What does AMOLED screen mean?
AMOLED is a type of OLED display and an acronym for Active Matrix Organic Light Emitting Diodes. The OLED part means that the display uses LEDs and an organic compound made of carbon and other substances to light up and display colors. The AM part of AMOLED, which comes from Active Matrix, represents the electronic implementation behind the screen.
A Quick Primer on OLED and AMOLED
Displays using organic light-emitting diodes (OLED) incorporate organic materials that light up when in contact with electricity. The active-matrix aspect of AMOLED sets it apart from OLED. AMOLED, then, is a kind of screen technology that includes not only a way to display light but also a method to detect touch (the “active-matrix” part). While it’s true that this method is a part of AMOLED displays as well, super-AMOLEDs are slightly different.
Here’s a quick summary of some pros and cons of AMOLED displays.
Pros:
- Wide viewing angles
- Support for a large range of color
- Great display of black
- Long battery life if using darker colors
Cons:
- Oversaturated images
- Shortened battery life when displaying vibrant colors
AMOLED displays are known for being able to render a deep black color when needed, a huge plus on any display and something you’ll notice right away when comparing with your standard IPS (in-plane switching) LCD (liquid crystal display). The benefit is obvious when watching a movie or viewing a picture that’s supposed to contain ‘true’ black.
AMOLED technology includes a layer behind the OLED panel that gives light to each pixel instead of using a backlight as LCD displays do. Because each pixel can be colored on an as-needed basis, pixels can be dimmed or turned off to make a true black instead of the pixels being blocked from receiving light (as with LCD).
This also means that AMOLED screens are great for displaying a huge range of color; the contrast against whites is infinite (because blacks are absolute black). On the other hand, this amazing ability makes it easier for images to be too vibrant or oversaturated.
AMOLED vs. IPS LCD
IPS LCD stands for In-Plane Switching Liquid Crystal Display, and it is an improvement of the LCD technology. IPS LCD offers more brightness, contrast, and colors that look more natural than a traditional TN (Twisted Nematic) LCD screen, as well as much broader viewing angles. However, all the pros and cons we talked about in the previous section from this article still apply. There is no clear winner when it comes to AMOLED vs. IPS LCD, as both technologies have their strengths and weaknesses.
The benefits of AMOLED
The main benefits of AMOLED are the pure blacks, bright colors and strong contrast ratio that this type of screens can give you. If you want all that, you should look into buying devices with AMOLED screens.
Do you want your devices to use AMOLED displays?
Now you know what AMOLED stands for and why it is a great technology. You also know why nobody can say that it is the best display technology and why other display technologies such as IPS LCD compete with it. Do you want the true blacks and bright colors offered by AMOLED? Or do you prefer the cheaper LCD? Share your thoughts in the comments below.
Super-AMOLED vs. AMOLED
AMOLED is similar to Super-AMOLED in not only name but also in function. In reality, Super-AMOLED is identical to AMOLED in all ways but one, but it’s that one way that makes all the difference.
The two technologies are the same in that devices using them can incorporate light and touch sensors so that the screen can be read and manipulated. The layer that detects touch (called the digitizer or capacitive touchscreen layer), however, is embedded directly into the screen in Super-AMOLED displays, while it’s an entirely separate layer on top of the screen in AMOLED displays.
This might not seem like a major difference, but Super-AMOLED displays carry many benefits over AMOLED displays because of the way these layers are designed:
The device can be thinner because the technologies for display and touch are on the same layer.Higher contrast, plus the lack of an air gap between the digitizer and the actual screen, yield a crisper, more vivid display.
Less power needs to be supplied to a Super-AMOLED screen because it doesn’t generate as much heat as older screen technologies. This is due, in part, to the fact that pixels are actually turned off and therefore not emitting light/using power when displaying black.The screen is more sensitive to touch.
Light reflection is reduced because there aren’t as many layers, which makes reading outdoors in bright light easier.A higher refresh rate helps speed up the response time.
What is the difference between OLED and AMOLED?
OLED screens can use two types of electronics to control the pictures they display: PMOLED and AMOLED. Thus, there is no difference between OLED and AMOLED, as AMOLED is an OLED display.
There are differences, however, between PMOLED and AMOLED. PMOLED comes from Passive Matrix OLED, and it is an electronics implementation that does not have a storage capacitor. AMOLED, as we already know, stands for Active Matrix OLED and its electronics driver has a storage capacitor.
Is AMOLED better than LCD?
Some people think that AMOLED is better than LCD, while others argue about the opposite. However, there are pros and cons to both these display technologies
AMOLED displays can light up or turn off each of their pixels independently, and that means that they can offer much better and more natural colors than LCD screens. LCD (Liquid Crystal Display) screens do not light up their pixels independently: they use a backlight and a panel of pixels that actually block the white light behind them to make colors. This technology cannot offer the same natural colors as AMOLED can.
Also because of the different way they display colors, AMOLED and LCD screens are not the same when it comes to the level of brightness they can offer. Each of the pixels on an AMOLED display has its own tiny light source, while LCD have backlights that are usually provided by lamps behind the display. Thus, LCD screens tend to offer higher brightness levels than AMOLED displays.
Consequence of AMOLED and LCD
Another consequence of the way AMOLED and LCD screens light their pixels, is that AMOLED offers true blacks (by turning off pixels independently), while LCD offers cleaner whites (because it has a stronger backlight).
When talking about the use of AMOLED or LCD on a screen powered by a battery, power consumption is an issue. Because AMOLED can completely turn off pixels independently, you might assume that it is more power efficient than LCD. However, that depends on how you use your device. AMOLED displays need less power than LCD screens when the images they display do not have much white but consume more power when they display a lot of white. When there are lots of bright colors to be displayed, AMOLED needs more power to turn on its pixels. On the other hand, LCDs need the same constant amount of power regardless of the type of images they display, because their backlight is always on.
AMOLED screens have an organic component in their pixels, while LCDs do not. That means that the lifespan of AMOLED screens tends to be lower than that of LCDs.Because OLED technology is pricey, AMOLED displays are more expensive to manufacture than LCDs.
NOTE;
So i am using and like only super Amoled and i was a big samsung fan so i know the quality of the display and its color is also very unique so guys no worry just select the AMOLED display its really better than LCD and IPS.
