Display ads against smeared displays.
Users see black.
Everyone who uses a smartphone or tablet knows the problem: in no time at all, prints from fingers, cheeks and ears collect on the stylish, shiny displays of our everyday companions.
But even laptop and computer screens are not immune to annoying signs of use, as demonstrated by numerous key outlines, dust particles or those colleagues who like to press the display glass with their index finger. And the worst: Cell phones with darkened screens or the laptop in sleep mode show the smeary streaks particularly clearly.
