United Keys keyboard and keypad displays utilize Organic Light Emitting Diode (OLED) technology. OLEDs are widely used in TVs, computers and mobile phones, as well as general lighting purposes (i.e., in buildings).
A significant advantage of OLED technology is reduced power consumption. United Keys products are powered by a USB connection and do not require an auxiliary power supply.
The full keyboard is going to run you $259.99, while the OLED keypad is $199.99.
