- The University of Cambridge and other institutions developed the cracking-assisted transfer-printing method and presented it in Nature Electronics.
- The process first forms a thin quantum-dot layer, introduces controlled cracks and then transfers the patterned material onto a thin-film-transistor backplane.
- The researchers achieved electroluminescent pixels as small as 600 nanometers and uniform pixelization across areas extending up to 4 inches (10 cm).
- The team also fabricated a cadmium-free full-color active-matrix display with 341 pixels per inch and a blue active-matrix display with a flexible form factor; according to the authors, the method can improve luminance and operational lifetime over other quantum-dot patterning techniques.
"We create a cadmium-free full-color active-matrix display with a resolution of 341 pixels per inch, as well as a blue active-matrix display with a flexible form factor," wrote the authors. "Furthermore, the cracking-assisted transfer printing can improve electroluminescence performance—with higher maximum luminance and operational lifetime than other quantum dot patterning techniques—through precise nano-interface control and high quantum dot packing density."— Quoted from Jeong-Wan Jo, Yoonwoo Kim and colleagues in their Nature Electronics paper on cracking-assisted transfer printing for high-resolution quantum dot displays.
