What are the differences between segment code LCD screens and dot matrix LCD screens?

Although both segment code LCD screens and dot matrix LCD screens are display devices, there are some differences between these two types of LCD screens.
LCD liquid crystal screens have been widely used in various industries, resulting in a variety of types, mainly including: character dot matrix LCD screens, graphic dot matrix LCD screens, broken code LCD screens (segment code LCD screens), OLED LCD screens, and so on. These LCD screens are used to display information on the device, and each type of LCD screen has its own differences. So what is the difference between a dot matrix screen and an LCD screen, and what is the difference between a segment code screen and a dot matrix screen?
