When Privacy Display is activated, only the "narrow pixels" of the display are illuminated, simultaneously disabling the regular/wide pixels. These narrow pixels and the "Black Matrix" control the path of light, limiting the amount of light sent off-axis and narrowing the viewing angles. However, Maximum Privacy Display mode turns the 'wide'/regular pixels in the dark regions of the display back on, bringing most of the display towards a middle grey. This further obfuscates the displayed content at the expense of greatly diminished visual quality.
