Morphology
The noun phrase is transparently compositional: 'fluorescent' (producing a visible glow when excited by radiation) straightforwardly modifies 'screen' (a display or surface), so a learner who knows both words can infer it is a screen that emits visible light when excited. The adjective+noun pattern is cross-linguistically common; only technical details about coating or specific radiation types are specialized and not required for basic comprehension.
Etymology
The noun fluorescent screen names a screen that 'glows' when hit by invisible rays. Picture a dark panel lighting up to show shapes when X-rays or cathode rays strike it, and you can see why the term means a screen used to make those hidden rays visible.
