Display Light Sensing Compensation Tables for Pixel-Level Uniformity

The patent applies preliminary action by pre-calculating compensation values for each light sensing module based on its position and characteristics before actual light sensing operations. A compensation table is generated in advance that stores correction data for all modules, which is then applied during runtime to correct non-uniformity issues. This preliminary compensation approach resolves the uniformity problem without affecting the high precision capability of pixel-level sensing.

The patent implements local quality by providing individualized compensation values for each light sensing module based on its specific position and performance characteristics. Instead of applying a global compensation factor, the system calculates and applies location-specific compensation data from the compensation table, ensuring that each module's unique non-uniformity characteristics are addressed individually while maintaining overall sensing precision.

The patent reduces real-time calculation complexity by performing all compensation value calculations in advance during a calibration phase. The compensation table is generated beforehand using reference light sensing data from each module, storing pre-computed correction values. During actual operation, the system simply retrieves and applies these pre-calculated values without performing complex real-time calculations, thus maintaining uniformity while reducing operational complexity.

The patent uses copying by creating a compensation table that replicates the non-uniformity characteristics of each light sensing module in a digital format. This compensation table serves as a reference copy that can be quickly queried and applied without重新calculating, effectively copying the correction data for rapid retrieval and application during light sensing operations.

The patent applies preliminary action by conducting comprehensive compensation table generation during an initial calibration phase using multiple reference light intensities and fused acquired values. This time-consuming data collection and processing is performed once in advance, creating a comprehensive compensation table that captures non-uniformity characteristics across different lighting conditions. During subsequent operations, this pre-generated table is directly applied without repeating the extensive data fusion process, thus achieving high accuracy while minimizing real-time processing time.

The patent uses partial action by performing the extensive data fusion and multi-intensity reference measurements only during the initial calibration phase, not during every light sensing operation. The excessive data collection (multiple reference intensities, repeated acquisitions) is done once to create a robust compensation table, which then suffices for multiple subsequent operations, balancing accuracy requirements with time efficiency.
