Why do screens need to fold at all? In folded mode an edge to edge screen is enough and in unfolded mode two more of those can combine to make one large display. It’s the same as those led walls you see in places, made of edgeless panels that slot in next to each other. Curving the pixels is stupid.
Or just save it to one of those 16tb hard drives we have nowadays. They can’t remove it from your own collection either way.
