YOGYAKARTA - AMOLED screens are a type of screen that is widely used for smartphone devices. However, there are still many smartphone users who do not know what AMOLED screens are and the difference is with other screen types.

AMOLED screens are not only used on mobile phones, but also for other electronic devices such as laptops and smartwatches. Phones with AMOLED screens are widely popular because this screen has a number of advantages, such as displaying a clearer and sharper color.

Many electronics manufacturers then use AMOLED screens for cell phones or laptops. This screen does have a higher price, but is proportional to its quality. Therefore, before buying a smartphone, make sure you understand what AMOLED screens are and their advantages are.

The AMOLED screen is a screen produced with organic light-emitting diode or OLED technology. OLED is a type of electroluminescent technology, which is a special paneled screen with organic elements that can emit light in response to electric currents.

The way OLED is used on display panels requires a transition of individual organic compounds, each representing individual pixels or image elements. AMOLED screen technology deals with this through an active matrix switch by installing each pixel into a transitor and capacitor.

The combination of OLED technology will make smartphones capable of producing high quality images and have a sharp color composition. This advantage makes many smartphone manufacturers choose the AMOLE screen for their outgoing phones.

There are four layers in AMOLED screen technology, namely Anode Layer, Middle Organic Layer, Cathode Layer, and Circitry. Each layer has its own function.

Middle Organic Layer is a positive polar layer whose function is to create an electron hole. The electron hole will throw away electrons when the screen is electrified by electricity.

Middle Organic Layer is a central organic layer consisting of two parts, namely the channel layer and the transmitter layer. This screen layer is made of organic molecules.

The Cathode Layer is a negative polar layer whose function is to insert electrons when the screen is electrified by electricity. The Cathode Layer layer can be transparent or not, depending on the type of OLED technology used.

Circitry is a lower layer that functions as an OLED display base. This layer contains strands and is made of glasses, paper, plastic, and foils.

The AMOLED screen has a number of advantages so that this screen is widely chosen for phones and laptops. Here are some advantages from the AMOLED screen that will be enjoyed by users.

AMOLED screens have a high contrast ratio. The contrast ratio is higher than technology in other types of LCD, such as TN and IPS. Each pixel or diode in this screen is made of organic materials capable of producing colors and emitting better light.

The AMOLED screen is also liked because it offers quality displays. In addition to being brighter, the image produced by this screen seems more real than the appearance on the TN and IPS screen types. In addition, this screen also has a better angle or point of view than the upper class IPS panels. So when viewed from a tilted or sided position, the appearance does not change and remains bright.

Another advantage of the AMOLED screen is that it has a thin dimension. This screen panel has a thin organic plastic layer, which is about 100 to 500 nanometers. In addition, this screen plastic material is much lighter than the rigid crystal layer on the LCD screen. With this dimension, the AMOLED screen is able to produce brighter light.

The level of power consumption on AMOLED screens is also much lower. This screen consumes less power than other types of screens, such as LCD and LED. This screen is capable of emitting light without producing too much heat energy. With this advantage, this screen user can be more battery efficient.

That's a review of what AMOLED screens are and their parts are. Currently, many smartphone manufacturers choose to use this screen because it has many advantages. Various smartphones have implemented this screen, such as Samsung, Xiaomi, OPPO, VIVO, and so on.
