IPhone 1 1 is a 6. 1 inch screen with a resolution of 1792 x 828, while the pixel per inch is only 326PPI.

IPhone 8 Plus has a 5.5-inch screen with a resolution of 1920 x 108, and 40 1PPI pixels per inch.

By comparison, we can find that the screen of iPhone 8 Plus is smaller than that of iPhone 1 1, but the resolution is higher, so the pixel per inch is higher, so the display effect is more delicate.

The contrast of iPhone 1 1 is 1400: 1, but it is higher than that of iPhone 8 Plus. But on the LCD screen, such a small gap is almost imperceptible to the naked eye.

IPhone 1 1 cancels the 3D touch screen pressure, which is the function of "three-point touch". Although 3D Touch is not used by many people, it is still very practical when playing games.

Although the difference in pixels per inch may be imperceptible to most users, and the paper screen size of iPhone 1 1 is larger, the screen size is calculated diagonally. Because of "bangs", the visible area of iPhone 1 1 is not much more than that of iPhone 8 Plus. Moreover, the existence of bangs affects the experience of videos and games.

IPhone 1 1 is not as good as iPhone 8 Plus in screen display effect.
