It's not necessary for a display to have an operating system.
They make fixed-function chips in factories every day that do stuff like convert video signals from one format to another (including formats that LCD panels can deal with).
Like the TFP401. For illustration, here is one on a board, ready to plug into an LCD panel and use for whatever: https://www.adafruit.com/product/2218
It doesn't run an OS. It's barely even programmable, and the programmability it does have relates only to configuring pre-defined hardware functions. It doesn't have an instruction set. It can't add 1+1.
But it can bridge the gap between a consumer device that produces video and a fairly bare LCD panel. It's a very much a single-tasker.
(Do any of the current crop of consumer-oriented televisions and computer monitors use this kind of simple pathway? Most assuredly not, which is the complaint that brought us here to begin with.
But these pathways exist anyway. It's completely possible to to create an entire video display and house it in a nice-looking package, put it in a retail box, and sell it on store shelves without involving an operating system. It's not a technological limitation.)
