E Ink vs LCD Why E Ink eReader is Best

 

If you are a book lover considering ebook reader options we give you nine reasons for choosing an E Ink eReader such as the Kindle or Nook Simple Touch rather than an LCD eReader such as the iPad.

 

For some years now, there has been an ongoing debate on the question of whether E Ink and LCD eReaders are greener than physical books. eBook Reader Guide has succeeded in obtaining equivalent carbon dioxide emission data for the E Ink eReader that shows how much difference your eReader can make.

 

E-Ink readers providing the closest experience to printed paper. As the E-Ink works by reflecting ambient light, the display looks better in bright sunlight, unlike LCD displays that are backlit and can become swamped in the glare of bright ambient light.

 

E-Ink is the closest electronic substitute for paper, relying on ambient light to make text readable. LCD displays on the other hand emit light, and require the reader to stare at the light source. This can cause eye strain to some users, whereas E-Ink displays are found to be less stressful on your eyes.

 

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.

 

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.
