Everything you need to know about your phone screen when buying.

Often modern gadgets quickly deteriorate and problems with the device's screen are not uncommon. And buyers question whether it is worth paying a fabulous sum for a large screen and whether it is really necessary. Not everyone understands what a good screen should be and how to choose it correctly.

Screen characteristics

Several factors affect the selection of a suitable screen. The main ones are resolution and panel type. Each of the parameters is divided into separate sub-items. To evaluate the screen in mobile, you need to be able to at least partially navigate in the main characteristics.

Resolution options:

  • HD - high definition. Contains 1280 * 720 pixels. The higher their density, the clearer the picture will be. There is an opinion of the developers that the optimal size is 300 dpi.
  • Full HD - 1920 * 1080 pixels. So, with a diagonal of 5 inches, the pixel density will be 440 ppi (pixels per inch). But if the screen is 5.5, the density will already be 400 ppi.
  • QHD is 4 times the size of regular HD and is 2560 * 1440 pixels in size.
  • Ultra HD has dimensions of 3860 * 2160 pixels.

The next factor is the type of panel. They can be of the following types:

  • LCD;
  • OLED;
  • Super AMOLED;
  • TFT;
  • IPS;
  • TFT LCD.

LCD (stands for Licuid Crystal Display). Designed from backlit liquid crystals. They are sold at an affordable price, which makes them profitable for manufacturers. They work in bright sun, but have inaccurate color reproduction.

TFT displays are thin film transistors. Attractively low cost and high quality compared to conventional LCD.

IPS is an improved version of TFT. The AMOLED type has a decoding, an organic light emitting diode with an active matrix. However, this is just a different technology for producing a thin film screen. Their disadvantage is the quick wear of the diodes and the high frequency of updates.

OLED is an organic material that allows light to pass through. These screens only light up when current is applied to a single pixel. This suggests that such screens consume less energy when reflecting dark details. They give a clear image compared to LCD screens. Super AMOLED requires less power and works well in bright light.

More information about the panels can be found in the mobile phone stores. Pay attention to the refresh rate. It shows how many times the image is updated per second. So, at a frequency of 60 Hz, the image will be updated 60 times per second. The faster the update goes, the smoother the picture of the moving object looks. The higher the frequency, the less motion blur will be. This is necessary for games and quick scrolling of pages on the web.

How to determine the optimal screen diagonal and other sizes

Of course, there is no ideal display size. Everyone has their own palm size and everyone chooses the device for themselves. However, you can determine the dimensions that are suitable for yourself.

Determine the size in this way:

  1. The device is taken in the usual way.
  2. Wipe the screen to get rid of prints.
  3. Put your thumb in the corner of the screen that is closer.
  4. Move up diagonally to the far corner. Continue pulling as long as you feel comfortable. If you have to stretch, then the size does not fit. This point needs to be remembered.
  5. Next, take a ruler. Measure the distance between the closely spaced corner and the previously determined point.
  6. The resulting value in mm is divided by 25. This will be the size in inches.

Today, screens that need to be held with two hands are gaining popularity. They are called phablets. This name comes from the English word phablet, which is assembled from the words phone (phone) and tablet (tablet). This device combines the functions of a tablet and a phone.

Along with the pluses, these screens have minuses. Models will not fit into standard jeans or other clothing pockets. After testing these devices, many users did not want to go back to the usual models. During the research, it was also revealed that the thickness and weight of the phone are not important indicators for the purchase.

When choosing a screen, it is worth considering the purposes for which the phone is used. If colors and contrasts are important, choose the AMOLED model, if the lifestyle is more active, then the LCD screen. When the phone is used mainly in the evening, you should refuse to purchase an LCD display.
