Exeter's GrapheExeter material to enable meter-sized flexible displays

Jul 31, 2016

Researchers at Exeter have devised a graphene composite (GraphExeter) that is highly conducting, and now they demonstrate the first prototype of the material in an electroluminescent device, showing its feasibility for luminescent textiles and flexible displays.

The high conductivity of GraphExeter can introduce many improvements to flexible displays. Large screens using existing materials fade to a darker region in the middle due to the sheet resistance. This places a practical limitation in the range of square centimetres on how large the screen can be. The extremely low sheet resistance of GraphExeter - less than 8Ω/□ compared with 1000Ω/□ for pristine single layer graphene and 850Ω/□ for the more commonly used PEDOT/PSS – means that screens several square metres in size are feasible.

Korean researchers demonstrate the world's first transparent OLED with graphene electrodes

Jun 24, 2016

Researchers from Korea's ETRI Institute developed the world's first transparent OLED prototype that uses a graphene transparent electrode. ETRI demonstrated the new display at the SID 2016 tradeshow.

The prototype display was 26x26 mm in size, with a resolution of 155x60 (121 PPI). The display was a monochrome (orange) display. In the display on show, the graphene-based electrodes were deposited on the backplane of the display.

Researchers create a foldable display on paper using a graphene-based ink

Jun 08, 2016

Researchers from Bilkent University in Turkey developed a new display prototype that is based on a graphene ink deposited on a regular paper. The paper display has high optical contrast and a fast response time. Such a paper-like display can be very flexible and foldable.

To create this display, the researchers used electro-modulation of the optical properties of the multilayer graphene via blocking the interband electronic transitions.

Korea-based researchers develop rollable OLED using graphene electrodes

Jun 03, 2016

Researchers from Korea's KAIST institute developed a rollable OLED device that uses graphene-based electrodes. The researchers say that the new OLED is much more durable when bent compared to current devices made with ITO electrodes.

The electrodes were made from a stack of materials - titanium oxdies, graphene and conductive polymers. The new OLEDs were also brighter than current devices, and with a higher color gamut. This was achieved by maximizing the resonance within the OLED.
