DeMura Table Compression via Fragmented Data Fetching

The DeMura table is divided into multiple fragments, each containing compensation data for a specific region of the display panel. Only the necessary fragments are fetched and processed at any given time, rather than loading the entire large-scale DeMura table into memory simultaneously. This segmentation allows high-resolution compensation while managing storage and memory requirements efficiently.

Different regions of the display panel have different compensation requirements. The patent fetches and processes only the local fragment of the DeMura table that corresponds to the current processing region, applying compensation data specifically tailored to that local area. This approach maintains high display quality while minimizing the amount of data that needs to be stored and processed at once.

The patent segments the DeMura table into multiple smaller fragments and stores them in a compressed format. Instead of requiring full storage capacity for the entire high-resolution DeMura table, the system only needs to store and process one fragment at a time during runtime. This significantly reduces the required storage capacity and associated costs while still supporting high-resolution display panels.

The system fetches DeMura table fragments periodically in a cyclic manner, processing one fragment at a time rather than loading all data simultaneously. This periodic fetching approach allows the use of smaller storage devices, as the system only needs to accommodate the current fragment being processed plus a small buffer, thereby reducing storage costs while maintaining the ability to handle large DeMura tables.
