Background

The screen resolution is the number of pixel points in the vertical and horizontal directions and has a unit of px. The screen resolution determines the setting of how much information is displayed on the computer screen, measured in horizontal and vertical pixels. For the same size screen, when the screen resolution is low (e.g., 640x480), there are few pixels displayed on the screen and the size of a single pixel is large. When the screen resolution is high (for example 1600 × 1200), a large number of pixels are displayed on the screen, and the size of a single pixel is small.

The display resolution is the number of pixels displayed on the screen, and the resolution of 160 × 128 means that the number of pixels in the horizontal direction is 160, and the number of pixels in the vertical direction is 128. Under the condition of the same screen size, the higher the resolution ratio is, the finer and finer the display effect is.
