Basically, a distinction can be made between manual and automatic display boards. The former can be changed, for example, with chalk and a sponge or by exchanging blackboards, the latter change automatically and usually through computer control.

With automatic scoreboards, a distinction can be made between mechanical and electronic scoreboards . Mechanical panels are usually fall-leaf displays in which all display options can be scrolled through mechanically in one or more display fields, or they consist of bistable display elements , one for each picture element ( pixel ) or each segment of a seven-segment display . The more modern electronic displays do not require any mechanically moving parts; mostly light-emitting diodes are used as pixels or large-area liquid crystal displays with background lighting. However, large screens can also be used. From a technical point of view, these screens are usually composed of several smaller screens.

In the case of fall-leaf displays and many liquid crystal displays (which are not constructed as a matrix of individual pixels), only certain specified characters can be displayed; however, the writing is easier to read than the often coarse representation using image points (pixels).
