resolution in the market has two main indicators: 1920x1080, 1366X768. For example, the physical resolution of 1366X768 indicates that its imaging device has 1366X768 pixels. At the same time, pixels are also the basic units of the image. A 1920x1080 resolution image indicates that the image consists of 1920x1080 pixels. Only when the resolution of an image or signal source is exactly the same as the physical resolution of the TV can their pixels be mapped one to one (point-to-point display ),
, there are different things to consider. One is to consider objects that follow interface rules, and the other is to consider instances of specific classes.
The interface is more flexible, and the implementation function is also relatively simple. The specific class can implement the function and provide some additional information.
