If the rumor turns out to be true, how is OLED screen compared to E-ink in terms of book reading? |

OLED panels are active emissive displays, that constantly refresh just like LCDs. Just a bit pricier. You get better color, slightly longer battery life, slightly thinner form factor. In other words, the benefits for ebooks are essentially zero. But it looks cool on the specsheet. A typical Apple choice.

One advantage the OLED displays do have is that they are sunlight readable. That's important to many people.

I'm speaking from personal experience, X. I have a DAB radio with an OLED display, and it's perfectly readable in full sunlight.

The 122-hour thing struck me as an error back when it first leaked out, and it was pretty ridiculous that it was echoed by a bunch of sources without question.
Huh? Generally speaking, sunlight readability is one of the primary weaknesses of OLED displays. A few crank out enough light to be somewhat usable in the sun, but that's not an ideal situation when you want to be saving power. |

Really? As I say, my radio's display, which is unquestionably OLED, is perfectly readable in full daylight. It seems to be a reflective-type display for that purpose, rather than relying on emitted light. I've not seen any other OLED screen, so I'm going off a sample of one, I must confess!

OLED is completely emissive. There is no such thing as a reflective OLED. In order to work in the sun, it needs to put out a LOT of light for its area. |
