AUO boasts highest resolution AMOLED panel for smartphones

Posted by wicked April - 11 - 2014 - Friday Comments Off

AU Optronics Corp, or AUO for short, has unveiled a variety of high resolution displays for the electronics market. Among these is what the company claims to be the world’s highest resolution panel for smartphones using AMOLED display technology.

For sure, this isn’t the first time AUO has announced a high resolution smartphone panel. Early this year, it revealed a WQHD screen for smartphones as well. That one had a screen resolution of 2560×1440 pixels, sometimes referred to as 2K resolution, in a 6-inch a. This latest display, however, is significantly different.

First is the size. This new AUO panel crams that same WQHD resolution in just 5.7 inches, giving it a pixel density of 513 ppi. While still within phablet range, the difference of 0.3 inches can still make a big difference, especially when you factor in bezels. Secondly, and perhaps more importantly, this display employs AMOLED technology, while the previous display only used LCD. AMOLED has long been touted as the superior display technology, at least when it comes to refresh rates and visual fidelity. although, depending on the implementation, power draw and visibility under bright light may vary.

Display technology isn’t the only thing going for this panel, however. It is also quite slim, measuring only 0.57 mm thick. A special AUO driver also makes it super sensitive to touch input, supporting up to 10 touch points. AUO is also planning to develop such AMOLED displays in smaller 1.6-inch sizes to try to supply a growing generation of smartwatches and other wearable devices.

Samsung producing Graphene, the material for flexible displays

Posted by wicked April - 4 - 2014 - Friday Comments Off

All those interesting flexible displays we see now and again at trade shows have one thing in common: they’re not available for purchase. Companies showing the bendable, flexible displays commit to bringing them to retail, but offer no timeline for when that will be. Samsung may have just had the first break, though, and mass production could come sooner rather than later.


The Samsung Advanced Institute of Technology has had a “breakthrough sythesis method” in the development of the material used for the screens, called Graphene. The flexible material has other benefits as well, and can be used for other purposes. When compared to silicon, a material used in most hardware components, Samsung says Graphene has “one hundred times greater electron mobility than silicon”, and is more durable than steel. It’s flexible, and also has a high heat conductibility. Samsung notes it’s perfect for “flexible displays, wearables and other next generation electronic devices.”

Samsung accomplished this breakthrough with the help of Sungkyungkwan University. In a blog post, Samsung announced the breakthrough, and gave a glimpse into how it was accomplished:

Through its partnership with Sungkyungkwan University’s School of Advanced Materials Science and Engineering, SAIT uncovered a new method of growing large area, single crystal wafer scale graphene. Engineers around the world have invested heavily in research for the commercialization of graphene, but have faced many obstacles due to the challenges associated with it. In the past, researchers have found that multi-crystal synthesis – the process of synthesizing small graphene particles to produce large-area graphene – deteriorated the electric and mechanical properties of the material, limiting its application range and making it difficult to commercialize.
The new method developed by SAIT and Sungkyunkwan University synthesizes large-area graphene into a single crystal on a semiconductor, maintaining its electric and mechanical properties. The new method repeatedly synthesizes single crystal graphene on the current semiconductor wafer scale.

Samsung is ready to point out this is great for wearables and flexible displays, but what they’re not telling us is that Graphene is a major component for future battery technology. Time and again, news pops up of a smartphone battery that can charge in 15 minutes and stays live for a week. A big part of that is Graphene, which allows for the exchange on electrons faster than a normal battery, charging it quickly. There is still no timeframe for when this could hit devices, much less retail, but it’s a major breakthrough for mass production. If you want more details on the process, Samsung notes their research will be published in today’s issue of Science Magazine and Science Express, which is downloadable.

Galaxy S5 Display is the Most Accurate and Best Performing Screen Ever Tested

Posted by Kellex March - 31 - 2014 - Monday Comments Off

Display expert and guru of all things pixel, Dr. Raymond M. Soneira of DisplayMate, released his latest shoot-out of top tier devices, this time focusing on the Samsung’s new Galaxy S5. As noted in his report, Soneira talks about Samsung’s move this year to not drastically bump up the display size or resolution and instead focus on viewing angles, display brightness, color accuracy, and power efficiency. In other words, fine-tuning their AMOLED technology was the goal.

How did they do? According to Soneira, the 5.1-inch FHD Super AMOLED display in the Galaxy S5 is the best display he has ever tested. 

Here are some of the highlights of his report:

  • Evolution of OLED Displays:  The Galaxy S4 and Note 3 both showed tremendous improvement in the OLED display category, but the Galaxy S5 brings a “major improvement” over both on a number of levels.
  • Best Smartphone Display:  The GS5 display is the best performing display that DisplayMate has ever tested. It set new records in performance for highest brightness, lowest reflectance, highest color accuracy, infinite contrast ratio, highest contrast rating in ambient light, and smallest brightness variation with viewing angle.
  • Highest Color Accuracy:  With the GS5 set to “Cinema Mode,” the device has the most accurate colors of any smartphone or tablet ever tested.
  • Brightness:  The Galaxy S5 is 22% brighter than the Galaxy S4 and 13% bright than the Galaxy Note 3. The GS5 also comes with a “Super Dimming Mode” for using the display in dark environments.
  • Power Efficiency:  The GS5 showed a 27% improvement in display power efficiency over the Galaxy S4.

I thought the display on the Galaxy Note 3 was the most beautiful display I had ever used, so after reading this report, I can tell you now that I cannot wait to get my hands on the Galaxy S5 for further testing. I’ve always been a fan of AMOLED displays, but if it is now topping charts of display gurus, I can’t imagine I’ll be in the minority with my love of this display type, even if Samsung is using a diamond pixel arrangement.

Quad HD vs 1080p displays: closeup comparison

Posted by wicked March - 19 - 2014 - Wednesday Comments Off

Find 7 2014 Hands on AA-1180658

The Find 7 launched today, and one of the its defining features is its ultra-sharp display.

The Find 7’s 5.5-inch IPS LCD display is made with low temperature polysilicon technology, using the Touch on Lens (ToL) technique, which enables a thinner design, higher shock resistance, and improved sensitivity to touch. But the most impressive specification of the device is definitely its resolution: the Oppo Find 7 is the first smartphone to launch internationally with a 2560 x 1440 display, also known as Quad HD or 1440p resolution.

Cramming 3,686,400 pixels on a 5.5-inch display makes possible a whopping 538 ppi pixel density, way above the previous record held by the HTC One, at 469 ppi.

Putting a Quad HD display on a smartphone is an impressive technical achievement, but we have to ask ourselves, are the returns worth the investment? Some argue that even Full HD (1920 x 1080, also known as 1080p) is overkill on a smartphone screen, so how about Quad HD ? Is it just an upgrade for the sake of upgrading or is it a true value adding improvement?

Oppo actually released another version of the Find 7, called Standard, which comes with a Full HD display of the same dimensions. We compare the two displays below to see how significant the difference between Quad HD and Full HD is.

Note: the devices we received from Oppo are pre-production units. Their displays have not been properly calibrated, so please disregard the color differences.

OPPO Find 7 features QHD display, 13 MP camera that can shoot 50 MP photos

Posted by wicked March - 19 - 2014 - Wednesday Comments Off

OPPO has just unveiled its latest masterpiece and it doesn’t disappoint, at least in as far as matching rumors to reality goes. The OPPO Find 7 boasts almost all the buzzworthy specs and features that you’d want to find in a high-end smartphone this year.

The size of the screen, which is confirmed to be at 5.5 inches, is almost all but known, though there was still some doubt about the resolution. Now OPPO has revealed that its display does boast of a Quad HD 2560×1440 resolution, giving the Find 7 a rather high pixel density 538 PPI. Of course, OPPO cannot lay claim to the first 2K display smartphone. Vivo had that last year with the Xplay3S, but perhaps now the world will be starting to pay attention. OPPO’s smartphone, however, is smaller and most probably easier to hold.

The OPPO Find 7 is no pushover either when it comes to raw power, as it is driven by Qualcomm’s most recent Snapdragon 801 processor, sporting higher clock speeds, at 2.5 GHz to be exact, and supporting faster LPDDR3 memory. Not only that, you also have a rather ample 3 GB of RAM, currently the maximum you’d find in mobile devices, as well as 32 GB of storage. The smartphone also features Rapid Charge technology. What this practically means is that you won’t need to stay tethered to a wall socket for a long time, as you can charge the 3000 mAh battery up to 75 percent in only 30 minutes, or so OPPO advertises.

But perhaps the star of the show, and also the most contentious, is the rear side camera. Before anything else, let it be known that it is only a 13 megapixel shooter, with Sony’s EXMOR IMX214 sensor. Where did all that talk about 50 megapixel cameras come from, you might ask. Apparently, the OPPO Find 7 is indeed capable of shooting 50 megapixel images. It does so using a combination of software and hardware tricks. Details are still fuzzy at the moment, but according to OPPO, the device takes 10 photos utilizing a Super Zoom feature which are then stitched up together to form one 50 megapixel image. The camera is also capable of shooting 4K videos, as well as 720p 120 fps videos for slow motion effects.

There is, however, also a lower-tier variant of the OPPO Find 7. This one sports a slower MSM8974AB clocked at 2.3 GHz. Though if you remember our little diversion into Snapdragon land, it can still be the upgraded Snapdragon 801. RAM has also been knocked down a notch at 2 GB, and internal storage is down to 16 GB.

OPPO has not yet announced the availability of the OPPO Find 7, nor if it has plans to make the device available in other markets. This latest high-end phablet is quite interesting, so we’re keeping our fingers crossed that OPPO officially brings it to the US as well. In China, the higher premium Find 7 version is priced at 3,498 CNY, roughly $564, while the standard edition has a price tag of 2,998 CNY, or around $483.

OnePlus One tipped to sport 5.5-inch screen in a 5-inch body

Posted by wicked March - 12 - 2014 - Wednesday Comments Off

Newcomer OnePlus has a slogan boasting that it will never settle for anything less, and now it seems that it applies to the laws of physics as well. Building up hype around its first ever smartphone, the company is now teasing the fact that the OnePlus will have a spacious 5.5-inch 1080p display crammed into a 5.0-inch frame.

To be clear, that photo above is the Sony Xperia Z1, which has a 5.0-inch screen. In the forum post that revealed this fact, CEO Pete Lau claims that the OnePlus One is actually lying beneath the Xperia Z1, completely eclipsed by the Sony smartphone. This implies that the upcoming device is even smaller than the 5.0-inch Xperia.

But despite that fact, the smartphone will still have a 5.5-inch display, with a 1080p resolution, at least that’s what leaks, rumors, and Lau’s implicit hint are saying. Some speculate that the device will barely have any bezel to make this possible, though that, of course, remains to be seen. It will definitely be an engineering feat worthy of praise if a company that didn’t even exist a few months ago manages to pull this off without unwanted side effects. But wait, there’s more! The screen will also feature Touch On Lens modules that practically eliminates the space between the touch sensor and the display itself, making touches more responsive and look more natural.

Given the leaks and rumors, which include a Qualcomm Snapdragon 800, 16 GB of storage, and a 3,100 mAh battery, which is unfortunately not removable, and of course, CyanogenMod right out of the box, the OnePlus One is shaping up to be an interesting device. We still have to wait for the real deal, which is expected to debut around March 16.

OPPO Find 7 teaser confirms multiple display resolutions

Posted by wicked March - 4 - 2014 - Tuesday Comments Off

There has been several official teasers from OPPO in amongst the numerous leaks and rumors surrounding the Find 7. One in particular arrived back towards the end of last year. That one confirmed the display size at 5.5-inches and with a resolution of 2560 x 1440. While that seemed to have been good enough news, later rumors began mentioning another handset, one with a 5.5-inch display and resolution of 1920 x 1080.

Details for the two handsets came by way of leaked AnTuTu benchmark reports. The reports were showing the devices as the x9007 and the x9077, with the higher resolution model being the latter. Regardless though, that left some questioning whether OPPO had plans to release two models of the Find 7. And well, it seems they will be doing just that.

A new image teaser has been shared by OPPO on the Chinese language Weibo. The image sits at the bottom of the post, however the key details include the mention of both display resolutions. It seems those leaked benchmarks were indeed accurate. Along with the display details, there was also a date of March 19th, which is when we are expecting to see the Find 7 get an official unveil.

Of course, the March 19th date comes more as confirmation than surprise. If you remember back, that date was tipped back in mid-February when another series of OPPO released teaser images surfaced. Anyway, March 19th is roughly two weeks from today and it looks like that is when the official and complete set of specs will finally be revealed.

For now, unconfirmed reports still point towards the handset as having a Snapdragon 800 processor with 3GB of RAM, 16GB of internal storage space, a 5MP front-facing camera, 13MP rear-facing camera and Android 4.3.

How Much of Your Phone is Actually the Screen?

How Much of Your Phone is Actually the Screen?



“Bigger screens and smaller bezels” have been the touted design mantra for most Android devices over the past few years, but how much screen are we actually getting? @somospostpc did a little bit of the number crunching for us and gives us the the percentage of space that the actual display takes up on the front of most of the top Android smartphones.

It is not a surprise that we see some of the latest and most highly regarded Android phones out right now have the largest percentages of display to bezel. While the LG G2 takes the top spot,  the Moto X, Galaxy S4, and Nexus 5 are all near the top in terms of display percentage.

How far do you think Android and Google can push this percentage?

LG G Flex initial US availability detailed

Posted by wicked January - 16 - 2014 - Thursday Comments Off

LG announced the upcoming US availability of the G Flex earlier in the month during CES. At the time LG mentioned the handset would be coming available during the first quarter of the year and with three of the four major US carriers. Those three included AT&T, T-Mobile and Sprint. And as we often see with these types of device announcements, LG basically left everyone waiting for the individual carrier announcements for the specifics.

lg-g-flex-02

Well, while this doesn’t necessarily mean we know which carrier will have the handset available first, Sprint has come out first with word of a release date and price. The carrier has said the LG G Flex pre-orders will begin today and the handset will be priced at $299.99. And just to clarify, that is a two-year agreement price. Aside from pre-orders, there are two other key dates to mention.

Details here point towards January 31st as the day the G Flex will arrive in Sprint sales channels. This includes business sales, telesales and online sales. The other date is February 7th, which is when the LG G Flex will first appear in the retail stores.

Also worth mentioning, those who move forward with a pre-order will get a free Quickwindow Folio Case, which regularly sells for $59.99. In terms of the phone itself, the LG G Flex sports a 6-inch HD curved P-OLED display with a resolution of 1280 x 720.

The handset is then powered by a 2.26GHz Qualcomm Snapdragon 800 processor with 2GB of RAM, 32GB of internal storage, 3500 mAh battery, 2.1 megapixel front-facing camera, 13 megapixel rear-facing camera and Android 4.2.2 Jelly Bean.

Another key aspect of the LG G Flex, aside from the flexible display, is the rear-button setup. The power button as well as the volume up/down buttons are sitting just below the camera lens. All that having been said, while the Sprint price doesn’t firm up anything in terms of the AT&T and T-Mobile pricing, it does give us a good point of reference.

LG G Flex display flexing may lead to bumps

Posted by wicked January - 16 - 2014 - Thursday Comments Off

LG recently announced the G Flex would be arriving with several US carriers. But even outside the US market, the handset is still relatively new. The LG G Flex is a smartphone that sports a 6-inch curved display. And as suggested by the name, the display is also flexible.

lg-g-flex-12

This doesn’t mean the handset can regularly change shape, but there is a bit of flex that should help to make the phone a bit more durable. To that point, LG has said they have tested the G Flex with 88 pounds of weight on the back panel. Furthermore, the handset has successfully completed a round of being “flattened out” 100 times without any physical damage.

We’ve been carrying an LG G Flex lately, and will have a full review here shortly, and while we checked out the ability to flatten out the handset, we haven’t seen any issues as a result. But that is not to say there isn’t something going on. Recent reports coming from the Korea Times brings talk of bumps on the display.

It was said these bumps come as a result of regular flexing of the display. LG did acknowledge the issue in a recent statement, but they do not seem overly concerned. There seems to be a bit lost in the translation, however the key piece of the statement is as follows;

“Because the G Flex components inside the glass cover, OLED display, battery are elastic, excessive or frequent force that flattens the device produce bumps.”

K2014011500251-450

LG did also go on to mention how these bumps will not affect the performance of the G Flex and that they should disappear over time. And as a warning, LG suggests G Flex users “don’t try to use frequent, excessive force on the device screen.” The image sitting above offers a look at the two bumps that have been appearing as a result of regular flexing.

As for the US release of the the LG G Flex, that is planned for the first quarter of the year and will include AT&T, T-Mobile and Sprint.
