The Advanced Color ePaper has been announced by E Ink, which the company tags as "Advanced" and as a "Breakthrough Technology" for color electrophoretic display (EPD) applications. There are numerous terms and acronyms accompanying the technology but they can be explained—and are worth reading about as they relate to the future of displays all around us. First, electrophoretic: E Ink is the creator of electrophoretic, or, electronic ink—the optical component of a film used in EPD.
Electronic ink is like paper, and is actually a straightforward fusion of chemistry, physics and electronics. The new entry offers a full color reflective display. Why is it a breakthrough? This is the first time ever, according to the company, where an EPD can produce full color at every pixel without the use of a color filter array (CFA).
The important feature about this reflective approach is that eliminating the need for a backlight significantly increases the battery life versus using a traditional LCD. In an E Ink display, no backlight is used; rather, ambient light from the environment is reflected from the surface of the display back to your eyes.
Advanced Color ePaper achieves a full color gamut, including all eight primary colors, using only colored pigments.
The company has a market end use in mind for improved color ePaper, focusing on displays and signage. Specifically, the company is targeting attraction toward low-power color displays.
E Ink makes the digital paper used in most eReaders like the Amazon Kindle and B&N Nook Glowlight, but the company has also been branching out into areas like digital signage and even digital luggage tags in recent years.
The company defined the eReader market with its ePaper technology, enabling a new multi-billion market in less than 10 years, according to the company release.
