Zone-Based Block Compensation for OLED Pixel Deterioration

The patent applies local quality by dividing the display area into multiple zones with different block sizes. Central region pixels use smaller blocks for higher precision compensation, while peripheral region pixels use larger blocks. This allows each region to receive appropriate compensation precision matched to its importance and deterioration characteristics, resolving the contradiction between compensation precision and processing complexity.

The patent reduces memory size by applying different block sizes to different display regions. Since peripheral regions use larger blocks (fewer blocks total) and central regions use smaller blocks (more blocks but higher precision needed), the overall memory requirement is optimized. This local differentiation strategy maintains high compensation precision where needed while minimizing total memory consumption.

The patent resolves this contradiction by assigning larger blocks to peripheral regions where lower precision is acceptable, and smaller blocks to central regions where high precision is critical for display quality. This spatially differentiated approach minimizes memory size while maintaining compensation precision in the most important display areas.

The patent reduces power consumption by processing different display regions at different effective resolutions. Peripheral regions use larger blocks requiring fewer processing operations, while central regions use smaller blocks for higher precision. This differential processing strategy maintains real-time compensation capability in critical areas while reducing overall computational load and power consumption.
