AMOLED Display

At the heart of the Galaxy S24 Ultra is its amazing AMOLED display. Now, you might be wondering, what in the world is AMOLED? Well, let’s me break it down for you in simple terms.

AMOLED stands for Active Matrix Organic Light Emitting Diode. Yeah, I know, that sounds super fancy, but don’t worry, we’ll explain it in a way that won’t make your brain hurt.

So, imagine the screen on your phone is like a sandwich. In the middle of this sandwich, there’s a super thin layer made of some special stuff called organic compounds. These compounds are sandwiched between two slices of something called conductors. Now, when you pass some electricity through these organic compounds, they start to glow, creating all those beautiful colors you see on your screen.

But here’s where it gets really cool. Unlike some other types of screens, AMOLED can control each tiny pixel individually. It’s like having a bunch of tiny light bulbs on your screen, and the phone can turn them on or off whenever it wants.

So, when you’re looking at something dark, the pixels representing that darkness can just turn off completely, giving you true, deep blacks. It’s like turning off the lights in a room to make it really dark.

And because of this, AMOLED screens have way better contrast ratios. That means the difference between the brightest brights and the darkest darks is really dramatic, making everything look more lifelike and immersive.

Plus, AMOLED screens are super energy-efficient, so they don’t suck up as much power as other types of screens. That means you don’t have to worry about your battery dying on you.

What sets AMOLED apart is its ability to individually light up pixels, allowing for true blacks by completely turning off pixels in dark areas of the screen. This results in superior contrast ratios and more immersive viewing experiences.

Gorilla Glass “Armour”

One of the coolest things about the display on the S24 Ultra is that it’s made with Gorilla Glass with Armor technology. Now, you might be thinking, “What’s the big deal about glass?” Well, let me tell you, this glass is pretty awesome.

So, first off, let’s talk about scratches. We all know how annoying it is when you accidentally scratch your phone screen, right? But with Gorilla Glass with Armor, you don’t have to worry as much. It’s like having a super tough shield protecting your screen from scratches and scrapes. You can toss your phone in your bag with your keys and not have to stress about it being scratched.

But wait, there’s more! This fancy glass also cuts down on glare by a whopping 75%. That means when you’re outside on a sunny day or in a really bright room, you can still see your screen perfectly. No more squinting and tilting your phone at weird angles just to see what’s going on. It’s like having your own personal shade for your phone.

So, whether you’re hiking in the mountains or just chilling in your backyard, you can enjoy crystal-clear visuals without any hassle.

LTPO Dynamic Refresh Rate

Another super cool thing about the display on the S24 Ultra is its LTPO (Low-Temperature Polycrystalline Oxide) technology. Now, I know that sounds like a mouthful, but stick with us, it’s actually really neat.

So, you know how when you’re using your phone, the screen refreshes really fast to make everything look smooth? Well, with LTPO, the S24 Ultra can change how fast it refreshes based on what you’re doing. It’s like having a speedometer in your car that automatically adjusts depending on how fast you’re driving.

So, let’s say you’re just checking your email or reading a text message. You don’t need the screen to refresh super fast for that, right? LTPO can dial it down to as low as 1Hz to save power. It’s like putting your phone into power-saving mode without sacrificing performance.

But then, let’s say you want everything to look super smooth. LTPO can crank up the refresh rate to as high as 120Hz, giving you that buttery-smooth experience you crave. It’s like upgrading from a clunky old bicycle to a sleek, high-speed sports car.

And the best part? LTPO does all of this automatically, so you don’t have to lift a finger.

PPI Density

The display on the S24 Ultra is seriously top-notch, thanks to its pixel density of 505 pixels per inch (PPI). Now, you might be wondering, what in the world is PPI? Well, let me break it down for you in simple terms.

PPI stands for pixels per inch, which basically means how many tiny dots of color are packed into every inch of your screen. And let me tell you, 505 PPI is pretty impressive. It’s like having a gazillion tiny little pixels crammed into your screen, all working together to create the most beautiful images you’ve ever seen.

So, why does PPI matter? Well, the higher the PPI, the sharper and more detailed everything looks on your screen. It’s like comparing a blurry photo to one that’s crystal clear and super sharp. With 505 PPI on the S24 Ultra, every tiny detail is rendered with precision.

So, whether you’re a photography enthusiast who loves zooming in on every little detail in your pictures or a book-reader who spends hours reading ebooks on your phone, the high PPI density on the S24 Ultra ensures that everything looks absolutely stunning.

History of AMOLED Displays

While AMOLED technology might not be brand new, it’s come a long way and evolved in some pretty amazing ways. Samsung started dabbling with AMOLED displays back in 2009 with their Samsung Omnia HD smartphone. It was like dipping their toes in the water to test it out.

Since then, AMOLED screens have become a must-have feature in Samsung’s top-of-the-line phones. It’s like they found the secret sauce and decided to pour it all over their devices.

And Samsung didn’t stop there. They’ve been tweaking and fine-tuning their AMOLED displays year after year, making them even better with each new release. It’s like they’re on a never-ending quest for perfection, constantly pushing the boundaries of what’s possible.

AMOLED may not be new, but it’s definitely still one of the best things to ever happen to smartphone screens.


Although, the only new technology in the S24 Ultra was its Gorilla Glass Armour which reduced glare by 75%. When other technologies from previous models meet it, it compunds fast!

So, Is it a worth it dealt to buy S24 Ultra if you are looking for a good screen? “Absolutely!” is the answer.
