules. This closed-loop control ensures that variations in module properties are compensated, maintaining image uniformity.
2Manufacturing precision
If additional IC chips are added to each electronic module for calibration, then the image uniformity is improved, but the device complexity and cost increase
Solution Approach 1:
The patent merges the sensing function with the existing display structure by placing sensing elements on the same substrate as the electronic modules. This integration eliminates the need for separate calibration circuits and additional IC chips, reducing device complexity while maintaining calibration capability.
Solution Approach 2:
The sensing elements serve multiple functions: they detect signals from electronic modules for calibration purposes, and can potentially serve other functions in the display system. This multi-functionality reduces the need for dedicated calibration components, simplifying the overall device structure.
3Device complexity
If sensing elements are integrated on the same substrate as electronic modules, then the cost and complexity are reduced, but the manufacturing precision of signal detection may be affected
Solution Approach 1:
The patent segments the substrate into distinct regions for electronic modules and sensing elements, ensuring that the sensing elements are positioned to receive signals from specific modules without interference. This spatial segmentation maintains detection precision while allowing integration on the same substrate.
