Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous detection and computation are performed to adjust for varying ambient light conditions, then display clarity is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary classification of ambient light conditions into discrete levels (first, second, third light conditions) and pre-determines corresponding background images. This preliminary action allows the device to avoid continuous computation by simply matching current conditions to predefined categories, significantly reducing power consumption while maintaining display clarity.
Solution Approach 2:
The patent applies parameter changes by transitioning from continuous light intensity adjustment to discrete light condition levels. The processing unit determines background images based on discrete light condition classifications rather than continuous computation, changing the operational parameter from analog to digital/discrete states, thereby reducing computational burden and power consumption.
2Adaptability or versatility
If continuous computation is performed to adjust display for ambient light variations, then display adaptability is improved, but computing power consumption increases
Solution Approach 1:
Multiple background images are pre-prepared for different light conditions (first, second, third light conditions) and stored in advance. The processing unit only needs to determine which pre-prepared image to use based on current light conditions, rather than computing adjustments in real-time. This preliminary preparation maintains display adaptability while minimizing computing power consumption during operation.
Solution Approach 2:
The system updates the background image periodically or event-driven (when light conditions change between predefined levels) rather than continuously. The processing unit determines a new background image only when ambient light conditions transition between discrete levels, reducing computing power consumption while maintaining display adaptability to varying light environments.
3Manufacturing precision
If multiple background images are stored and processed to match display content, then image quality is improved, but device complexity increases
Solution Approach 1:
Different background images with different resolutions are stored for different light conditions. The processing unit selects and applies appropriate background images based on current light conditions and display content requirements. This local quality approach ensures high image quality when needed while managing device complexity through selective application rather than universal high-resolution processing.
Solution Approach 2:
The system changes the resolution parameter of background images based on light conditions and display content. Lower resolution backgrounds may be used for certain conditions, reducing storage and processing requirements. This parameter change strategy improves image quality by using appropriate resolution levels rather than always using maximum resolution, thereby managing device complexity.

AI summary
A display method for displaying an image on a transparent display component of a display device includes receiving a display content, determining a background resolution of the image, selecting one of background images as a first background image based on the display content and the background resolution, performing image processing on the first background image to generate a second background image, adding the display content to the second background image to generate the image, and displaying the image on the transparent display component.
