*edit*

Oh, jesus christ. You posted SCREENSHOTs, again, of a display to prove a point?! Why can you not grasp the fact this wont work? If you took photos with an actual camera, this would work. Screenshots do. not. prove. anything. with regards to the way the display in question is showing you an image.

Oh my god. Again, I'm going to apologize to the OP for destroying their perfectly good thread with a single off the cuff remark.

Now, as for your post.

*facepalms* *bangs head on desk repeatedly*

Let us just start tearing apart your post. I usually refrain from being a dick, but in this case, the flagrant disregard for comprehension of ones writing is making it justified.

If you know nothing on a topic, don't comment on it. Research things. Don't take something pertaining to an entirely different type of technology, apply it to something else not even being discussed at that point in time, and then act smug with your proof that I'm wrong. You will just end up looking like an idiot.

1. I mentioned only older style pentile OLEDs versus newer pentile OLEDs versus standard RGB striped LCD panels. I never once mentioned eink in this discussion (I believe, I haven't reread everything).

2. You took my words, which were directed at one style of pentile OLED (in this case, the screen on the GN1), and somehow applied them to the eink panels on our beloved edge's.

3. I already touched upon why DPI, when in reference to older pentile screens, is an almost meaningless as well as extremely misleading number. Let me explain, again, why: A "pixel" on a display is broken into, generally, a couple of subpixels. These are used in varying intensity to produce the colors your eye sees. Pentile screens *share* subpixels. There is no distinct grouping of subpixels into one pixel unit.

A standard LCD, for the most part, has subpixels groups together into one pixel unit, not sharing any subpixels with neighboring pixel groupings. Now, the PPI/DPI on a display with distinct subpixel groupings is a pretty accurate number. On pentile screens without them, it isn't. It is an *apparent* density and resolution more so than an actual one.

This has been argued many times and the numbers they give are valid in their own right. I only mentioned all this originally because people get stuck on a number and use it to judge against everything without truly understanding it or really comprehending the vast number of other things that go along with something.

4. You took a *photo* of your screen. Which is good! This actually shows people what it looks like. Unlike the previous posters *screenshot* which tells you absolutely nothing other than the font he is using and the colors on the display (which is also pretty meaningless as each display is going to show different colors.)

5. Now. Eink. I love eink. Yes, the DPI is relatively low. Yes, stuff can be *blocky* at times. Yes, it isn't perfect.

The reason I like eink is eink panels do not have normal subpixels. They do not operate, at all, like standard LCDs, OLEDs, or any other common display on normal computers and tablets. They use positively and negatively charged balls of material in tiny tubes controlled with an electrical grid. Its, honestly, fascinating. There is very little space between the individual pixels. The very method of function allows for really nice, print-like, rendering of text. The text on eink is, generally, a little fuzzy, but it is fuzzy like print (which I don't mind and actually rather like) and it does not have a well defined pixel grid as well as visible random colors like you will get on a color display that is anti-aliasing text as well as on pentile screens that tend to have color artifacting simply due to their design.

Read this : http://www.eink.com/technology.html

The fact the screens are greyscale helps alleviate the blockiness to a certain extent as your eyes are not as sensitive to shades of grey and the rendering, with a good rendering engine and display controller, looks very very good. Up close, depending on the font size, font used, type of book (this will affect the way the screen looks as a different rendering engine will probably be employed), the text may look pretty bad. There is just no way around this on any screen type. Even on an HTC DNA with a ~440 ppi striped LCD. You are still going to end up with jagged, crappy fonts, depending on the situation. I'm not saying that wont happen.

Now, back to DPI for a moment: I don't mind low DPI screens DEPENDING on the type of display in use and the arrangement. On a lot of pentile displays, even at farily high "DPIs", there is a lot of dead space between the subpixels, which is noticeable and annoying to some people... Like me. The fact it isn't in a crisp pattern is what does it to me more than anything. It's like staring at a bunch of dots in no real pattern. Low DPI RGB striped LCDs exhibit a grid that is readily visible between their pixel groupings, but its a tidy, organized grid which doesn't bother me all that much. And even on a lot of lower DPI LCDs, the grid isnt that visible because the subpixel elements are *large* compared to most OLEDs, so there is less dead space between them making the grid even less noticeable even though the DPI is, in some instances, much lower.

Now, can we kill this? We are beating a dead horse.
