Researchers Developing Printed Electronics Using Gravure Press for Creating RFID Tags

“What we found was that when we put down the first layer associated with the liquid crystal manufacture, it destroyed the TFT layer,” he says. “You have to use aggressive solvents, which attack organic materials.”

Project researchers at the Imperial College London eventually found ways to modify the inks and other materials making up the TFT layer so as to resist the solvents. The result is a process for printing a TFT layer that is compatible with a liquid crystal display.
