PI-Crystal Inc., an entrepreneurial spinoff from the University of Tokyo, said Dec. 8 that the LED panel it developed can bend freely like a curtain.
Working with display development firm Organo-Circuit Inc., PI-Crystal developed the technology to make high-precision transistors on a plane evenly from an organic semiconductor. They created a display panel by putting substrates, transistors and LED chips together on a resin sheet.
“We plan to unveil the LED panel as a fluttering display to show video footage or still images by next spring,” said Junichi Takeya, a material science professor at the university who serves as chief technology officer of the two companies.
The energy consumption and manufacturing costs of the newly developed LED screen are less than one-10th of those for existing displays.
The new LED display will weigh less than 1 kilogram per 1 square meter, according to PI-Crystal officials.
With growing demand for digital signage to be installed at event venues, airports, stations and elsewhere, PI-Crystal is looking to commercialize the bendable LED panel within two to three years.
