AMOLED Display technology

The display is one of the major components in any smart device, be it TV, smartphones, or smartwatches.

Most devices are incomplete without a proper display. And as we are moving towards a more advanced and digitally-connected world, the role of display becomes even more important.  And one display technology that is expected to play a key role is the AMOLED display.

For those who do not know, there are mainly two types of display: LED and LCD. While LCD displays have been here for a while, LED is relatively new.

OLED and AMOLED are parts of LED. The abbreviation AMOLED stands for Active Matrix Organic Light Emitting Diode. This is a type of OLED technology which uses anodes and cathodes for electron flow through a very thin film transistor (TFT) and colours are controlled by the tiny red, green and blue light-emitting diodes.

So whenever a current passes through each pixels, it can retain its charge in between refresh cycles, allowing for faster and more precise control.

The use of LED lights generally helps in making display thinner which in turn results in AMOLED display devices generally being slimmer. Another major benefit of these types of displays is that pixels can be switched off completely allowing for high contrast ratio and deep blacks.

The lack of other layers, which you generally find in LCD displays, also means that maximum amount of light can reach the display surface allowing brighter images and better viewing angles. AMOLED displays are also flexible in nature, and this with the control over individual pixels to save power, is why they are so often used in wearable devices such as smartwatches.
