A hybrid organic light emitting diode employing fluorescent family of blue light-emitting OLED and phosphorescent family of red and green light emitting OLED, each family being electrically isolated for driving current in to them independent of each other and thus prevent overloading the phosphorescent family when fluorescent family of OLED is driven at high current density. The electrical isolation built in to the device gives long life for the hybrid OLED and yields high brightness. The independent driving also yields additional advantage of varying the color temperature of white light from the device and thus enables the device to function as a variable color OLED lamp.
