ePAPER

This is a new concept under rigorous research these days by major electronics companies. What this envisions is making use of molecule to make visual patterns.. Ever wondered what is happening with so many people with spectacles these days. This is a direct result of the current display technology - TV or computer screen let us read/see stuff by light from a artificial light source. Now this ePaper thing is the best alternate to this possible. What it means is that the display made by this is just like a paper in the way in which light comes to you. There is no illumination source. The light that falls on every object is what is reflected and lets you see the display, What this means is that the next generation will be chiefly spectacles free.
How it works. Well the display needs to display a message. Now the screen is divided into pixels as in any other display. This message that we want to display can be made by joining dots made by arrangements of black and white on the pixels. Once we get the pattern, the problem lies in how to make the pattern in that color. The answer is in some special chemical characteristics. The front side is colored black and the back is white. These chemical molecules form the pixel and chemicals are turned in a way that the effect is the display of the message. Now basic ebook readers on the technology are out on the market for a while. The next step is obviously color. This is also at a good stage. We can extend the technology to colors by using three chemicals displaying blue, red & green. Now the next step is display rate. The rate here at present is more suitable for reading texts and other static data as the refresh rate is not adequate. We need to get the refresh rate to enough so that video display is possible. That's the day you break your specs. On second thought you will still need them - just the next generation won't.
