I believe the answer is:

flat-screen television

I'm a little stuck... Click here to teach me more about this clue!

'unit' is the definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?

'transmitting close intensive material essentially' is the wordplay.
I cannot really see how this works, but
'close' could be 'on' (I've seen this in other clues) and 'on' is found within the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
