Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data conversion is performed to match display resolution with image data resolution, then proper display is achieved, but power consumption increases and dedicated circuits are required
Solution Approach 1:
The patent extracts the data conversion function from dedicated hardware circuits and relocates it to be performed by the host device's processor. This eliminates the need for separate conversion circuits in the display apparatus, reducing power consumption while maintaining display accuracy through software-based resolution matching.
2Reliability
If dedicated circuits are added for HDR processing and data conversion, then image quality is improved, but device complexity increases
Solution Approach 1:
The patent makes the host device's processor universal by enabling it to perform multiple functions including image processing, HDR processing, and data conversion. This eliminates the need for dedicated circuits in the display apparatus, reducing device complexity while maintaining image quality through software-based processing.
3Reliability
If resolution upconversion is performed, then proper display on high-resolution screens is achieved, but additional processing circuits are required
Solution Approach 1:
The patent extracts the resolution upconversion function from the display apparatus hardware and relocates it to the host device's processor. The display apparatus receives already-upconverted image data, eliminating the need for additional processing circuits while ensuring display compatibility through software-based resolution adjustment.
