After its introduction back in 2003, there has been a lot of improvements in developing the organic field effect transistors(OFET). OFETs were first developed to give out low cost large size display screens. But the latest reviews suggest improvements in light emitting organic field effect transistors (LE-OFET). LE-OFET combine functionalities of both, the OLEDs and the OFETs. These photoactive organic field effect transistors are said to possess the properties of amplifying weak signals and of receiving light too. Field effect carrier mobility of LE-OFETs has reached 20 cm^2/Vs which makes them good enough to be used in practical applications.
The review article also suggests that light emission efficiency and brightness of these transistors will soon improve. The next versions of the LE-OFETs are supposed to be compatible with the already existing electronic setups. LE-OFETs are also being used to develop transparent and flexible computer screens. With this said one can also think of their extensive use in smartphones too. These display units are said to offer faster response time and better energy efficiency. Above all these features, such display units inculcating LE-OFETs won’t require any backlight. This being said it is implied that the power consumption is bound to go down. They are also assumed to enable the development of optical communications and optoelectronic systems, since the switching rates of these transistors is quite good.
Japanese researchers also said that there are some issues in these components and a collaborative effort by organic chemists and device physicists is required to resolve these stumbling blocks. These developments would definitely open new frontiers for both electronic and photonic worlds with properties like flexibility, light weight, optical memory storage or high-density data storage. While it is speculated that such devices with all-plastic components and flexible nature will still take a decade to become ready for the users, you can only hope for its speedy development.
