The Telop III was introduced in 1954, was a refinement of the previous makes. Reduced to a single-channel version of the Telop, the Telop III ...
The limitation of the material the screen is based on allows only a finite amount of full rolls, hence limiting its commercial application as a flexible display.

Many overhead projectors are used with a flat-panel LCD which, when used this way, is referred to as a spatial light modulator or SLM.
