Curved screen-electric thin film flexible touch screen

Bendable screens With the growth of the mobile phone market, the screens, which are important components of smart phones, are developing in the direction of refinement and flexibility, and Chinese scientists have made international breakthroughs. The new material technology research team of Chongqing University of Arts and Sciences led by Professor Tu Mingjing, academician of the Chinese Academy of Engineering, has recently developed a silver nanowire touch screen 4-inch mobile phone prototype and 10-inch tablet computer, which is a conductive film flexible touch screen.

The width of this material is only one-thousandth of a strand of hair. In the future, it can even be used to make a mobile phone with a bracelet-type wearable device. In the future, the editor will no longer have to worry that the screen of the mobile phone is too large to fit in the pocket. It is understood that most of the touch screens of mobile phones currently on the market are made of indium tin oxide (ITO) materials. Indium is a kind of expensive rare element material, this kind of material is getting less and less, and the price is getting higher and higher. The alternative material, graphene, must be produced in a vacuum state, and the finished product size and efficiency are not high yet, and the cost is high. In addition, touch screens account for 30%-50% of the cost of the entire mobile phone panel. In the future, whoever masters this core key technology and reduces costs to ensure quality will occupy the 'right to speak' in the market price of smart phones.

China's technology can really catch up with the technology of the world's technological powers, let us wait quietly. This time, the silver nanowires can produce 10 square meters per minute, with greater speed and productivity. In terms of technical indicators, the width of the nano silver wire is only one thousandth of that of a human hair, and the length can be 15 microns. It is learned from the 2015 International Symposium on Optoelectronic Materials and Devices held in Chongqing College of Arts and Sciences that the school has developed a conductive film flexible touch screen using nano silver wires. Realize industrialization.

Currently, the technology of the new materials research and development team of Chongqing University of Arts and Science has reached the same level in the world. Warm reminder: Of course, the conductive film flexible touch screen is expected to be industrialized next year, but there are still many problems to be solved in the application of mobile phones. Let's look forward to it together.
