Graphic OLED Color Display 128x128 PDF Error ???

the PDF for the Color OLED display says in the center if the LCD, "Active Area 1.5’’

This cannot be, the whole screen is not even 1.5", its 36mm square, which is 1.41"

The real “Active Area” is 26.86 x 26.865 which is 1.05"

They’re doing marketing speak. 1.05" on a side, but 1.5" diagonal. Similar to how monitors have been spec’ed for years (minus that annoying bezel factor).

Ahhh… I See…
