My Oasis has splotchier lighting than any early Paperwhite or Voyage I've seen.

What are you talking about? I can't see any cones or light differences... Some people are just too picky

The PRS-700 was a disaster from the go. That's why Sony never released another Reader with a front light.

You've got to remember that the camera can show patchy lighting in cases where the eye cannot make them out.*

Therefore you need to be wary of claiming that your Sony has uneven lighting. If you can see splotchy lighting on that, it's only because you have CCD eyes.



*the camera also adds 10 lbs to the device, but that's a discussion for another day.

Yeah, ashort needs to get his eyes checked for supernaturalness. Perhaps he sees UV or IR wavelengths too, because no one with regular eyesight would ever see that Sony screen as anything but an evenly lit one.

The main problem with the PRS-700 wasn't the lighting, as such. When used with lighting it was clearer than any reader had been up to that time. The problem was that when you used it without lighting - and the reader was designed to be used without lighting in normal usage - it was like reading through thick fog! The light diffuser was cloudy.

That picture, by the way, has massively boosted contrast. Visually the screen did not look like that at all.

My screen does not have a colour gradient. The *photograph* may have, but *yet again* I have to point out that such things are not representative of what the human eye sees! (Apparently you have visual problems too: no matter how many times I say this, your eye skips over it; you persist in using these photos, which I have repeatedly noted are useless, as some sort of definitive proof of anything at all.)

No gradient is discernible in use, which is surely the only thing that matters. That you have to resort to cutting the image up and pasting it in different positions suggests that you cannot discern a gradient in the unmodified photos either. Are you suggesting that no screen is acceptable unless it can be sliced up and its pieces repositioned in different places and still look identical?! Why?

By this point I think you're just looking for reasons to damn all Oasis screens and possibly all Kindle screens as terrible, even when the people posting the photos you're objecting to say that the screens are subjectively flawless and by far the best device screen they've ever owned. Cognitive dissonance is a powerful thing...

You're spinning this wrong.

The purpose of the splicing is not to see for himself if the gradient exists. I too can make out that the gradient exists on the unmodified pictures.

The splicing is done to make it obvious to the deniers that it exists.

For instance all LED TV´s has some uniformity issues to, especially those that are edge-lit.

Kobos don't have the screen problems of the Kindles. It seems to be the flush screens of the Voyage and Oasis and possibly an AR coating that's causing the problems.

Not sure why he's having so much trouble understanding.

Might be a difference, factors such as construction and differences in light temperature might make it easier to pick up. There needs to be a difference on the Kobo as well, since it´s edge lighted and the strength of the field is inversely proportional to the square of the distance from the source.

Anyway, the Oasis looks perfect too me when reading and that´s all that counts. Amazon would do worse if they increased the size of the unit to make marginal improvements :-)

I still wonder if it might have something to do with the transparent conductive layer (I'm guessing they're using Indium Tin Oxide) of the capacitive touch screen in conjunction with the way it's being lit. Current Kobo's use IR touch and the only Kobo to use capacitive had complaints too IIRC (and not just the etching/grid problem).

That could certainly be part or all of the issue as not a single person with a Voyage or Oasis has ever produced photographic proof of having a screen without a color gradient. It seems like it's a problem endemic to the design somehow.

The lighting cone issue is something different and is just due to poor quality control.

[howyoudoin]

Isn't the lighting cone issue unavoidable no matter what as long as LEDs are lined up on just one side?

No. Plenty of other e-readers don't have the lighting cone issue as well as some Oasis models. That problem is hit-or-miss.

[cerem0ny]

The voyage did have a colour gradient but it was only really obvious if you looked very hard, otherwise it was pretty easy to ignore... Is the oasis' faults on a similar scale? Coz i can live with that.
