Led display screen skin invent by Japan
According to Japanese media reports, a team of researchers from Tokyo university professor akira moriguchi ( electronic engineering ) has successfully developed a foldable, stretchable and ultra-thin led display screen for use in medical systems where patients can measure and display the wearer's heart rate data when they wear it.
The display screen is made of a flexible, breathable, rubber-like molding material with a maximum stretch length of 145 % of its original length and 384 small red-emitting LEDs mounted on it to control the display signal via nano-electrodes and retractable wiring.
The displayable portion of the screen is about 3.8 to 6.4 cm long and 5.8 to 9.6 cm wide, which is the size of a business card, allowing the patient to quickly learn about his or her current physical condition after being worn.
The screen is folded, and after 10,000 expansion experiments, the led is not damaged, and the short film can be displayed normally.
Because of the need for additional batteries, the big Japanese printing companies involved in the joint study plan to miniaturize and other improvements, hoping to be commercialized in about three years at a price of tens of thousands of yen.
