The debate over whether E Ink is really gentler on the eyes has been making the rounds since the dawn of e-book readers.
LCD is a much older concept for building displays.
E Ink is built to mimic the impression of ink on paper.
Here are the basic differences between E Ink and LCD:
|E-Ink (Electrophoretic ink)||LCD (Liquid Crystal Display)|
|Comes in grayscale (e-ink color scale is not used commercially in a big scale, yet)||Comes in a wide color scale|
|Used for e-book readers||Used for most smartphones, computers, tablets, and TVs|
|Does not have backlight||Has back-lit light|
|Little to no glare under sunlight and bright light||Highly reflective under sunlight or bright light|
|Excellent battery life||Drains battery much faster|
|Particularly used for reading e-books||Used mostly for browsing the Internet, playing games and watching movies|
While LCD screens are widely used, they are not the best choice if you want a device tailor-made for reading.
One driving reason for this is that they are bright. While this might makes the colors pop, it starts to hurt the eyes after prolonged use. Although many users complain of eye strain, dry eyes and headaches, no extensive scientific research has been done to prove that these are the direct effects of LCD display.
By contrast, e-ink devices have been adopted widely by the reading community. E-readers offers greater contrast without the glare of LCD displays and they are very easy on the eyes.
Latest e-book readers like the Kindle Paperwhite, Kindle Voyage, Nook GlowLight also come with a back-lit display. However, reading experience is generally still better on e-readers than on any LCD display.
If you are confused between these two displays, the best method is to think about your needs…
Go for an E Ink display if your primary focus is reading books and choose an LCD display for everything else media-related. That’s really the simplest way to look at it.
