What's e-ink watch

E-Ink watch is a new kind watch that uses E-ink display. E-ink technology is generally well known for its use in electronic book readers such as the Kindle or Sony Reader and e-ink watches use this technology in their displays. It uses very little power to provide a high contrast display, twice the contrast of LCD displays in fact, the display can also be viewed from a much greater angle almost 180 degree, unlike similar displays such as LCD or LED. It's called E-ink because the high contrast legibility makes it similar to paper.

You may have come across a couple of terms, E-Ink, EPD and E-paper. What are the differences between E-ink watch and E-paper and EPD watch? Well, actually, they are the same thing! Both EPD and E-paper stands for Electronic Paper Display, and is the generic term for displays using the E-Ink technology. Featuring in innovative curved surface,high contrast,sunlight-readable,ultra-low power.E-ink displays are also thin and flexible and can be of virtually any size and shape which gives watch manufacturers the opportunity to come up with some unique designs.

E Ink, or EPD watches, are still only produced by a limited numbers of manufacturers.In 2005,Seiko was the first to demonstrate a commercial EPD watch back in 2005, and in 2010 announced the Future Now range, a technologically much-improved EInk watch with higher resolution and an all-round better display, with limited edition. After this, Phosphor,Pebble,GREEN VIEW launched their designed E-Ink,or E-Paper watch.

E-ink displays are aimed to look like printed pages, with a natural high contrast between black and white. It has exclusive ability to switch the displays, meaning you can either have black letters or numbers on a white background or white letters and numbers on a black background for your own preference.

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.
