Zonal attenuation compensation

A computing device comprising:

• a display panel;
• and
• a display subsystem including:
• a graphics processing unit configured to provide image data to a display panel;
• a zonal attenuation module configured to combine a zonal attenuation mask with the image data to generate masked image data, the masked image data having a reduced brightness for portions of data corresponding to one or more regions on the display panel based on the zonal attenuation mask;
• and
• an inverse zonal attenuation module configured to apply an inverse zonal attenuation mask to the masked image data to reduce a brightness for additional portions of data corresponding to one or more additional regions on the display panel effective to offset a potential increased brightness in the one or more additional regions on the display panel, the reduction of brightness effective to offset the potential increased brightness resulting from the zonal attenuation mask diverting electric current from the one or more regions to the one or more additional regions.

A method comprising:

• receiving masked image data, the masked image data including image data combined with a zonal attenuation mask resulting in a reduced brightness for portions of data corresponding to one or more regions of a display panel based on the zonal attenuation mask;
• determining a brightness of additional portions of data corresponding to one or more additional regions of the display panel, the brightness including an increased brightness in the one or more additional regions of the display panel resulting from the zonal attenuation mask diverting electric current from the one or more regions to the one or more additional regions;
• selecting an inverse zonal attenuation mask configured to at least partially reduce the increased brightness in the one or more additional regions of the display panel;
• and
• combining the inverse zonal attenuation mask with the masked image data to generate adjusted image data.
