Nouvoyance and Samsung demo ultra-high resolution touchscreens
TWO COMPANIES have in a team effort pried away the ultimate eye-candy trophy from the grasp of Steve Jobs and his Ipad 2 by demonstrating a 10.1in WQXGA 2560x1600 resolution RGBW display at the SID Display conference in Los Angeles.
While simply saying that the technology, which goes by the name of "PenTile RGBW", is equivalent to having a 10.1-inch 300 dpi colour print in your hands, that just wouldn't be enough. However if we blurt outright that the pixel density is more than twice that of Apple's Ipad 2 display, then you'll get a real idea of what this means.
The "W" in RGBW stands for white, as it was through the addition of a fourth component colour that the firms have been able to increase the pixel density so much. The side benefit of this is that it also reduces the number of transistors needed in a panel array by half, which in turn also halves power consumption. Of course, being that LCDs suck quite a lot away from a mobile device's battery life, halving the power consumption of an LCD is tantamount to extending the battery life by about 10 per cent, which is quite an accomplishment.
There are, however, other upsides to this. This is a technology that puts touchscreen resolutions up to desktop display levels. The RGBW display has twice the transmittance of a regular touchscreen and will easily double the brightness of current devices. The 300cd per square metre brightness can go as high as 600cd in outdoor mode. Contrast figures have not been given.
Samsung has a lead here and is taking care of bunging these displays into its devices. By the end of the year, which is Samsung's predicted commercial availability, we should have 2560x1600 Samsung Tab III's running amok in the market. Let's just hope the graphics hardware can keep up.
So, Nouvoyance developed it, and Samsung is marketing it. But it's not an exclusive. Companies like Wacom and others might want to crack open their piggy banks and spring for access to some of this display technology. µ

Okay, I'm not a UberGeek, but at that resolution, isn't the start button (or whatever else) going to need a microscope to be seen, and how would one touch anything without touching ten other things unless they're a go$%amn fairy with finges 1 mm wide?
What is the bit depth on these displays? Is it full 24 bit IPS or a 16 bit TN faked up to 24 bit? Some combination?
My bad, i've missed the words "PenTile RGBW".... I do not need this cr#ppy piece of dirty trickery PenTile RGBW even close. It is the same as PenTile RGBG like in Galaxy phones in terms of resolution - exactly the same amount of total subpixels. Imagine that this @#$#%^% will have the same amount of RGB subpixels as the current XOOM 1280x800 just one white subpixel added! This white pixel will add some brightness to LCD screen by ~40% and marginally increase resolution compared to 1280x800. But if instead of LCD there will be an AMOLED kind of screens, then even this advantage vanishes. WOW... What the dirty manipulators are those at Samsung.... Yea, sure 2560x1600 screen....not even close!!! Same old cr#p, better wrap.
...to edit an article without listing the revisions. In this case it made your comment seem like the typical glazed-eyed-fanatic-Jobsian-tunnel-visioned-fanboi that we all love to bash here in the INQ forums. As you have already surmised, this is not a pro-Apple conduit.
Anyway, thanks for the clarification. Next time I may go easier on an "alleged" fanboi comment...or not. ;^)
Cheers!
To the iPhone 4 in the original draft, not the iPad 2. Shame that the Inq doesn't feel the need to indicate when an article was updated/corrected, this isn't the first time they've done this kind of thing.
...then my apologies to you; however, the article is about tablet displays as even the byline declares, "...puts Apple's Ipad 2 to shame". So you're saying there was no mention at all of the Ipad2 anywhere in the article and byline before your post? Hmmmm...
We all need that kind of resolutions.
This is what i am telling here for ages.
The DPIs for tables have to be 300 DPI, period. Means 2560x1600 for 10" and even more like 3600x2250 for 14" tablets. 14" is exactly the standard A4 page format, or size of regular journals. I use 3600x2250 resolution on my larger monitors (panning with the mouse, of course), and wait when i will not need to pan
@Vincent: That was fun!
ScrenResolutionsSuck=1
DoWhile ( ScrenResolutionsSuck<=3840 )
ScrenResolutionsSuck = ScrenResolutionsSuck + 1
Print*, "Vincent, Kudos, that was great!"
Enddo
It looks like the author applied a little after-the-fact editing.
@Bryce - given that it is only MANUFACTURED by Samsung for Nuovoyance, Nuovoyance may get a little upset if Samsung refuse to fill a large order like that.
...or an effing iDiot. The article compares the pixel density to the Ipad2, not the POS Iphone4. Had you included the WHOLE quote as: "However if we blurt outright that the pixel density is more than twice that of Apple's Ipad 2 display, then you'll get a real idea of what this means."
I'm always amazed that you Jobsian morons are always trying to keep your eyes wide shut regardless of the facts. How sad for you and the rest of the SJ lemmings.
Now go drink your Kool-aid like a good little cRapple fanboi.
If and when it is in a shipping product then you can talk about putting a shipping product to shame. This article like many of your smacks of Microsoft's, but our next version will be better than the other guys, really. You may have noticed the pre-announcing things is not "freezing" the market anymore.
Expect the next iPad to have a resolution of 2048×1536 and it has the graphics hardware now to drive that.
The real issue is that hardware specks are great to show off but if your software sucks what good is it. All of the other tablet manufactures still have to deal with software and services that suck.
No real competition now, and a long way to go to catch a rapidly moving target.
Sorry, to burst the Apple fanboy bubble, but Samsung and Apple are at odds, and unless they kiss and make up soon, plan on seeing this only on Android devices.
"if we blurt outright that the pixel density is about 50 per cent more than that of Apple's" then you'd be wrong. The iPhone 4 has a pixel density of 326DPI. It might make a good display for the iPad 3 though.
