The resolution of a smartphone is the number of pixels along the horizontal and vertical axes of the screen. The higher the indicator, the larger the number of individual bright points and the clear and detailed appearance.
It is also important to understand that the number of pixels within itself does not determine the final quality of the picture. In addition, it is important to consider the size of the screen and the imaging distance, that is, the intensity of pixels. It is measured in PPI. However, the trick is that the human eye can distinguish pixels with a place of only around 300-400 ppi. If the density is higher, you will not notice a special difference between the screens. Moreover, the higher the PPI value, the more energy the smartphone consumes and the faster it is emptied.
In addition to the density of pixels, the quality of the screen is strongly affected by the color reproduction and accuracy of the pallet. For example, smart phones with Amoled, Super AMOLED, HDR+ colors will be more realistic and accurate.
If you often use a smartphone in the sun or in the dark, the brightness and contrast of the screen is important. In addition, screens with 90, 120, 144 Hz update frequency are smoother than 60 Hz.
Second, the quality of the material where the glass is made. If a premium glass will be better protected from scratches and impacts.
