Could smart technology have hit a block in it's progression? Samsung was the first to announce a new type of technology that is flexible and even stretchy. There are a few kinks that need to be worked out before it's mass produced. However, technology has stretched its flexibility in order to be more adaptable in everyday life.
The device will require low power to operate since it will charge via sunlight and ambient room light. However, it will be so “tough” and only use wireless connection ports, such that you can leave it out over night in the rain. In fact, you’ll be able to wash it or drop it without damaging the thin, highly flexible casing and screen.
Currently, faster, color-saturated, high-power devices like a computer’s liquid-cystal display screen, an iPad or a cell phone require high power (and, consequently, a larger battery), in part, because they need a strong internal light source within the device (that “backlights” the screen) as well as color filters in order to display the pixels as color/moving images. The need for an internal light source within the device also means visibility is poor in bright sunlight.
Now he is seeking to mount your big-screen HDTV on a flexible metal-foil substrate that can be rolled up and stored in a tube when it is not being used. He believes soldiers and rescue workers will soon scout unfamiliar terrain with interactive electronic maps displayed on flexible displays mounted on their uniforms.
Metal foils offer several advantages over plastic, or polymer substrates, says Hatalis. Because metal can withstand much higher temperatures, it is easier to fabricate electronics, especially high-performance electronics, on metal foils than it is on plastics. Metal foils are compatible with most wet-chemistry processes, and their resistance to moisture makes them ideal for OLEDs.
flexible oled not so flawless technology Flexible OLEDs are constantly being improved and perfected, several disadvantages draw issues toward the OLED technology. Albeit latest production of OLED TV is said to last 65,000 hours, there is still doubt concerning the short lifespan of the three-colored phosphors and if further developments will find a solution in the following years. Large production costs are main issues and questions concerning high-tier manufacturers are surfacing if they can go into mass produce.
This method of printing LEDs also allows for much smaller screens -- even as small as a fingernail. Such a small screen could have uses in medical health-monitoring devices. But such devices, if they are to be placed on the body, need to be flexible. No worry there: to connect islands of LEDs, Huang and his colleagues use the same “pop-up” technology they previously developed to connect tiny islands of circuits used in stretchable electronics. The tiny wires enable electronic transfer while also allowing the device to bend and stretch.
The OLED has some plasma-like technology in it. You know what it means: higher contrast, disregarding the room’s lighting, no motion lag and blur, and perfect viewing angles up to 1700. OLED uses organic materials that can be packed in extremely thin plexiglass or plastic that serves as a protector for the sensitive materials inside. These organic and carbon-based compounds are much like the multicellular plasma cells, they are individually lit, which results in better, deeper blacks and higher contrast in bright colors.
In the world of light-emitting diode screens, viewers can’t have it both ways. Inorganic LED screens made of silicon are bright, efficient and last a long time, but they are expensive, heavy and difficult to make in small sizes. Organic LED screens are cheap and flexible, but they produce a lower-quality image and have a short lifespan.
Flexible, see-through video screens may be the “killer app” that finally puts graphene — the highly touted single-atom-thick form of carbon — into the commercial spotlight once and for all, Tour said. Combined with other flexible, transparent electronic components being developed at Rice and elsewhere, the breakthrough could lead to computers that wrap around the wrist and solar cells that wrap around just about anything.
A hybrid material that combines a fine aluminum mesh with a single-atom-thick layer of graphene outperforms materials common to current touch screens and solar cells. The transparent, flexible electrodes were developed in the lab of Rice University chemist James Tour.
