Among the items that must be observed when choosing a smartphone, the quality of the screen is an essential factor. Yes, because it is through it that you will see your favorite images, videos, series, and movies and if the display is not good, the image quality will be affected.
At present, each manufacturer has a type of technology used in their displays. But do you know what each acronym used to define the displays means and which one is the right one? See below what it is, as well as the differences of the IPS, AMOLED, and Super AMOLED screens.
The In-Plane Switching (IPS) technology used in smartphones such as Lenovo Vibe K5 and Moto G4 is a variation of LCD technology, which means Liquid Crystal Display or Liquid Crystal Display. The difference between the two lies in the alignment of the liquid crystals. In the case of IPS technology, they are horizontally aligned rather than the traditional vertical alignment.
On IPS screens, due to the formation of crystals that are closer to the surface of the screen, the angle of view improves and color reproduction becomes more accurate. One can say that IPS is a technology applied on the LCD to improve the response time in the exchange of the displayed image and to potentiate the variation from one pixel to the other.
- Advantages – The advantage of the IPS screen is its durability since the system of the LCD screens is simplified. Basically, the LCD is a light filter formed by pixels. Each small dot filters the backlight to project the colors on the screen of the device and finally form the images. Thanks to the way each pixel works, there is a greater precision in the colors produced.
- Disadvantages – Screens with IPS technology consume more battery power than their competitors, as the imaging process requires a constant back-light for a color to be generated. On the LCD screen, the crystals become transparent or opaque to let light pass through the pixels. This light stays on all the time. In the case of black, the crystals never turn completely black and more opaque, since the backlight remains on. This is why the black on the AMOLED screens is more intense because the organic diodes are off, that is, you have the complete absence of light.
AMOLED technology is based on OLED. The acronym comes from the name Active-Matrix Organic Light-Emitting Diode or in Portuguese, Matrix-Active of Emission of Light Organic by Diodes. Unlike the LCD, instead of each pixel being a filter, they are the light emitters themselves. Thus, through the game between the red, green and blue colors emitted by each point of the screen, it is possible to create the white and the millions of colors necessary to form the images in the display of the device.
- Advantages – The economy is one of the main advantages of the AMOLED screen. The battery has a reduction of consumption, mainly in black backgrounds, since the pixels are erased and are not fed. In addition, you can build thinner and lighter displays as there are fewer layers to create the images. More vivid colors is another favorable point.
- Disadvantages – Durability of organic LEDs is lower than the competitor, although new technologies have considerably increased their life span.
The Super AMOLED screens are a commercial creation of Samsung, which improved the technology used in the AMOLED screens.
Basically, what the South Korean company did was add a touch-sensitive layer inside the AMOLED screen itself. In this way she has removed the touchscreen glass that the LCD and AMOLED screens have. The result is even thinner, lighter and more sensitive screens.
What is the best?
What makes each of them the best choice is the purpose for which the user wishes to make use of it. If you are looking for sharpness of images and content with good colors but not so intense, IPS technology will please. Now if the goal is to have a vivid color display and a reduction in battery consumption, the AMOLED and Super AMOLED screens are the best choice.
