Keywords: Electronic Paper (E-Paper), Invention, Printing, To build e-paper several different technologies exist, some using Innovation, Printing Media. plastic substrate and electronics so that the display is flexible. I. INTRODUCTION E-paper is also known as electronic paper and it is a technology designed to imitate the look and style of ordinary ink paper. E- paper reflects light just as ordinary paper does, unlike the usual flat-panel display that is lit with a backlight to illuminate pixels. It is capable of holding text and images indefinitely without drawing electricity, while allowing the image to be changed later. Electronic paper was first developed in the seventies by Xerox. In the nineties the principle of electronically loaded balls turning under influence of tension and therefore showing either a black or white side was improved upon by joseph Jacobson. In 1997, Jacobson founded the company E-link to develop the invention commercially (Endless Ideas BV, 2010). In the 1970s, Xerox PARC was a power house of innovation. Many aspect of the modern computer, namely the mouse, laser E-paper has the potential to be more comfortable to read than printer, GUI, a computer generated color graphics as well as a conventional display. This is due to the stable image, which does number of important computer languages were invented at not need to be refreshed constantly, the wider angle and the fact PARC, around that time .Yet another development, nearly lost that it reflects ambient light rather than emitting its own light.

Over the years, a number of methods for creating e-ink have been [1] Anderson,P., D.Nelson, P.Svenson, M.Chen, developed.

Each future-of-E-paper microcapsule is filled with a clear fluid containing positively charged white particles and negatively charged black particles. When a negative electric field is applied, the white particles move to the bottom of the capsule and are thus hidden from view. When a positive electric field is applied, the black particles migrate to the top and the white particles move to the bottom generating black text or a picture. The brightness and resolution of electrophoresis based E-ink is better than of bichromal-based E-ink, but both are monochromatic in nature. To create color, E- ink joined hands with the Japanese company Toppan printing which produces color filter. Advantages and Disadvantages of Electronic Paper: Electronic paper offers several advantages over printed paper. Advantages of electronic paper include low power usage(power is drawn when the display is updated) , flexibility, and better readability than most displays .Electronic-int can be printed in any surface , including walls ,billboards, product labels. The ink flexibility would also make it possible to develop roll-able displays for electronic devices.

  • Sustainable Alternatives to Industrial Printing Practices: a Case Study Analysis of Esquire Magazine and Electronic Paper Display
    Sustainable Alternatives to Industrial Printing Practices: A Case Study Analysis of Esquire Magazine and Electronic Paper Display Christopher Moore, Concordia University, Montreal, [email protected] Abstract In October 2008, Esquire magazine became the first commercial publisher to utilize electronic paper display technology (EPD) for mass production and distribution of printed ephemera. Initially developed at the MIT Media Lab in 1997, E Ink displays have been integrated into a variety of hardware devices, including the Amazon Kindle and Sony Reader. However, the Esquire cover represents a milestone achievement in the evolution of a more sustainable, paperless print solution due to the medium’s flexible nature, low power consumption, and limited circuitry requirements. 100,000 copies were sold on newsstands for the regular cover price of $5.99 USD, proving both the economic viability and flexible application of the technology, which is impervious to ambient lighting conditions and adaptable to multiple modalities. This paper outlines the key features and benefits of E Ink, as well as the critical challenges impeding widespread adoption of EPD. Keywords Sustainable design (primary keyword); design and society; eco-design; communication and information; case study/studies In response to political and consumer pressures, traditional print industries have increasingly adapted production methods to utilize more ecologically conscientious practices. Transitions to vegetable dyes, post-consumer fibres and dissolved air flotation de-inking processes have contributed to reduced environmental consequences from the paper and printing industries, but the overall output of ephemera has remained largely unchanged. The secondary carbon offset resulting from energy consumption and chemical disposal in the recycling and transportation of printed matter needs to be reconciled with advancements made in material technologies, and our cultural desire for tangible media.

  • Screening Environmental Life Cycle Assessment of Printed, Web Based and Tablet E-Paper Newspaper
    Title: Screening environmental life cycle assessment of printed, web based and tablet e-paper newspaper Second edition Authors: Åsa Moberg, Martin Johansson, Göran Finnveden and Alex Jonsson Reports from the KTH Centre for Sustainable Communications ISSN:1654-479X TRITA-SUS Report 2007:1 Stockholm, 2009 1 Preface This is a revised version of the report Screening environmental life cycle assessment of printed, web based and tablet e-paper newspaper (Moberg et al. 2007). The only revision made for this second edition is this Preface. We made the revision as we wanted to make clear that the calculations regarding web based newspapers in the report are based on a computer and screen with high energy use (in total 280 W, as listed e.g. in Table 4, p 23 in the report). This means that the web based newspaper energy use for reading reflects non-energy efficient equipment. Despite this the results of the assessment of the web based newspaper are valid. The lower energy use of computer and screen is evened out as energy for using internet is added (this was lacking in the report). Today’s PCs and especially laptops without additional screens have substantially less energy use while reading. Average PC and LCD screens on the market in 2005 in idle mode has an energy use corresponding to 110W and laptops are 32W (IVF 2007). To this should be added home equipment for accessing the internet; e.g. modem (around 9 W) and/or other user specific equipment. This equipment is often not turned off when not in use and the energy use during non-active time should also be taken into consideration.

Velayutham2*, Lindong Zhai3, Hyun Chan Kim3 and Jaehwan Kim3 1Nanotechnology and Catalysis Research Center (NanoCat), Institute of Postgraduate Studies, University of Malaya, 50603 Kuala Lumpur, Malaysia 2Low Dimensional Materials Research Center, Department of Physics, Faculty of Science, University of Malaya, 50603 Kuala Lumpur, Malaysia 3Department of Mechanical Engineering, Inha University, Incheon 22212, South Korea Received June 15, 2017; Accepted September 22, 2017 ABSTRACT Cellulose is a renewable biomass material and natural polymer which is abundantly available on Earth, and includes agricultural wastes, forestry residues, and woody materials. The excellent and smart characteristics of cellulose materials, such as lightweight, biocompatibility, biodegradability, high mechanical strength/stiffness and low thermal expansibility, have made cellulose a high- potential material for various industry applications. Cellulose has recently been discovered as a smart material in the electroactive polymers family which carries the name of cellulose-based electroactive paper (EAPap). The shear piezoelectricity in cellulose polymers is able to induce large displacement output, low actuation voltage, and low power consumption in the application of biomimetic sensors/actuators and electromechanical system. The present study provides an overview of biomass pretreatment from various lignocellulosic cellulose (LC) resources and nanocellulose production via TEMPO-mediated oxidation reaction, followed by the production of different types of EAPap versus its performance, and lastly the applications of EAPap in different areas and industries. Specifically, LC biomass consists mainly of cellulose having a small content of hemicelluloses and lignins which form a defensive inner structure against the degradation of plant cell wall.

  • Electrophoretic Displays (EPD)
    Electrophoretic displays (EPD) Display device is an output device for displaying information as visible or palpable such as Braille screen for blinds. Color or black and white images can be displayed by different devices that take electrical signals as an input and produce images on the screen. Among the display devices, Electronic Display or E-paper are a range of technologies on the screen that create an image similar to the effect of the ink on the paper. It is very similar to the paper so that it has used even the same color material in the printing industry. Electrophoretic Displays perform in active or passive modes. In this case, passive displays keep their image without the need to power consumption and the active displays use an electric current to display the image [1]. These display devices only reflect the ambient light like the ordinary papers and unlike the typical screens which have light. Many of these papers can show the fixed texts and images without the use of electricity indefinitely. Reading the electronic papers is easier than normal screens owing to the constantly changing the images, greater viewing angles and reflection of the ambient light instead of illumination of the screen. The writings of a good E-paper are not fade in the sunlight. The contrast ratio of the electronic papers that are presented up to the 2008 is similar to the newspaper, although this ratio is a little better in the newer electronic papers. Of course, the electronic paper should not be confused with the digital paper that is a screen to create handwritten digital documents using a digital pen.
