MEGAMORPH demonstrates its graphene-based display technology at Displayweek 2024

The EU-funded MEGAMORPH project, which started in 2022, demonstrated its graphene-based display technology at Displayweek 2024.

The idea behind the project is to use CVD graphene sheets (produced by Graphenea, a partner in the project) as the semi-transparent membranes in a Interferometric Modulator Display. These kinds of displays use mechanical micro-mirrors as pixels that modulate the ambient light without using power to generate light. IMOD displays are promising as they can offer very low power operation and high density displays.

Researchers grow GaN microLED arrays on a flexible graphene substrate

Researchers from Korea's Seoul National University and Sungkyunkwan University recently developed a method to grow GaN LED arrays on a flexible graphene layer. The so-called microdisk arrays exhibit excellent crystallinity with a uniform in-plane orientation and strong blue light emission.

The researchers grew the GaN microdisks on a graphene layer (grown on a sapphire substrate) covered with a micro-patterned SiO2 mask using metal–organic vapor-phase epitaxy. The microdisks were then processed into micro-LEDs and then successfully transferred onto bendable substrates.

MSI to unveil new QD-OLED gaming monitors with graphene heat dispersion technology

MSI, a leading manufacturer of gaming hardware, has announced it will be expanding its QD-OLED gaming monitor lineup. The new monitors will reportedly make use of graphene's thermal conductivity in its heat management technology. 

All models will be equipped with the latest generation of QD-OLED panels and will be available in both curved and flat models. Among other thing, the new monitors will enjoy a fan-less design, enhanced with graphene thermal tech for efficient and silent heat dispersion. This further extends the lifespan of these innovative QD-OLED panels.

Researchers develop graphene-based wearable touch panel for virtual-real handwriting interaction

Researchers from China's Qingdao University and Shenzhen University have developed a graphene-based proof-of-concept for a skin-friendly and wearable textile-based touch panel that converts a person's forearm into a keyboard or sketchpad. The three-layer, touch-responsive material translates what a user sketches or types into computer pictures.

Computer trackpads and electronic signature capture devices are not common in wearables. Researchers have proposed constructing flexible touch-responsive panels out of clear, electrically conductive hydrogels, but these materials are sticky, making writing on them difficult and uncomfortable for the skin. As a result, the research team sought to combine a comparable hydrogel into a comfortable fabric sleeve for drawing or playing computer games.

Graphene used to grow the world's smallest microLEDs and highest-density microLED arrays

Researchers from MIT, in collaboration with researchers from other Universities in the US and Korea, have used graphene (and hBN) to develop full-color vertically-stacked microLEDs  - that achieve the highest array density (5100 PPI) and the smallest size (4 µm) reported to date.

The researchers developed a 2D-materials based layer transfer (2DLT) technique - that involves growing the LEDs on 2D material-coated substrates, removing the LEDs, and then sttacking them. For the red LEDs, the researchers used graphene, coated on a GaAs wafer, while for the green and blue LEDs, they used hBN on sapphire wafers. The graphene red LEDs were transferred using remote epitaxy, while the hBN blue and green ones were removed using Van der Waals epitaxy.
