LED stands for light-emitting diode. These are little solid-state devices that make light because of the movement of electrons through a semi-conductor. LEDs are relatively small compared to compact fluorescent and incandescent light bulbs, but they can get extremely bright. However, LEDs aren’t small enough to be used as the pixels of a television – they’re way too big for that. That’s why LEDs are only used as the backlight for LCD televisions. OLED stands for organic light-emitting diode. Very simply put, an OLED is made with organic compounds that light up when fed electricity. That may not seem like a huge difference when compared to LED, but OLEDs can be made to be extremely thin, small and remarkably flexible. On an OLED TV, each pixel lights itself up independently of the others. In this article we will Compared OLED and LED.
