Awesome Lcds

Typical LED and LCD screens on watches and clocks use seven segments to create Arabic numerals from 0 to 9. Pekero came up with a design concept for a 38-segment display that can show Chinese and Japanese numbers and some letters as well. At the end, they show how it might look on a watch, and you can check out an SVG file here.

LCD screens struggle with contrast because their crystals have to selectively block out a backlight. DIY Perks wanted to see if layering a second LCD panel could improve contrast. He combined parts from two identical displays, depolarized their screens, and upgraded their backlight. It’s a cool hack, but an OLED is still better.

LCDs and LEDs are everywhere, from smartphones to watches to TVs, to headlights. Musician and tech enthusiast Posy dives deep into one specific use of these technologies – displays which use segments to create numbers and letters. After a little history, he shows off some concepts for his own segmented designs.
