Cool Text Wallpapers

For split-flap displays, the characters or words are pre-printed, and for nixie tubes the shapes are also pre-formed.

In any case, the display elements are controlled by electronics which activate them in the correct physical and temporal sequence to show the desired information.

Text displays are used in everything from clocks (clock radios, wristwatches) to variable-message signs (departure boards, intelligent transportation systems), because up until the late 2000s, they were (and in many cases still are) the least expensive for their purpose.

LED text displays refer to types that are specialized and limited to display of alpha-numeric characters.
