Display pixels of an electronic display may exhibit front-of-screen distortions when high spatial frequency image data is applied on the electronic display panel. The high spatial frequency may generate voltage ripple on a storage capacitor of pixel driving circuitry, causing mismatch between luminance of a first subpixel on an odd-numbered row and a corresponding subpixel on an even-numbered row. This odd-even row mismatch may be compensated via mismatch compensation circuitry. The mismatch compensation circuitry may include an odd subpixel compensation LUT and an even subpixel compensation LUT. The odd subpixel compensation LUT may output odd subpixel compensation values and the even subpixel compensation LUT may output even subpixel compensation values. The multiplexer may combine the odd subpixel compensation values and the even subpixel compensation values with input image data to generate compensated subpixel data, which may reduce or eliminate the odd-even row mismatch.
An electronic device, comprising:
Subpixel data mismatch compensation circuitry, comprising:
Tangible, non-transitory, computer-readable media comprising instructions that, when executed by one or more processors, cause the one or more processors to:
