Everything You Want to Know About AMOLED screen.

Welcome to Blackview blog.

AMOLED (active-matrix organic light-emitting diode) is a type of display technology that uses organic light-emitting diodes (OLEDs) to produce images. AMOLED displays are known for their vibrant colors, deep blacks, and wide viewing angles. They are also thinner and lighter than traditional LCD displays.

Here is a full guide about AMOLED screens, including their benefits, drawbacks, and how they compare to other display technologies:


How do AMOLED screens work?


AMOLED screens work by using organic light-emitting diodes (OLEDs) to produce images. OLEDs are made up of a layer of organic material sandwiched between two electrodes. When an electric current is applied to the electrodes, the organic material emits light. The amount of light emitted by the OLED is controlled by the amount of current applied.

Each pixel on an AMOLED screen is made up of three subpixels: red, green, and blue. When these subpixels are activated, they emit light in their respective colors. The combination of these three colors creates the image on the screen.

AMOLED screens are different from traditional LCD screens in that they do not require a backlight. This makes them thinner and more power efficient. AMOLED screens also have a wider viewing angle and better contrast ratio than LCD screens.


Benefits of AMOLED screens


  • Vibrant colors: AMOLED screens produce incredibly vibrant colors that are often more lifelike than those on LCD displays. This is because OLEDs can emit their own light, so each pixel can be individually controlled to produce the exact color desired.
  • Deep blacks: AMOLED screens can produce true blacks by turning off individual pixels. This results in a much higher contrast ratio than LCD displays, which can only produce dark grays when pixels are turned off.
  • Wide viewing angles: AMOLED screens have wide viewing angles, so images look great from almost any angle. This is not always the case with LCD displays, which can sometimes have color shifting or brightness problems when viewed from off-angle.
  • Thinner and lighter: AMOLED screens are thinner and lighter than traditional LCD displays. This makes them ideal for use in mobile devices, such as smartphones and tablets.


Drawbacks of AMOLED screens


  • Burn-in: AMOLED screens are susceptible to burn-in, which is a permanent image retention that can occur when a static image is displayed on the screen for a long period of time. This is not a common problem, but it is something to be aware of if you are considering an AMOLED display.
  • Price: AMOLED screens are typically more expensive than traditional LCD displays. This is because the technology is more complex and requires more expensive components.
  • Brightness: AMOLED screens can sometimes be dimmer than LCD displays, especially in direct sunlight. This is because OLEDs are not as efficient at producing light as LCDs.



How AMOLED screens compare to other display technologies


AMOLED screens are often compared to LCD (liquid crystal display) screens. LCD screens are the most common type of display technology and they are typically less expensive than AMOLED screens. However, LCD screens do not offer the same level of contrast, color accuracy, or viewing angles as AMOLED screens.

Another type of display technology that is sometimes compared to AMOLED screens is IPS (in-plane switching) LCD. IPS LCD screens offer better viewing angles than traditional LCD screens, but they do not offer the same level of contrast or color accuracy as AMOLED screens.

Overall, AMOLED screens offer a number of advantages over other display technologies, including vibrant colors, deep blacks, wide viewing angles, and thinner and lighter designs. However, they are also more expensive and can be susceptible to burn-in. If you are looking for a display with the best possible image quality, then an AMOLED screen is a great option. However, if you are on a budget or are concerned about burn-in, then you may want to consider an LCD screen instead.


Which AMOLED screen is right for you?


There are a number of different AMOLED screens on the market, so it can be difficult to decide which one is right for you. Here are a few factors to consider when making your decision:

  • Price: AMOLED screens can range in price from a few hundred dollars to several thousand dollars. It is important to set a budget before you start shopping so that you do not overspend.
  • Size: AMOLED screens are available in a variety of sizes, from small smartwatch screens to smartphone screens, to large television screens. Choose a size that is appropriate for the device you will be using the screen on.
  • Resolution: AMOLED screens have different resolutions, which determines the number of pixels on the screen. A higher resolution screen will produce sharper images.
  • Features: Some AMOLED screens have additional features, such as curved displays or HDR support. Consider which features are important to you before making your decision.
