If you took the LCD screen from a tablet. Segmented it into equally sized rectangles, and then added connection ports on the sides of each rectangle. Could you then separate and stack the rectangles on top of eachother to save space? And then fold it back out to create a tablet-sized screen again.
(Crude drawing of what I mean)
I saw “telescopic LCD” and thought of using those screens for telescopes. Am disappoint it’s just folding LCD. I don’t think it’s feasible with those, specifically, due to their construction of film layer + liquid crystal + other film layer + backlight. Unless you’re ok with essentially 4 separate smaller screens
