Graphene flickers at 400Hz in 2500ppi displays

"Graphene is a versatile material with excellent mechanical, optical and electrical properties, and the combination of all of them enables the GIMOD technology," leading scientist Dr. Houri says.
Pixels in a GIMOD are electrically controlled membranes that modulate the white light from the environment. Dr. Houri says, "Measurements at TU Delft were sufficient to discover partially the potential of GIMOD pixels. We managed to characterize them up to 400 Hz, but we know they can reproduce the same color state at up to 2000 Hz." Humans cannot perceive flicker images beyond 500-1000Hz, but these displays beat the best commercial screens operating at 144Hz.

Dr. Cartamil-Bueno, the inventor and researcher that fabricated the graphene displays, shares his experience as entrepreneur bringing the GIMOD technology to the market. "We showcased GIMOD prototypes of 2500 pixels per inch (ppi) in the Mobile World Congress, and many players from the display industry reacted quite enthusiastically. While participating in several business contests in Germany, I have been preparing the team and securing capital. In few weeks, we will launch the startup to commercialize GIMOD components, aiming to tackle the VR market because that is where GIMOD outperforms every other technology."

The graphene pixels that the researchers presented are 5µm in size, in contrast to those in the Apple iPhone X (55µm), Samsung Galaxy S9 (44µm), and Sony Xperia XZ Premium (31µm). "Our GIMOD prototypes would have a resolution of more than 12K if we make them the size of a smartphone display," says Dr. Cartamil-Bueno.

I love graphene,it has so many great uses,they just need
to learn how to mass prudce it for manufacturing things.

First time I remember seeing Graphene was on Tommorrows World about 25 years ago maybe more and even then they said that this was the future of all screen technology, guess it's not as easy as they thought to manufacture.

Think it's more that it took all that time to develop the tools to scale down the process and massproduce it.
Hope it comes on the market quick, this is perfect for VR and FPV goggles.  Smile
