How to Know if the Mobile Has a Good screen and Tips Before Huying

Without a doubt, the screen is the most important element of our mobile, more than anything because without a screen there is no mobile. All the content, calls, messages, movies or photos that we take, will be shown by the panel of our smartphone with greater or lesser efficiency. Today we wanted to take a look at the most important aspects that we will have to take into account and look at in detail, to see if our mobile have a good screen, or take it into account before changing the model.

We live in the era of multimedia content and where cameras are more numerous and with more megapixels than ever. In addition, mobile games increasingly compete with console games for quality and number of players. It is therefore very important that the panel of our mobile has specific attributes, reaching a minimum standard in some aspects. There is no specific technical section with which we can qualify a mobile as the best, but the combination of several of them.

What has a good screen

Screen size and types

Ensuring a correct display of multimedia content requires a screen size that does not exceed 6 inches. What seemed huge to us a few years ago is now too small. Remember that bets in the mid and high range from 6 inches are almost mandatory. In addition, brands such as Samsung with its Galaxy S20 Ultra, want to set a trend reaching 6.9 inches. A midway size and ideal for this purpose, it should be around 6.5 inches.

LCD screens

They are the cheapest to manufacture The initials, LCD, come from the words Liquid Crystal Display, so we are talking about a liquid crystal. We find two types of LCD screens, IPS and TFT based on the same technology. In this case, the pixels are in charge of modifying a light source that reaches them to show the different colors. They are less bright panels and sometimes offer too muted tones.

OLED screens

It is present in the vast majority of high-end devices. Its light source is diodes, small devices that generate light, and that give color to each of the pixels. It is a very technology when granting pure blacks. In addition, it turns off the pixels that do not need to be in use, so we can save battery life.

AMOLED

In this case each pixel will be illuminated only when electronically activated. Its technology is “active-matrix organic light-emitting diode” This OLED-based display manufacturing technology, but it does not show the pure black tones of the OLED panels.

P-OLED

Screens with this technology manage to be thinner and more moldable. Its technology is inherited from traditional OLED panels.

Refresh rate

At this point in 2020, there is no doubt that the phones that boast the best screen have a refresh rate of at least 90 Hz, reaching 120 Hz in some cases . This attribute measures the number of images the device can display per second. It is measured in Hertz (Hz) because it is a refresh rate.

This causes a feeling of fluidity and screen performance, very noticeable when we surf the Internet or play a game that shows many pixels on the screen at the same time. Therefore, having this attribute on our mobile or taking it into account when buying it, will put us on the track of what a terminal with a good screen is.

Resolution

Resolution is a controversial point in the world of mobile telephony. Many experts continue to insist that the sizes of our mobiles are not large enough for our eyes to appreciate the high resolution that the most powerful terminals on the market sometimes show . Currently we can find various types of screen resolution. Its difference is usually determined by the price of the device, that is, the higher the cost and range, the higher the resolution.

Keep in mind that a higher resolution does not have to imply a better visualization in all cases. But what is certain is that it involves a higher energy expenditure. Hence, the terminal must balance this point with a battery to match. It is for this reason that the mobiles with the highest resolution on the market allow it to be reduced manually in order to achieve greater autonomy.

The resolutions that we can find on mobile phones are as follows. Keep in mind, that the first and lowest, we only find them already in those feature phones or basic terminals, which in some cases can have WhatsApp and other applications, to make them more attractive.

  • QVGA : 240 × 320 pixels
  • WQVGA : 240 × 400 pixels
  • HVGA : 320 × 480 pixels
  • WVGA : 480 × 800 pixels
  • qHD : 540 × 960 pixels
  • HD : 720 × 1280 pixels
  • FullHD : 1080 × 1920 pixels
  • QHD : 1440 x 2560 pixels
  • 4K: 1644 x 3840 pixels

Frame display ratio

Mobile phone screens have undergone a spectacular aesthetic change in the last two years. There is no doubt that a more stylish and attractive mobile is the one that offers a larger piece of screen and fewer side frames. In this way, manufacturers usually show off by showing the percentage. This percentage represents the amount of screen that can be seen on the front, which in the most current mobiles, including the mid-range and of course the high-end, should exceed 90%.

Modify attributes

It is an aspect that remains in the background, but that is becoming increasingly important. If our mobile allows us to modify the attributes of the screen, we will be in front of a device that will be able to provide us with a more precise visualization that we want to have. As with our television, it is important to have the power to touch the brightness, quality, contrast or tone of our mobile screen. This capacity was reserved until recently for high-end mobiles, but the mid-range fighter has long since added this possibility to its terminals.

Points Per Inch (PPP)

This is another value that has an important influence on the quality of the screen of our smartphone. Many times we find the initials ppp or ppi next to the resolution of our mobile and depending on whether they are expressed in English or in Spanish. Thus “ppp” refers to “dots per inch”, “dpi” in English “dot per inch” and “ppi” in English “pixels per inch”, although they all have the same meaning.

The “dpi” details the number of dots that fit on one square inch of screen. This means that if, for example, our mobile phone has 480 dpi, it means that 480 dots are “painted” for each inch high and wide. In this way, the higher the “dpi” value of a screen, it should offer greater definition and therefore image quality. Science has repeatedly claimed that the limit of the human eye to distinguish dots per inch is around 530 dpi.

Screen protection

A good screen is also a protected screen. We must take into account that it has been covered with a plastic of recognized prestige such as Gorilla Glass. In addition, the terminal may have some degree of IP protection. This point is also good, since in case of screen breakage, it could offer better resistance to the entrance of water or humidity.

Key technologies

In recent times, the differentiation between manufacturers means that incorporating any technology can be key. In this case we will have to take into account two of the most important. The first is the so-called HDR (High Dinamic Range) . Recall that the HDR (High Dynamic Range) Mode technology allows you to improve the contrast and detail of the image, by unifying the information of several images and combining them into a final image. This makes dark tones, for example, when we consume multimedia content.

The fingerprint sensor on the screen is another technology that will incorporate the best panels on the market. It does not have a direct influence on its quality, but it is true that it is considered for high-end mobiles and increasingly, premium mid-range mobiles. This sensor eliminates the rear or side fingerprint, so that just by touching the screen we can access the secure unlock of our terminal.

All-screen

It is one of the biggest battles in the industry. Offering a screen without hindrance is possible, but it is not as present as one would like. Manufacturers launch to a greater extent, terminals with notch or holes in the screen, which serve to house the front sensor. However, the true all-screen experience, and therefore a better screen, has to do with those phones that have a pop-up front sensor. Furthermore, it is expected that in the near future
