Then it's basically a digital wallet right?

No, it wouldn't allow for transactions. It would not have any internet connection or means of communication.
They would have only a chip, solar cell, and display.

But what is the advantage over paper? It sounds like it would be more likely to break with no added benefit.

could generate paper wallet without computer. Why not make it like a card or something difficult to break.

True... but it's a digital cold storage wallet. What makes it a "electronic display paper wallet?" Electronic cold storage wallets are nothing new.

better idea: Make credit card-like devices with ships that have the private key, and devices like credit card machines that can read then for consult(they will be offline), and others for trading(online ones)

And I didn't get the forgot and remember button idea

the private key on the card is printed by the issuer and may be kept by them. You fund in this card may lose. You idea is not secure enough. OP's idea seem to be applicable. The private key is inputted or scanned to this blank device then make the device remember it. If you plan to dump the private key, just forget it and remember new one.

the wallet does not ever "allow" or not allow transactions. It is the fact that you control a private key that has unspent outputs that allows you to make a transaction.

much easier to just have a business card with a public key in a QR code on the back

I just came across some business cards today that fold up and make usb drives...those were pretty cool too

If they were cheap enough, like $1, you could use them just as if they were a piece of paper.
The good thing about it would be that you wouldn't have to use a computer and printer to get your paper wallets.
And could get new wallets once you thought they got compromised.

Then why not use paper in the first place? Also: You don't want to use a photocopier to copy paper wallets. They may have a built in memory and could be accessed externally in order to steal you private key. The same goes with printers, especially network enabled ones!

I was thinking the same it seems you mean a digital wallet. It does seem like a good idea I will admit especially at the right price however how 100% safe could it be if there was one?

I think this could be good to introduce bitcoin to the average Joe.
It would be a paper wallet in a e-ink support and would have just one switch button to forget and remember.
It should be good to make photocopies of them, without any problem.
Maybe we are not that far from having such e-ink supports for massive production of such at a very cheap price.
