There is no physical recipient in the brain, because it can't be defined in physical terms.
So far as I can tell, the 'recipient' you're suggesting can't be defined at all. The 'recipient' - us - can quite easily be defined in physical terms: we are the pattern of activity in the brain.
All the brain can do is store and pass information via the cells.
Broadly, yes. Data, actually, but yes.
The recipient of the information is a single entity of awareness which perceives the information in numerous brain cells.
There is no evidence for this independent 'entity', no evidence for any communication coming into the brain from an undetected source, no gap in the information flow through the brain. The recipient of the information is an emergent property of that data flowing.
The pixels on a screen do not perceive themselves - the picture on the screen can only be perceived by an outside observer. To perceive the binary content of many brain cells, you need something other than another group of brain cells.
The pixels on the screen, though, are not the pattern of understanding, they are hand that waves because of the understanding.
The software in the processor that sends that signal to the screen is the correct analogy - it's highly unlikely that any of those software architectures are sufficiently complex to evince the sort of awareness we have as humans, but given the subjectiveness of self-awareness we have no idea if they are the equivalent of plants, or snails, or fish, or simple mammals.
