We will look on OLED display technology but before that let’s discuss old display technology. In Earlier days, whether it was computer monitors or television sets those electronics product used to be heavier. Plus, they used to take a lot of space. Those displays were CRT based displays.
CRT is short for Cathode Ray Tube; is an analog display device. In which the image is created by the sending three electrons beam over millions of phosphor dots which ultimately lights them.
When talking about colour CRT displays; It consists of various stripes of red, green, and blue phosphor dots arranged in an alternate fashion. And when electrons are sent to those dots various colours gets produced by the screen.
This was a little overview, moving further to recent computer monitors and television sets. These electronics devices use a different technology now a days. Most of the electronic devices uses LCD or LED screens. And it is way much better CRT displays. Ultimately, this has resulted in the production of electronic devices with lightweight and thin display technology. However, OLED display is even much better than LED or LCD screen. But like every other technology OLED has both merits and demerits.

What is an OLED?
OLED is short for Organic Light-Emitting Diode. And in this LEDs are used where light is generated by organic molecules. Moreover, OLEDs are used to create best in class display panels till date without any doubt.
OLED display are popular these days because they generate vivid pictures. In addition to that, it supports high contrast, which means it can generate deeper blacks or you can say real blacks. Even more than LED or LCD screens. And this creates tremendous difference in picture quality.
You may think that why is it so? The answer is quite simple and straight-forward. First, we will have to know about what pixels are. So, pixels are nothing but the smallest unit in digital display. Talking about display screens; it consists of millions of pixels that work together with different patterns to form an image or video.
Particularly in Organic LEDs each pixels emits its own light whereas in LCD screens light comes from a backlighting unit. And due to this backlighting unit real blacks cannot be achieved in LCD screens. On the other hand, absence of backlighting unit facilitates the creation of real blacks in OLED displays.
Pros and Cons of OLED Display:
Pros:
- OLED displays are much better in comparison to LCD displays. Like OLED displays are much thinner than LCD displays.
- As the pixels of OLED screens are capable of emitting its own light as well as absence of backlighting unit makes Organic LEDs consume less power than LCDs.
- LCD displays refresh slowly and it impacts fast moving pictures whereas OLEDs responds up to 200 times faster.
- OLED produces life like colours and real blacks which is absent in LCD displays.
Cons:
- Due to less adoption of OLEDs; they are much costlier than LCD displays.
- Another point of demerit of OLED displays is that they don’t lasts long as comparison to LCDs.
What to expect in Future?
In the current time we already come across many of the foldable mobile devices that uses OLED screens in them. For example, foldable phones such as Samsung Galaxy Z Flip 4, Huawei Mate XS 2, etc. uses OLED screens in them.
In Future there are chances that we will be able to use rollable and foldable displays. Even electronic pages in a book are also possible with this kind of technology.
So, what do you think about this technology mention it in the comments below. And don’t forget to share this article with your friends and family. Thanks for Reading this article and I will see you in the next one.
