How Works An OLED TV? The Easy Guide
If you’re an OLED fan but you don’t know too much about them, you’re in the perfect place. Today it’s time to find out how works an OLED TV – the beginner’s guide.
You don’t always need to know the mechanism that lies behind what you see. That’s the case of furniture, clothes and maybe even some appliances.
But in this case, knowing some basic stuff about how works an OLED TV could actually help you choose the best one on the market. So don’t skip the following lines , as they can save you a few hundreds. 😉
How It Looks Inside
In order to understand the mechanism that OLEDS are based on, you have to know a bit about their structure. Don’t worry, there won’t be too much theory. 🙂
The difference between OLEDs and other TVs are 2-3 layers of organic conductor, which are actually made of carbon. These organic layers have a very unique feature – they can create light once they receive electricity.
There are also 2 electrodes, an anode and a cathode, that are important for the electricity supply of the organic layers. The anode is always transparent, while the cathode may or may not be so, depending on the type of OLED.
And the last thing I have to mention here is the presence of a substrate, which is also essential for the good working of the OLED. This substrate can be made of glass or transparent plastic, again depending on the type of OLED.
No Backlight Means No Extra Space
If you look inside regular LCD TVs (which are 90% of the ones we have at home) , you can notice that the biggest part of the width is taken by the backlight. You can see how that backlight looks like in the instructions manual.
As that backlight is essential for the picture building-up, it is a must in regular TVs. That despite being the part that takes the most space.
On the other hand, it’s absolutely useless in an OLED TV, as the pixels create the image themselves.
So that’s the reason why OLED TVs are so thin – they don’t need any light source inside; each pixel placed on the organic layer can transform the electricity into light alone. And those little lights put together form the image we see on the screen.
So no backlight means much smaller dimensions and a much modern aspect.
No Backlight Also Means Less Consumption
In case you didn’t know, the backlight of a TV is its biggest energy consumer of all components. If it doesn’t exist, this means your TV will consume less power and you will pay significantly less when it comes to electricity.
However, the modern features of OLED TVs kind of compensate the things, as they consume a bit more than in case of a regular LCD. But even so, at the end of the day, things are still in the favor of OLEDs when it comes to the total energy consumed.
So the fact that OLEDs have pixels as a light source can also come as a help, even a minor one.
Conclusions To Remember
OLED TVs’ working mechanism may not be the easiest to understand, but it’s definitely among the simplest ones in technology. And if you understood these basic things mentioned above, I think you pretty much understood these TVs’ way of working.
So let’s make a little recap:
- OLEDs’ particularity is the organic layers that create light once they receive electric current
- These layers contain pixels that transform that energy into light. This means that pixels can turn themselves off (resulting the darkest black), or on (leading to a very pure shade of white)
- The backlight or the external source of light is absolutely useless in OLEDS
- Therefore, their dimensions (especially width) are much tinier than in any other TVs
- One last advantage is the reduced energy consumption, thanks to the same absent backlight
So that’s basically the mechanism OLED TVs use.
If you need more details, specialized sites would probably come more in handy than this one, but as long as you only need to know about OLEDs in large, what you read is enough.
