LCD vs LED Technology
LED is a new technology in TVs and Computer Monitors and distinctly different from LCD or TFT. LCD requires a backlight, LED does not. LCD uses silicon-based devices, LED uses organic plastic-based devices. LCD has low contrast, LED has very high contrast. LCD is now very old technology and will be replaced by the new organic LED quite quickly over next few years.
What is an OLED?
OLED (Organic Light Emitting Diodes) is a flat display technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. Because OLEDs produce (emit) light they do not require a backlight. This means that OLEDs can be made very thin and very power efficient when compared to LCD (which do require a white backlight).
OLEDs vs LCDs
OLEDs have the following advantages over today's flat-panel tech (LCD or plasma):
- Low power consumption - OLEDs are a far better choice for portable devices. It also makes OLEDs much more environmental friendly, and a candidate to be the white-light "bulb" of the future
- Faster refresh rate and better contrast.
- Greater brightness - The screens are brighter, and have a fuller viewing angle.
- Exciting displays - new types of displays, that we do not have today, like ultra-thin, flexible or transparent displays.
- Better durability - OLEDs are very durable and can operate in a broader temperature range.
- Lighter weight - the screen can be made very thin, and can even be 'printed' on flexible surfaces.
