Many people believe that OLEDs represent the future of display technology. In this blog, we look at what they are and some of the key advantages of OLEDs.
What are OLED displays?
OLEDs, or organic light emitting diodes, are a 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 are emissive displays which means that they do not require a backlight.
How do OLEDs compare to LCDs?
While OLEDs do not require a backlight as they emit light organically, LCD displays do require a white backlight. This means that OLED displays tend to be thinner than LCD displays as they do not require the extra layer for the backlight.
What are the advantages of OLEDs?
When comparing OLEDs to LCDs, they have a range of advantages which many believe makes them the superior option for certain functions. We outline some of the advantages of OLEDs below:
OLEDs have an improved image quality in comparison to LCDs, with higher brightness, better contrast and a wider colour range.
As well as having a superior image quality, OLEDs also have a much faster response time – one estimate suggests that they can be up to 1000 times faster than LCDs. This means that they have very high refresh frequencies.
Lower power consumption
While the image quality is superior, the display itself is also actually more efficient because it uses less power. This is because, as mentioned above, an OLED does not require backlighting and most of the power used on an LCD goes on backlighting.
Another advantage of OLEDs not needing a backlight is that the displays can be much thinner than LCDs. This allows for much sleeker designs when it comes to smartphones and television screens.
Lower future cost
While OLEDs are generally considered as more expensive to produce at the moment, it is thought that this will change in the future. The simple design of OLEDs means they could be more easily printed during mass production.
Potential for innovation
One of the best things about OLEDs is that they are lightweight and flexible, meaning the potential for technological innovation is far greater. If OLED displays can be created on flexible plastic substrates, this opens up the potential for flexible foldable and rollable displays, which could be used for wearable technology, foldable smartphones and more.
Are there any disadvantages to OLEDs?
The pros of OLEDs tend to outweigh the cons, which is why they are so frequently used in high-end smartphones and for other consumer electronics. However, this does not mean that they are perfect.
Some people have pointed out the lifespan of the organic materials used in OLEDs as a disadvantage. However, others argue that, given the rate consumers tend to replace their technology, this does not actually matter too much. The OLED material used to produce blue light also degrades at a much faster rate than the material used to produce other colours, which can affect the colour balance of the display.
Another potential disadvantage to OLED displays is that they don’t perform well in outdoor spaces, with poor readability in bright ambient light.
Those are just some of the advantages (as well as a few disadvantages) of OLED displays. If you are interested in acquiring OLEDs, you can take a look at our displays or get in touch to see if there is anything we can source for you.
