Recently, Japan has developed a stretchable ultra-thin LED display screen, which is said to be stretchable by 145%. It is mainly used in medical systems. After wearing, the patient can control the display signal through the nano-electrode and the retractable wiring to display the wearer's heart rate. data.
According to reports, the research team of the University of Tokyo Professor Yoshihiro Takashi (Electronic Engineering) has successfully developed a pleated stretchable ultra-thin LED display screen, mainly used in medical systems, which can measure and display the wearer's after wearing. Heart rate data.
The display screen is made of a flexible, breathable rubber-like material with a maximum stretch length of up to 145% of its original length. It is equipped with 384 small red-emitting LEDs that are controlled by nano-electrodes and retractable wiring. signal.
The displayable part of the screen is about 3.8 to 6.4 cm long and 5.8 to 9.6 cm wide, which is equivalent to the size of a business card. The patient can quickly understand their current physical condition after wearing.
This kind of screen is pleated, and after 10,000 times of telescopic experiments in the test section, the LED is not damaged, and the short film can be displayed normally.
Because the display screen needs to be equipped with a battery, the Dainippon Printing Company, which is involved in the joint research, plans to improve on miniaturization. It is hoped that it will be commercialized at a price of tens of thousands of yen in three years.
