Come to think of it, you only need 2 settings:
1- Off: the majority of the time, when reading in daylight 2- on: A faint backlight to make it readable in pitch black dark rooms. Anywhere between pitch black environments, and daylight, one can either turn on or off the backlight. The weak backlight would be improved by environment light, so the lighter it gets, the less you need to depend on the backlight. As long as you got these 2 bases covered, to be able to read comfortably in pitch black rooms, and to be able to turn it off in daylight; you have basically covered all possible situations. I don't see the need for making the led backlight as bright as tablets or LCD's. |

Please - I'm not trying to be picky, but it is NOT a backlight. A backlight is behind the screen. The PW has a frontlight. It's no harder to use the right word than the wrong one, is it? |

I don't care about the battery issue that some people were talking about. I mean if it does lessen the strain on the battery and save energy that'd be great but I'm not pressed about that because I don't know that the difference is significant enough to get my panties in a twist about. I dislike that I can't rid myself of the light ever. I notice it still even at 1, 0, what ever the lowest setting is. I can still tell it's there during the daylight and would prefer if it wasn't. If I couldn't see it I wouldn't care... hehe Also I do like the slider and have found it useful to turn the light up in certain places where I'd prefer it lower in different lighting or lack there of. I wish someone smarter than I could add a long press option to the light bulb menu icon that toggles the light off and on while maintaining the slider functionality.

Which makes both of us wrong. I say back light, because the light is behind the touch screen. |

Talking of which, why does it have a polarization filter built into?
Doesn't that reduce the amount of light hitting the screen? (since the main function of a polarization filter is to block certain types of light, from certain angles). |

Because the light intentionally leaks out the back of the front plastic layer, it really is a front light (or perhaps a side light if you prefer to take into account only the LEDs and not the light guide layer). In fact, damage to the front plastic layer can cause some light to leak out of the FRONT of that light guide layer, causing annoying light pinpoints to be all too visible. The position of the light is relative to the active pixel layer, not the touchscreen layer. The location of the touchscreen layer has no relevance to whether the PW has a frontlight or backlight.

Just checked one of my tvs - and the light is diagonally from bottom left to top right. On my notebook it is diagonally from top left to bottom right. On my phone it is even more complicated - one direction it is reddish, and orthogonal to it it is greenish. On the paperwhite the light is uniform in every direction - checked with my sunglasses. (my sun glasses have a directional pol filter themselves) |

The light is emanating from the leds, and is radiating between the e-ink substrate and the touchscreen layer, not on top of the touch screen layer, since it's capacitive, the touchscreen layer must be the most top layer of the screen. but anyway, I wondered why someone mentioned about a polarization filter on the PW, and I asked about it, because I haven't yet found much stuff online about that.

No no no. Capacitive touch layer does NOT have to be on top. Go to Amazon and look at their own pictures.
