    Samsung must be excited at the amazing ideas they are working on because they recently shared a series of infographics to show off their newest near future tech. The above infographic is just one of several that Sammy showed off. It's an example of their planned foldable display tech which we shared some concept pics of a couple days ago. That's not all they have planned though. Here's a quick bullet-point list with some of the tech they are working on:
    • Foldable Display - goes beyond just flexibility and bending
    • 560ppi HD Displays and later 800ppi 4K Resolution Displays - Samsung is planning displays which can achieve astounding levels of resolution and pixel density
    • 16MP Isocell sensors - Samsung wants to seriously up the ante in the digital camera department for smartphones
    • 64-bit Custom ARM processors - of course we have heard about this one already but it will interesting to see what they can do with it
    • More efficient uses of power in CPUs, NFC and more - who doesn't want better battery life?
    That's just a brief glimpse of Samsung's plans. Most of this tech isn't too far off either. While most of it won't come about until 2015-2017, some of it will be available next year. Here's a link to six of the infographics from Samsung: http://www.droidforums.net/forum/dr...ear-future-tech-infographics.html#post2486642

    Foldable displays are really interesting...You could have a standard 4.7" display that unfolds into a 7" tablet - even bigger if you think a tri-fold concept that would get you up to 9" diagonal.

    4K resolution...um...wow. I mean sure, its a great marketing feature but 800ppi on a phone. Thats overkill and a half.

    I thought 720p was the max anyone would need on a 5" or smaller phone. I thought the resolution on my Droid Razr HD was great, and hearing about 1080p phones made me shake my head. But I got my Nexus 5 Tuesday, and all I can say is wow. The difference was immediately noticeable to me. The display is gorgeous and text is very easily readable even when it's small. I've learned to bite my tongue until I see it for myself.

    4k display on the phone? Why? So it can drain the battery faster and make apps load slower? Human eye can't tell the difference between 300ppi or 800ppi from 2 feet away. Why stress the device for no reason?

    In my opinion samsung is concentrating on the wrong field. Figure out your battery problems and fix your pathetic radios. Then star worrying about numbers which make no difference.

    That's 2 feet bro, I look at my phone from like 1 foot max lol. In all honesty, you probably can't tell the difference in number of pixels, but I'm sure you would be about to see the difference in quality. Go compare a 720p phone with a 1080p in person and you will understand what a difference it actually makes.

    Like I had said, I was not a believer until I saw it myself.

    I am not disagreeing with the masses here that want "better quality" in image displays, but really...800 PPI, or even 560 PPI??? I'm sorry, but in terms of actual full-color pixels, even 560 PPI it is definitely overkill at even the 1' distance remarked, unless they are speaking of individual color sub-pixels.

    I've said before that if you were to poll all those out there and determine the PPI of their computer monitors, you'd find they're maxing out at about 160 PPI. Granted, they're at a greater viewing distance in most cases, of about 18", but still that doesn't equate to 560 PPI at 8".

    From Wikipedia;

    The maximum angular resolution of the human eye at a distance of 1 km is typically 30 to 60 cm. This gives an angular resolution of between 0.02 to 0.03 degrees, which is roughly 0.6 arcminute per line pair, which implies a pixel spacing of 0.3 arcminute.[SUP][5][/SUP][SUP][6][/SUP][SUP][7][/SUP] 20/20 vision is defined as the ability to resolve two points of light separated by a visual angle of one minute of arc.[SUP][8][/SUP] That's about 300 pixels per inch for a display on a device held 10 to 12 inches from the eye.

    So what that is saying is that a 300 PPI display should look no less sharp to a 20/20 eye at 1' than a 560 PPI display. Now, that is making an assumption that the 300 pixels per inch are full-color pixels (i.e. 3 sub-pixels of colors, or 900 sub-pixels per inch). Using the RGB or CMY color schemes to achieve full color, and considering if each individual color pixel whether Red (Magenta), Green (Yellow), or Blue (Cyan), were actually counted as an individual pixel and not as a part of a 3 or 4 pixel subset, it would then mean that sub-PPI might need to be as high as 900 or 1,200 PPI to achieve a net result of 300 PPI in pixel subset resolution.

    It has also been argued that this 300 PPI number may be low given other variables. Many argued that the Apple's "Retina display" at 326 PPI was still lower than human visual acuity, so the argument for 441 PPI as in the Samsung Galaxy S4 can be made perhaps...but still not 560 PPI or better, again on 5" displays at even 8-12".

    Also, sharpness and color saturation and purity are two entirely different things. To achieve greater color range and intensity requires more individual color pixels (and even varying shades of each color). Samsung's S4 uses a different pixel arrangement than other displays called "Diamond pixels" to achieve greater image quality (see below).

    By using the eye's varying levels of sensitivity to certain colors as a guide to pixel size and arrangement they've increased image quality without needing to go to such extremes in pixel count. The human eye sees Green (about 495–570 nm) best with maximum sensitivity at about 500 - 555 nm, and sees both Red (620–750 nm) and Blue (450–495 nm) far less easily. Of the three colors, Blue is the most difficult for the human eye to see (see below). Notice how wide the band of Green range is (Blue-Green to Yellow), how much smaller the pure Red range is (Orange to Magenta), and how tiny the Blue (Blue to Violet), range is?

    View attachment 67633

    To create a laser that's easily visible in the Green range only requires minimal power. To get a Red one to the same perceived brightness requires considerably more power, but to get a Blue one that looks even closely as bright requires massively higher power.

    So Samsung made the Green sub-pixels smaller than the Red and Blue, but arranged the Green in rows and columns, and the Red and Blue in alternating, intermingled X patterns to achive a hybrid Pentile display giving greater color accuracy and still allowing the sharpest images. Really it's quite impressive, but not because it's 441 PPI - more so, because it's more natural in tonality and clarity - i.e. appearance.

    You sure what you're noticing isn't just improved contrast and brightness? I would guess the glass can make a difference, too, just like on tv's. Not to mention font tweaks/idfferences. I'm not sure how one would go about a legit apples-to-apples comparison.

    I understand that you like to over analyze these things with your science and math, but what I'm saying is not that complicated. From my personal experience, I can see a huge quality difference between the Nexus 5 and Droid Razr HD. For anyone to make a statement before seeing and experiencing themselves seems foolish to me now that I have seen it for myself. Having said that, I'm not saying that we need infinite amount of resolution on our phones. I assume there actually is a limit to where we will no longer notice a difference. It could be 1080p on a 5" display, it could be 4k on a 4" display, all I can say is "don't knock it before you try it."
