Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional display panels are used, then the display function is achieved, but photosensitive interaction capability is lost
Solution Approach 1:
The patent merges the display function and photosensitive sensing function into a single integrated panel structure. The photosensitive array is integrated with the display panel, allowing the same device to both display images and detect external light for interaction purposes, thereby achieving photosensitive interaction capability without adding separate independent components.
Solution Approach 2:
The display panel is designed to perform multiple functions: it serves as both a display device and a photosensitive sensor. The photosensitive units arranged in an array enable the panel to detect external light and convert it into electrical signals, making the panel universally functional for both visualization and interaction purposes.
2Adaptability or versatility
If photosensitive units are integrated into the display panel, then remote photosensitive interaction is enabled, but manufacturing complexity increases
Solution Approach 1:
The photosensitive array is segmented into multiple photosensitive units arranged in a grid pattern with specific row and column arrangements. Each photosensitive unit can independently detect light and generate electrical signals. This segmentation allows for modular manufacturing and simplifies the integration process by breaking down the complex photosensitive function into manageable discrete units.
3Measurement precision
If photosensitive array is added to enable light detection, then interaction precision is improved, but device structure becomes more complex
Solution Approach 1:
The photosensitive units are arranged in a two-dimensional array with specific row and column dimensions. This dimensional arrangement enables precise detection of light position by determining which specific photosensitive unit receives the light, converting spatial light information into electrical signals with high precision through the coordinated response of multiple units in the array.
