Unlike LCD, LED, or CRT display system, electronic paper technology attempts to achieve the clarity, contrast, and ease of viewing of normal paper on an electronic display.
The technology behind electronic paper is thirty years old; it was developed at Xerox PARC (Palo Alto Research Center). Nicholas K. Sheridon of Xerox PARC created a new display technology known as Gyricon (Greek for ‘rotating image’), which became the basis of the modern e-paper technology.
The ideal modern electronic paper should have high contrast like normal paper and low power consumption; it should be thin and light as well. The electronic paper display (EPD) is so light that it can be folded or curled, while still retaining the image. Also, the EPD should not lose the image even if power supply is not available. These concepts were used in the production of such products as Fabric PC from Fujitsu, which is a … Read the rest
