Gadget Freak Case #250: DIY Flexible Display

Gadget Freak Case #250: DIY Flexible Display

Flexible displays are a hot topic, and my goal was to find a cheap and easy way to build one at home. Normally, flexible displays refer to Oled or E Ink, but I created a working prototype of a flexible display that can be built at home without special equipment.

The prototype shows a seven-digit display, but this guide can be easily modified to make a small dot-matrix display. The working prototype uses a sheet material printed with thermochromic liquid crystal ink. It changes color (bright blue) when heated above 27C. Nickel-chrome wire is used to heat the segments, and everything is controlled by an Arduino Mega board.
