In his brilliant documentary on the history of LCD technology, YouTuber Michiel de Boer (Posy) imagines a mirror with a built-in DSM LCD clock. To demonstrate that such displays aren’t required to have the straight-sided, segmented forms we’re accustomed to seeing in old calculators and watches, he uses a totally different style of letterform: the rounded JAF Domus with lowercase letters and oldstyle/text figures.
Speaking of conventional LCD number styles, De Boer is a multi-faceted sound and visual designer and has created many of his own segmented number designs.
