POLED, AMOLED and OLED: what’s the difference between displays after all?

Today, there are many options when choosing electronic devices. And there are many people who take the subject of cell phone or TV screen material very seriously. Also: a particular choice can also mean: differences in color, description of pictures, resolution of photos, among several other factors.

In this article, we explain the differences between OLED, AMOLED and POLED displays so that you can choose your new electronic device assertively.

oled display

OLED displays take their name from the English term. this is an acronym Organic Light Emitting Diodestands for “organic light-emitting diode”.

Basically, images using this technology create images from self-leveling pixels. They have an LED made of organic material that produces light when a current is passed through it.

As a result, OLED displays are smaller, more flexible and thinner than older LED technology, which used liquid crystal in its composition. Colors are more vivid and when dark colors are transmitted, images they consume less energy – which can be a good advantage for those who want to conserve their cell phone battery.

Advantages of OLED

• The images on OLED screens are vibrant and contain a lot of contrast and the color called true black is highlighted;
• Because OLED pixels emit light in all directions, image viewing is improved in many ways;
• You images OLEDs tend to be thinner, lighter and more flexible;
• Since OLED technology only consumes power when turned on, displays are highly energy efficient and save battery power.

Disadvantages of OLED

• OLED displays tend to have a shorter lifespan compared to other displays. images;
• They are not very water resistant and are easily damaged when they come into contact with liquid.

AMOLED display

AMOLED technology means: Active Matrix Organic Light Emitting Diode – It stands for “Active Matrix Organic Light Emitting Diode”. Conversion uses an active matrix and a thin-film transistor (TFT) to control the flow of current to each pixel.

Created as an evolution view OLED and was first used in the BenQ-Siemens S88 mobile phone in 2006. An important difference from its predecessor is that the AMOLED screen adds the TFT layer to the OLED panel. Like this view It works with a matrix that controls pixels individually and determines which ones to connect or not.

AMOLED screen has no size limitation and consumes less energy. images OLED and LED. Usually used in mobile phones, laptopstelevisions, smart watchesas well as other devices.

Advantages of AMOLED

• any available viewwhatever its size;
• Economical (even more than an OLED screen) as it consumes no energy when viewing black;
• Offers excellent viewing angles on screens;
• Since it does not move the liquid crystals (as in LCD technology), it provides a very fast response time.

Disadvantages of AMOLED

• It has a shorter service life than the LCD screen, which is also commonly used in televisions;
• Relatively prone to screen burns;
• It is more expensive than other similar technologies due to its high production cost;
• Screen brightness can be limited by the manufacturer to reduce wear on the organic layer.

POST screen

Finally, we come to POLED technology, which is the meaning of its name. Plastic Organic Light Emitting Diode. That is, it also uses the technique of making use of light-emitting diodes, but replaces the glass substrate with plastic.

why does this happen the screen becomes more flexible, for example, it can be used in mobile phones and foldable monitors.

This new technology was first released in 2013 with the LG G Flex mobile phone. The structure of this material has been changed: instead of using a layer of TFT glass as in OLED technology, TFT plastic is used in addition to the already encapsulated OLEDs and a polarizer.

The result is a significant reduction in the thickness of the entire system compared to previous technologies. As a result, it is possible to manufacture thinner and lighter devices.

Advantages of POLED

• The main advantage is the flexibility of the system, made possible by the use of the plastic substrate. Therefore, it is possible to create foldable cell phones and curved monitors;
• As with previous technologies, it has low power consumption;
• The contrast between dark and light colors is excellent;
• Screens are highly impact resistant as they use plastic;
• It is a relatively inexpensive technology.

Disadvantages of POLED

• It has lower durability than its predecessors, such as LCD panels;
• in relation to view OLED may have worse image quality;
• Screens can be scratched more easily than their glass counterparts;
• Organic decomposition can also cause screen burn.
