As a transitional product of the Optimus optical keyboard, the 3-button Mini optical keyboard naturally also uses OLED display technology with replaceable keycap display content. These three buttons all use 96x96 pixel OLED displays, which can show 262,000 colors and can display animated patterns at a speed of 5 frames per second. This keyboard will be available on the market on August 15th. Alas, it's just expensive～ For more details, you can visit his official website http://www.artlebedev.com/portfolio/optimus-mini/ "
