What Is Super-AMOLED (S-AMOLED)?

Definition of Super AMOLED

S-AMOLED (Super Active Matrix Organic Light Emitting Diode) is a marketing term referring to the display technology used in various electronic devices. The “super” in its name sets it apart from older, less advanced versions (OLED and AMOLED).

S-AMOLED can also be called as Superamorphous Organic Light Emitting Diodeeither Super Amorphous OLED Because it uses amorphous silicon technology.

Introduction to OLED and AMOLED

Displays using organic light-emitting diodes (OLEDs) contain organic materials that emit light when they come into electrical contact. The active matrix aspect of AMOLED sets it apart from OLED. So AMOLED is a display technology that includes not only a way to display light, but also a way to sense touch (the “active matrix” part). While it’s true that this approach is also part of AMOLED displays, Super AMOLED displays are another story.

Below is a brief rundown of some of the pros and cons of AMOLED displays.

benefit

  • Wide viewing angle

  • Compatibility with multiple colors.

  • The black rendering is great.

  • Long battery life when using dark colors

shortcoming

  • oversaturated images

  • Reduced battery life when displaying vivid colors

AMOLED displays are known for being able to reproduce deep blacks when needed, which is a huge advantage on any display, and you’ll notice this right away compared to standard IPS (In-Plane Switching) LCDs (Liquid Crystal Displays). ). The benefits are obvious when watching a movie or viewing an image that is supposed to contain “true” black.

AMOLED technology consists of a layer behind an OLED panel that provides light to each pixel, rather than using a backlight like LCD displays do. Because each pixel can be colored as desired, the pixel can be dimmed or turned off for true black, rather than the pixel having no light (as with LCD).

This also means that AMOLED screens are very good at displaying multiple colors; the contrast with white is infinite (because black is absolutely black). On the other hand, this amazing ability makes it easy for images to become overly vibrant or oversaturated.

Super AMOLED and AMOLED

AMOLED and Super-AMOLED are not only similar in name but also in function. In fact, Super-AMOLED is almost identical to AMOLED, but it is this aspect that is different.

The two technologies are similar in that the devices using them can include light sensors and touch sensors so that the screen can be read and manipulated. However, the touch-sensing layer (called the digitizer or capacitive touchscreen layer) is embedded directly into the screen of a Super-AMOLED display, where it is a completely separate layer. optimal Screen in AMOLED screen.

This may not seem like a big difference, but because of the way the layers are designed, Super-AMOLED displays have a number of advantages over AMOLED displays:

  • The device could be thinner because the screen and touch technology are on the same layer.
  • Higher contrast, coupled with no air gap between the digitizer and the actual screen, makes for a sharper, more vivid display.
  • Less power needs to be supplied to a Super-AMOLED display because it doesn’t generate as much heat as older display technologies. This is partly due to the fact that the pixels are actually off, so they don’t emit light or consume power when rendering black.
  • The screen is more sensitive to touch.
  • Since there are not as many layers, light reflections are reduced, making it easier to read outdoors in bright light.
  • Higher refresh rates help speed up response times.

However, the technology behind the manufacture of Super-AMOLED displays is more expensive. As with most technologies, this is likely to change as more manufacturers integrate AMOLED into their TVs, smartphones and other devices.

Here are some other disadvantages of AMOLED technology:

  • Organic materials eventually die, which is why AMOLED displays degrade faster than LEDs and LCDs. To make matters worse, the materials used to create the various colors have variable lifetimes, with noticeable differences in overall uniformity as the colors fade (for example, blue OLED films don’t last as long as red or green).
  • AMOLED is at risk of burn-in due to uneven pixel usage. The effect becomes more complex as blue fades away and red and green take over, leaving an imprint over time. That said, this issue doesn’t affect monitors with higher pixels per inch.

Types of Super-AMOLED Displays

Some manufacturers have additional terms for Super-AMOLED displays with certain features on their devices.

For example, HD Super-AMOLED is Samsung’s description of a Super-AMOLED display with a high-definition resolution of 1280×720 or higher. Another example is Motorola’s Super-AMOLED Advanced, which refers to brighter, higher-resolution displays than Super-AMOLED displays. These screens use a technology called PenTile to sharpen pixels. Others include Super-AMOLED Plus, HD Super-AMOLED Plus, Full HD Super-AMOLED and Quad HD Super-AMOLED.

Frequently Asked Questions

  • What is the difference between Super-AMOLED and Dynamic-AMOLED displays?

    The Dynamic-AMOLED display is a Super-AMOLED display that also supports HDR10+, providing cinema-quality color and contrast. Dynamic-AMOLED displays are also certified for eye comfort by TUV Rheinland, which means they emit less blue light than OLED displays.

  • What is the difference between Super-AMOLED and Retina displays?

    Unlike Super-AMOLED displays, which use LEDs, Retina displays use LCDs. This type of display allows higher resolution video than conventional AMOLED, but AMOLED displays offer excellent contrast.

  • What’s the difference between Gorilla Glass and Super AMOLED?

    Gorilla Glass is a transparent cover for AMOLED screens. Gorilla Glass does not display images; its function is purely protective.

  • Which is better, Super LCD or Super AMOLED?

    It’s a matter of personal preference. When comparing Super-AMOLED and Super LCD (IPS-LCD), the former can display a wider range of colors. On the other hand, Super LCD offers a sharper image and is more suitable for outdoor viewing.

What Is Super-AMOLED (S-AMOLED)?

Definition of Super-AMOLED

S-AMOLED (super-active-matrix organic light-emitting diode) is a marketing term that refers to a display technology used in a variety of electronic devices. The “super” in its name distinguishes it from its older, less advanced versions (OLED and AMOLED).

S-AMOLED might also go by the name super amorphous organic light-emitting diode, or super amorphous OLED because it uses amorphous silicon technology.

Displays using organic light-emitting diodes (OLED) incorporate organic materials that light up when in contact with electricity. The active-matrix aspect of AMOLED sets it apart from OLED. AMOLED, then, is a kind of screen technology that includes not only a way to display light but also a method to detect touch (the “active-matrix” part). While it’s true that this method is a part of AMOLED displays as well, super-AMOLEDs are slightly different.

Here’s a quick summary of some pros and cons of AMOLED displays.

Pros

Wide viewing angles

Support for a large range of color

Great display of black

Long battery life if using darker colors

Cons

Oversaturated images

Shortened battery life when displaying vibrant colors

AMOLED displays are known for being able to render a deep black color when needed, a huge plus on any display and something you’ll notice right away when comparing with your standard IPS​ (in-plane switching) LCD (liquid crystal display). The benefit is obvious when watching a movie or viewing a picture that’s supposed to contain ‘true’ black.

AMOLED technology includes a layer behind the OLED panel that gives light to each pixel instead of using a backlight as LCD displays do. Because each pixel can be colored on an as-needed basis, pixels can be dimmed or turned off to make a true black instead of the pixels being blocked from receiving light (as with LCD).

This also means that AMOLED screens are great for displaying a huge range of color; the contrast against whites is infinite (because blacks are absolute black). On the other hand, this amazing ability makes it easier for images to be too vibrant or oversaturated.

Super-AMOLED vs. AMOLED

AMOLED is similar to Super-AMOLED in not only name but also in function. In reality, Super-AMOLED is identical to AMOLED in all ways but one, but it’s that one way that makes all the difference.

The two technologies are the same in that devices using them can incorporate light and touch sensors so that the screen can be read and manipulated. The layer that detects touch (called the digitizer or capacitive touchscreen layer), however, is embedded directly into the screen in Super-AMOLED displays, while it’s an entirely separate layer on top of the screen in AMOLED displays.

This might not seem like a major difference, but Super-AMOLED displays carry many benefits over AMOLED displays because of the way these layers are designed:

The device can be thinner because the technologies for display and touch are on the same layer.
Higher contrast, plus the lack of an air gap between the digitizer and the actual screen, yield a crisper, more vivid display.
Less power needs to be supplied to a Super-AMOLED screen because it doesn’t generate as much heat as older screen technologies. This is due, in part, to the fact that pixels are actually turned off and therefore not emitting light/using power when displaying black. 
The screen is more sensitive to touch.
Light reflection is reduced because there aren’t as many layers, which makes reading outdoors in bright light easier.
A higher refresh rate helps speed up the response time.

Manufacturing the technology behind Super-AMOLED displays is more expensive, however. Like most technology, this is likely to change as more manufacturers incorporate AMOLED into their TVs, smartphones, and other devices.

Here are some other disadvantages of AMOLED technology:

Organic materials eventually die, so AMOLED displays degrade faster than LED and LCD. Even worse, the materials used to create the individual colors have varying life spans, causing a noticeable difference in overall uniformity as the colors fade (e.g., blue OLED films don’t last as long as red or green).
Screen burn-in is a risk with AMOLED because of the non-uniform use of pixels. This effect is compounded as blue colors die out and leave red and green colors to take up the slack, leaving an imprint over time. That said, this issue doesn’t affect displays with high numbers of pixels per inch.
Types of Super-AMOLED Displays

Some manufacturers have additional terms for Super-AMOLED displays equipped with specific features in their devices.

For example, HD Super-AMOLED is Samsung’s description of a Super-AMOLED display with a high-definition resolution of 1280×720 or greater. Another is Motorola’s Super-AMOLED Advanced, which refers to displays that are brighter and of a higher resolution than Super-AMOLED screens. These displays use a technology called PenTile to sharpen the pixels. Others include Super-AMOLED Plus, HD Super-AMOLED Plus, Full HD Super-AMOLED, and Quad HD Super-AMOLED.
