An organic light emitting diode (OLED), also organic electro luminescent device (OELD), is a light-emitting diode (LED) whose emissive electroluminescent layer is composed of a film of organic compounds. This layer of organic semiconductor material is formed between two electrodes, where at least one of the electrodes is transparent.
Such devices can be used in television screens, computer monitors, small, portable system screens such as cell phones and PDAs, watches, advertising, information and indication. OLEDs can also be used in light sources for general space illumination, and large-area light-emitting elements. Due to the younger stage of development, OLEDs typically emit less light per area than inorganic solid-state based LEDs which are usually designed for use as point-light sources.
In the context of displays, OLEDs have certain advantages over traditional liquid crystal displays (LCDs). OLED displays do not require a backlight to function. Thus, they can display deep black levels and can be thinner and lighter than an LCD panel. OLED displays also naturally achieve higher contrast ratio than LCD screens using cold cathode fluorescent lamp (CCFL) and newer LED backlights in conditions of low ambient light such as dark rooms.
So, it's not the same thing. You're welcome.
Though, for future reference:
