Built in light, dust betwen layers possible?

[eksor]

Hi:

I have a PRS-700, with built in light. In this device there is a gap betwen layers and thus, the dust inside, betwen layers is very visible with built in light on.

I wonder if this can happen with kobo, nook or kindle.

Additionaly, my device has a resistive touch screen obviously above the other layers. When using it outdoors or with external light, some glare may occur. I have read that kobo touch screen is IR based (like new Sony) and thus there is no layer above e-ink screen. Is this correct?

Regards.

PD: I'm pretty happy with my device, because of this I want my wife to return it to me.

The technology has moved on a lot since Sony's attempt at a built-in light, and is much improved. The light guide layer is on top of the e-ink screen but you don't get any dust (at least there have been none reported) or glare, fingerprints don't show up on them either.

You are right that the Kobo still uses the standard IR touch screen, whereas the Kindle has a capacitive touch screen and therefore requires another layer, and it's actually between the eink screen and the light guide, so all of them have a light guide layer at the top, above the eink screen.

If you like the built-in light, you really would be doing yourself a favour by taking a look at any of those newer models. None is perfect - the Nook has screen durability issues with the light guide layer, Paperwhite's have colour hue issues and people are sometimes having to do a few exchanges before getting a 'good' one & the Kobo's light can be a little too bright even at the lowest setting. But the very slight contrast they might lose over ereaders without a built-in light is fairly minimal, and the screens on them all will look far, far better than your PRS-700.

Thanks!

I think that finally The Three Wise Men will arrive with a fnac rebranded kobo for my wife.
