Scientists believe that soon graphene will be used commercially on the optoelectronics field, more especially in touch screens, LCDs and in organic lighting diodes (OLEDs). For any material to be used as an optoelectronic, it should transmit more than 90% of light and have electrical conductivity properties exceeding 1 x 106 Ω1m1. This means the product should have extremely low electrical resistance.  Graphene It is also the most conductive material so far known to man.  This makes graphene one of the most effective materials suitable for optoelectronic applications in the near future such as, smart screens, tablet LCD desktop computers and smart televisions.
