The first E-Paper is developed in 1974’s by Nicholas K Sheridon at Xerox’s Palo Alto Research Centre. E-Paper is also called Electronic Paper or Electronic ink Display. It is a display unit. E-Paper is flexible. E-paper have a wide viewing angle. A digital pen is also used to create handwritten document.
E-Paper is an electronic ink display unit. It reflect light like ordinary paper. It is capable of holding text and images. It is flexible while using plastic materials and electronics. It is more comfortable to read than conventional display. A wider viewing angle. It can read directly from sunlight without fading images.
Light weight and durable. Low power consumption.
It has two different parts. ◦ Front plane. ◦ Back plane. The front plane consist of E-ink. The back plane consist of electronic circuits. To form an E-ink electronic display the ink is printed onto a plastic film that is laminated to a layer of circuitry.
GYRICON The first Gyricon E-ink developed in 1974s by “Nick Sheridon” at Xerox. It based on a thin sheet of flexible plastic containing a layer of tiny plastic beads each encapsulated in oil and it rotate freely. Each hemisphere of a bead has different colour and different electric charge. Electric field is applied the beads are rotate, creat two-coloured pattern.
This method have some limitations. 1.Low brightness and resolution. 2.Lack of color. Other form of E-ink with improve propertys compared to Gyricon is Electrophorestic.
Electrophorestic Electrophorestic frontplane consist of millions of micro capsules. Each approximately 100 microns in dia. Each micro capsule is filled with a clear fluid containing positivaly charged white particle and black particle.
A negative electric field is applied the white particles move to the top,causing the area to appear as a white dot. When a positive electric field is applied the black particle migrate to the top and white particle move to bottom. The disadvantage of this technology is it take time for the particle to move from one side to another. Drawing a new text or image is too slow and creat a flicker.
Ultra-thin and flexible energy cell. Eliminates the cost of the battery,weight and volume of the battery holder. Can be made into almost any shape. Can be integrated on almost any surface.
Low cost and simple to produce, using printing process. Environmentally friendly, non-caustic, no possibility of explosion, burns, or overheating.
Electronic ink display Liquid Crystal Displays Wide viewing angle Best image only from one position Black on paper white Gray on gray Readable in sunlight Can be difficult to see Holds image without power drain Required power to hold images
Electronic ink display Liquid Crystal Displays Plastic or glass Glass only Light Weight Power supply and glass make LCDs relatively heavy Thin (~1 mm)Thick (~7 mm)
Paper-like Readability. Ultra-Low Power Consumption. Clarity. Reduced Eyestrain. Mobile Display Solution. Hypertext. Multimedia Information. Include Graphics. Inexpensive.
Electronic Book. Electronic Newspaper. Mobile display. Computer monitor.
The E-Paper is a Flexible display. It is easy to use. E-Paper can communicate Satellite or other computers easily. Hand Wand Detach Printer
Researches found that in just few years this technology can replace paper in many situations, leading us to think of a truly paperless world.
