AMOLED-display. Which is better: AMOLED or Super AMOLED?

Smartphones with AMOLED-display become more and more popular. But what are the advantages of such a display?

It is easy to see that the AMOLED screen is more expensive IPS counterparts. What is connected with higher cost? Is it possible to distinguish the display, built on technology AMOLED, screens of a different type? Why is such an LCD panel rarely found outside of products the South Korean company Samsung? The answers to these questions in this article.

Design of AMOLED screen

The acronym AMOLED hidden transcript “Active Matrix Organic Light-Emitting Diode”. This means that the matrix built on the basis of organic light-emitting diodes, while it is active. Each pixel is lit independently, resulting in separate layer with illumination is not required — this reduces the thickness of the panel, and reduces power consumption.

Almost any AMOLED screen has the following structure:

  • The top layer — the cathode;
  • Below you’ll organic layer with LEDs — no air gap no;
  • Yet below is a matrix of thin-film transistors involved in the management of diodes;
  • Followed by the anode layer;
  • All this lies on a substrate of silicone, metal or some other material.

The structure of the AMOLED screen

The arrangement of the led subpixels in AMOLED displays may be different. Samsung has long used PenTile — stagger (middle — blue, the sides of two green, two red). It is the position of subpixels positive impact on energy consumption.

AMOLED or Super AMOLED: which is better?

In smartphones Samsung used screens, made by technology Super AMOLED. What are the main differences between these displays? Initially, the prefix “Super” meant the absence of the air gap — that the South Korean company managed to get rid of such in 2010. But now it can boast and ordinary AMOLED screens manufactured by other companies. Consequently, the Super AMOLED is now a marketing “trick” South Korean manufacturer. That is, between AMOLED and Super AMOLED, you can put the equal sign.

It should be noted that Samsung produces the highest number of AMOLED panels. The South Koreans have learned to fully Flex their creations (to do this without a separate layer with lighting much easier). Be sure all smartphones with AMOLED-display, the edges of which are curved, are manufactured using a Korean matrix. Own factory for the production of screens from organic LEDs is going to open the Apple, but it will happen no earlier than 2020.

The main advantages of AMOLED panels

The physical properties of the matrix consisting of organic LEDs, such that the screen may have a tiny thickness. In particular, it is especially important for smart watches and fitness bracelets, the physical dimensions of which should not be large.

But the main plus any OLED screen (including variations of it) is low power consumption. Each pixel of such a display is lit independently. It turns out that the largest energy consumption will be in the moment when the entire screen displays a smooth white color. And if some region needs to display dark colors, they glow noticeably dimmer, therefore the battery consumption is reduced.

Darker than displayed on the picture — the less energy is consumed.

High contrast — another undoubted advantage of such screens. This is due to the same ability of the pixels glow on their own. For example, under IPS panel hides the substrate from the LEDs that illuminate including black. Here also this does not happen.

Differences in terms of the contrast are immediately noticeable

Also it is due to this picture on AMOLED screen is well visible even under bright sunlight. IPS technology allows you to see something on display in a clear day, just remove the backlight brightness, which leads to sharply increasing energy consumption.

Phones with AMOLED-display

As mentioned above, organic LEDs “you” only Samsung. But this does not mean that the manufacturer doesn’t sell their screens to someone else. In particular, a 6-inch AMOLED panel is part of the popular smartphone OnePlus 5T. The resolution of this screen is 2160 x 1080 pixels, and the width of the side frames is minimized.

Is based on organic led screen has and Meizu Pro 7. This device is much more compact — diagonal set here the display is only 5.2 inches and a resolution of 1920 x 1080 pixels. A distinctive feature of the device is the presence of a second screen located on the rear panel, right under the dual camera. At its creation also used AMOLED technology.


For the AMOLED displays of the future, that’s for sure. Such displays do not have serious shortcomings, giving an image with better colour reproduction and maximum viewing angles, while spending a very small amount of electricity. The only problem is the higher cost of such panels. Her results are far from the record the yield rate of products. Also can not mention about the high rate of production — alas, one of Samsung to satisfy the demands of the smartphone market is extremely difficult.
