[Screendoor effect] pentile vs rgb

Hello,

do you think a pentile display (like samsung oled) would make the screendoor effect look better than the RGB one ?
At first we can think that like there is less subpixel in pentile, the subpixel would be bigger.
But.. like the subpixel have a whole different shape and color than RGB, maybe it helps removing the "grid" effect, with something a little more blurry.

In pentile the pixel matrix seem harder to perceive there is less this "grid" effect i think.

Galaxy note 2 use strip Rgb
Gs3 use RGBG pentile
Gs4 use pentile diamond matrix

    thats obvious, because the galaxy note 2 is NOT pentile. ;)
    only the galaxy S serie is pentile.

    And my observation is even more focus on the diamond matrix

    Good point.
    (It's still a different arrangement to the rift panel)
    Although it's not just the S series. The first Galaxy Note was RGBG pentile.

    On my Galaxy S (which I now use as just an alarm clock)... urgh. I think I prefer the screen door effect.
    With higher res it's probably ok, but at the current res (which is still higher ppi than the rift, 233ppi vs 215) areas of white become a checkerboard of red and black (really blue, but looks black), with faint thin green strips. The red pixels are very dominant. It needs much more than 233ppi to make the pixels mix.
    I might bring a rift lens to work on monday and ask if any of my students have a galaxy s3 (306ppi).

    yeah but galaxy S1 was using "white" subpixel. it was a strange pentile actualy...

    Looks similar to your S3 pic except with slightly larger blue sub pixels.
    Wikipedia lists only 4 motorola phones as using white subpixel RGBW pentile.

    This is my S1 through a macro lens:

    As long as we can see black "line" in the macro, it's obvious for me that we will have a grid effect.
    I really wonder how it would look like with a diamond matrix

    The Galaxy Note 2 is Pentile.
    Only the Galaxy S2 is not Pentile.

    False. The GN2 is indeed an rgb arrangement however it is not a stripe. It is still not pentile. There are 3 subpixels to every single array element in the note 2's display. This is specifically why I went with this phone over the s3 or even s4. The 720p amoled screen on the note 2 is without artifacts and is the last good display Samsung has used on a phone.

    I really was thinking about GN 1 when reading GN2, probably because it came out at the same time than GS2.
    But yes only GS2 and GN2 are not pentile.
    Unfortunely.
    I would prefer Samsung not pretend to have HD FullHD and a lower resolution without pentile.

    This is why I stuck so long to the GS2 and also because I wanted the padfone, and I have the padfone inifinity a86 now
