To minimize these type of spatial interference patterns, it is better to mix up the pattern
sequence similar to that shown in
pixels with sets of every other pixel. Depending on the display and patterns displayed, this
may create another type of apparent image distortion referred to as a walking pattern. One of
the matrix indices may need to be changed to count by 3 to eliminate this combination of
temporal and spatial distortion.
