OLED
Skip contentAlso known as: Organic Light Emitting Diode
OLED (Organic Light Emitting Diode) is a display technology. Unlike LCD displays which work by reflecting light, either ambient light or in its absence a backlight, OLED displays emit their own light and are legible in dark environments without an extra backlight, which helps reduce power consumption.
OLED displays are constructed of a set of thin organic films (the displays are generally less than 500 nm thick) placed between conductors; bright light is emitted when electric current flows through the conductors. This mode of operation is similar to that used in an LED (Light Emitting Diode) although the substrate is organic, hence the name.
- Advantages that OLED has over LCD include:
- Tougher and more durable
- Lighter
- Faster response, useful for video
- Brighter
- Wider viewing angle - up to 160 degrees
- Lower power requirement
Both passive and active OLED displays are available, with active displays having a better reponse rate and in some cases a more vivid image. Siemens is one company that has significantly invested in developing OLED technology.
