The Most Color Accurate Mobile Display


Dr. Raymond Soneira conducted a study to find the most color accurate mobile display. He tested the six best mobile displays from DisplayMate’s Display Technology Shoot-Out article series over the last year: Samsung Galaxy Note 4, Microsoft Surface Pro 3, Samsung Galaxy Tab S 10.5, Amazon Kindle Fire HDX 8.9, Apple iPhone 6 Plus, and Apple iPad Air 2. The results… were in that order, with the Samsung Galaxy Note 4 in Basic Screen Mode coming out on top.





WALTR: Natively Playback Any Video File On iPhone, iPad


I test drove WALTR, and it is awesome. I had an AVI movie file, and normally there is no easy way to play it on my iPad. Here’s the hard way:

Here’s the easy way:

To watch the video on my iPad all I need to launch is the built-in Videos app. WALTR can playback a lot of video formats: MP4, AVI, M4V, M4A, FLAC, WMA, etc. Get it.





AT&T Stops Using Undeletable Phone Tracking IDs; Verizon Continues


Julia Angwin, ProPublica:

AT&T says it has stopped its controversial practice of adding a hidden, undeletable tracking number to its mobile customers’ Internet activity.

Why would AT&T do this?

The tracking numbers can be used by sites to build a dossier about a person’s behavior on mobile devices – including which apps they use, what sites they visit and for how long.

Ah, to sell user data to advertisers.

Edmonds said AT&T may still launch a program to sell data collected by its tracking number, but that if and when it does, “customers will be able to opt out of the ad program and not have the numeric code inserted on their device.”

If AT&T is more interested in its customers than its advertisers — that’s a big if — wouldn’t it be better for AT&T to make the sale of your mobile activity data opt in, instead of opt out? And what about Verizon?

A Verizon spokeswoman says its tracking program is still continuing, but added “as with any program, we’re constantly evaluating.”

Verizon uses the tracking number to identify the users’ behavior and offer advertisers insights about users gleaned from that data. Verizon says the data it sells is not tied to a users’ identity.

Verizon does not seem to give a hoot about its customers. Something to think about: identifying a user with a single data point is difficult, but as you add more data points uncovering the identity of a user becomes easier. I’m relieved that I am not an AT&T or a Verizon customer.





Microsoft Office Free on Mobile Platforms


Microsoft Office is free on iOS and Android. At first I was excited, went to the app store, searched for Microsoft Office, and then almost downloaded the free apps. Almost. I realized I didn’t need Microsoft Office. I haven’t used Word, PowerPoint, and Excel in years. And I hope I never have to.





Which Messaging Technologies Are Truly Safe And Secure?


Electronic Frontier Foundation (EFF):

The scorecard includes more than three dozen tools, including chat clients, text messaging apps, email applications, and technologies for voice and video calls. EFF examined them on seven factors, like whether the message is encrypted both in-transit and at the provider level, and if the code is audited and open to independent review. Six of these tools scored all seven stars, including ChatSecure, CryptoCat, Signal/Redphone, Silent Phone, Silent Text, and TextSecure. Apple’s iMessage and FaceTime products stood out as the best of the mass-market options, although neither currently provides complete protection against sophisticated, targeted forms of surveillance. Many options—including Google, Facebook, and Apple’s email products, Yahoo’s web and mobile chat, Secret, and WhatsApp—lack the end-to-end encryption that is necessary to protect against disclosure by the service provider. Several major messaging platforms, like QQ, Mxit, and the desktop version of Yahoo Messenger, have no encryption at all.

I’m going to try out some of these.





Nexus 9: Review by The Verge


Nexus_9

Dan Seifert, The Verge:

The Nexus 9’s display might have the same resolution and aspect ratio as the iPad, but it’s not nearly as nice a screen. Colors aren’t as vibrant or appealing, the screen isn’t laminated to the glass as on the iPad Air 2, and the backlight bleeds into the edges of the screen in unsightly ways. It’s not a bad display by any means, but it feels appropriate for a $250 tablet, not something that starts at $400.

The display on the iPad Air 2 is now laminated unto the cover glass. The competition has moved forward. (Though the new iPad mini 3 continues to have an air gap between the two.) Once you get exposed to something better — like content seemingly right at your fingertips on a tablet — that becomes the new thing to beat, and the Nexus 9 falls short. So does the iPad mini 3.

Light leakage should be a thing of the past and it is disappointing to see manufacturers continuing to struggle with this, especially on a halo product like the Nexus 9. Perhaps replacing double sided tape with an adhesive to attach the backlight unit, which is what LG Display did with its slim bezel 5.3-inch LCD, would help.





LG Display: 0.7mm Bezel Full HD LCD Smartphone Panel


LG Display:

To realize the 0.7mm bezel width on the left and right sides of the panel, which is narrower than the 0.8mm thickness of a credit card, LG Display used its “Neo Edge” module processing technology and the world’s first “Advanced In-Cell Touch (AIT)” technology.

LG Display’s Neo Edge technology uses an adhesive instead of double-sided tape to attach and completely seal the total area and edges of the panel’s circuit board and backlight unit. Because there is no plastic guide panel to attach the panel and backlight, the Neo Edge technology helps achieve minimal bezel width, while blocking light leakage and being waterproof and dustproof.

The adhesive seal also prevents corrosion that sometimes occurs along the edge of the glass panel when double-sided tape is used, while dramatically improving the panel’s durability despite the narrow bezel because of increased elasticity as the adhesive hardens.

The company’s AIT technology, exclusively developed by LG Display, reduces the need for bezel space because the touch panel is embedded into the LCD module. The technology offers a slim design and excellent touch, while saving costs since a separate process for touch functions is not required.

Narrow left and right bezels, no light leakage, waterproof, dustproof, more durable, and costs less. What’s not to like.

I am assuming this thin bezel 5.3-inch LCD panel is targeting high-end smartphones, so the only thing I would like to see is a bump in pixel format from 1920×1080 to 2560×1440.





Apple Watch: It Woke Me By Tapping My Wrist


Nellie Bowles and Dawn Chmielewski, Re/code:

“Just yesterday, somebody was saying, ‘Wow, do you know what I just did? I set the alarm in the morning, and it woke just me by tapping my wrist. It didn’t wake my wife or my baby,’” he recounted. “Isn’t that fantastic?”

That is Jony Ive talking. Fantastic? Yes, but I don’t see how this is possible. I was under the impression Apple Watch had a battery life that required nightly charging. Tim Cook on battery life, New York Times:

We think that based on our experience of wearing these that the usage of them will be really significant throughout the day. So we think you’ll want to charge them every night, similar to what a lot of people do with their phone.

The only possibility of this anecdote being true is that this somebody Ive is referring to had two Apple Watches: one for during the day and the other for wearing at night. With a battery life similar to that of today’s smartphones there is no way to wear Apple Watch during the day and continue to have it on while you are sleeping. The only way to wear Apple Watch while sleeping is to take it off and charge it during the day. Unless you are more interested in Apple Watch tapping your wrist to wake you up, I don’t see anyone regularly experiencing being woken up by her Apple Watch this way.





iPad Air 2: Review by Raymond Soneira


Raymond Soneira:

A major innovation for the iPad Air 2 (that is not fully appreciated) is an anti-reflection coating on the cover glass that reduces ambient light reflections by about 3:1 over most other Tablets and Smartphones (including the previous iPads), and about 2:1 over all of the very best competing Tablets and Smartphones (including the new iPhone 6). We measured a 62 percent decrease in reflected light glare compared to the previous iPads (Apple claims 56 percent) and agree with Apple’s claim that the iPad Air 2 is “the least reflective display of any Tablet in the world” – both are in fact understatements. While everyone has been in situations where it is difficult or even impossible to see the screen in very bright ambient lighting, where this obviously helps, it turns out that even in moderate indoor lighting the image contrast and colors are being noticeably washed out from reflections as well. For example, the Color Gamut is typically reduced by 20 percent even at only 500 lux indoor lighting. To visually compare the difference for yourself, hold two Tablets or Smartphones side-by-side and turn off the displays so you just see the reflections. The iPad Air 2 is dramatically darker than any other existing Tablet or Smartphone. Those reflections are still there when you turn them on, and the brighter the ambient light the brighter the reflections. It’s a major innovation and a big deal with visually obvious benefits!!

Some iPad Air 2 reviews have mentioned not experiencing a noticeable difference in ambient light reflections. Maybe reflections were so bad in the previous model a 56 to 62 percent decrease is still not very good. I look forward to the day when the experience of using smartphones and tablets outside in direct sunlight will be similar to using devices with E Ink displays.

The iPad Air 2 is the first iPad with an optically bonded cover glass – all previous iPad models had high reflectance air gaps under the cover glass – but they are simply catching up because almost all other leading Tablets have had a bonded cover glass without an air gap for years. One minor but noticeable issue is that the screen Reflectance spectrum is heavily weighted towards blue, which is may be noticeable for dark images or in bright ambient light.

This took a while.

However, other than the new anti-reflection coating and bonded cover glass, the display on the iPad Air 2 is essentially unchanged and identical in performance to the iPad 4 introduced in 2012, and is actually slightly lower in performance than the original iPad Air (for example 8% lower Brightness and 16% lower display Power Efficiency) – most likely the result of an obsession with producing a thinner Tablet forcing compromises in the LCD backlight.

Much more significant is that the iPad Air 2 does Not have the same high performance display technology enhancements that we measured for the new iPhone 6 and iPhone 6 Plus, which we rated the best performing Smartphone LCD Display that we have ever tested. While the iPad Air 2 has an all around Very Good Top Tier display, and most buyers will be happy with its performance, the displays on the Amazon, Google, Microsoft and Samsung Tablets that we have tested (see below) have better display performance in Absolute Color Accuracy, Brightness, Contrast Ratio, Viewing Angle, and Power Efficiency. However, the iPad Air 2 matches or breaks new records in Tablet (and Smartphone) display performance for: the most accurate (pure logarithmic power-law) Intensity Scale and Gamma, most accurate Image Contrast, (by far) the Lowest Screen Reflectance, and the Highest Contrast Rating for Ambient Light.

Apple is actively encouraging taking photos with iPads. One of the biggest knock on smartphones using OLED displays have been, not anymore, blown out over-saturated colors. Put it another way, we want and appreciate accurate colors on our photographs. I can understand the iPad Air 2 not being equal to the iPhone 6 and 6 Plus when it comes to color accuracy, since iPhones are used far more for taking photos than iPads, but for the iPad Air 2 to be less accurate than tablets from Amazon, Google, Microsoft, and Samsung is disappointing.
