The new findings on printing the electronic devices can break through a new light on the technology and production of the delicate wiring and tiny components needed for flexible screens.This will help to produce Flat-panel computer displays by using novel inkjet printing equipment-demonstrated by Japanese scientists.

The researchers said “The technique is effective in printing the dots of one micron in diameter and it can be used to create intricate circuits.”The technique has been used for manufacturing tiny components and delicate wiring which are essential for flexible screens.“But the new inkjet head is able to produce 1,000 times smaller than standard printers”–Said the researchers.

“The present new findings demonstrates the possibility of inkjet technology in the making of electronic device applications,the technique provides better presentation of printed circuits,”-reported by the University of Tokyo in National Academy of Sciences.This new technique differs from traditional electronic devices.Traditionally, the inorganic materials are used to produce semiconductors.These inorganic materials do not have carbon,such as silicon.But in this new finding the polymers can be printed using the inkjet printers which are used to produce magazines.They are cheaper and quicker to produce and can be used in the devices of electronic paper.Moreover,plastic electronics are stronger than delicate silicon devices.

Researchers were working for building electronic devices for many decades.However, plastic cannot replace silicon in microchips of the High speed computer chips as the microchips require ultra-pure materials with precision in its design.

“The Printed electronics will be bigger in the size in comparison with silicon and they have relevance to photovoltaics,”Said Dr Peter Harrop to BBC News.The technique holds particular promise for so-called “organic” electronics known as plastic electronics.

These devices are produced from organic polymers which are used to make solar panels. This circuit’s would be cheaper than conventional silicon devices.These organic polymers are manufactured by some of the firms already.

UK firm Plastic Logic announced in 2007 about the plan to build a plant in Germany to produce flexible organic “control circuits” which can be used in”electronic paper”displays.
The new findings by University of Tokyo provide a new and more flexible approach.The researchers have created finer details to the print head that the inkjet can explode into one micron droplets.”This technique can be functional for high-purity electrical functional materials,”the researchers write.

Using silver nanoparticles ink, the researchers printed continuously two lines microns wide in a solvent. The researchers admit that the current prototype is slow for commercial work at this moment.
