Why does text with minimal inter-character spacing in user interfaces typically exhibit reduced readability, especially on low-resolution displays?

💡 Explanation

Reduced inter-character spacing decreases feature contrast, because it reduces the visual distinctiveness between glyphs, especially on lower-resolution displays where individual pixels matter more; therefore, glyph shapes become harder to differentiate, rather than aliasing, reflow, or smoothing artifacts being the primary impediment.
