|1.||Full Form||E-paper stands for Electronic paper||LCD stands for Liquid Crystal Display.|
|2.||Definition||E-paper or Electronic paper, a.k.a Electronic Ink Display (EID), is the representation of ink on paper with the use of technology.||Liquid Crystal Display (LCD) is a flat panel display technology which uses liquid crystals instead of cathode ray in its primary form of display operation.|
|3.||Thickness||E-paper is about 1 millimeter in thickness.||LCD is relatively thicker (approximately 7 millimeters)|
|4.||Screen Material||E-paper uses both glass and plastic screens.||Only glass screen is found in case of LCD.|
|5.||Readability in Sunlight||E-paper is easily readable in sunlight.||LCD makes it difficult to read in sunlight.|
|6.||Portability||It is easier to carry E-paper due to its light weight.||It is relatively difficult to carry LCD due to its heaviness which is because of the glass screen and power systems.|
|7.||Power Requirements||It is capable of holding text and images indefinitely without drawing electricity.||LCD needs power to hold images.|
|8.||View||E-paper has a viewing angle of 180 degrees, i.e. it can be viewed from anywhere if you are in front of it.||LCD can be best viewed only from the center front of the screen.||9.||Pixel Visibility||E-paper uses reflection of light for pixels to be visible||LCD uses back light illumination for pixel visibility.||10.||Commercial Examples||Amazon Kindle 2, Kindle DX, Touch and Kindle Paperwhite||Samsung, Sony and LG LCD televisions|
