According to Japanese media reports, a research team led by Professor Takao Someya (Electronic Engineering) at the University of Tokyo has recently successfully developed a thin LED display that can be stretched and attached to the human body, and is striving to apply it to fashion and medical related fields.
The team also experimented with making a film that displays electrocardiogram curves in conjunction with sensors that are also attached to the body. “It can also be used to replace smartphones and tablets to display information,” Someya said.
The display is 1mm thick. Because of stretching, the part that can display the video is 3.8 to 6.4 centimeters long and 5.8 to 9.6 centimeters wide, the largest being equivalent to the size of a business card.
The rubber membrane stretched to an extremely thin level is equipped with 384 small LEDs that emit red light. Because of the wrinkle processing, the outdoor led video wall is not damaged after 10,000 stretching tests, and the video can be displayed normally.
The display requires an additional battery, and Dainippon Printing Co., Ltd., which is conducting joint research, plans to make improvements such as miniaturization, and hopes to commercialize it at a price of tens of thousands of yen in three years.
