If the topic is not eyewear, contact lens, curved smartphones, camera or some other gadget then it may be a combination of several accessories and devices that are connected to a main device. This is exactly the case for Google’s invention of its eBook Reader that sports a Dual E-Ink Displays and also a camera. This connectivity involves three components that work in consort with one another.
Let’s break down the connected parts and describe them as they are and how they fit into the bigger picture for there are many parts and accessories to be sure. The centre piece is the eBook which was designed for garnering top acceptance. It’s so versatile it can allow the connecting of a keyboard or even a mouse to activate other related applications that may be needed to boost performance.
Media output is meant to be consumed and for this, many types of sophisticated and sensitive electronic devices are invented. In our case electronic devices are developed for the singular purpose of reading electronic books or e-books as they are more popularly known. These dedicated book reading devices are electronic and can be referred to as e-readers.
Whenever e-book devices emerges, they are often accompanied by the presence and use of electronic ink more popularly known as e-ink which facilitates the display aspect of an e-book and an e-reader combination. This technology aids the portability, as well as the readability from reflected sunlight similar to standard paper. The other notable feature is that battery life is quiet long since the need for power use occurs only during refreshing of the page.
In effect there are two ink displays with this Google invention. The first electronic ink display controls the creation of images while the second ink display reflect light to create the desired image. A sensor is also suitably configured to provide an indicator that may be manipulated to face a first and second direction and allow a refresh module to activate a second electronic-ink display. The second display then refreshes the image display made by the second electronic-ink display when it reacts to the indicator.
In performing its role as the producer of dual displays, the e-ink technology may enlist the help of a different range of modern technologies like electronic paper tech (Gyricon) that also includes polyethylene spheres. As an added example, the displays may also be based on EWD technology (Electro-wetting) for controlling the water/oil interface by applying needed voltage. The interesting aspect is that without the voltage, a water repellent film would develop between the water and oil resulting in an insulating film that produces a coloured pixel.
Essentially the invention is based on 2 display modes. In the first instance, the first page of the e-book is put on display for the user (#720) to read while the computing device is open. As the reader focuses on the first display, the second display #730 may be made to display a second page of the 3-book as the reader is still perusing the first page.
When the reader has read the first display page, his movements may be determined by the camera which would show that the reader has shifted attention from the first display page #720 and diverted his reading to #730. The first display page can then be refreshed to become the third page of the e-book and so on.
