DC has even worse contrast than e-ink.

- layer8 2y agoE-ink contrast is something like 1:15, it's pretty bad.
- Rinzler89 2y ago*) in the realm of electrophoretic displays or with strong ambient light, not compared to some 2000 nit OLED in the dark
- layer8 2y agoMy reference point is physical paper.
- Rinzler89 2y agoYou think e-ink has worst contrast than physical paper? How so?
- layer8 2y agoI hold them side by side.
- dylan604 2y agowhat's the contrast of physical paper in the dark?
- layer8 2y agoWe are talking about e-ink without added edge lighting. I found that if I have to crank up the internal lighting of an e-reader to get adequate contrast, then I may as well use a tablet, because it isn’t reflective illumination anymore to the eye.

- smith7018 2y agoIt's not really a scam but rather a technology that's still in its infancy. I think of it more like the Palm Treo and Blackberry: they're not great but hopefully we're progressing towards the iPhone. I wouldn't buy one at the moment, though.
- Rinzler89 2y agoIt's a scam as in it costs much more than the B/W displays but has worse specs than it.
- mrzool 2y agoSince when does e-ink have bad contrast?
- layer8 2y agoHave you ever compared with actual printed paper?
- mrzool 2y agoNever, and I’m not even sure about the ratio — I just never noticed poor contrast on my old Kindle, which I’ve been using for the last 10 years or so.
- layer8 2y agoPrinted paper (black on white) has a contrast ratio of 1:50 to up to (for glossy paper) 1:200, significantly higher than e-ink.
- AlanYx 2y agoDepends what your reference is. E-ink displays without a lot of layers (especially Carta 1250) have pretty good contrast, on par with matte paper. Some devices with a thick frontlight layer and a Wacom layer and a touch layer are less impressive.
- dredmorbius 2y agoMy Onyx BOOX has at best a background comparable to very dirty newsprint. I find myself reading with the frontlight on under most indoors circumstances, unless I'm in direct sunlight. With the frontlight, it's fine. Text may be somewhat more washed out, but that bothers me less than a darkish background. Under sunlight the contrast is actually about perfect, as white paper tends to be too blindingly bright. My tablet has several layers: capacitive touch, Wacom, and frontlight, all of which probably contribute to the lower contrast. Mind: I'm addressing your "bad contrast" question. I find the trade-offs reasonable, and for reading ebooks (as opposed to Web browsing or other app use), the frontlight battery consumption is quite reasonable. If I'm just using the device casually (e.g., listening to podcasts or checking something quickly) it's fine to use w/o the frontlight, but for immersive reading I'll either have a strong reading light, frontlight, or head for a convenient sunbeam.
