Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If higher display resolution is used to achieve higher quality display, then image quality is improved, but power consumption of display interface increases
Solution Approach 1:
The patent divides display data into different portions and applies different compression configurations to different segments. Specifically, it separates data for different display ports (e.g., first display port and second display port) and processes each segment with appropriate compression settings, allowing high-resolution data to be transmitted efficiently while managing power consumption.
Solution Approach 2:
The patent applies different compression configurations to different portions of display data based on local requirements. Different display ports may receive data with different compression ratios or algorithms tailored to their specific needs, enabling optimal balance between image quality and power consumption for each local output.
2Use of energy by moving object
If data compression is applied to reduce power consumption, then power consumption is reduced, but image quality may deteriorate due to compression artifacts
Solution Approach 1:
The patent changes compression parameters dynamically based on display port and mode. Different compression ratios, algorithms, or configurations are applied to different display ports, allowing the system to adjust the balance between compression efficiency and image quality by modifying compression parameters rather than using a fixed approach.
3Manufacturing precision
If different compression configurations are used for different display ports, then image quality and buffer capacity are optimized, but device complexity increases
Solution Approach 1:
The patent manages complexity by segmenting the compression process into separate handling for different display ports. Each display port can have its own compression configuration managed independently, which simplifies the overall control logic compared to managing a single unified compression system for all ports.

AI summary
A data processing apparatus has a first compressor, a second compressor, a first output interface, and a second output interface. The first compressor performs compression upon a first portion of an input display data of a frame to generate a first compressed display data, wherein the compression performed upon the first portion of the input display data has a first compression configuration. The second compressor performs compression upon a second portion of the input display data of the frame to generate a second compressed display data, wherein the compression performed upon the second portion of the input display data has a second compression configuration. The first output interface transmits the first compressed display data over a first display port of a display interface. The second output interface transmits the second compressed display data over a second display port of the display inter face.
