Panasonic Develops IPS Panel with 1,000,000:1 Contrast Ratio, 1000 Nits Brightness

Panasonic Develops IPS Panel with 1,000,000:1 Contrast Ratio, 1000 Nits Brightness

Panasonic has developed a new type of IPS liquid crystal panel that has a 1,000,000:1 contrast ratio, as well as a peak brightness of up to 1000 nits. Many LCD displays often advertise such contrast ratios which are measured against a dynamic backlight and are essentially meaningless, but in this case Panasonic is talking about the static contrast ratio of the display, which only reaches as high as 2000:1 on a typical IPS display. Little information is available about the technology at this point, but Panasonic claims that it is achieved by implementing pixel-by-pixel control of backlight intensity and that panels featuring the tech can be produced using contemporary LCD manufacturing facilities.

One of the key advantages that OLED displays have over LCD displays is extremely high contrast ratio that results in superior blacks. The reason why OLEDs can display deeper blacks is simple: such panels do not use backlighting and can completely switch pixels off when they need to display blacks. By contrast, LCDs use backlighting that cannot be turned off on a pixel-by-pixel basis, which is why in many cases blacks look like dark greys.

In the most optimal case, an LCD display will use full-array backlighting, where there are several LEDs placed directly behind the liquid crystal layer. This allows for a degree of control by performing local dimming of certain areas, which is how LCD televisions have managed to meet the standards required for HDR certification. However, the precision of the backlight control is not close to that of an OLED display which works at the pixel level. Even more common, especially in monitors and less expensive televisions, is the use of edge lighting where LEDs are placed along the edges of the display and the light is distributed across the panel using a guiding plate, which means you can really only control the overall brightness across the entire display.

As it appears, Panasonic has found a way to substantially increase contrast ratio of IPS LCDs using a high-brightness backlight and a special layer of light-modulating cells that enable pixel-by-pixel control of backlight intensity. These cells are made of light-tolerant liquid crystal material that has different light-transmission properties compared to those used in the display cells. The layer of light-modulating cells is placed between the backlight and the LCD cells and thus can control light leakage. At a high level, one could think of them like gates placed behind each pixel on the display.

Panasonic does not reveal many details about its light-modulating cells, but since it uses the term “cells”, it clearly indicates that we are dealing with a relatively thick layer of liquid crystals, not a thin layer of quantum dots (you can see an illustration from Nanosys (a company that produces quantum dot films that are currently used on Samsung TVs and displays) to compare “cells” versus “quantum dots”).

Usage of a high-brightness backlight and a layer of light-modulating cells enable Panasonic to build display panels with up to 1000 nits brightness as well as a static contrast ratio of 1,000,000:1. These figures mean that a black level of 0.001 nits should be possible, which is well beyond what even the best full-array backlit LCD displays can offer today.

Panasonic claims that the addition of the layer can be done using the existing equipment for LCD manufacturing, but it’s not clear how costly the technology will be to implement or if it requires further components to be added to the LCD stack. The company plans to offer displays featuring the new technology for various professional applications, such as video production, medical, automotive, engineering and so on. Given the positioning, it is obvious that the price of IPS displays with enhanced contrast will be well above that of mainstream monitors.

Panasonic intends to start sample shipments of its new monitors in January, 2017, so the commercialization of the technology will not be too far off.

Seagate Revives Maxtor Brand for External Storage

Seagate Revives Maxtor Brand for External Storage

UPDATE 12/1 9AM: Seagate confirmed Thursday that it decided to revive the Maxtor brand in a bid to sell value products. In the coming months the company plans to phase-out its inexpensive Samsung-branded products and Maxtor will take their place.

Seagate has quietly started to sell Maxtor-branded external storage devices in various countries. At present, the company offers the Maxtor M3 and the Maxtor D3 Station DAS devices, which it also sells under the Samsung name (yes, you read that right – click here for proof). Right now, it is unclear for how long Seagate plans to use the trademark, which it has not touched for quite a while.

Maxtor was a major maker of hard drives that was founded in 1982 and acquired by Seagate in 2006. In the early 2000s, Maxtor was the largest maker of HDDs in the world after its acquisition of HDD division from Quantum, but its advantages somewhat diminished by the middle of the decade due to various reasons, such as the lack of a comprehensive lineup of 2.5” hard drives in the product stack. Maxtor faced severe financial troubles for the most part of its history, and after it was acquired it was also plagued by quality problems as well as controversial management decisions. After Seagate took the company over in 2006, it did ship Maxtor-branded internal and external drives for a couple of years (in fact, external storage was a strong side of Maxtor), but eventually the trademark was dropped.

Earlier this year Seagate decided to start using the Maxtor brand again to sell its M3 and D3 Station external storage products. Both of the DAS devices are also known as the Samsung M3 as well as the Samsung D3 Station which are available worldwide today. In fact, it is surprising to see that Seagate still uses the Samsung brand for hard drive products about five years after the acquisition of Samsung’s HDD business. Under the initial agreement, Seagate had rights to use the Samsung trademark for hard drives for 12 months following the buyout. Apparently, the two companies have amended the initial agreement as Seagate currently offers four Samsung-branded products for consumers. Meanwhile, the revival of the Maxtor brand could indicate that Seagate has begun to phase-out use of the Samsung trademark for its products, which is why it creates alternatives featuring a different brand (some may say that we are dealing with a plain re-badging).

3 TB STSHX-D301TDBM
4 TB STSHX-D401TDBM
5 TB STSHX-D501TDBM

The Maxtor M3 external drive offers 500 GB, 1 TB, 2 TB and 4 TB capacities via a USB 3.0 interface. The top of the range Maxtor M3 model is based on the Spinpoint M10P 2.5”/15 mm HDD with five 800 GB platters featuring shingled magnetic recording technology at 5400 RPM spindle speed as well as 16 MB of cache. In the meantime, models with lower capacities use different hard drives and have smaller dimensions. The DAS comes with AutoBackup and SafetyKey software for automatic backup and protection.

The Maxtor D3 Station uses two 2.5” HDDs to offer 2 TB, 3 TB, 4 TB and 5 TB capacities (as opposed to up to 6 TB offered by the Samsung D3 Station version). Just like the M3, the DAS uses a USB 3.0 interface both for data transfer and for power. In addition it also comes with AutoBackup and SafetyKey. Since the D3 Station is designed to serve essential storage needs, it is basically a JBOD device that does not offer any kind of RAID for additional performance or reliability (it also makes for an inconsistent performance profile).

At present, Seagate uses its own brand to sell various external storage devices, the LaCie trademark for premium DAS products and the Samsung brand for select inexpensive external storage solutions. On Thursday the company said that it plans to continue using three brands for its external storage devices going forward with Maxtor taking the the place of Samsung. Seagate intends to add more products into the Maxtor lineup when it makes sense. The statement by Seagate reads as follows.

“Seagate’s consumer strategy is to have three brands to serve our customers varied external storage needs. Seagate (mainstream), LaCie (premium/creative pro) and Maxtor (value),” the company indicated. “The Samsung external HDD line is indeed being transitioned to the revived Maxtor brand. We will continue to provide products under the Maxtor brand and evolve the line as it makes sense.”

At present, the Maxtor M3 and the Maxtor D3 Station products are available at Amazon and multiple other online and retail stores across the world.

Meizu Launches the PRO 6 Plus: 5.7-inch SAMOLED and Exynos 8890 SoC

Meizu Launches the PRO 6 Plus: 5.7-inch SAMOLED and Exynos 8890 SoC

Meizu added a new flagship phablet to its smartphone lineup today. The new 5.7-inch PRO 6 Plus is the direct successor to the PRO 5, but it incorporates the updated styling from the smaller 5.2-inch PRO 6. On paper at least, the PRO 6 Plus appears to be a definitive upgrade relative to Meizu’s previously released phones, unlike the PRO 6 which trailed the older PRO 5 in performance, battery life, and audio quality and failed to separate itself from the similar but less-expensive MX6.

The PRO 6 Plus incorporates the same aluminum unibody construction and elegant styling as the PRO 6. The slightly raised, circular camera surround with Meizu’s circular, dual-tone LED flash ring below give the back of the PRO 6 Plus a distinct look. The plastic antenna strips are colored to better match the sandblasted aluminum chassis and stick close to the upper and lower edges to further minimize their appearance. Its rounded edges and radiused corners make it comfortable to hold, although its smooth finish makes it feel a bit slippery. The 2.5D edge-to-edge glass covering the front eliminates sharp edges, enhancing the smooth feel of the phone.

What separates the design of the PRO 6 and PRO 6 Plus from so many other metal unibody phones, however, is Meizu’s attention to detail. Every edge and hole—the camera surround, ring flash, speaker holes—has a polished chamfer, and the single piece volume rocker and power button near the top of the right edge are inset into a polished groove. All of these extra machining features give the PRO 6 phones a premium look and feel.

Launch OS Android 6.0 with Meizu FlymeOS 5.2 Android 6.1 with Meizu FlymeOS 6

The Meizu PRO 6 Plus, like the PRO 5 before it, uses a 5.7-inch SAMOLED display from Samsung; however, resolution increases to 2560×1440, which is a vast improvement over the PRO 5’s 1080p panel whose pixel density was insufficient to overcome the limitations of its PenTile subpixel arrangement. The display’s brightness ranges from 3 nits to 430 nits in direct sunlight when using the auto-brightness boost feature, according to Meizu. Although an APL value was not specified, I assume these are for 100% APL based on our measurements of the PRO 6, which achieves 436 nits at 100% APL and 512 nits at 50% APL.

Meizu also claims 103% coverage of the NTSC color gamut, which is good news for people who prefer highly saturated, vivid colors. Meizu introduced several different screen modes, including a proper sRGB mode, in FlymeOS 5.2, along with a color temperature slider, to allow for some adjustment of the display’s output, although it’s unclear if these features carry over to FlymeOS 6.

Most phones are now incorporating special night modes that filter out blue light for nighttime reading or low-light situations, and the PRO 6 Plus is no exception. It’s also the first Meizu phone to come with an always-on display (AOD) that shows the time, date, battery level, and notifications when the phone is locked. If enabled, Meizu claims it only consumes 1% of the battery’s charge per hour.

Inside the PRO 6 Plus is an Exynos 8890 SoC. Meizu has used Samsung’s Exynos chips in previous phones, most recently the Exynos 7420 in the PRO 5, and with Snapdragon 820/821 off the table because of its ongoing licensing disagreement with Qualcomm, the Exynos 8890 is a logical choice. The octa-core CPU uses a big.LITTLE pairing of four low-power ARM Cortex-A53 cores and four higher-performance, custom Exynos M1 cores from Samsung. Core frequencies vary depending on which storage option is selected. The version with 64GB of UFS 2.0 NAND uses a lower-binned SoC that limits the peak frequency of the Exynos M1 cores to 2.0GHz and the A53 cores to 1.5GHz, while the version with 128GB of internal storage allows the A53 cores to run at 1.6GHz and the M1 cores to run at up to 2.3GHz when three to four cores are active or 2.6GHz for better single-threaded performance when only one or two cores are active. Both versions use an ARM Mali-T880 GPU and come with 4GB of LPDDR4 RAM, but the lower-binned SoC only includes ten cores instead of the Exynos 8890’s usual twelve like in the 128GB version. While the amount of internal storage is reasonable, there’s no microSD support for storage expansion.

The PRO 6 Plus’ 3400mAh battery is a little on the small side given its size. Huawei’s 5.9-inch Mate 9 comes with a 4000mAh battery, for example. Even several smaller 5.5-inch phones such as Samsung’s Galaxy S7 edge (3600mAh), Xiaomi’s Redmi Note 3 Pro (4050mAh), and Meizu’s own M3 note (4100mAh) come with larger batteries. Meizu clearly prioritized thickness and weight over battery capacity, but we’ll have to wait and see how it performs in our battery tests before we can assess the impact of this decision. Regardless of how long the battery lasts, it should charge quickly thanks to Meizu’s mCharge fast charging technology that pulls up to 24W (8V/3A) at the wall.

Around back is a 12MP camera based on Sony’s IMX386 Exmor RS sensor with 1.25µm pixels. It employs a hybrid autofocus system that combines the benefits of phase detection (PDAF), laser, and contrast methods. The PRO 6 Plus also includes 4-axis optical image stabilization (OIS), a first for Meizu, which should help improve low-light photography by allowing sharp exposures up to 0.25 seconds. Covering the camera sensor is a 6-element lens array with f/2.0 aperture. Meizu also says its improved image-enhancing algorithms and noise processing take full advantage of Samsung’s integrated ISP.

One of the PRO 5’s best features was its excellent sounding audio subsystem. The PRO 6 took a more traditional approach and its results were disappointing by comparison. Fortunately, the PRO 6 Plus uses the same ESS Technology es9018k2m SABRE32 DAC as the PRO 5, which supports 16/24-bit audio from 44.1kHz to 192kHz with a dynamic range of 127dB and low noise. It also includes a dual-channel AD45275 power amplifier from Analog Devices.

The PRO 6 Plus comes with a touch-based, capacitive fingerprint scanner integrated into the front-mounted home button along with Meizu’s pressure sensitive screen technology it calls 3D Press, which the PRO 6 and PRO 6s also include. Because the software API’s are proprietary, the ability to press an icon on the home screen and open a shortcut menu or press on a hyperlink, email, or text message to open a preview are generally limited to Meizu’s apps.

In addition to 3D Press support, Meizu’s new FlymeOS 6 includes more than 400 new features, including the “One Mind” artificial intelligence engine that optimizes system performance by monitoring how the phone is used and prioritizes resources to the most used apps.

The PRO 6 Plus is available in three different colors: gold, gray, and silver. The gold and silver colors come with a white front, while the darker gray color comes with a black front. You can also choose between 64GB (¥2,999) or 128GB (¥3,299) of internal storage. The integrated Samsung Category 12 LTE modem supports 5-mode operation (no CDMA) and the following frequency bands (no LTE support in the US): FDD-LTE B1 / B3 / B7, TDD-LTE B38 / B39 / B40 / B41, WCDMA B1 / B2 / B5 / B8, TD-CDMA B34 / B39, GSM 850 / 900 / 1800 / 1900 MHz. It will be available in many Asian and European countries in December.
