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.

E-ink is great if you have an external light source, but it’s not good for any color or motion, let alone video playback or games, it’s generally a bad display if you’re NOT using it as an electronic book. It’s just a bad fit for the things we expect our phones to do.
In short, if we want accurate colors, fast changes to the picture (like video or even scrolling down a page), and also want to be able to use the display in the dark, we need to produce our own light behind the screen, or with newer OLEDs, directly in the screen itself.
Unfortunately, the sun is insanely bright and we have not developed technology that would lets us produce a backlight or self-lighted display that rivals the sun… we probably never will… at least not on battery power in a tiny phone.
This is a video reviewing a product that uses sunlight instead of an internal light, so it is readable in the sun. Very cool tech, but they discuss in the video why it’s not that versatile or good for regular use: [https://www.youtube.com/watch?v=c0TcGjzKbag](https://www.youtube.com/watch?v=c0TcGjzKbag)
