AMOLED vs OLED: Which Is Better Display for Mobile Phones
Before comparing the difference between AMOLED and OLED displays, let’s first take a quick look at the other types of displays used in our electronics to understand better how display technology evolved into what it is today.
Cathode ray tube (CRT screen)
It all starts here. Do you remember PC monitors with a large volume tube on the back? These monitors use CRT or cathode ray tube screens. Back then, the screens in our electronic devices weren’t as good as we have today. As mentioned above, devices using CRT screens are too bulky, too heavy, ugly, and very unhealthy for the eyes due to increased radiation.
However, this technology is one of the most advanced of its time and has been used for several years before being replaced by a much better-known technology as LCD.
Liquid crystal display (LCD screen)
The LCD screen solved some of the more well-known problems with CRT displays, such as the aesthetic problem and providing a better and much safer display. Unlike the CRT, the LCD screen uses a much thinner screen that allows the manufacturer to use it in large electronic devices such as televisions and personal computers and smaller devices such as cell phones. It is also a low-cost technology that makes it one of the most preferred screen types over other types of magnifying screens (such as plasma screens) throughout its lifetime.
As mobile devices become the newest and hottest trend in the modern technology world, the LCD screen has played an essential role in this trend. Most of the world’s mobile devices used an LCD screen at the beginning of their popularity.
Thin-film transistor LCD (TFT display)
As the LCD screen plays a vital role in the development of mobile phone technology, a variant called the Thin Film Transistor (TFT) has been introduced to the mobile world. TFT is an LCD, but unlike a typical LCD, the TFT variant provides better image quality and contrast. It also uses less power than a regular LCD and is significantly faster in terms of refresh rate. However, the TFT screen is less compatible when exposed to direct sunlight, making it difficult to see when you take your device outside. It also has a big problem with consistently providing better viewing when viewed from different angles. In other words, the TFT screen can only be viewed from a certain angle and will not perform well when viewed from one side or another angle.
In-plane transition LCD (IPS screen)
To address the limitations of a TFT screen, a new and better LCD variant has been introduced, and this is the IPS screen. In general, the IPS screen provides a better image quality with no matter which angle you view the device from.
Usually, the TFT screen should be viewed from the front or at an angle to get a better view. IPS addresses this issue by providing better image quality even if you are looking at the device from the side of the top or from the angle you prefer. It is also faster in terms of response time and provides much better visibility with outdoor lighting.
Light-emitting diode (LED display)
We are often confused about the LED screen and how different it is from the LCD screen. As described on the Digital Trends website, the answer to this is that an LED is just another variant of an LCD. According to this site, the appropriate term for this type of LCD screen is “LCD screen with LED backlight”. Yes, you heard it right; the LED screen is simply an LCD screen that uses LEDs as the screen’s backlight.
The reason for using LED is that it provides better brightness and illumination to the screen, and is also more efficient, and consumes less power. Now that we have come to the point of LED compatible displays, some technology variants have been introduced that promise much better, more precise, energy-efficient, and cutting-edge technologies. In other words, we are in an age where LED screens are beginning to dominate our technological world.
Organic Light-Emitting Diode (OLED Display)
According to the Tom’s Guide website, OLED technology uses organic compounds to create colours. I think that’s why it’s called an organic light-emitting diode. This type of technology produces more intense colours and distinct contrast. LG is one of the known users of this type of display in its televisions.
OLED technology is brighter, more energy-efficient, thinner, and produces better contrast than LCD screens. One of the essential features of an OLED display is its ability to create a true black. Unlike the LCD screen, OLED does not use a backlight, so it is thinner and quickly wrapped. High-tech phones are already using OLED displays such as the Huawei P30 today.
Key point: OLED is not an LCD type display using LED backlighting. OLED is an entirely different technology that is considered better and more efficient than LCD.
Active Matrix Organic Light-Emitting Diode (AMOLED)
One of the most popular and sought-after displays today is AMOLED. You guessed it right; an AMOLED screen is a kind of OLED screen. OLED has a limitation; it has some restrictions on screen size, while AMOLED can be applied to any screen size.
AMOLED displays use TFT on OLED tap, remember that one of the advantages of the TFT screen is its faster response time, the AMOLED display inherits this feature, but unlike the original TFT, AMOLED offers better brightness and image quality. . However, it also inherits one of the TFT screen’s problems as it is barely visible when exposed to external lights.
Again, OLED provides better contrast, true blacks, and more efficient power consumption, while AMOLED offers a faster response rate and removes the limitations in screen size, which are OLED’s main problem. However, both screens are already excellent than the previous types we mentioned above, and both offer much better displays.
Super AMOLED is the real deal today because of its built-in touch functionality. It still offers a vibrant screen; it’s thinner and lighter, and more energy-efficient. And it is already easily visible when it exposed to direct sunlight. It is perfectly adaptable to a variety of lighting environments and has an impressive contrast ratio.
Samsung is one of the primary users of Super AMOLED as most of its flagship phones are equipped with this impressive technology. Originally the only downside it sees for AMOLED for all other OLED display types is that it burns out over time. But of course, there are some ways users can prevent this. For my part, I am using a Samsung A50, and I am impressed with the Super AMOLED display.
I compare it with the old iPhone SE, and it has an IPS screen. The difference is noticeable. I also reached Super AMOLED with Huawei P30’s OLED display, and Super AMOLED is more vibrant and unique.
As a result, Super AMOLED offers a better and more efficient display. However, it is expected to wear out over time, but there are several ways to prevent it from wearing out and make sure it doesn’t wear out that easily. OLED is also a better option, but Super AMOLED offers a faster refresh rate if you like gaming. The IPS screen is not yet in the game, and the iPhone still uses it on most of its phones, which is not a bad option. But really, the trend is now in OLED, and it didn’t disappoint.
