Samsung using diamond-shaped pixels for 440ppi+ AMOLED panels to debut in the Galaxy S IV
Hexagonal and diamond-shaped pixels? According to "industry sources" that is exactly what Samsung's been experimenting with to achieve ultra high 440ppi+ pixel density for its smaller AMOLED display panels aimed to go in smartphones this year.

Samsung has been developing those by utilizing the Laser-Induced Thermal Imaging (LITI) production process, which is cheaper and allows for much smaller subpixels to be laid out than the conventional Fine Metal Mask (FMM) process it's been using so far for the Galaxy line, for example.

R&D had trouble scaling LITI for mass production, but now it seems that the issues might be behind it, as the hexagonal and diamond-shaped pixel matrices have allowed for much higher pixel densities than the conventional side-by-side layout, and we might see the result for the first time in the rumored Samsung Galaxy S IV 5" Super AMOLED Full HD panel.

Anybody else who thinks that 4.99" is stupid marketing? (vs. simply calling it 5")

Who the hell cares about that .01" difference anyway? (.01" = One-Quarter of a millimetre)

It's not stupid marketing. 4.99" sounds more compact to the average user than 5 inches, not your regular tech junkie like me or yourself. Also, I don't think the S4 is aiming to be a phablet, since most of those are classified as phones that are 5-inches and above. They're merely going for the smallest possible screen size that can hold a 1080P resolution without being a phablet. You have no idea the challenge people have in making screens smaller with a higher resolution.

I got to agree with you. The 4.99" is a super effective marketing strategy. It was used on pricing goods and products. It has a psychological effect to human minds to see that it's smaller than 5.00"

Maybe some time in the near future, but don't expect it to be cheap

Fudge I wanted to get a blackberry for the next upgrade and to move away from Samsung but the s4 is tempting. The key is van they design the phone with the same dimensions as the s3.

I'm beginning to realize the s3 frame is both ergonomical and built for the hands better than anything from LG HTC and definitely Motorola. The combo of SwiftKey and s3 is spot on.

I wonder if there will be some curved flexible screen features atleast for the notifications like they showed in CES this time....

I think diamond (lozenge) shaped pixels will just have an effect on the eye to make it seem taller.
Maybe in a few years we'll master the circle pixels, which would be the best shape for a pixel. That sh*t will look so smooth.

..Thermal Imaging (LITI) production process, which is "CHEAPER" and allows.. Well wel well, that is SAMSUNG, a "CHEAP" Company :P

whats wrong with you? Samsung is not afraid to implememt bleeding edge technology into thier devices and still make it affordable, unlike some companies still sticking LCD technology and selling devices at premium for people like you, OLED for the future and FTW!

Totally agree, Samsung is so stupid trying to lower costs and improve the end product to the customer.

It's a business model that will never last.

Super AMOLED at 440ppi is going to be something if Samsung can pull it off but it is going to have to be that sharp though I think because wouldn't a diamond-shaped pixel layout - if it looks like a wire fence close up - only look more jaggy?

I hope Samsung won't use Pentile matrix on the Galaxy S4, otherwise it will be either Xperia Z or HTC M7 for me

I wish they could just use a traditional RGB stripe, because the pen tile matrix on my GNex bothers me, especially next to my friends Lumia 920. I hope this diamond or hexagon solution looks ok, as long as it gets rid of this Pentile crap. Definitely looking for an LCD display if the Amoled HD is lacking. However I feel like pentile at 440ppi would be good enough.

i don't know if it's the same but I'm pretty sure it's harder to manufacture a 4K oled tv compared to a phone though it's smaller (as it's harder to make larger oled screens i think lol) for instance the one Sony presented at CES. correct me if i'm wrong haha

Dunno man, Pentile and Diamond shaped pixels to make up for not having the ability to provide consumers with full RGB pixels? No go for me. Shouldnt even be able to be called full 720p for the pentile matrix. You wouldnt sell a brand new car to a customer with no doors and still call it a car. (Bad metaphor, but you get what I mean)

Better example: you wouldn't sell someone a car if you told them it got 30 miles per gallon when it only gets that on the highway and not on city streets. But yes I get what you mean.

i thought ppi depended on the resoluton/ screen size ?

31. phonemirer (Posts: 111; Member since: 07 Dec 2012)


i used to though that too, resolution tells how many pixels has the screen, and ppi means how many pixels are there per square inch

I just hope it's not gonna be PenTile again

sammy can make make pixels in the rgb model but the blue has to be bigger in order to compensate for its weakness. please read the f'en articles.

and please wait before slamming diamond shaped pixels. why the heck would a company spend millions for the latest tech to make an inferior technology. at 440ppi the pixel density is so closely arranged it would be nearly impossible to tell the difference between pixels anyways.

i want to know if they solved the burn in problem and will sammy focus on phones with better durability against drops.
