AMOLED Display : Exploring Benefits And Drawbacks

* Introduction :
Have you ever wondered what makes your smartphone or tablet screen so bright and colorful? In front of you is an AMOLED screen - one of the most advanced and popular types of display technology available on the market today. But what exactly is an AMOLED screen and how does it work?

Why should you consider this when choosing your next device? In this article, we answer these questions by examining the pros and cons of AMOLED displays and how they compare to other displays. Read on to find out more!

AMOLED stands for "Active Matrix Organic Light Emitting Diode". The main difference between AMOLED and OLED is that an AMOLED display contains thin strips of thin-film transistors (TFTs) behind each pixel.

These transistors act as electricity superhighways, allowing current to flow rapidly across the screen. This gives AMOLED screens unique advantages over other display types. Let's take a closer look at the benefits:

* Faster Refresh Rate :
One of the main advantages of AMOLED displays is the higher refresh rate compared to other types of displays. The refresh rate indicates how fast the monitor can refresh the image on the screen in one second. A higher refresh rate ensures smoother and more realistic graphics, especially when playing games or watching movies.

AMOLED displays Excel because its pixels can be activated faster. For example, the Samsung Galaxy S21 Ultra has an AMOLED display with a 120Hz refresh rate, which allows the screen to refresh 120 times per second. This increases the smoothness and responsiveness of animations and transitions.

* Better Viewing Angles :
Another advantage of AMOLED screens is their excellent viewing angles compared to other types of screens. Viewing angle is the viewing of the screen from different angles and positions.

With AMOLED screens, each pixel emits more light, improving the overall visibility of the displayed image. This means you can enjoy content from any angle without sacrificing brightness or color accuracy.

Take the HP Specter x360 15t for example, which has an AMOLED display with a 178-degree viewing angle. This allows you to tilt or rotate the screen without sacrificing picture quality.

* Higher Contrast Ratio and Deeper Blacks :
AMOLED screens offer a higher contrast ratio and deeper blacks than other screen types. Contrast ratio refers to the difference between the lightest and darkest colors on your screen.

A higher contrast ratio provides more vivid colors and more details. With AMOLED screens, pixels can be completely turned off when displayed in black, creating a black color that adds contrast and depth to the image. This means you can enjoy content in a more realistic and immersive way.

For example, OnePlus 9 Pro is equipped with an AMOLED display with a contrast ratio of over 5 million to 1, capable of representing over 5 million shades of color and offering an exceptional visual experience.

* Lower Power Consumption and Battery Life :
AMOLED screens are characterized by excellent energy consumption, offering lower power consumption and longer battery life than other types of screens. Lower power consumption means less heat generation and less drain on the battery. Thanks to the longer battery life, you can use your device longer without having to charge it frequently.

This will increase the convenience and comfort of using the content. Take the Dell XPS 13 2-in-1, which features an AMOLED display and consumes just 1 watt. This results in battery savings of up to 20% compared to devices with other screen types.

* Higher Cost and Availability :
The disadvantage of AMOLED screens is the higher cost and limited availability compared to other types of screens. The manufacturing processes and materials required for AMOLED displays are more complex and sophisticated, reducing the number of manufacturers and suppliers who can produce them at scale and at affordable prices.

According to Statista, in 2020 only 17% of smartphones sold worldwide were equipped with AMOLED screens and 83% with LCD screens. That means you may have fewer options and higher prices when buying devices with an AMOLED screen.

* Risk of Screen Burn-in :
AMOLED screens are more prone to screen burn-in or screen degradation than other screen types. Screen burn is permanent discoloration or ghosting of the screen image caused by prolonged exposure to static or repetitive content.

However, degradation is the gradual loss of brightness or color accuracy over time as organic materials age. As a result, using an AMOLED display for long periods of time or at high brightness settings can result in degradation in quality and performance over time.

According to the Android Authority report, some users have reported screen burn-in issues on their Samsung Galaxy S8 and S9 devices after several months of use.

* Oversaturation or Inaccurate Color Reproduction :
In some cases, AMOLED screens can experience oversaturation or inaccurate color reproduction. Oversaturation means that on-screen colors are exaggerated or boosted, making them appear more vibrant but less natural.

Color inaccuracy is the deviation or distortion of colors on the screen, causing them to appear different from the source. These factors can prevent an AMOLED display from displaying content as intended or preferred, especially for professionals and enthusiasts who value color accuracy and fidelity.

* Brightness and Visibility in Bright Environment :
AMOLED screens may experience reduced brightness and visibility in direct sunlight or in brightly lit environments. Brightness refers to the amount of light emitted or reflected by the screen, while visibility refers to how you see the screen in different lighting conditions.

As a result, viewing and using AMOLED screens outdoors or in well-lit rooms can be more difficult, especially for people with sensitive eyes or those who need good legibility.

For example, the HP Specter x360 15t's AMOLED display has a brightness of just 247 nits, which is below the average of 300 nits for laptops and at least 400 nits for outdoor use, according to Laptop Mag.

* Conclusion :
AMOLED screens are among the most advanced and popular display technologies. They offer many benefits, including faster refresh rates, better viewing angles, higher contrast ratios, deeper blacks, lower power consumption, and longer battery life. However, they also have disadvantages such as higher cost, limited availability, risk of screen burn-in or degradation, color saturation or inaccuracy, and reduced brightness and visibility in bright environments.

Therefore, before buying a device with an AMOLED screen, you should carefully weigh these pros and cons, taking into account your specific needs and preferences. An AMOLED display can be a good choice if you value stunning graphics, vibrant colors, and long battery life.

However, if affordability, wide availability, long-lasting performance, true-to-life colors, and high brightness and visibility are more important to you, an AMOLED screen may not be the best option. .
