Previously, if you wanted to use an OLED display, you had to use a power adapter. The problem was that OLEDs required low voltage to light up, instead of the standard (in Europe) 230v system. Now, scientists at Philips have announced that they have been able to design an OLED system that doesn’t require a step down transformer in order to work. This means that a device that uses an OLED lighting system won’t require the additional hardware components to change the voltage from whatever comes out of the wall to the low voltage previously needed.
Of course, this development in lighting technology will take a while to come to market, but the future does look bright indeed.
