Scoreboard

A display panel is usually mounted in the public panel that allows viewing current, changing information from a greater distance.

Species

Basically, one can distinguish between manual and automatic scoreboards. The former can be changed, for example, chalk and a sponge or by the exchange of panels, the latter will change automatically and usually by computer control.

In automatic scoreboards can distinguish between mechanical and electronic boards. Mechanical panels are usually fall leaf displays in which mechanically all the display options can be scrolled through 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 modern electronic displays require no mechanical moving parts, LEDs will be used mostly as pixels or large liquid crystal display with backlight. However, it is also big screens are used. These screens are technically mostly composed of several smaller screens.

In fall leaf displays and many liquid crystal displays (which are not constructed on a matrix of individual pixels ), only certain predetermined characters are displayed; Scripture, however, is easier to read than the often crude representation by image points (pixels).
