In dark environments, such as a bedroom at night time, a reading light is needed to read E-Ink displays, as with printed paper. A backlit LCD eReader has an apparent advantage here as it does not require a reading light. However, studies have reported that the direct illumination from the LCD display can cause sleeplessness, whereas using an E-Ink eReader display or printed paper do not cause a “wake up” signal to be sent to the brain.

E-Ink devices are lighter than LCD devices due to a number of factors. First, this partly due to the energy efficiency of the E-Ink display resulting in smaller battery size. Secondly, as mention above E-Ink display is not suitable for displaying color or video (currently). Although this may appear to be drawback, it does have benefit that the device is designed specifically for reading and not distracted by other applications such as video, or game playing, with the consequences of increased processing requirement, increased storage capacity, a more complicated user interface, increased power consumption and increased device weight.

Due to the lower demands made by E-Ink displays on device resources compared with LCD (e.g. processing, data storage, display power consumption), the overall component cost of E-Ink eReaders is significantly lower compared with LCD eReaders. Therefore for cost conscious users who do not require extra functions that have little to do with book reading. Libraries and colleges, could minimize the cost of purchasing eReaders if they select the cheaper E-Ink based options, without reducing the readers’ experience. Continue reading …
E-Ink is much more energy efficient. Once a page is displayed on an E-Ink device, no further energy is required to maintain the display, unlike LCD displays. This energy saving results in two advantages: smaller battery size and longer battery life. Battery life of E-Ink devices is measured in weeks rather than hours for LCD based devices. A drawback related to this advantage is that current E-Ink displays are very poor at displaying video. Continue reading …
The E-Ink display is best suited to display the most common type of book: text only, non-interactive books. For this type of book, the main disadvantage of E-Ink display, the low refresh rate, becomes irrelevant. Furthermore text only books tend to be non-color, and this makes another disadvantage of E-Ink displays also irrelevant: poor contrast of color image on a color E-Ink display. Not only is the display readable outdoors, and less stressful on your eyes, but the resolution of all E-Ink readers is better than than most LCD displays (167 pixels per inch), and no worse than even the very best LCD displays available, although not a good quality printed text (300 pixels per inch).

Several studies have reported that fast reading and particularly skim reading is slower on backlit displays as compared with printed paper. As E-Ink is designed to simulate more closely printed paper it is expected that reading on E-Ink displays would be more productive than reading on LCD displays. Integrated reading tools, such are phrase search, dictionary, Wikipedia, highlighting and annotation help to close the gap between eReaders and printed paper. Continue reading …
E Ink eReaders are much lighter than LCD eReaders – typically weighing in at half for the same screen size device. The low weight combined with the small size of the E Ink eReader improves the handling of the eReader. So, if you are looking for an eReader that can be handled at least as conveniently as book, then E Ink eReaders provide the best option.
