The difference between OLED and AMOLED lies in its basic structure. OLED consists of thin layers of organic compounds, while AMOLED has an additional thin layer of thin-film transistors. The organic material in the OLED helps to propagate light while AMOLED works on the active matrix system.


Organic Light-Emitting Diode (OLED) is an incredible display technology that uses organic materials for its display purposes.

Active Matrix Organic Light-Emitting Diode (AMOLED) is a new display technology that combines the use of organic material as well as the thin film of transistors.

What is OLED?

Organic Light Emitting Diode is a display technology used in our day-to-day electronic gadgets, uses organic compounds to emit light.

An OLED display works without a backlight. This is only because it emits visible light. This makes it thinner when compared to the LCDs.

OLEDs are flexible when compared to other display methods. This feature makes it most sought after by the mobile phone manufacturing industry.

The passive matrix OLED is overlooked as AMOLED has taken the best stride in terms of flexibility and energy consumption.


What is AMOLED?

AMOLED is the advanced display technology that couples the Active matrix system with the organic compounds that shall emit light.

AMOLED is in use since the year 2007. From then on, it has loomed large in several industries. Primarily because of its low-cost manufacturing methods as well as its energy consumption features.

AMOLED consists of thin layers of pixels that are made from organic materials. It generates light upon activation of electrical current. This is fed by the thin film of transistors that is present.

Thin Film Transistor backplane technology is highly critical in the manufacturing of AMOLED. The mode in which these AMOLEDs are manufactured makes it more flexible than the traditional OLED.

The refresh rate of the screen is a lot faster than the OLED. The display sizes can be large too. AMOLED enables a wide-angle view. This makes the televisions more conducive and electric.


Main Differences Between OLED and AMOLED

  1. The contrast ratio of OLED is high compared to the AMOLED.
  2. OLED has a few limitations, and one such is the display size. It is conducive only to the TVs, while AMOLED can be a lot flexible and can be used in foldable smartphones too.
