Screen types on a Smartphone, which is the best?

When opting for a new mobile device, it is logical to focus attention on the quality of the screen that is offered. And it is that not everything is reduced to the size of the same or the native resolution that it has, but also the type of materials with which it has been made and its impact on the user’s viewing experience.

Currently There are several popular alternatives, from classic LED panels, through OLEDs and up to the AMOLED designations that have spread so much through the high-end terminals on the market. If you are one of those who are not able to appreciate which is which, then we review their main differences:

LCD, OLED and AMOLED display

Dynamic AMOLED

Dynamic AMOLED is the latest standard introduced by the Samsung Galaxy S line

The most common thing to observe in stores, especially among entry-level and mid-range phones is the use of the LCD technology, that is, a set of liquid crystals that are illuminated through a backlight that is divided evenly over the entire surface. From this there is its main point in favor, which is good visibility in direct sunlight.

In recent times, slight changes have appeared in this technology, such as mini-LCD or mini-LED screens that divide the panel lighting into small areas.While in the case of Apple, the term Retina displays stands out, which is actually a trade name for its products that refers to the same type of LCD panels but with a high pixel density.

In turn, a variant emerged from LCDs that corresponds to LED screens. In general they have a similar operation but with a change focused on the backlight system. While the former use cold cathode fluorescent lamps, the latter use a diode or light emitter that helps to consume less energy.

The next leap in quality corresponds to OLED panels, that are not only part of “Premium” series of telephones but also in televisions. Its composition with organic materials has the possibility of emit light independently, being able to turn each of its pixels on and off separately.

In your case the advantage is in showing deeper black tones and highlighting the contrast with respect to the rest of the pixels that are being appreciated on the screen, in addition to greater efficiency in energy consumption compared to LCD panels. The disadvantage? A shorter useful life due to the degradation of its internal components.

To conclude, AMOLED technology has been made popular by brands like Samsung and means a variant of the above with the addition of an active matrix. Its composition is based on two sub-pixel structures, a standard RGB and Pentile RGBG, which adds an extra green pixel to increase its luminosity.

As constant evolution, there are already variants called “Super AMOLED” which adds an additional integrated layer within the screen to recognize touch functions, while more recent calls “Dynamic“Or” Optic “AMOLED have improvements to reduce the sensations of eye fatigue with differences between them in the control software and the calibration used.
