研究目的
To address the color inconsistency in three primary-color LED light source modules by proposing a color compensation algorithm that personalizes RGB values based on feedback from three primary-color coordinates.
研究成果
The proposed color calibration algorithm effectively reduces chromatic aberration in multiple LED modules using the same set of RGB color duty cycle parameters, demonstrating significant improvement in color consistency across different modules.
研究不足
The study is limited to three primary-color LED light sources and may not account for all variations in LED manufacturing. The calibration process requires initial measurement of standard parameters, which may not be feasible in all applications.
1：Experimental Design and Method Selection:
The study involves designing a calibration algorithm for LED light sources to achieve color uniformity across multiple modules. The method includes obtaining standard three primary-color parameters, measuring the three primary-color parameters of each module, calculating the target color, and correcting the RGB values.
2：Sample Selection and Data Sources:
Three sets of lamp head modules are selected as experimental objects, with one set used as the standard module. Color coordinates and brightness are measured using a TES 136 Chroma meter.
3：List of Experimental Equipment and Materials:
MLX81106 and LRTB GVSG MULTILED are used as LED modules, KEA64 as the host, and a TES 136 Chroma meter for measuring color coordinates and brightness.
4：Experimental Procedures and Operational Workflow:
The calibration process involves four steps: obtaining standard parameters, measuring module parameters, calculating target color, and correcting RGB values.
5：Data Analysis Methods:
The effectiveness of the algorithm is verified by comparing the colorimetric parameters of LED modules before and after calibration.
