Whether a e-book reader is good or bad, its screen is the first thing to consider. What’s the difference between E-ink screen and Teclast X89 Kindow screen? Let’s talk about it.
What’s the E-ink screen?
Electronic Ink is a paperlike display used primarily in eBook readers such as Amazon’s Kindle. E Ink technology works by using tiny microcapsules that are suspended in liquid placed within a film-like layer. The microcapsules, which are about the same width as human hair, contain both positively charged white particles and negatively charged black particles. Applying a negative electrical field causes the white particles to come to the surface. Conversely, applying a positive electrical field causes the black particles to come to the surface.

E-ink screens are ideal for displaying black and white text. The big benefit to an E Ink screen is the way text appears on it. E Ink screens are advertised as “electronic paper” — they look more similar to paper than typical LCD screens do. However, E Ink screens can’t display colors (there are color E Ink screens, but they’re rare) and have a very low refresh rate. Another limit is that a shadow of an image may be visible after refreshing parts of the screen.
So what about the Teclast X89 Kindow screen?
The Teclast X89 Kindow is a new generation of portable e-book reader with dual OS. It is not only a ebook reader but also can be used as a tablet. You could watch online classes, browse PPT and videos. Obviously, E-ink screen cannot do such things. X89 Kindow is equipped with Samsung IPS HD eyes protection screen. It has 178° wide angle, 1440×1080 resolution, 4:3 aspect ratio and decent 240 PPI.
The brightness of the display can be adjusted. Whatever in a daytime or a darkness environment, the brightness of the screen could make your eyes feel comfortable to gaze at. It also has a good battery life. 3500mAh lithium Li-ion battery that offers video play time of up to 5 hours when charged to full capacity. This means that you can enjoy your favorite books, videos and music without charging the device every now and then. With Android and Windows 10 dual OS, all types of office documents can be checked and edited. Also, videos and games can be viewed and played.
What’s worth mentioning is that the Teclast X89 Kindow will cost less than $100. With so many features at an incredibly affordable price, the Teclast X89 Kindow really worth consideration.
Thanks for the review.
