Samsung said to reach 350ppi pixel density with current production tech, we await Super AMOLED HD Plus

Samsung said to reach 350ppi pixel density with current production tech, we await Super AMOLED HD Plus
A Korean source reports that Samsung has cracked the code to achieve 350ppi pixel densities with its AMOLED displays, using the current FMM (Fine Metal Mask) production method. So far FMM only allowed comparatively low pixel densities, which forced Samsung to utilize the PenTile matrix pixel arrangement to achieve those Super AMOLED HD screens in the Galaxy S III, Galaxy Note or the Galaxy Nexus.

Samsung has been test-running the Laser-Induced Thermal Imaging (LITI) production method for AMOLED screens with very high pixel density, as it allows pixels to be laid out with much greater precision, but apparently LITI, albeit cheaper than FMM, couldn't be upscaled for mass production without issues. That's why the report that Samsung has managed to achieve 350ppi pixel densities with FMM for its small and medium AMOLED panels, such as those for smartphones and tablets, is so significant, if true. 

This way Samsung can use the existing equipment that is already churning out millions of those displays, and we are curious whether this will result in a Super AMOLED HD Plus display in its next flagship phones and tablets. This year Samsung broke our hearts by placing an improved PenTile screen in the Galaxy S III, instead of S-AMOLED HD+, but the 350ppi FMM news keeps our hopes high to see an RGB matrix in the next high-end season.

Come on OEMs, time to bring on 1080p displays and 400+ PPIs! XD

seriously, what would be the point of that? the eye cannot identify pixels at around 300 ppi, so the difference in the clarity of the screen at 400 ppi would not be worth the cost. Although, high ppi is a very useful spec to advertise and win customers.

I agree. I see no difference on my 40" Samsung when I switch between 720 and 1080 on the XBOX. 1080 is pointless on 4-5.3" screen.

SuperAMOLED 720RGB will be just ridiculously good.

FYI.... 1080 gets more picture on the screen the 720.

Actually , 1080p is not meaning less on a 5.3 inch screen, like one on the note for several reasons.

1) There are people, like me, who have good vision, and can distinguish the differences between 300ppi and 400ppi. You could argue that because we only take up the fraction of the market, such investments would not be fruitful, but considering a phone like the Note 2 will only sell to a fraction of the market, the technology would go great hand in hand.

2) There is a definite change in image quality when moving to a higher resolution, especially when the resolution of the image in higher than that of the screen. For example. a 2048x1536 image would look significantly better on an iPad 3 than a Transformer Infinity, because even though the res isn't that much higher in ppi, and the distances at which they are held qualify them to be "retina", every detail is accommodated for with the higher res screen, and your eye perceives the image to be much more sharp. Same goes for an iPad 2 vs a Transformer Prime. If they're ppi's are barely that much apart, and you see a significant improvement, image the improvements 100+ ppi would yield.

Same goes with movies and Blu-Ray

That's not true some can definitely tell a difference. Some have better vision than others, some have sub super human sight. Also the closer you bring your eyes to the screen the more evident that difference can be. Maybe for most people around 300ppi density is at the capacity of ppi they could see, but definitelly does not apply to everyone.

I would like to see this new technology on a tablet 7" to 10" or on laptop. At least, 1080p for now.

exactly, anything more than 300ppi is useless...it would reduce the battery life and we won't be able to see the extra pixels as well

and what's next? inventing something above 1080p? take your time and enjoy 720p instead whinning!

News flash.... Above 1080p has already been invented and is already hit the market.... 4k.... heard of it? Basically every new release movie you have seen in the past years was most likely shown in 4k. Sony, Sharp and Samsung have 4k TVs hit the market for home use too..... but as you can guess the price is astronomical.

Pointless resolution? Really? 4k is the sole reason you see such clarity on the 30'x70' movie screen. Because of 4k, you can now see every dimple and wiggle on Scarlett Johansson's butt when she walked in the Avengers. 326ppi on a 3.5 screen is a pointless resolution.

with 1080p displays and more than 400+ ppi you need at least 4000mAh battery to get you through a day, maybe half!

Even though its possible there is no need as the screen size is so small that the human eye wont be able to tell the difference. It would just be wasted opportunity I would rather OEM's make the phones more durable and have longer lasting batteries like the droid razr maxx! and make all phones come with NFC as standard!

actually samsung should work on increasing the battery life instead of concentrating on the resolution....they should also work on anti glare screens, a 720p anti glare display with better battery life is better than a 1080p display without an anti glare filter and lesser battery life

OMG. Can it be a 8.9 inch tablet with 2560x1600 resolution? (About 340 ppi)

why not,the more the pixels in an inch field,the more the crystal live clarity.it depends on manufacturers how much money they want to make out from an innovation,therefore have patience.....

In future,we will see 500+ ppi on a display of a mobile.......mobile display technologies are very fast.....

that would be awesome. Though If they just now "cracked the code" they might not be able to get the supply chains up and running with enough time to give it to the GN2. At worst that means it should be in the SGS4.

Now this is what innovating is > Apple, this is why I love Samsung Products, they actually "MAKE" stuff, not "STEAL"

This is why Samsung is the s**t and the world leader in mobile innovation. You don't hear about Apple, Motorola, HTC, ect. doing stuff like this.

I'm gonna keep my S2 till 1080p Retina Super AMOLED HD Plus is released. And then I'm going to sell my TV.

This isn't any special, Sony had 342~ ppi on their XPERIA S from months ago. samsung better consider quality of their amoleds instead.
