Samsung Galaxy TabPRO 10.1 coming with Pentile RGBW screen

The difference is small, but noticeable in real-life. To better understand why it’s there and what it’s all about, we’ll quickly go over the essence of Pentile displays. Every screen is comprised of pixels, and traditionally LCD displays come with red, green and blue sub-pixels, that make up the whole pixel. Hence, such LCD screens are called RGB (red, green and blue). A Pentile display is different because it features other sub-pixels, and the RGBW one in the TabPRO 10.1 has an additional white pixel.
The motivation behind having an additional white pixels is to achieve higher brightness. Since LCD displays are back-lit, the white sub-pixels act as a simple filter that lets more of that backlight in, and this makes the display brighter overall. The increased brightness comes with the upside of better outdoor visibility, which is an important improvement.
Nonetheless, a Pentile RGBW screen also has the downside of having less subpixels (since the white does not convey any color information), and in reality that makes some of the content look a bit grainy, pixelated. At first, it might sound strange that a 2560 x 1600 pixel screen can look pixelated, but in some icons the slight jagged edges are definitely noticeable to pixel peepers.
Right below is a close-up image of the TabPRO 10.1 screen showing that extra grainy texture. Interestingly, it seems that the rest of Samsung’s CES 2014 tablets actually features a full RGB screen, so it’s just the 10-incher that comes with Pentile. What do you think about this, is that slight jagginess a concern for you?

what is it with phonearena and their so much enphacy on pentile screens? For christ seek, even the note 3 uses pentile but the truth is it looks more beautiful than the average lcd screen. If no one told you it was pentile would you even notice?

How is pentile a gimmick? Did you even know what it is? Grow a brain, buddy!

Note 3 has very high DPI, pentile has minimal negative impact, but it is still there. On tablet with lower dpi it is much more visible. I have very sensitive eyes. I prefer full RGB subpixels and I'm glad phonearena report this so that I can make apropriate purchase decision. That's also the reason I prefer S4 Active with full RGB display, not regular S4 with Pentile display.

Why is everyone crying simply because P.A. simply decided to share a detail, however mine to you it may be, that will possibly be overlooked/go unmentioned by the vast majority of others? While I agree that a Pentile display screen doesn't make a device unuseable or of poor quality by any means, I'm also pretty sure that anyone spending such a premium that's bound to be attached to a high end Samsung tablet would like to make their purchase with as much information as possible, especially considering the screen is arguably one of the most important components of any smartphone or tablet.

Bitch, my 10.1" tablet with 1280x800 resolution is already sharp enough for me. Don't complain about this screen

It doesn't matter. Either way a 300 ppi pen tile should still be sharper than the lower ppi iipad air screen and definitely still sharper than the Xperia Tab Z , surface 2, and lumia 2520 1200p screens.
