Today, there is an increasing trend among people to use compact and portable devices. There is a comfort that the lightweight devices give which was unknown to the previous generation. Technology grows a thousand times as fast as human beings do. And here, there is this new technology called FOLED that expands to Foldable Organic Light Emitting Diode, which is yet to enter the market. The research and development centres of many international companies like Samsung, Sony, Nokia, LG, etc, have made remarkable contributions to the development of this new technology.

An organic light emitting diode emits light due to a property called electroluminescence. Normally, these organic light emitting diodes are fabricated on glass. Instead, if these were fabricated on plastic, we get flexible displays.

The main advantage of this technology is that it enables the device to be bent or rolled while operating. Samsung has created a 0.27 millimetre thin screen with 800×480 pixels and 4.8 inches using organic light emitting diodes instead of glass. Another advantage of these devices are that they are shock resistant because of the use of plastic instead of glass.

A minor disadvantage occurs because of the use of a protective coating layer, which causes a loss of brilliance and colour of the display. The other disadvantages of this developing technology are, prolonged and continuous bending creates stress and wears out the screen easily and hence, there is a gradual decrease in the quality of image display. And also, making only the display flexible will not make the device flexible, when the battery, processer, RAM, and the other hardware are rigid. One thing that can be done is the flexible display can be connected to the rigid hardware.

Though this new technology has a few disadvantages, its advantages, which are portability and lightweight will definitely make it a success. R&D’s are also working on developing flexible hardware.
