Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple working prototypes are produced and calibrated to achieve desired display quality, then display quality is improved, but development time and cost increase
Solution Approach 1:
The patent creates a virtual emulation system that copies the optical characteristics and color gamut of physical display prototypes without actually building them. The emulation system uses software to simulate display performance, allowing multiple design iterations to be evaluated virtually, thereby eliminating the time-consuming process of producing and calibrating multiple physical prototypes while maintaining accurate assessment of display quality
Solution Approach 2:
The patent changes the parameters of display evaluation from physical prototypes to virtual emulations. By using color gamut data and optical characteristic measurements as input parameters, the system generates emulated display outputs that can be evaluated without physical hardware changes. This parameter-based approach allows rapid iteration through software configuration rather than physical manufacturing
2Manufacturing precision
If multiple working prototypes are produced and calibrated to achieve desired display quality, then display quality is improved, but development cost increases
Solution Approach 1:
The patent replaces expensive physical prototype manufacturing with a virtual emulation system. Instead of producing multiple physical displays with different color filters and optics, the system creates digital emulations that replicate the optical characteristics of various display designs. This eliminates material costs, manufacturing expenses, and calibration expenditures associated with multiple physical prototypes
Solution Approach 2:
The patent uses inexpensive software-based emulations instead of expensive physical prototypes. The emulation system can be configured to simulate various display designs at minimal cost, allowing numerous iteration cycles without the financial burden of manufacturing each physical prototype. The virtual models can be created, evaluated, and discarded instantly compared to the high cost and complexity of physical hardware iterations
3Measurement precision
If physical prototypes are built for evaluation, then accurate display evaluation is achieved, but the process becomes time-consuming
Solution Approach 1:
The patent creates accurate virtual copies of display optical characteristics using measured color gamut data and transfer functions. These emulations replicate the actual display performance with sufficient accuracy for evaluation purposes, enabling rapid assessment of multiple designs without the time required to build and measure physical prototypes. The emulation system maintains measurement precision by using rigorous optical modeling and characteristic reproduction

AI summary
In accordance with one embodiment, a method for emulating the color performance of a display system includes determining an expected first color gamut of the display system. Display data is converted into a format that emulates the first color gamut. The converted display data is displayed by a different display system having an expected second color gamut different than the expected first color gamut.
