Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If multiple film layers are provided in the light-transmitting area to integrate functional components, then the screen-to-body ratio is improved, but the light transmittance uniformity across different wavelengths deteriorates
Solution Approach 1:
The patent applies local quality by providing different film layer configurations in different areas of the display panel. Specifically, the light-transmitting area has a reduced stack of film layers compared to the main display area, allowing higher and more uniform light transmittance for photosensitive components while maintaining the necessary structure in the display area for color filtration and other functions.
Solution Approach 2:
The patent segments the display panel into distinct functional areas: a main display area with complete film layers for color display, and a light-transmitting area with reduced film layers for optical component integration. This segmentation allows each area to be optimized independently for its specific function.
2Adaptability or versatility
If multiple film layers are provided in the light-transmitting area, then functional integration is improved, but the color fidelity deteriorates due to non-uniform light transmittance
Solution Approach 1:
The patent implements local quality by creating a light-transmitting area with a specialized film layer structure that differs from the main display area. This localized structural modification ensures high and uniform light transmittance for photosensitive components while preserving the color fidelity functions in the main display area through its complete film layer stack.
3Adaptability or versatility
If the light-transmitting area has a stack of several film layers, then component integration is improved, but the overall light transmittance decreases
Solution Approach 1:
The patent segments the film layer structure into two distinct regions: the main display area with a complete multi-layer stack for color display and component integration, and the light-transmitting area with a reduced film layer configuration. This segmentation enables the light-transmitting area to achieve high overall light transmittance while still providing necessary functional layers for component integration.
Solution Approach 2:
The patent applies local quality by providing a reduced film layer stack specifically in the light-transmitting area. This localized structural optimization allows the area to achieve high light transmittance for photosensitive components while maintaining sufficient functional layers for component integration, without compromising the overall display performance.
