Display Crosstalk Suppression via Position-Dependent Pixel Correction

The patent applies local quality by making different parts of the image have different luminance characteristics based on their position. Specifically, the luminance correction amount is varied according to the vertical position on the screen, with greater correction applied to upper and lower regions where crosstalk is more severe, while maintaining original luminance in central regions. This localized adjustment suppresses crosstalk in affected areas without creating uniform black stripe patterns across the entire screen.

The patent changes the luminance parameter of pixels dynamically based on their vertical position on the screen. The luminance correction amount is calculated as a function of vertical position, creating a position-dependent luminance adjustment that suppresses crosstalk while avoiding the creation of visible black stripe patterns. This parameter change approach allows selective suppression of crosstalk without uniform image degradation.

The patent applies luminance correction selectively to specific vertical regions of the screen rather than uniformly to all pixels. The correction is concentrated in upper and lower regions where crosstalk occurs, while the central region maintains natural luminance characteristics. This localized approach preserves image naturalness in important viewing areas while suppressing crosstalk where it occurs.

The patent applies luminance correction to specific portions (upper and lower regions) rather than the entire image. By applying correction only where crosstalk is present and leaving central regions uncorrected, the method achieves sufficient crosstalk suppression without excessive action that would make the entire image appear unnatural.
