Abstract
A system may include an electronic display panel having multiple pixels for depicting image data and processing circuitry that may receive a first error value representative of a first difference between a first electrical signal measured at a first pixel of the multiple pixels and an expected electrical signal for the first pixel. The first electrical signal may be based on a test signal transmitted to the first pixel and the expected electrical signal may correspond to an expected response of the first pixel based on the test signal. The processing circuitry may filter the first error value to generate a first compensated error value and may filter the first error value based on the first compensated error value to generate a second compensated error value, where the second compensated error value may filter one or more effects of spatial crosstalk between one or more pixels near the first pixel.
