Dynamic Brightness Compensation for Display Panels

The patent implements dynamic brightness compensation by selecting different compensation functions based on the current brightness level of the display panel. The system divides brightness into multiple ranges (first brightness range, second brightness range, third brightness range) and applies corresponding compensation functions (first compensation function, second compensation function, third compensation function) appropriately. This dynamic adaptation resolves the contradiction by making the compensation process neither overly simple nor excessively complex, but rather adaptively matched to actual display conditions.

The patent changes the parameters of the compensation function based on brightness level. Different compensation functions have different parameter sets optimized for specific brightness ranges. By adjusting which compensation function is active based on the current brightness value, the system achieves precise compensation across the full brightness spectrum while maintaining reasonable process complexity through systematic parameter management.

The patent applies local quality by using different compensation functions for different brightness ranges. The first compensation function is designed with parameters suitable for high-brightness conditions to avoid spot formation, while the second and third compensation functions use different parameters optimized for low-brightness conditions to effectively eliminate dark lines. This localized optimization of compensation characteristics resolves the contradiction by preventing harmful effects in each specific brightness context.

The system dynamically selects the appropriate compensation function based on the current brightness level. When brightness is high, the first compensation function is applied with lower compensation degree to prevent spots. When brightness is low, the second or third compensation functions are applied with higher compensation degree to eliminate dark lines. This dynamic adjustment prevents the generation of harmful artifacts across different operating conditions.

The patent implements dynamic selection of compensation functions based on brightness range. The system determines whether the current brightness value falls within the first brightness range, second brightness range, or third brightness range, and accordingly selects the first compensation function, second compensation function, or third compensation function. This dynamic approach ensures that high compensation is applied only when needed (low brightness) while maintaining stability at high brightness levels, resolving the contradiction between dark line elimination and transition stability.

The patent segments the brightness compensation process into multiple distinct stages corresponding to different brightness ranges. By dividing the overall brightness spectrum into three ranges and assigning specific compensation functions to each range, the system avoids applying inappropriate high compensation to high-brightness displays while ensuring adequate compensation for low-brightness displays. This segmentation prevents transition problems by ensuring each compensation function is applied only within its optimal brightness range.
