Nanotechnology based TV and display
Do you like this story?
TelevisionPresent day colour televisions have big TV cathode ray tubes (CRTs) and are largely replaced by flat panel liquid-crystal displays (LCDs) LCDs which are more energy efficient, cause less eyestrain, and more compact then Cathode-ray tubes. Motorola’s Microelectronic and Physical Sciences Labs has developed Nano-emissive Display (NED) technology which gives not only viable but also affordable. It is claimed that in a year or two, the general consumer might be able to afford a 60-inch or larger display. This is done by making nanotubes grow in straight lines, looking rather like bristles on a hairbrush, in a temperature-controlled chamber filled with a mixture of hydrogen, methane, and the proprietary catalyst. Nano is cheaper in that way due to a savings in the electronic components and costing relatively low. The NED TV could cost considerably less than $3,000.

Now LED technology is widely seen. They are the bright pin lights often used on electronics as power and status indicators or as backlights. Using nanotechnology, these ultra-bright little lights can now be integrated on a panel densely enough to act as a display. By putting them in, while controlling intensity any color can be created. Nano-based LED displays are the size of LCD displays but are even brighter than CRTs and allow for smooth, crisp animation. What nanotechnology adds is the ability to make them small enough to put them into color-controllable clusters and pack them densely enough to create an image that is smooth to the human eye.
