This schematic image shows the flexible silicon NAND flash memory produced by the simultaneous roll-transfer and interconnection process.

Continuous Roll-Processing Tech

Highly productive roll-processing is considered a core technology for accelerating the commercialization of wearable computers, but it has been a difficult challenge.

This picture shows an OLED with the composite structure of TiO2/graphene/conducting polymer electrode in operation. The OLED exhibits 40.8% of ultrahigh external quantum efficiency (EQE) and 160.3 lm/W of power efficiency. The device prepared on a plastic substrate shown in the right remains intact and operates well even after 1,000 bending cycles at a radius of curvature as small as 2.3 mm.

Graphene-Based Electrodes for OLEDs

The arrival of a thin and lightweight computer that even rolls up like a piece of paper will not be in the far distant future.
