E-paper technology is designed in such a way to mimic the appearance of ordinary paper. E-paper consists of thin electronic display, unlike ordinary display it reflects sunlight that gives the readers a much more legible text to read. Electrophoretic display: E-paper technology consists E-ink suspened between two transpare nt electrode layers. E-ink capsules are made of titanium oxide which are optically reflecting, when voltage is applied some particles move to viewing side of the paper thus causing the reflection of light it appears white If the particles move to the rear side of the display dark colored moves up front and hence it appears black,thus alternating the voltage a pixel is formed and hence the image. Further different types of colors can be obtained by placing suitable color filters color filters above the spheres Electrowetting: Electrowetting displays consists of water and oil interface, when no voltage is applied oil is above wate
