Organic light-emitting diodes or OLEDs are a series of organic thin layers sandwiched between two thin-layer conductive electrodes. When an electrical current is applied, a bright light is emitted.
OLED displays are thin and efficient, they provide the best image quality ever they can also be made transparent, flexible, foldable, and even rollable and stretchable in the future. OLEDs represent the future of display technology.OLEDs enable new designs and these devices emit healthier light compared to CFLs and LED lighting devices.OLEDs are very efficient and do not contain any bad metals. OLEDs are used today in mobile phones, digital cameras, VR headsets, tablets, laptops, and TVs.
OLED vs LCD
An OLED display has the following advantages:
1. Improved image quality - better contrast, higher brightness, fuller viewing angle, a wider color range, and much faster refresh rates.
2. Lower power consumption.
3. Simpler design that enables ultra-thin, flexible, foldable, and transparent displays
4. Better durability - OLEDs are very durable and can operate in a broader temperature range
OLED disadvantages
First of all, it costs more to produce an OLED than it does to produce an LCD - although this should hopefully change in the future, as OLEDs have the potential to be even cheaper than LCDs because of their simple design.
OLEDs have a limited lifetime (like any display, really), that was quite a problem a few years ago. But there has been constant progress, and today this is almost a non-issue. Today OLEDs last long enough to be used in mobile devices and TVs.
