As more people adopt eReaders, they’re likely to want to buy one with color ink. This technology is becoming more popular each year, and there are many different types of eReaders that can be bought. One type of eReader is the Kindle. This device has a color screen and uses an electronic book reader software called Kindle reading. Another type of eReader is the Nook. This device has a black and white screen and uses an electronic book reader software called Nook reading. There are also devices that use both color and black-and-white screens. These devices are called “multifunctional.” They can be used for reading, watching videos, or doing other tasks while you’re using them as a regular book reader. The best way to decide which type of eReader you want is to read some reviews of different types of eReaders before you buy one. You’ll also want to find out what kind of warranty the device comes with and how long it will last.
Digital book readers usually fall into one of two categories: ones with black-and-white screens with weeks of battery life, and models with regular LCD screens that aren’t much different from regular tablets. However, more eReaders with color E Ink screens are on the way.
E Ink, the company that designs the digital ink displays used in countless eReaders and other devices, has started mass production of the E Ink Gallery 3 display technology. The new tech supports a full-color gamut through cyan, magenta, yellow, and white particles. Black and white content refreshes at 350 milliseconds, “fast color mode’ (presumably with reduced colors) is 500 ms, standard color mode is 750-1000 ms, and the best color is 1500 ms. There’s also support for pen input, opening the door for a Kindle Scribe-type device with a color screen.
It’s not great that a full color refresh takes over a second, but E Ink still retains all of its advantages — less eye strain than a normal LCD or OLED screen, and much better power efficiency. E Ink only uses power when refreshing the display, unlike other display technologies, which require constant power to stay on.
