Resolution, also known as resolution and resolution, can be classified from two directions: display resolution and image resolution.
Display resolution (screen resolution) is the precision of the screen image, which refers to the number of pixels that the display can display. Because the dots, lines and surfaces on the screen are all composed of pixels, the more pixels the display can display, the more fine the picture will be, and the more information can be displayed in the same screen area, so the resolution is one of the most important performance indicators. The whole image can be imagined as a large chessboard, and the resolution is expressed by the number of intersections of all longitudes and latitudes. When the display resolution is fixed, the smaller the display screen, the clearer the image will be. On the contrary, when the size of the display screen is fixed, the higher the display resolution, the clearer the image will be.
