Each key is a stand-alone display that shows the function currently assigned to it.
Optimus's customizable layout allows convenient use of any language - Cyrillic, Ancient Greek, Georgian, Arabic, Quenya, hiragana, etc. as well as any other character set: notes, numerals, special symbols, HTML codes, math functions and so on to infinity.

Each key/screen is a 48 by 48 pixel, 10 frames per second, OLED screen.
In order to extend the service life of the displays and avoid using cables that may be vulnerable to wear, the screens embedded in the keytops are fixed - it’s only the transparent caps that are pressed.
Every button of the keyboard (or, more precisely, a module consisting of a moving cap, a microchip and a display) can be easily removed to clean or replace.
