Smart phone makers such as Apple and Samsung Electronics regard flexible display as the core technology of the next generation of smartphones; LG Display also decided to invest 2 trillion won (about 18 Billion US dollars) to establish small and medium size flexible OLED production line, the industry set off an investment boom flexible display. However, current touch panels are rigid and easy to break. Even if the flexible display can be bent, the matching touch panel can not be operated perfectly by touch if it can not be bent. Korean academia has developed a gel-type transparent touch panel technology that claims to have good ductility can also be applied to flexible displays, so that curly smart phones, wearable devices affixed to the skin of the commercial time Further ahead. According to a report by the Korea Daily, a research team led by Xuan Run-Run, a professor of materials engineering at Seoul National University in South Korea, developed a transparent and malleable touchscreen using hydrogel containing ions (Ion) Panel technology, the relevant content has been published in Science journals. The research team used polymers that were solid but liquid in appearance and resembled jelly or jelly-type gelatinous substances. After flattening the ion-containing gel, electrodes were attached to four corners to form a touch panel, The surface is driven by the surface capacitance. After the current generated by the touch is transmitted to the four corners, the amount of current is measured and converted into coordinates to calculate the position touched by the finger. In order to break through the physical limitations currently used for touch panel materials, such as electronic circuits, transistors and diodes, the research team chose to use ions instead of electrons as the conductor and become the core technology of the electrostatic touch panel. This touch panel made of technology such as hydrogel, ion and static electricity can be attached to the skin, inputting, drawing and playing handwriting on the computer after connecting with a computer, and the panel is extended by 10 times When, still can accurately identify the touch position. Xuanzheng Run said he is looking forward to using this research achievement to solve the problem that currently existing materials can not achieve. It is expected that more flexible materials that can be ionized should be developed in the future. GR (SHANDONG) NEW MATERIAL CO., LTD , https://www.grfilmcn.com
