AMOLED vs OLED vs LCD Display explained

AMOLED vs OLED vs LCD Display

Besides the processors, one of the many choices you need to make when buying a new mobile device is supported by the type of display. Most manufacturers prefer AMOLED screen. So, what is this new display technology and its advantages and disadvantages? This article explains AMOLED, Super AMOLED, OLED & LCD displays, their characteristics and their differences.

AMOLED vs OLED vs LCD screen

You must have seen an OLED display screen widely used in commercial advertisements, sports venues, stock exchanges, etc. The same technology has become a standard feature of some flagship smartphones and tablets, as well as digital cameras and smart TVs.

There is not much difference between AMOLED and OLED. In fact, AMOLED Display is a variant of the OLED display technology. It is the organic light-emitting diode with active matrix, also known asOLED Active MatrixOLED. A typical AMOLED display consists of a layer of organic materials located between two electrodes, the anode and the cathode, all deposited on a substrate. The organic layers have a thickness of about 100 to 500 nanometers, which is equivalent to 200 times the size of a human hair.

AMOLED and Super AMOLED are display technologies used in mobile devices and televisions. These screens consist of a set of thin electroluminescent layers (light emitting materials in response to the passage of an electric current), organic compounds producing energy and a pixel modulated matrix.

Compared to AMOLED, Super AMOLED can be considered a more advanced version incorporating touch sensors. These touch sensors are built into the screen itself, instead of having them at the top of the screen. Plus, Super AMOLED features a 20% brighter screen, 20% lower power consumption and 80% reduced sun reflection. AMOLED, on the other hand, has poor visibility on the outside (in the presence of direct sunlight)

The evolution of cathode ray tube technology has led to the migration to LCD technology or liquid crystal display (LCD) technology. The main difference between LCD screens and OLED or AMOLED displays is that LCD The screens use a background light to display the image, a A MOLED the screen has its own light source. Each panel (screen) AMOLED is composed of a number of pixels. Each pixel represents a minute illumination area on a display screen, one of many from which an image is composed. Each pixel emits its own "background light" and thus renders its light and color independently when it is electrically activated. A Thin Film Transistor (TFT) layer helps control the light emitted by OLED pixels.

Advantages and disadvantages of the AMOLED screen

Although there are many advantages to using AMOLED displays, some disadvantages are also inherent. Here is a preview!


  • AMOLED displays have a faster response time than LEDs and LCDs. No backlighting is required. This makes the body slim compared to LCD screens.
  • AMOLED displays provide a higher artificial contrast ratio in dark conditions and a better viewing angle than LCD screens.


  • The production cost of an AMOLED screen is high. In addition, the technology needed to develop AMOLED panels is very expensive.
  • An AMOLED display has very low visibility outdoors. For example, it is difficult to visualize anything on an AMOLED panel in direct sunlight as there is no backlight and reduced maximum brightness.
  • A large variation in the life of each organic material specific to color is observed. Red and green OLED films have a longer life than blue OLED films. This variation over a given period results in color offsets when some pixels fade faster than other pixels.

Advantages and disadvantages of LCD screens

LCD technology continues to evolve and change.


  • The biggest advantage of the LCD is that it is easy to eliminate.
  • It has a low rate of flicker
  • Can be used in battery-powered electronics
  • It is not affected by magnetic fields (a major disadvantage of CRTs)


  • When looking at different angles, color and contrast appear inconsistent
  • Due to backlighting, images may appear flat.
  • loss of contrast in high temperature environments
  • consumes a lot of electricity and produces a lot of heat
