Ultra high-resolution mobile displays to be showcased by Samsung and LG in Los Angeles next week
Samsung's baby is to sport the astonishing 2560x1600 pixels of WQXGA resolution, reached using the PenTile matrix of Nouvoyance, whose intellectual property Samsung bought in 2008. Before you scoff at the fact that it is using the PenTile matrix arrangement, it is not the RG-BG one for AMOLED displays, which we compared yesterday with a Samsung Galaxy S II with a normal RGB stripe matrix, and found to be inferior. From Samsung's press release:
"- This 10.1-inch tablet panel is capable of 300 cd/m2 of luminance, yet uses 40 percent less power than that used by legacy RGB stripe LCDs in power-saving modes.
- An outdoor brightness mode of as much as 600 cd/m2 luminance enables viewing in bright ambient lighting.
- The display's color gamut is 72 percent., allowing greater color realism than legacy RGB stripe tablet displays that have a typical color gamut of 55 percent NTSC.
- PenTile technology achieves 300 dpi resolution with two-thirds the number of subpixels, maintaining the VESA/ICDM display resolution standard."
Let's put the numbers above in perspective. First off, Samsung touted the move to a normal stripe RGB matrix for the Super AMOLED Plus display in the Galaxy S II as an advantage over the PenTile RG-BG pixel arrangement in the Super AMOLED on the Samsung Galaxy S, citing that we now have 50% more subpixels per pixel than before.

Even if in reality things don't appear as crisp, 2560x1600 will be more than enough pixels to significantly enhance the viewing quality over anything that's currently on the market. What's more interesting for us is the increased brightness. The Super AMOLED display at full swing shines with 365 nits, whereas Samsung claims 300 nits on this tablet display, and that's in power-saving mode, going all the way up to 600 nits in "outdoor brightness mode". For reference, Apple's iPhone 4 screen has been measured at peak brightness to show 541 nits, and the iPad 2 display peak brightness is measured at 410 nits. We have an LG Optimus Black in the office, which has NOVA display with 700 nits of brightness, and LG claims that's the human eye threshold for decent direct sunlight visibility.
The 72% of the standard color gamut that Samsung's 10.1" high-res tablet display is able to reproduce is also larger than the 64% on the iPhone 4, and the 61% on the iPad 2, but still has a way to reach close to 100% realism.
Well, LG is not sitting still while Samsung is making these announcements. It came up with a new version of its IPS-LCD screens, called AH-IPS (Advanced High Performance In-Plane Switching). The press release states it sports 1.5 to 2 times higher resolution than LCD displays with typical such. We'd assume LG means the ones sporting 480x800 pixels for smartphones and 1024x768 for tablets, since the "Retina Display" is not exactly typical with its 640x960 pixels. Not that 1.5 times or even 2 times those sound bad at all for the AH-IPS displays with 3.5", 4.5", 7" and 9.7" sizes, that LG will be demonstrating at SID 2011 next week. In addition, LG promises wider color gamut, better light transmission for improved outdoor visibility, and lower power consumption.
Promises and tech specs aside, we can't wait till next week to see how the naked eye of attendants perceives both Samsung's and LG's new high-resolution mobile displays.

Is Apple interested on Samsung 10 inches display with 2560x1600 resolution PenTile RBGW for future iPad?
Apple must stop suing Samsung if Apple needed Samsung components.

they all buy from each other. Samsung should try and be a little more creative as well. If i came up with the iphone, i would probably take samsung to court as well.
but thats just business.

They buy from each other? Don't know where you get that from but the big boys don't. Only Apple depends big time on Samsung, LG etc. not the other way around. Apple has no technology only great marketing. oooh yeah and lawyers too.

bucky you are a moron. apple did not create and originate the os, the square, the app store, etc. what they did was create an unnecessary barriers that inhibits other companies from advancing on other people's technology, etc. Apple fanboys and certain Android fanboys are complete morons. It would be nice if the moderators allowed only comments that were related to the original posts.

lol and you take this too much to heart. Relax, your parents wallet can get you any phone you want.
You are honestly going to tell me the sgs1 didnt look like the 3gs? who is copying who?
Now, the sgs2 doesnt look at all like the iphone 4?
I never said either phone sucks, just if it were my phone i would take it to court as well.

i kinda agree to the both of you... but look at it this way apple not suing the china companies that makes fake iphone that looks exactly the same and named exactly the same? is it bec that the product is not popular? not considered competition?
now do see apples intention? the way i see it, its not about the copying the design its more about apple is looking for something to be taken to court as part of the strategy for competition sake...
