Introduction to AMOLED
AMOLED is an advanced form of OLED display technology that powers some of the most stunning screens in today’s smartphones. The name AMOLED stands for Active-Matrix Organic Light Emitting Diodes, and it tells you two key things about the display:
Active Matrix: This is the electronic system that works behind the scenes to bring your display to life in real-time, ensuring smooth and responsive performance.
OLED: Stands for Organic Light Emitting Diodes, which are millions of tiny, individual LEDs that light up to produce vivid colors and sharp details on your screen.
The result? A display that offers deeper blacks, more vibrant colors, and incredibly energy-efficient performance.
AMOLED vs OLED
You might be wondering, what is the difference between AMOLED and OLED? The answer is simple: AMOLED is the updated, advanced version of OLED. It features a thinner, smaller, and more flexible structure, making it more efficient and versatile.
Because of these improvements, AMOLED screens are thinner and better suited for higher refresh rates. They are perfect for devices like foldable smartphones and deliver improved video and picture quality.
Other advantages of AMOLED displays include:
— Low power consumption
— More color accuracy
— The ability to display true pitch black
— Ultra-slim design
— Reduced blue light emission, making it easier on the eyes
In short, AMOLED offers a better viewing experience while being more energy-efficient and visually stunning.
Dynamic AMOLED
Well, Samsung launched a new AMOLED display back in 2019, the Dynamic AMOLED display. Certain factors played a role in naming this new display as Dynamic AMOLED, such as HDR10+ certification for more brightness, color, and contrast. Worth mentioning that the dynamic AMOLED display is also certified by VDE Germany for 100% Mobile Colour Volume in the DCi-P3 colour range.
What is Dynamic AMOLED 2X?
Samsung did not just stop there, as the smartphone market is versatile. Samsung took their new AMOLED display and made it better, then named it the Dynamic AMOLED 2X. Well, there are some significant improvements seen in this display. Let’s dive into that.
DTM
This better AMOLED display has DTM (Dynamic Tone Mapping) that optimizes color and contrast to give a 100% accurate DCI-P3 color gamut. Therefore, you get to see cinema-grade videos and very sharp pictures without any distortions.
High refresh rate
The ‘2X’ part of the Dynamic AMOLED 2X display relates to the upgraded refresh rate from 60 Hz to an exceptional 120 Hz, ensuring super smooth scrolling and highly responsive movements – perfect for fast-paced gaming and multitasking. Screen flashing 120 times per second is super satisfying to look at.
Adaptive refresh rate
Samsung has taken display technology to the next level with Dynamic AMOLED 2X. One of its standout features is the dynamic refresh rate. This allows the display to adjust its refresh rate from 1 Hz to 120 Hz, depending on what you’re doing on the screen.
When you’re scrolling through content or watching something in motion, the display jumps to 120 Hz for smooth, ultra-responsive viewing. On the other hand, when you’re just reading or the screen is idle, it reduces the refresh rate to 1 Hz. Saves battery life.
Even better, most online videos run at 60 Hz, so when you’re watching one, the display automatically locks the refresh rate to 60 Hz, ensuring efficiency while delivering an excellent viewing experience.
It’s a clever way Samsung blends high performance with battery conservation — all while offering an exceptional display!
Adaptive brightness
In addition to all these features, Samsung has also made significant improvements to the brightness of its devices. The company has refined its adaptive brightness feature, allowing the Dynamic AMOLED 2X display to offer even more control. Now, your Samsung device automatically adjusts to the perfect brightness based on the surrounding lighting conditions, ensuring optimal viewing in any environment.
PWM dimming
AMOLED and OLED displays often struggle with color accuracy when the brightness drops below 90 nits. In such conditions, green may appear grayish, red can look faded, and blue might lose its vibrancy.
This happens because each LED on the screen controls both color and brightness. As the screen dims, the LEDs consume less power but still operate at a PWM rate of around 480 Hz. This results in a dull screen and inaccurate colors due to the lack of light generated by the LEDs.
To solve this, new AMOLED and OLED displays are using PWM dimming technology. While the LEDs still consume less power when dimmed, they now operate at a much higher PWM rate of 2,160 Hz. With this improvement, your eyes can no longer notice any issues. The color accuracy remains perfect, even when the brightness drops below 30 nits.
Working Procedure of the Dynamic AMOLED 2X Display
The working procedure for this high-end, futuristic display is a bit complicated. However, we are explaining the mechanism as simply as possible.
Structure
As mentioned earlier, OLED displays consist of millions of tiny LEDs arranged in a matrix. Each LED has three segments to represent the three primary colors: Red, Green, and Blue. Unlike LCDs, each OLED LED is independent and can be turned on or off individually.
Above the LEDs, there’s a thin glass layer that includes a touch sensor with air gaps in between, known as a digitizer. This digitizer enables touch functionality on the screen. Finally, the entire display is protected by another layer of protective glass, ensuring durability and a clear view.
Touch detection
The above-mentioned touch sensor layer has a film with electrodes. When you touch the screen, the electrodes of the film in that area touch the thin glass layer. This causes a voltage difference, which the display registers as a touch.
Displaying content
When displaying the time, an OLED display only turns on the mini-LEDs needed to show the clock, leaving all other mini-LEDs turned off. In contrast, the LCD displays require the entire screen to be lit, even the areas that are black.
With a Samsung Dynamic AMOLED 2X display, if you’re using a pitch-black wallpaper and dark mode, you’ll enjoy better battery life and more screen time, as fewer LEDs are lit.
Wrapping Up
The Samsung Dynamic AMOLED 2X display is currently the best display technology available on the market. Samsung has dedicated significant time and effort to perfecting this technology, ensuring it offers top-notch performance. All Samsung flagship devices feature the Dynamic AMOLED 2X, providing an unmatched viewing experience. While you may not notice the technology itself, the difference in display quality and efficiency is evident when compared to other screens.
