Internet of things breakthrough folding TV or reality

The internet technology has been broken into a "folding TV" or a reality-bending mobile phone, foldable TV, a window to display news ... These High-tech "fantasies" may soon become a reality. The author has learned from Fudan University that the core technology of IoT and intelligent goods-flexible organic thin film transistors (otfts) has been the major research progress. The researchers of Fudan University have first revealed the mechanism of influencing the stability of its performance, breaking through the key bottlenecks in the large-scale production of the technology. Relevant papers have been published in the international authoritative academic journal Nature-Communication Magazine. According to the introduction, in those of the chip itself performance requirements are not high, but can be a large area of flexible movement of the field, such as flat panel display and drive, medical imaging, intelligent packaging, Otfts presents a wide range of application prospects. However, the international academic community has previously opinions the cause and source of otfts performance instability. Fudan research team found that the otfts in different materials and carriers, the impact of the stability of the source is common, is the air of a large number of water molecules and oxygen molecules. In the atmospheric environment, these two kinds of molecules will be in direct contact with the otfts, resulting in water oxygen electrochemical reaction, blocking the normal operation of the device. Their interpretation has been widely agreed. Scientists have a vivid metaphor for this reaction mechanism. "The whole process is like throwing a lot of sponges in a flowing stream, when the sponge absorbs water, the stream is almost dry without water, and when the sponge is squeezed, the water flows out and the stream moves again." Shi Zhijun, associate professor of information engineering at Fudan University, said the creek describes Otfts devices, sponges refer to water molecules and oxygen molecules, absorption and extrusion are Shiga, reverse voltage processes, and water is current. "The current in the device constantly fluctuates, the logic operating state will be ' drift ', circuit work disturbance failure." "In view of the fact that there is no country or region in the world in the core hardware technology, especially otfts research and development applications have an absolute advantage, scientists believe that in this large-scale application of the biggest obstacle after cleaning up, as long as the sustained increase in attention and input, China will certainly in the relevant materials, Device and system integration to seize the opportunity.
