Vehicle Display Panel Current Sensing for Chromaticity Detection

The current detection process is segmented into two stages: a first detection period using a first sampling rate, and a second detection period using a second sampling rate. This segmentation allows the system to use higher sampling rates only when necessary (during initial calibration or when changes are detected), and lower sampling rates during normal operation, thereby reducing overall hardware complexity and power consumption while maintaining detection precision when needed.

The sampling rate is made dynamic rather than static. The system automatically adjusts the sampling rate based on the detection needs: using a first sampling rate during a first detection period and a second sampling rate during a second detection period. This dynamic adjustment allows the system to optimize between measurement precision and device complexity by using higher sampling rates only when actual detection is required and lower rates during stable operation.

The system implements periodic action by dividing the detection process into distinct periods with different sampling rates. During the first detection period, a first sampling rate is used; during the second detection period, a second sampling rate is used. This periodic switching allows the system to consume more energy only during necessary detection phases while conserving energy during stable operation periods, thus resolving the contradiction between detection precision and energy consumption.

The sampling rate is dynamically adjusted based on operational requirements. The system uses a higher first sampling rate when detection is needed and switches to a lower second sampling rate during stable periods. This dynamic adaptation ensures that energy consumption is optimized while maintaining the ability to detect minute changes in panel current when required.
