STRL is conducting research into stretchable displays that can be deformed into different shapes, allowing users to enjoy realistic and immersive content anytime and anywhere. This exhibit shows stretchable display and quantum-dot*1 LEDs*2 to produce vibrantly colored displays.
STRL has developed a stretchable LED*2 display using a flexible rubber-based substrate. Pixels are connected with stretchable wiring that can expand and contract freely, so it can be formed into different shapes, such as a dome, or wearable displays to show images on the skin.
Quantum-Dot Light-Emitting Diodes (QD-LEDs) with vibrant colors
Quantum dots are semiconductor crystals in particle form. They can be applied like ink and have potential as a light-emitting material with high color purity. By improving the material composition and device structure using a new quantum-dot material that does not contain toxic cadmium, STRL has developed vivid red, green, and blue QD-LEDs that will be effective in producing displays with a wide color gamut.
STRL will produce a prototype with ultra-high definition and high image quality by around 2025, to be put into practical use by 2030.
