Japan Display now making 1080p WhiteMagic LCDs, hints at high-end phones with bright screens
It's been hard to appreciate the brightness of WhiteMagic LCDs when they've been limited to lower-end smartphones like the Sony Xperia P. That shouldn't be a problem from now on, as Japan Display has started mass-producing its first 1080p WhiteMagic screen. Like its ancestors, the new 5-inch panel uses white subpixels to reach outdoor-friendly luminosity (840 cd/m2) without excessive power use; it can also match typical LCD brightness levels using less energy. Japan Display hasn't said just which phone makers are using the 1080p screen, but we wouldn't be shocked if company partners like Sony get first dibs.
Sony's stacked Exmor RS phone camera sensors detuned over quality worries
Sony would still like you to get excited about its upcoming Exmor RS stacked CMOS image sensors -- just not too excited. Both the 8-megapixel IMX134 and 13-megapixel IMX135 are scaling back from their original RGBW (red, green, blue, white) coding to an ordinary RGB over concerns that they aren't meeting Sony's "image quality standards" as originally designed. Consequently, either sensor will be less sensitive to light and diminish some of that high dynamic range magic. The company also doesn't want to get our hopes up for a quick arrival on shelves and clarifies that there's a phased launch starting in January. Mobile shutterbugs may be crestfallen knowing that Sony won't have the best possible camera sensor in future Xperia phones, but the honesty at least guarantees that the company gets a timely return on its $994 million investment.
Sony WhiteMagic LCD promises magic formula of better brightness, lower power
How do you make a brighter LCD without murdering battery life? Simple. Add a white pixel to each RGB trio, creating an RGBW panel that pumps out more nits without recourse to the backlight. We've already seen this technology in action on a tablet-sized screen from Samsung and Nouvoyance, and now Sony's come up with an OEM 3-inch panel that it hopes will prove popular in smartphones and cameras. The VGA screen is claimed to double brightness without increasing power consumption compared to conventional panels. Alternatively, it has an outdoor mode which sacrifices this power-saving in favor of doubling brightness -- although, when it comes to the sunlight problem, we're still hoping that PixelQi's approach will eventually come of age.
Samsung and Nouvoyance show off power-sipping, pixel packed Pentile display (video)
Samsung is seriously stepping up its slate screen game with its 10.1-inch 300ppi panel that we told you about last week. We just got to see the display in person at SID 2011, and can confirm that the presence of Pentile pixels should no longer be a cause of concern. Nouvoyance, who designed the display, told us that the panel's RGBW pixel configuration makes your whites whiter and brights brighter (up to 600 nits worth), while consuming 40 percent less power than conventional LCDs. The company also told us the tech's been around for awhile, but that market forces conspired to keep it concealed -- though after seeing it in person, we can't fathom why it didn't make it into Sammy's stellar new slate. Pixel-density people shouldn't pout, however, as devices packing the display will drop by Q4 of this year or Q1 2012. Video explaining why you should join the RBGW revolution's after the break. %Gallery-123857%
Samsung and LG to showcase high pixel density LCD panels for tablets at SID 2011
It's a well-known fact that LG's already dominated the pixel density race in the smartphone market thanks to the Retina Display inside the iPhone 4, but we've yet to see similar technologies making their way to larger devices. That could change very soon, however, with Samsung and LG both announcing larger high-density panels to be showcased at SID 2011 next week. From Samsung we'll be seeing its 10.1-inch 300ppi prototype LCD panel, which rakes up an astonishing resolution of 2,560 x 1,600 under the battery-friendly PenTile RGBW matrix (not to be confused with AMOLED and Super AMOLED's RGBG arrangement). What's more, Samsung also teases "commercial availability" for this technology later this year. Things are a bit vague with LG -- no specific resolutions are mentioned in the pre-show announcement, but we're told that the company will introduce "a full line-up" of "ultra-high resolution" Advanced High Performance In-Plane Switching (AH-IPS) products, including 3.5-, 4.5-, 7-, 9.7, 55-, and 84-inch panels, with a "greater number of pixels than the PPI that can be recognized by the human eye at a typical distance" -- a proclamation typically reserved for the iPhone 4's 326ppi Retina Display. Of course, LG could be misleading here -- the 9.7-inch panel brought up in the press release could just be the exact same 1,024 x 768 IPS display on the iPad, but we'd be surprised if LG doesn't have a similarly-sized prototype to fire back at Samsung's 10.1-inch 300ppi panel. Well, keep an eye out for our SID 2011 coverage next week and we'll let you know what goodies we find.
Hitachi showing off color version of Albirey e-paper
Now that monochrome e-paper is a pretty standard affair, those at the forefront of e-ink technology have moved on to perfecting the real killer app, which is full-color displays. We've already seen a tiny color model from Fujitsu, and a larger, but only two-color offering from Bridgestone, and now Hitachi -- maker of the black-and-white Albirey e-paper -- is showing off a 13.1-inch version of this product will an impressive 4,096-color palette. Apparently the power-saving "RGBW" filter enables the device to display bright whites as well as deep blacks, but the trade-off is the unit's rather underwhelming resolution of just 512 x 384 pixels. Therefore, we probably won't be seeing color eBooks anytime soon, but the low res should be adequate enough for certain types of signage that would benefit from the paper's ability to hold a picture in the absence of power; we think they would look great advertising all the quality products found at Engadget's retail location.[Via MobileRead]
