I recently purchased a digital thermometer probe for the kitchen, and it has a fascinating display that I would like to find out about.
When you turn the unit on, the display glows with an orange(ish) color, and is visible in the dark. The display consists of little four-pixel cubes that are activated to form the digits (graphics display?).
The interesting part is that, unlike an LED, when the display is in bright sunlight, the background looks blacker, and the digits are a pale gray or white - easily visible. The whole thing is running on a CR2032 lithium coin cell - so it must be low voltage.
Before I disassemble my new toy (with all the inherent dangers in that) to find a part number, does anyone have any idea what this interesting display type is called? I have a couple of projects that could benefit from this!
Thanks for any info,
Andy
