Not long ago, E Ink corporation and Wacom also unveiled their first-ever color E-Ink Reader which will undergo mass production in Q3 2020. Later, Hisense worked with E Ink and released the first color E-Ink reading mobile phone at CES 2020. It seems like clolor E-Ink is going to be the popular technology topic in the coming years. So what’s color E-Ink and how does it actually work? Let’s find out in this post.
1. What is Color E-Ink and How does It Work?
What is color E-Ink?
Color E-Ink is a new popular color electronic paper display technology which produces color for each pixel that is displayed on the screen. This includes red, green, blue, black and white. It can also combine the colors allowing it to perform like a full color screen. At the same time, color E-Ink maintains the same ultra-low-power and paper-like readability as regular E-Ink display. Basically, color E-Ink is a standard E-Ink display with colour filters.
How does color E-Ink work?
With any reflective display we are using white light, which usually refers to natural light that contains all of the colors of the visible spectrum in roughly equal intensity. The challenge is to filter the desired color from the full spectrum. To do this, color e-ink display layers a transparent Color Filter Array over the black and white display. The Color Filter Array consists of one Red, Green, Blue, and White sub-pixel per full pixel on the black and white layer. Thus E-Ink display has the ability to combine various degrees of filtering to achieve most visible colors. Below picture explains the principle of how Triton’s color E-Ink display works. In short, color E-Ink is nothing but a E-ink display with three types of color filters slapped on top of it.
2. Benefits of Color E-Ink Display Technology
The main advantages of color E-Ink over E-Ink is that color E-Ink brings a lot of joy of reading colorful comics, magazines and graphic books. Here are some of important technical advantages offered by color E-Ink.
Colorful – displays thousands of colors and provides beautiful color images.
High resolution – describes an image displayed at high DPI (dots per inch) and contains a high amount of visual information.
Paper-like readability – reduces eyestrain since you are not staring at a LED screen.
Low power consumption – E-Ink display is non-volatile and does not draw power when the image does not change.
No glare – allows you to view text and pictures clearly in bright sunlight.
