Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If luminance compensation and color coordinate compensation are performed separately, then each compensation operation can be performed with simple measurement and processing, but the total time for generating image compensation data becomes relatively long
Solution Approach 1:
The patent combines luminance compensation and color coordinate compensation into a single concurrent measurement and processing operation. The image compensation device simultaneously measures both luminance values and color coordinate values from the display panel, and generates both luminance data and color coordinate data in parallel, thereby reducing the total time required for generating image compensation data while maintaining comprehensive compensation functionality.
Solution Approach 2:
The patent performs preliminary measurement of both luminance and color coordinate values simultaneously from the display panel before generating the compensation data. This preliminary concurrent measurement allows the system to prepare all necessary compensation parameters in advance, reducing the overall processing time and improving efficiency in generating the final image compensation data.
2Reliability
If only luminance compensation is performed, then the compensation process is simple and fast, but white balance becomes distorted due to efficiency disparity among red, green, and blue pixels
Solution Approach 1:
The patent merges luminance compensation and color coordinate compensation into a single integrated operation. By simultaneously measuring and processing both luminance values and color coordinate values, the system achieves accurate white balance correction while maintaining efficient compensation timing. The concurrent measurement and processing of both parameters ensures that color accuracy is improved without significant time penalty.
Solution Approach 2:
The patent maintains continuous and concurrent measurement and processing of both luminance and color coordinate data throughout the compensation operation. This continuous dual-parameter measurement ensures that color information is captured and processed without interruption or delay, maintaining accurate white balance while optimizing the compensation time through parallel processing of both luminance and color data.
