Apple patents display fix for visual banding near screen cutouts
Apple has filed a patent for a method to correct image data sent to screen pixels that are located near areas with electrical resistance issues, known as impedance distorting regions. The system adjusts the data based on the pixel's location to prevent uneven brightness or color stripes, or banding, from appearing on the screen.
In the filing’s own words
Electronic devices, displays, and methods are provided for compensating image data to account for banding artifacts. An electronic display may include an electronic display panel with lines and columns of display pixels and at least one impedance distorting region (IDR). Image data transmitted to pixel via lines that route around or through the IDR may be adjusted to compensate for parasitics that may be introduced by the IDR or routing around or through the IDR.
What exactly they claim (claim 1)
1. A device, comprising: processing circuitry; and local memory comprising instructions that, when executed by the processing circuitry, apply a banding artifact compensation to adjust image data for a pixel based on the pixel being disposed in a logical zone adjacent to an impedance distorting region at least in part by: receiving zone data corresponding to the logical zone; adjusting the image data based on the zone data; and transmitting the adjusted image data for presentation by the pixel.
