What Is OLED? How Does It Wor?

Screen displays have been an important part of our lives for the good part of the past two decades.

We want the best quality possible when using a screen, whether on our mobile phones or on televisions.

New technologies, such as OLED, keep popping up for a better screening experience.

It is part of the LED family and has little tweaks for better screen vision. Let’s see what OLED is.


What Is OLED?

Organic Light-Emitting Diode or OLED technology is a LED technology that uses light produced by organic molecules inside the organic light-emitting diode.

OLED displays have thin organic films between the two conductors working inside the organic light-emitting diode.

The bright light is emitted when there is an electrical current in the display. This gives a contrasting color and better visual on the display screen.

It is not a complicated technology and design and has many different advantages over various other display technologies on screens.

OLEDs do not control every pixel; each pixel is individually controlled and emits its own light, which makes a quality visual when combined altogether, thanks to the various colors the pixel can emit by themselves.

Nowadays OLED can be seen in almost all 90 inch TV’s and 100 inch TV’s.

How Do OLEDs Work?

How OLEDs work could be a little bit complicated. However, OLEDs generally have a simple design that combines different materials and components on top of each other and creates organic light thanks to the organic material that emits the light within these components.

The main component of an OLED is the carbon-based organic material, also known as an OLED emitter. This material emits light when there is an electric current coming in.

In its layer, an emissive layer stays between a cathode that works to inject electrons and the anode that removes those electrons.

Even though some OLED technologies might have more layers for a more efficient and durable display, the main idea is the same and does not change.

Things To Consider Before Buying an OLED display?

Things To Consider Before Buying an OLED display

Here are a few things to consider before buying an OLED display:

1. Color Performance & Picture Quality

An OLED display is capable of producing true blacks, which makes them ideal when you are watching something in a darker room.

Also, OLEDs can reach a peak level of 1,000 nits in terms of brightness.

And also, OLED screens have a self-emissive panel which eliminates shadows and makes them ideal for viewing from any angle.

2. Response Time

Using a regular monitor for playing console games can affect your gaming experience because of slower response time.

But OLED screens have instantaneous pixel response time, which minimizes motion blur and is best for playing fast-paced games.

3. Gaming Performance

OLED screens support FreeSync technology which means you would face less lagging or ghosting issues while playing games. OLED screens are the best when it comes to gaming.

Which Devices Have OLED?

Which Devices Have OLED

OLEDs are not an entirely new technology; they have been in our lives for a considerable amount now.

Because the technology is reachable, it is widely used in many devices that have a screen like mobile phones or televisions.

Most mobile phone and television manufacturers create various versions of one product with different LED screens, including OLED screen displays.

This means that if you are looking to purchase an OLED screen television, you are most likely going to find this screen display technology in many television models and by different manufacturers.

Visual Differences Between OLED, QLED & LED

What Are Black Levels On an OLED TV?

Black level is the ability of an OLED screen to get truly black, whereas other displays, such as LCD, only get close to black.

Almost black is fine, but a true black screen gives you stronger contrast and better viewing quality.

So how do OLED TVs go truly black? In an LED display, the screen shines a little, even when the screen goes black.

But in an OLED display, each pixel creates light individually, and when the screen goes black, each pixel stops emitting light making the viewing experience more intense for you.

What is Infinite Contrast Ratio in an OLED TV?

Because an OLED screen can go truly black they have an infinite contrast ratio.

This means an OLED display has sharper and better image clarity which can be noticed in a dark room.

In a well-lit room, an OLED screen is bright and still does just fine. If you want to have the best viewing experience and have a dark room, then only we recommend you get an OLED TV.

How Can OLED Displays Enhance Viewing Angles?

How Can OLED Displays Enhance Viewing Angles

The pixels in an OLED display shines in all direction which eliminates light degradation, contrast, and color at extreme viewing angles.

This means no matter where you sit and view your tv from, the image that you will see will be the same and even from each angle.

The image on your tv will not look weird or have any type of shadow, which will make the viewing experience great for you.

What Is Better 4K or OLED?

So what is better, 4K or OLED? The answer is none. OLED is a type of display screen, and 4K is the resolution quality.

Because both are truly different from each other, they can’t be compared. On the contrary, both things together make a display better and contribute to better picture quality.


Burn-in is one major downside to buying an OLED TV. Burn-in is basically a black mark or shadow-like structure that can be seen on a certain part of the screen.

Burn-in occurs when an area on the screen is unable to produce the same amount of light as the rest of the screen.

Burn-ins can be caused when you watch a single channel for many hours each day. If you watch a variety of shows, then the problem of burn-in shouldn’t occur.

In the most common cases, what you will see is image retention, which goes away when you change the channel and watch something else.

The Verdict

In conclusion, OLED is an organic light-emitting diode screen display that works with organic molecules with thin organic films in the conductor.

It emits a bright light when an electric current is on the screen display. Also it is a fairly simple technology with a little bit of complex working design.

It combines the components you need for an OLED to work together. The main components are carbon-based organic material, cathode, and anode.

Most devices have OLED versions along with other LED technology versions.

How long does an OLED TV lasts?

The life span of an OLED TV is ideally more than 50,000 hours. This means if you watch 6 hours of tv every day, your tv will last for 22 years.

How much do OLED TVs cost?

OLED TVs range from $1000-$3000. The range is a bit higher as compared to other TVs because these are made from premium technology.

Is an OLED TV worth buying?

OLED TVs offer the best viewing angles, picture quality, infinite contrast ratio, and even very thin profiles on some models.

The only thing is OLEDs are not as bright as QLED or LCD TVs but are definitely worth the investment.
