In these pictures, you are looking at a terminal directory list. The right two thirds is covered by paper. The unmodified diffuser makes a low bound, and the printed card is a control. Some text was inverted to show how unreadable W-on-B is. Generally, you have to use black text on a while background, and be very strongly lit. Indoors, it was just barely legible under a desk lamp. Outdoors was much better, though in direct sunlight the laptop gets warm very fast. Black on white is necessary because every dark pixel casts a shadow. A black background means no light gets through to illuminate the white text. Images need to have their gamma cranked way up. Any theme needs to be pastel colored. Using the brightest whitest paper helps a little. Overall, this is a simple but barely useful modification.
