OLED introduction and basic OLED information
What is an OLED?
OLED (Organic Light Emitting Diodes) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLEDs can be used to make displays and lighting. Because OLEDs emit light they do not require a backlight and so are thinner and more efficient than LCD displays(which do require a white backlight).
OLEDs are not just thin and efficient – they can also be made flexible (even rollable) and transparent.
OLED vs LCD
OLED displays have the following advantages over LCD displays:
- Lower power consumption
- 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
The future – flexible and transparent OLED displays
It turns out that because OLEDs are thin and simple – they can be used to create flexible and even transparent displays. This is pretty exciting as it opens up a whole world of possibilities:
- Curved OLED displays, placed on non-flat surfaces
- Wearable OLEDs
- Transparent OLEDs embedded in windows
- OLEDs in car windshields
- New designs for lamps
- And many more we cannot even imagine today…
