Gyricon
Gyricon is the forefather of electronic paper that Nick Sheridon in the 1970s at Xerox PARC in Palo Alto ( California developed). It has properties similar to paper : it is flexible and displays content that is clearly readable from a wide angle. The content can be changed several thousand times.
A gyricon sheet is made of a thin layer of transparent plastic that contains millions of tiny balls, similar to toner balls . Each ball is in an oil-filled shell, which allows it to rotate freely. The beads are two-colored (for example black and white) and have a bipolar static charge. When an electrical voltage is applied to the surface of the leaf , the balls align themselves so that the corresponding color points towards the surface. The image created in this way remains even when there is no longer any voltage.
In 2000, Xerox founded Gyricon LLC . The company was closed again at the end of 2005. Gyricon LLC had finally specialized in electronic displays (for example in shops). The main reason for the closure was because Gyricon LLC could not find a supplier who could sell the material for the back of the ads for less than $ 10 per square foot . It was therefore not economically feasible to offer the product at a price that was competitive on the market. However, Xerox continues to license the technology for the front.
