OLED vs AMOLED- What’s the Difference

There is a lot of confusion out there when it comes to OLED and AMOLED displays. So, what is the difference between the two? Well, first and foremost, OLED displays are made up of individual light-emitting diodes (LEDs), while AMOLED displays use a backlight that spreads light across an entire display panel.

Main Difference

OLEDs are also known for their high contrast ratio and wide viewing angles, while AMOLED displays usually offer better color reproduction and more consistent image quality. But beyond those differences, the two technologies actually have a lot in common.

What is Oled and how does it work?

A few years ago, OLED displays started appearing in high-end smartphones. They offered several advantages over traditional LCD displays, such as brighter colors and deeper black levels. More recently, active-matrix OLED (AMOLED) displays have become popular in flagship Android smartphones. So what’s the difference between OLED and AMOLED displays? The main difference is that OLED displays use a passive matrix structure, while AMOLED displays use an active-matrix structure.

This means that AMOLED displays are more responsive and can offer higher resolutions than OLED displays. Another difference is that AMOLED displays typically use a metallic cathode layer, while OLED displays typically use a carbon-based cathode layer. This can affect the lifetime of the display and how it performs in cold weather.


  • OLEDs are made of organic materials, making them cheaper to produce than traditional LCD displays.
  • They also offer a wider viewing angle and better contrast ratios.
  • OLED screens are also thinner and lighter than LCD screens.

What is AMOLED?

The terms OLED and AMOLED are often used interchangeably, but they are not the same. OLED stands for organic light-emitting diode, while AMOLED stands for active-matrix OLED. AMOLED is a specific type of OLED display that features a matrix of pixels that are all controlled by a single transistor.

This allows for sharper images and improved contrast ratios when compared to traditional OLED displays. Amoled, or active-matrix organic light-emitting diode, is a display technology used in smartphones and other electronic devices. It differs from traditional LCD displays in that it emits light from organic materials, rather than backlighting. This makes for a thinner display with improved contrast and brightness.


AMOLED displays are often considered to be the best mobile displays currently available. They offer a number of features and advantages over other display technologies, such as LCDs. Some of the key benefits of AMOLED displays include:

1. Brighter colors and better contrast – AMOLED displays offer brighter colors and better contrast than LCDs. This is because AMOLED pixels emit their own light, while LCD pixels rely on a backlight that can wash out colors and affect contrast.

2. More vibrant colors – AMOLED displays are also known for their more vibrant colors, which is due to the nature of how OLED pixels work. In an LCD display, each pixel is divided into three subpixels (red, green, and blue), and each one emits a different color of light. This creates some level of overlap, which can dull colors.

Key Differences Between OLED and AMOLED

In recent years, there has been a dramatic improvement in phone display technology. The two most popular types of displays are OLED and AMOLED. Both have their pros and cons, but what’s the difference between OLED and AMOLED?

  • The main difference between OLED and AMOLED is that AMOLED screens use a backlight, while OLED screens don’t. This means that AMOLED screens are brighter and more power-efficient than OLED screens. However, OLED screens have better contrast ratios and viewing angles than AMOLED screens.
  • Another difference between OLED and AMOLED is that AMOLED displays can show more colors than OLED displays. This is because each pixel on an AMOLED screen can be lit up individually, while all the pixels on an OLED screen are lit at once.
  • OLED displays are brighter and have a more even backlight.
  • They also have a higher contrast ratio, which means that images look crisper and blacks look blacker.
  • However, AMOLED displays are more energy-efficient and can be made thinner than OLED displays.
  • Additionally, AMOLED displays can show a wider range of colors, making them better for displaying photographs or other images with a lot of color variation.

Comparison Chart Between OLED and AMOLED

Comparison OLED AMOLED
Basic Structure OLED contains only the thin layer of organic compound that facilitates the display function AMOLED contains the organic layer as well as a thin layer of transistors that shall combine in its display function.
Power Consumption Higher when compared to AMOLED Lower when compared to OLED
Flexibility Less Flexible in usage Highly flexible
Cost of Production Very Less Relatively higher than the OLED
Refresh Rates Slightly higher than the AMOLED Significantly less than a millisecond


In conclusion, OLED and AMOLED displays are both great technologies, but they have their own unique advantages and disadvantages. For example, OLED displays are brighter and have higher contrast ratios than AMOLED displays, but AMOLED displays are more power-efficient and can be thinner than OLED displays. So, which technology is best for you depends on your specific needs and preferences.
