Raster CRT Typography According to DEC
Interesting post. From my work on 1980s micros that used CRT TVs for display, the phosphor response described here seems to be a bit oversimplified.In my purely subjective experience, rise time seems to be shorter than fall time - pixels will usually be visibly blurred on the trailing (right) edge, but sharper on the leading (left) edge. Another thing I noticed is that a longer horizontal row of pixels will leave a longer decay on the trailing edge than a single pixel. For example, the Ts will usually have their horizontal line visibly stretched on the trailing edge, even when the vertical line seemed sharp.Of course, purpose-built terminals might have used different phosphors than cheap TVs of the time. It might also have to do with video amp bandwidth, or something else electrical.
