The main differences between OLED and LED include illumination method, picture quality, price and energy efficiency. The primary difference between OLED and LED is the method used to create the picture. OLED stands for organic light-emitting diode, and OLEDs use organic compounds to create the picture when electricity enters the diode. LED stands for light-emitting diode, and LEDs are similar to small bulbs that illuminate when electricity enters the bulb.
OLEDs offer superior technology, which generates a wider range of colors than LEDs. OLED technology illuminates each pixel independently and generates the deepest black of any diode in a flat-screen display. OLEDs are also curved and feature a larger viewing angle. The colors on LED displays become washed out and flat when viewing from different angles. This superior technology also allows OLED displays to provide a lighter and thinner product. The individual LEDs inside LED displays are heavier and space consuming, while individual OLEDs do not require backlight and use less power. As a result, OLED displays are more energy efficient. OLEDs also have better response times and are more flexible than LEDs.
Although OLEDs are currently more expensive than LED displays, experts project a significant price drop in the near future. Currently, OLED displays have the edge over LED displays.
