Earlier quoted context omitted.
As someone from and in North America, we don't usually refer to multi-layered thin glass as "thick" glass, we call it "double pane" or something similar. Particularly since it's much lighter than an actual, single glass pane of equal thickness, which is the point here: the weight wouldn't be an issue, and even if it was, the screen is far, far heavier than better insulation.
It seems your a bit confused? A solid pane literally equal in thickness with a typical double pane assembly would practically only ever be used for much higher end products, like armored cars and so on. No one serious would ever consider it for normal commercial coolers. And the vast majority as of 2023 already use double paned glass, so comparing this at all seems irrelevant. You don't need to have expert knowledge…
Recall that the topic was your suggestion that "It's not feasible to make glass doors on coolers much thicker", which given this new information, doesn't seem true. Indeed, these screens are a second layer of glass stuck on the existing glass cooler door, with electronics in between. That's heavier than the same thing with air in between.
