I used to have one of those. It’s was definitely neat, and managed to survive a while, but I don’t think it’s a good idea. The biggest issue with something like this is that it adds more moving parts, which in turn increases wear and tear. For the screen to move, you’d need to either use a ribbon cable, or have weird contact points that only work in certain positions. Both of which aren’t great. Ribbon cables flex for a bit, but eventually tear, meaning no screen. The goofy contacts is slightly better, but eventually the sliding mechanism may go out of whack and now it isn’t making contact correctly.
