Hispider tells you the screen size and resolution of phone
Nowadays, with the development of comprehensive screen, the size of mobile phone screen is getting larger and larger, a few years ago, 6 inches is a large screen phone, and now, less than 6 inches of mobile phones are very few. However, with the increase in the size of mobile phones, especially the increase of 18:9 and other proportion mobile phones, we find that the "size" of the mobile phone is not large, or even smaller than the smaller size of the mobile phone, the most obvious example is the 5.8 inch iPhone x actually got the hand, not larger than the 5.5 inch iPhone 8 plus.
The reason is that in the past, the measurement standard of mobile phone size has always been the diagonal length, which is OK in the case of the same proportion of mobile phone screens, but when there are different proportion screen screens such as 16:9 and 18:9 screens, even in the case of the same diagonal length, the screen area is different. So the way we're going to calculate the screen size for you today is not the diagonal length, but the actual area of the phone screen, which is the length of the phone screen multiplied by the width.
About pixel density of mobile phones:
The screen resolution calculation method proposed by Apple from iphone4 is as follows:
PPI is the number of pixels per inch. pixels per inch indicates the number of pixels per inch. In fact, the calculation method is very simple, calculate the number of diagonal pixels with the number of long and high pixels, and then divide the number of diagonal pixels by the screen size is PPI, the formula is expressed as PPI=√ (X^2+Y^2)/Z (X: the number of length pixels; Y: number of width pixels; Z: Screen size). Calculated the PPI of millet phone 2 screen, 4.3 inches, resolution 1280*720, PPI=√(1280^2+720^2)/4.3=341.5359...... Material 342
The area of the screen calculated by diagonal is not reliable, so the PPI obtained by dividing the number of pixels by the diagonal size cannot truly reflect the real resolution of the screen. Therefore, the pixel density of the screen calculated in this paper adopts the number of pixels of the screen divided by the calculated area, and only the first three digits of the result are taken because the resulting number is longer. This calculation method can better reflect the fine screen. In order to distinguish it from PPI, I named it PPA (pixels per area), which is the number of pixels per unit area.
At the same time, we need to take into account that Amoled screens are arranged in pentile, so the pixel density is 2/3 of the ordinary, so the mobile phone PPA of the Amoled screen in the following example will be multiplied by 2/3. Finally mark PPA. At the same time, Huawei's Sharp White Magic screen due to the use of white pixels, while sharing the reason of blue pixels, the resolution is 91% of the actual pixel density, so its PPA will also be increased by 91% on the original basis.
Let's calculate the screen area of several iPhone models
The iPhone se is 4 inches, has a resolution of 1136 x 640,326 PPI, an area of 6.842 and a PPA pixel density of 106
The iPhone 8 is 4.7 inches, has a resolution of 1334 x 750,326 PPI, an area of 9.436, and a PPA pixel density of 106
The iPhone 8 plus is 5.5 inches, has a resolution of 1920 x1080, 401ppi, an area of 12.925, and a PPA pixel density of 160
The iPhone x is 5.8 inches, 2436 x 1125 resolution,458ppi, 12.633 area, and 144 PPA
The iPhone XR is 6.1 inches, has a resolution of 1792 x 828,326 PPI, an area of 14.168, and a PPA pixel density of 105
The iPhone XS max is 6.5 inches, has a resolution of 2688 x 1242,458 PPI, an area of 16.087 and a PPA of 138
