The element that we look at the most of our smartphone is the screen, with which we interact at all times, the one that shows us the information, after all, the most important element in our mobiles today. For many people, it is the screen that is responsible for choosing one or the other as a travel companion.
Beyond resolution and size, people are increasingly looking at the technology used in the fight to be the best screen. Next I will explain a little the main characteristics, leaving aside the more complicated technicalities, a bit by way of summary.
Super LCD displays, a simple variation of LCDs
It must be stated that LCD technology is the father of all types of screens other than OLED, either TFT or IPS. The main feature of an LCD screen was basically that it was liquid crystal. The first of this type were TFTs, which had a transistor in each pixel that could be controlled individually.
These types of screens were very cheap to manufacture and offered a relatively good contrast, the problem was the enormous amount of power they needed, something intolerable considering the sizes of screens that are handled today. One of the evolutions of this technology was the Super LCD, known to be on HTC smartphones.
The advantages of this Super LCD are that the energy consumption is lower and the visibility of the screen is better. This is achieved by eliminating the air between the external glass and the rest of the layers of the screen. Of course, this lay in the possibility of making thinner terminals. However, despite going for the fifth generation (HTC 10), energy expenditure is still relatively high.
IPS screens, the most widespread
IPS screens are another evolution of TFT LCD, in this case we are talking about panels that show the truest colors as possible and very good viewing angles. The exception is the color black, since, although as dark as possible, the pixels do light up, something that does not happen in AMOLED panels.
The main problems are that the terminals will have to have a greater thickness, the light leakage that occurs in some cases and the higher energy consumption compared to OLEDs, but as advantages we have the good visibility in direct sunlight, viewing angles and good color rendering.
Today they are IPS LCD panels the most widespread among smartphones for its characteristics and for being cheaper to produce. Retina displays are nothing more than an IPS screen that was baptized with that name by Apple as they were the first to exceed 300 dpi density (although they were invented by IBM in 1998 in reality).
AMOLED screens, Samsung’s hallmark
OLED technology is the only one in this post that does not come from LCDs, and its pixels only light up when electrically activated. The main advantage of these panels is that when it comes to reproducing black, the pixels are deactivated, so they consume less power.
AMOLED screens add a TFT active matrix that regulates brightness with which the pixels are displayed. Another differential characteristic is that the panels are thinner than the IPS, which allows manufacturers to make thinner terminals or put a slightly larger battery (something that would be appreciated):
One of the problems with this technology is that it is more expensive to produce, but on a technical level they are usually less visible in direct sunlight, especially if you dedicate yourself to reproducing dark images. For some, the issue of color saturation is a defect since the images are less real, but that is where the tastes of each enter.
What technology do you think is the best?
In this post we have reviewed, a bit by way of summary, the main characteristics of the most widespread screen technologies in the Android mobile market. TAll of them have a series of advantages and disadvantages that will make you choose one terminal or another on your screen.
Therefore, and given that no technology is objectively better than another, we would like to know what type of screen you prefer and why.
