Technologies Compared

OLED or AMOLED – The Ultimate Display Leader

So the first-ever mobile phone where actually 0G and even calling mobile is not actually correct because they were chunky boxes and with massive box receiver they were very heavy. Than 1G rolled out. 1g was the first time when the general public could make a phone and even that devices were about 1 kilogram.

2G took the 2.4 KBPS speed of 1g and made it 15 times faster about 40 KBPS which made the phone not just able to call but also send text and even picture messages.

 3G was 50 times faster than 2G and that brings a revolution in technology the only reason for today’s Fame of social media like InstagramFacebook, and various application like ola, Uber and games is because of 3G.

 Actually, 3G was so cool that Apple named one of his iPhones, the iPhone 3G just to promote its availability and to support.

  But when 4G came out it was about 50-500 times faster than 3G. You can do the unthinkable, you can stream Netflix at 1080p, you can play multiplayer games with 100 others on the same map it was all about a rich multi-media experience. 

What 5G can do?

Basically, a good 5G signal means instant sharing it means browsing the internet without any buffering and you can even control the robotic control machine.

Increased Display Sizes

Increased Display Sizes

If I talk about display,in feature phone the screen was very small of 3.5 inches(HVGA Display) and the quality was very poor since they were made of fiber material. The first major update in the field of display was made in iPhone in 2007 from there all the companies tried to improve their screen quality and size which enables users for multitasking on phones like computers. Since the launch of the multitasking facility, it was necessary to have a big screen on the smartphone.

With the increase of screen sizes companies on the other hand was working on on-screen protection so that it can resist the rough scratch and falling down temperateness. These protections were more improved when the companies introduced the Corning Gorilla Glass technology to secure the screen.

Now, these technologies are more advanced in this field and Samsung had also introduced the folding screen. Here I will be only talking about the OLED and AMOLED screens only.


OLED(Organic Light-Emitting Diodes) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When an electrical current is applied a bright light is emitted. OLEDs are emissive that do not require and so are thinner and more efficient than LCDs display(which does require a white backlight).

 OLEDs are not only thin and efficient but it produces the best quality ever provided on screen, in near future OLED display can be used to produce foldable, stretchable, rollable and even transparent screen. We have already come across the Samsung Foldable smartphone launched recently. The base foundation of foldable display in T.Vs and Smartphones are also based upon it. In, short it can be said that OLED displays are the future of upcoming technologies, and we can not even predict the upcoming use of OLEDs screen.


There is wide range of advantages of OLED over LCD. Some are mentioned below;
  • OLED is more enhanced, efficient, brighter, contrast, and a wider color range even with a super-fast refresh rate.
  • They are made of organic components that can be regenerated and not even harmful to the environment.
  • LCD consumes a higher power than OLEDs.
  • OLEDs are durable and can operate with a boarder range with higher temperature.
  • OLED is durable.
  • Very few stuff are needed for OLED than LCD.

OLED Working Mechanism

Do you remember the T.Vs in 1940s which was powered by cathode ray tube (CRTs) and that were very heavy, then LCD came up which was thinner than it can mount over the wall and display light enough to build in the portable gadgets like cellphones, watches, and tabs. But display made with OLED technologies are even better. They are super light, paper-thin, and theoretically flexible enough to print onto clothing.

The working mechanism of OLED is quite similar to LCD. So let us understand the working principle of LED. A LED consists of two slabs of semiconductor material (mainly Silicon& Germanium are used) and among which is electron-rich or have excess electron(called n-type semiconductor) and while the other is rich in the proton( called p-type). When these two slabs are joined together we get an electrically neutral area at their junction where the excess electron and protons jump over each other slabs and cancel the charges.

However, when you connect these two slabs using electrical contact and passes an electrical current through it the surplus electron from the n-type flow and release proton from p-type which emits light.

OLED works on this same principle but they use organic molecules in the n-type and p-type conductor.


AMOLED is a display technology and stands for Active Matrix Organic Light-Emitting Diode. It is a type of OLED display used in the smartphone. The oft-cited advantages of AMOLED displays they work pixel-by-pixel produces brighter color.

The AMOLED display is an improved version of OLED display introducing Thin Film Transistor(TFT) layers that enables greater control over light emitted by OLEDs. The TFT layers provide an enhanced “active matrix” of light control, accounting for the ‘AM’ in AMOLED.

AMOLED Working Mechanism

“Active matrix(AM) OLED displays stack cathode, organic, and anode layers on top of another layer on top of another layer- or substrate- that contain circuitry. The pixels are defined by the deposition of the organic materials in a continuous, discrete “dot” pattern. Each pixel is activated directly. A corresponding circuit delivers voltage to the cathode and anode materials, stimulating the middle organic layer.”

AMOLED pixels turn off and on more than three times faster than conventional motion picture film.

AMOLED Legacy over OLED

  • AMOLED is more clear than the OLED display.
  • In direct sunlight, OLED screens are not visible but AMOLED is visible that is why it is used in smartphones.
  • AMOLED support in-display fingerprint and in-display camera whereas OLED are incapable.
  • Since AMOLED works pixels by pixels , hence the power consumption is very low as Compared to OLED.
