Difference Between OLED And AMOLED

Table of Contents

The main difference between AMOLED and OLED is that OLED comprises thin layers of organic compounds, whereas AMOLED also comprises an extra tiny layer of thin-film transistors. The organic component in OLEDs aids in light propagation, while AMOLEDs use an active matrix structure. AMOLED displays have superior video quality than OLED displays because they have an extra layer of TTs and utilize backplane technology.

What Is OLED?

OLED stands for Organic Light Emitting Diodes, which operate similarly to traditional diodes and LEDs but use a series of thin organic sheets instead of semiconductors to generate rich, brilliant colors and considerably deeper blacks.

Compared to standard LED displays, the organic compounds' ability to create light in response to current passing through them may not appear like a significant advancement. In contrast to LEDs, OLED displays are thin, more flexible, and microscopic, so small that millions of them can be viewed as individual pixels, creating stunning visuals.

The secret to the OLED's superior image quality is that each small pixel generates its own light dependent on the amount of current that flows through it. It creates excellent deep blacks to give precise colors and achieve an infinite contrast ratio.

AMOLED stands for Active Matrix Organic Light Emitting Diode and employs an active matrix system with a thin film transistor attached to regulate the flow of current to each pixel rather than a passive matrix technology. AMOLED is OLED with an extra layer of semiconducting compounds to more swiftly activate each pixel. 

To provide a superb viewing experience, it exerts a great deal of control over each pixel. The vibrant display of the AMOLED is made possible by TFT backplane technology. The power consumption is much lower than other display technologies because of the greater refresh rates.

AMOLED displays are mostly used in smartphones, laptops, and TVs; in other words, anything portable has to fit fantastic display quality onto a very flexible screen for amazing results. It's a bundle of outstanding performance, power efficiency, and image quality.

Differences Between OLED And AMOLED


The organic compounds, made up of tiny layers that emit light when current flows through them, make up an OLED. Each pixel with this technology sends its own light. On the other hand, AMOLED comprises an extra layer of thin-film transistors. The storage capacitors in AMOLED are utilized to preserve the pixel states.


A tiny organic compounds layer in an emissive electroluminescent layer, where the power is generated, makes up the OLED devices, which are straightforward solid-state electronics. These organic compounds are between the layers of glass or plastic that serve as protection. In contrast, AMOLED has an extra layer of TFTs and an active matrix of OLED pixels. This additional layer manages the current flow in each pixel.


OLED displays have substantially deeper blacks than AMOLED displays do. Under direct sunlight, the AMOLED display screen is difficult to see. Because it has an extra layer of TFTs and uses backplane technology, the AMOLED display quality is much superior to that of OLEDs. Compared to OLED panels, AMOLED screens are far more flexible. As a result, they are substantially more expensive than OLED displays.

Contrast Ratio

A great degree of pixel control is available with the OLED display. Because it can be turned off, it has a better contrast ratio than AMOLED displays and uses less energy. On the other hand, AMOLED refresh rates are quicker than OLEDs. Additionally, they have a fantastic artificial contrast ratio because each pixel transmits light yet uses more power than OLEDs.

Screen Size

Comparatively speaking, OLED screens are substantially slimmer than LCDs. As a result, it offers presentations that are more effective and vibrant. In addition, compared to conventional LCDs, OLED supports enormous display sizes. AMOLEDs lift the restriction on display sizes. It may be incorporated into any display size.

Considering all that has been said thus far, it is important to recognize that the POLED is an OLED display with a plastic substrate. On the other hand, AMOLED is a marketing term for the display technology used by Samsung. As a result, most phone makers that use AMOLED displays are adopting Samsung screens. Additionally, the use of plastic substrate has made all curved display technologies viable.

What Benefits Does OLED Display Offer?

The layers of an OLED display are plastic, organic, thinner, and more flexible. OLEDs are more vivid and luminous than LEDs but are darker and less vibrant than AMOLEDs. Like LCDs, backlighting is not necessary. OLEDs have a restricted range of display sizes but are less expensive to manufacture. OLEDs have around 170 degrees worth of viewing space.

What Benefits Does AMOLED Display Offer?

The AMOLED display can adapt to any screen size without any limitations. Along the screen producing deeper, inky blacks, AMOLED also has a quicker refresh rate. The AMOLED display provides true color contrasts that are more beautiful and bright. Comparatively speaking, an AMOLED display uses more energy than conventional screens.

Which One Is Best?

OLED and AMOLED are two very powerful display technologies. But compared to OLED, AMOLED has several notably superior advantages.


The development of display technology forces device makers to always search for better solutions. OLED and AMOLED are a blessing in disguise, particularly given how much less expensive the finished product is. The tiny screen sectors have yet to utilize OLED with confidence. AMOLED is naturally more costly than OLED. The deterioration of the display screen is the sole cause for concern.
