The AMOLED display matters

The AMOLED display matters

This is the term you know or will soon know, because it will be the display in the majority on your wearable devices, including smartphones.


The display for both Galaxy S8 and iPhone 8?

There are many rumours about the Galaxy S8 and iPhone 8 lately. People say the S8 and iPhone 8 will come with a curved display, which they call it “Super AMOLED”. Some so-called “insider” even said that Apple has ordered the AMOLED display to produce the iPhone 8.

So, what is the AMOLED all about? Someone says it is for making flexible or foldable smartphones soon. Wow, I can’t believe that my phone is “foldable”. However, if it happens, it will be cool because it sounds convenient to me.


What are the differences?

AMOLED is actually a kind of OLED. It means “Active Matrix Organic Light Emitting Diode”. The benefits of OLED come from its darkness. OLED is a screen with pixels made from an organic material that emits light whenever it’s fed with an electric current. It emits no light and no color when there is no current and so the black part can remain really “black”.

Another benefit from OLED is that some pixels are turned off to display black color, meaning it can save more power. AMOLED is an improved OLED that provides a faster response and a more accurate display.

The traditional display LCD being used in iPhone 7 relies on a backlight as the sole light source. The light is then polarized and filtered to display different colors on the screen. The backlight is always on. Sometimes, an LCD display is in a slight blue tint because it is based on a filtered blue backlight. We can imagine that OLED can produce a better display with lower power consumption.

Besides, without the rigid backlight, OLED display can be made of flexible plastic. The downside of OLED is that different pixels might degrade at slightly different rates, and so the display color balance might drift slightly over time, while LCD’s single backlight can remain a consistent color balance for long.

What is the next standard?

Rumors are saying that Galaxy S8 will sport a new Super AMOLED display. The resolution would be 11,059,200 pixels, much higher than the Galaxy S7, which is 7,372,800 pixels. What about the iPhone 8? Let’s wait and see.
