AMOLED vs OLED: Which Is Better And Why?
Display technology has evolved a lot since the introduction of LCDs. While LCD and OLED displays have many differences, there is not much difference between AMOLED and OLED.
Over time, the purpose of using mobile phones or Smartphones has changed. Comparatively, it has now become a basic necessity of every individual. Smartphone has dramatically transformed the lives of individuals. It has now become a mini-computer that everyone carries in their pocket. Instead, you can have multiple things at your fingertips in a few seconds. While there are plenty of things to look for, vs OLED is also a part of it.
Before purchasing any Smartphone, everyone goes through a list of specifications. This list includes display type, screen size, battery backup, supported operating system, total internal memory, and many others. Today, we have brought a comprehensive study of the significant display technologies available nowadays.
What are OLED displays?
It stands for Natural Light-Emitting Diode, a type of LED technique that utilises LEDs wherein the light is of organic molecules that cause the LEDs to shine brighter. These organic LEDs are in use to make what are thought to be the best display panels in the world.
When you make an , you put organic films among two conductors to make them. As a result, a bright light comes out when electricity is used-a simple design with many advantages over other ways to show things.
OLEDs can be used to make emissive displays, which implies that each pixel can be controlled and emits its very own light. As a result, OLED displays have excellent picture quality. They have bright colours, fast motion, and most importantly, very high contrast. Most of all, “real” blacks are the most important. The simple design of OLEDs also makes it easy to create flexible displays that can bend and move.
1. PMOLED (Passive Matrix OLED)
PMOLED stands for Passive Matrix Organic Light Emitting Diode. The PMOLEDs are easy to find and much cheaper than other LEDs, but they cannot work for a long duration as their lifespan is very short. Therefore, this type of display is generally for small devices up to 3 inches.
2. AMOLED
AMOLED stands for Active Matrix Organic Light Emitting Diode. This type of display is generally for large platforms. It contains TFT, which further consists of a storage capacitor. It also works on the same principle as OLED displays.
Advantages of OLED displays
There are various advantages of OLED. Some of them are as follows:
● It provides a good quality display.
● It is cost-effective.
● It is much brighter than LEDs.
● They do not require backlighting.
● It has a much faster response time as compared to the traditional LCDs.
Disadvantages of OLED displays
There are very few limitations to OLED. Some of them are as follows:
● The lifespan of OLEDs is much shorter as compared to LCD, LED and PDP display technologies.
● The OLEDs have variations in colour balance.
● It does not provide resistance against water. Water can easily damage the OLED displays.
What are AMOLED displays?
AMOLED offers no restriction on the size of the display. The power consumption of is much less than other display technologies. The AMOLED provides incredible performance. It is thinner, lighter, and more flexible than any other display technology like LED, or LCD technology.
The AMOLED display is widely used in mobiles, laptops, and televisions as it offers excellent performance.
Advantages of AMOLED
There are various advantages of AMOLED. Some of them are as follows:
● It can be easily embedded into a display of any size.
● It has a much faster refresh rate as compared to PMOLED.
● They are also used in industrial applications.
● They offer much better viewing angles as compared to the IPS LCD.
Disadvantages of AMOLED in AMOLED vs OLED
There are very few limitations to AMOLED. Some of them are as follows:
● The quality of the display degraded with time. This is one of the biggest disadvantages of the AMOLED display.
● The AMOLED display is very likely to screen burn-in.
● The AMOLED displays are very costly as compared to other display technologies.
So far, we have discussed OLED and technologies. Now, we will look at some of the differences between OLED and AMOLED display technology:
Differences between AMOLED vs OLED Display Technology
1. Technology — AMOLED vs OLED
OLED comprises thin layers of the organic component, which emits light when the current passes through it. In this technology, each pixel transmits its own light. On the other side, AMOLED consists of an additional layer of thin-film transistors (TFTs). In AMOLED, the storage capacitors are used to maintain the pixel states.
With varying technologies, first came the OLED.
While the technology is different among various manufacturers, Samsung’s edge AMOLED displays use plastic substrates with poly-Si TFT technology similar to how LG uses it in their POLED technology. This technology is what makes the possibility to build curved displays using an active-matrix OLED panel.
2. Display — AMOLED vs OLED
OLED display much deeper blacks as compared to the AMOLED displays. You cannot see the screen in AMOLED display under direct sunlight. The AMOLED display quality is much better than the OLEDs as it contains an additional layer of TFTs and follows backplane technologies.
The AMOLED displays are much more flexible as compared to the OLED display. Hence, they are much more costly than the OLED display.
3. Working — AMOLED vs OLED
The OLED devices are simple solid-state devices consisting of a thin layer of organic compounds in an emissive electroluminescent layer where the electricity generates.
These organic compounds are present between the protective layers of glass or plastic. Comparatively, AMOLED comprises an active matrix of OLED pixels along with an additional layer of TFTs. This extra layer is responsible for controlling the current flow in each pixel.
4. Contrast Ratio — AMOLED vs OLED
The OLED display offers a high level of control over pixels. Hence, it can be turned off completely, resulting in an excellent contrast ratio compared to the AMOLED displays and less power consumption. On the other side, AMOLED has faster refresh rates than OLEDs. Also, they offer a tremendous artificial contrast ratio as each pixel transmits light but consumes more power than OLEDs.
5. Display size — AMOLED vs OLED
OLED displays are comparatively much thinner compared to the LCDs. Hence, it provides more efficient and bright presentations. In addition, OLED offers support for large display sizes compared to the traditional LCDs. AMOLEDs remove the limitation of display sizes. one can fit it into any display size.
Putting all the points mentioned above in view, the key difference to understand appropriately is that POLED is an OLED display with a plastic substrate. On the other hand, AMOLED is Samsung’s word for its display technology which is mainly for marketing. Therefore, most phone manufacturers having AMOLED displays mean that they are using Samsung displays. It is as simple as that. To add to that, all the curved display technology is made possible because of the usage of plastic substrate.
So, based on the points mentioned above, the difference between OLED and AMOLED displays, you can choose any of the two display technology at your convenience. Both are good, offer excellent performance, and are customised according to your requirements.
The AMOLED display has a higher quality than OLEDs since it has an additional layer of TTs and uses backplane technologies. When compared to OLED screens, AMOLED displays are far more flexible. As a result, they are substantially more expensive than an OLED display.
Conclusion in AMOLED vs OLED
Smartphone displays have advanced significantly in recent years, more so than most people realise in this technological age. Display screens are similar to windows in the mobile world, which has seen a tremendous transformation in innovative products in the last several years. People have gotten more selective when buying a phone in recent years, and although all of the functions are important, the display is always the most noticeable.
Major smartphone manufacturers attempt to provide their consumers with the most delicate devices possible that incorporate the most up-to-date technologies. In , AMOLED is a type of OLED and a more prominent example of both OLED and POLED, so there’s no debate about which is superior.
