OLED stands for Organic Light Emitting Diode a type of light-emitting diode (LED) technology in which an organic, carbon-based film is placed between two conductors and an electrical current is passed through, which causes it to emit light. OLED differs from LCD TVs, which require a backlight to create their brightness. OLED pixels are self-emissive and generate their own light.
OLEDs are used to create digital displays in devices such as television screens, monitors, and mobile phones.
There are two types of OLED technology: Passive-Matrix (PMOLED) and Active-Matrix (AMOLED).
Advantages of OLED?
- OLED technology has several advantages over other type of display technology like LCD and plasma technology.
- OLED sets are lighter and thinner than LCD due to the lack of a backlight.
- Can produce absolute black and high contrast ratio.
- Great picture quality because OLED pixels emit light directly and has viewing angles up to 90 degree.
- Fast response times of less than 0.01ms
Disadvantages of OLED?
- One of the main disadvantage of an OLED is that it generally quiet expensive.
- Organic materials can easily be damaged by water intrusion into the displays. Therefore an improved sealing process is necessary for OLED displays.
- Blue OLEDs have only a lifetime of around 5,000 hours.
