EBook reader buying advice: how are different E-Ink, OLED and LCD-IPS monitors. What are the respective advantages and disadvantages. Credit: Viacom-2011. The terms E-Ink, OLED and LCD-IPS fall often related to eBook readers and the representation. These terms refer to the device’s screen. Say, the technique is based on that of the monitor and thus the representation. What is the difference between E-Ink, OLED and TFT LCD-IPS? All today’s ‘real’ e-reader based on the E-ink technology. However, a future technology could be the so-called “OLED” technology.
The Taiwanese company of ASUS plans the first eBook reader on the market with “OLED” in 2010. TFT LCD-IPSBildschirme are the third technique. Apple’s new iPad relies on this technology. a / E-ink (“electronic paper”): an eye-friendly and fatigue-friendly read, provided comparable with reading a book in paper form. E-paper is not backlit like around a computer monitor, but it reflects light like ordinary paper.
Backlight is not eye friendly. Therefore leave with an E-ink screen Texts much more enjoyable read than on a LCD monitor. And above all you can read its digital books conveniently at the beach or in the garden even in the Sun with this technique. Sun don’t bother in contrast to background be illuminated displays. In addition, it is very energy efficient and a battery charge lasts for days, or rather weeks switched on (energy is required only for the page layout). Disadvantage of E-Ink: texts and images can be displayed in color, but only in shades of gray. And the screen layout is somewhat sluggish when compared to the usual LCD monitors. b / OLED screens (OLED stands for organic light emitting diode, German: organic light emitting diode): an alternative to E-Ink. Great advantage of OLED: it can be reflect colors. OLED screens require no backlighting as well as E-Ink and are thus not only very eye friendly, but also energy-efficient. OLED is a very bright and clear picture in full color. Asus is planning the first reader on the market with an OLED in 2010 Monitor. c / LCD-IPS: Apple’s new “media tablet” iPad built on top of an LCD-IPS screen. IPS allows the view from any angle without changing the color or contrast, unlike the “classic LCD”. Like all LCD monitors is also the LCD IPS with a backlight and is therefore not particularly eye-friendly. In addition, and that certainly is the biggest drawback can be such devices when the weather don’t go outside take, for example, to the beach and there read his books. The background lighting makes as it known also from the laptop, read out in sunny weather unfortunately impossible. It is, however, no problem with an E-ink or OLED display. Thus questionable whether you can count these types of readers under the category of eBook reader.
