Experts from the analytical company UBI Research have calculated that 122 models of smartphones with OLED screens were released in the first half of the year. If we divide them into groups by screen size, it turns out that 119 models, or 97.5%, had a screen size of 6 to 7 inches. There was only one model with a smaller screen, and two models with a larger screen.
When it comes to resolution with reference to screen size, values in the range of 400-500 pixels per inch are the most common. They are found in 64 models, which is 52.5%. In 48 models, the screens are characterized by a lower density, in 10 models – more. The leader is the Sony Xperia 1 II with a screen density of 643 pixels per inch.
