E-Ink Watches - Watches Using The Latest EPD Technology As Used In E-Readers

Updated on December 1, 2012

Looking like no watch you've seen before E-ink watches are the latest ultra modern style of wristwatches. They use the latest development in electronic displays called E-ink or electronic paper display (EPD).

Previous developments in watch displays saw the replacement of watch hands; hour hand, minute hand and second hand with an electronic digital display. First to come was the LED watch display, followed closely by the LCD watch display. Now we have the E-ink or EPD watches, resulting in radical new watch designs as you can see.

E-ink displays are aimed to look like printed pages, with a natural high contrast between black and white. It is also possible to reverse the displays, so you can either have black letters or numbers on a white background or white letters and numbers on a black background, you can choose which you like best. Unlike other displays they are still easily read in direct sunlight.

You have most likely to have seen this type of display in e-readers, such as the Amazon Kindle reader perhaps.

Designers are making use of the fact that e-ink displays can be formed into large curved displays. Watch designs include a range of wristband style watches, where the display curves around the wrist.

So What Is E-Ink?

Electronic ink (E-ink) is a proprietary material which is processed into a film and integrated into electronic displays. The main components of electronic ink are millions of tiny microcapsules, roughly the diameter a human hair. In one form each microcapsule contains positively charged white particles and negatively charged black particles suspended in a clear fluid.

When a positive electric field is applied, the white particles move to the top of the microcapsule where they become visible to the user, making the surface appear white at that spot. Simultaneously an opposite electric field pulls the black particles to the bottom of the microcapsules and are hidden. If the charges are reversed, the black particles appear at the top of the capsule, which now makes the surface appear dark at that spot.

Now this all results in some futuristic looking watches that will surely be seen in science fiction films shortly. However unlike the LED prototype watch that appeared in the sci-fi cult film 2001: A Space Odyssey, the watch is in production first, see Gents E-ink watches now.
