Samsung Galaxy S5: deeper dive in the Diamond PenTile matrix reveals the secrets of the brightest AMOLED display

Samsung Display has just unveiled a lot of the inner works of the new AMOLED display of the Galaxy S5, but now we have even deeper insights coming from an ongoing dissection of the display by Chipworks.

Samsung has been using a Diamond-shaped PenTile matrix since the Galaxy S4, and while the Galaxy S5 also features a Diamond matrix, this time there are some slight, but noticeable modifications. Unlike traditional RGB LCD displays where each pixel is made out of a red, green, and blue sub-pixel, PenTile displays use less sub-pixels. In the Galaxy S4 we had diamond-shaped sub-pixels for the blue and red colors, and an oval-shaped green sub-pixel. In the Galaxy S5, all sub-pixels are now in the diamond shape, and that’s the first change.

The actual arrangement of the pixels has not changed from the S4 - in every 4 sub-pixel diamond shaped block, we have two green sub-pixels, one red and one blue sub-pixels. However, the actual size of the sub-pixels has changed. In the Galaxy S4, the blue sub-pixel was larger than all others by a huge margin, and it was assumed that this is because of the lowest emission efficiency. If that was indeed the reason, it seems that now, the Galaxy S5 has largely fixed such issues, as the blue sub-pixel now matches the red one in size.

This in turn, should have likely resulted in some changes in the OLED filters that Samsung uses. This is important, as this change might be the factor that allows for Samsung’s huge breakthroughs in display brightness. Samsung says its Galaxy S5 is up to 47% brighter than the Galaxy S4 under ambient light, and DisplayMate has measurued up to 25% boost in brightness under less challenging conditions.

Right below you get to see an intimate close-up look of the Galaxy S5 display with its new Diamond pixel arrangement: mesmerizing, isn't it?

Never believe Samsung in there screen statement. Even Note 3 for watching movies or YouTube not that great even though it's a full HD screen, still not as good as G Flex 720p POLED with real RGB that shows more realistic colors and better sharpness due to the 3 Suppixels arrangement unlike Super Amoled 2 suppixels sharing pixels arrangement.

3 sub pixels were used in gs2 years back in superAMOLED Plus and abandoned by samsung due to screen life concern...

But now you are getting into the old "oled vs LCD" argument. RGB is always better, but depending on the screen tech, it's not always practical.

Concerns, schmoncerns, I still have and use Samsung Galaxy S2 and the colors are still perfect even after 3 years. However, I have been postponing new phone purchase because pentile is a deal breaker for me.

If you have ever seen Erika Griffin's videos, when the note 3 came out, she did a blind tests with her family that didnt care about tech. She asked them which they think looks "higher res", the note 3 or the note 2.? The note 2 used an 5.5" RGB 720p screen, while the note 3 used a 5.7" pentile 1080p screen. Everyone thought the note 2 "looked" like it had a higher res. Just saying.

Why should I read it since I played with the S5 couple of weeks ago. Yeah S5 screen better than Note 3 and S4, but still has some yellowish tint on it same as S4 screen.

Are you kidding me? The G Flex 720p is a 245ppi display. When I look at a Xperia U's 280ppi I can see individual pixels (and its using LCD with RGB subpixels), and on Note 3, I can't even discern individual pixels even though it is using Diamond Pentile. You want realistic colours? Change the modes for the screen, it helps a LOT. I can conclude that the Note 3 screens is 100 times sharper than a Xperia U let alone a 245ppi G Flex. You obviously weren't look hard enough at the G Flex or used a microscope for the Note 3's display, because it is TACK sharp.

I'm not saying Note 3 screen bad, but when it comes to watching movies and youtube video in HD, full HD and 4k hands down G filex wins overall. I used both of these phaplets including htc one max.

The xperia z2 will be better. No doubt that! Just wait and I see. Sony invested their recourses developing a brand new display, Samsung only tweaked the technology they already have, and they don't want to invest too much, they need to make maximum profits - typical Samsung...

Do you expect display technology to shift from one flagship to another? Sony developed what seem to look like a brand new display since we all know they have to ditch the old ones on their early Xperia Zs. In contrast, Super AMOLED is one of the most promising displays today that's getting even better as its weaknesses are being addressed. Its improving brightness, wide color gamut, power efficiency are the proof that Super AMOLED is getting mature. You can't say they "only tweaked" it.

"and they don't want to invest too much, they need to make maximum profits - typical Samsung..." iBS Samsung invested in R&D more than any company, iboy.

Even though I like Sony and the Z2, I think that the Z2 will not deliver a better display than the S5. I guess that in some situations the S5 display is better than the Z2's display and vice versa. With the Z3 however, Sony might make a larger jump forward since the Z2 is just an update to the Z1 to eliminate it's most striking weaknesses such as the outdated display.
