Some years ago there was this „paperlike kindle“ that was advertised with: „you can read it in bright daylight!“ and then we never heard about this invention again.
Edit: thanks for your input. I think I understand now.

Do you have an old phone? Today’s flagships are very easily readable in daylight. Their potential light output is actually pretty insane.
Also you didn’t hear about that invention again in the same way you don’t hear about tires, toasters, fridges. They are just in use now and aren’t novel. The very technology you mention (e-ink) still exists and is being sold if you want to buy a product that has one for pretty cheap.
