Graphene is a two-dimensional material composed of carbon atom sheets. It is one of the strongest, lightest and most flexible materials known and has the potential to revolutionize the industry from healthcare to electronics.
The new prototype is an active matrix electrophoretic display similar to that used in today’s e-readers, except that it is made of flexible plastic instead of glass. In contrast to conventional displays, the pixel electronics or backplane of the display includes a solution-treated graphene electrode that replaces the metal electrode layer sputtered in conventional devices, providing product and process advantages.
Graphene is more flexible than conventional ceramic substitutes such as indium tin oxide (ITO) and more transparent than metal films. The ultra-flexible graphene layer enables a wide range of products, including foldable electronics. Graphene can also be processed from solution, giving the inherent advantages of using more efficient printing and roll-to-roll manufacturing methods.
Using organic thin film transistor (OTFT) technology, a new backplane of 150 pixels per inch (150 ppi) is fabricated at low temperatures (less than 100 ° C). The graphene electrode is deposited from solution and subsequently patterned with micron-scale features to complete the backsheet.
For this prototype, the backplane is combined with electrophoretic imaging film to create an ultra-low power and durable display. Future demonstrations may combine liquid crystal (LCD) and organic light emitting diode (OLED) technologies to achieve full color and video capabilities. Lightweight and flexible active matrix backplanes are also available for sensors, and new digital medical imaging and gesture recognition applications are under development.
The potential of graphene is well known, but industrial process engineering is now required to transform graphene from the laboratory to industry. The most important thing about flexible display is to have a flexible transparent conductive film, and Chongqing Yuanshisheng Graphene Film Industry Co., Ltd. can produce graphene transparent conductive film on a large scale, and the various properties of the product are also good. Let us look forward to the flexible display slowly appearing in our lives.
