Adding extra layers of glass increases the thickness and weight of the entire glass assembly, which is colloquially what we refer to as glass thickness in North America.
Maybe it's different from where your from?

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.
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 to insist on your own opinions, but presenting amateur knowledge as if it was doesn't help the discussion. I would recommend studying industry publications if your genuinely curious about this field.
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.
