Motorola currently assembling 400,000 Moto X phones each month

Motorola says they now assemble over 400,000 Moto X phones each month. The Moto X's display is a 4.7" 720p (316 ppi) AMOLED panel made by Samsung.

While these numbers aren't very high compared to Samsung's own sales (for example they made about 10 million GS4 phones a month when they launched) it is still good news for Motorola and their US factory (which is somewhat depressing still if you check the image above).

CPT shows an AMOLED based smart glass HMD

Taiwanese CPT is showing a new prototype smart glass HMD that uses an AMOLED microdisplay. This Google Glass like product is "ready to ship":

CPT is using a 0.5" 800x600 (SVGA) microdisplay with a display area of 10.13x7.61 mm. It simulates a 15" display from 2.5 meters. As far as I know OLighTEK (a Chinese-based OLED microdisplay maker) is the only company that ships 0.5" SVGA OLED microdisplays so it is likely that they are the display supplier. CPT is also developing AMOLED displays, but as far as I know they do not produce OLED microdisplays.

Google invests in LCoS maker Himax, probably means no OLED in next-gen Glass HMD

Himax just announced that Google bought a 6.3% stake in the company (in Himax Display Inc, to be exact, a daughter company of Himax Technologies). This money will be used to expand Himax's LCoS microdisplay capacity. Google also has an option to buy a further 8.5% of the company.

Himax's LCoS displays are used in Google's Glass HMD prototypes. A couple of months ago there were reports from Korea that Google are in talks with Samsung Display to supply OLED microdisplays for the next-gen Glass product (the first commercial one). I guess that this latest investment means that Google will keep Himax's products and will not opt for OLEDs. At least not for now...

Motorola confirms that the Moto X will sport an OLED display

We heard speculation about Motorola's upcoming "X" phone for a while now. Today Motorola's CEO Dennis Woodside confirmed that the company is developing a new flagship phone that will be called "Moto X". The Moto X will sport an OLED display and advanced sensors. Motorola wants to launch it in October 2013, and this will be the first phone designed after Google bough Motorola.

One of the key features of this new phone will be the low power consumption. It will include two processors, and I assume that it will use a Super AMOLED Advanced display - which use red and reen phosphorescent emitters to cut the power consumption by 25% compared to normal Super AMOLED displays (except for the one used in the GS4). Motorola already uses these panels (or regular Super AMOLED ones) in several of their mobile phones, including the relatively new RAZR i, RAZR HD and RAZR M.

Samsung Display did develop an OLED microdisplay, back in 2011

Two days ago we reported on rumors that Google's next gen Google Glass HMD (or "wearable computer") will use OLED microdisplays made by Samsung Display. I wrote that as far as I know SDC never developed OLED microdisplays, but apparently I was wrong.

One of my sources sent me a conference paper from 2011 describing a 0.6" XGA OLED microdisplay - made by Samsung Mobile Display. The OLED-on-silicon device (Samsung calls them OLEDoS) used white OLEDs with color filters (all OLED displays made today use this architecture, although makers are moving towards direct emission). I don't think Samsung ever produced such displays, but apparently they did make some successful prototypes.

Google to use OLED panels in its next-gen Google Glass HMDs?

Update: turns out that I was wrong and Samsung did develop an OLED microdisplay, an XGA one back in 2011

The Korea Times claims that Google's next gen Google Glass HMD (or "wearable computer") will use OLED microdisplays made by Samsung Display. Or at least SDC made a proposal for Google to replace the current LCoS panels by its OLED displays. The current Google Glass prototypes use Himax' LCoS displays.

At SID 2013, SDC's CEO did mention OLED microdisplays on silicon during his keynote speech. He also says that these kinds of displays may be used for augmented-reality devices such as Google Glass. Last month Google's CEO Larry Page visited Samsung's OLED facilities, and apparently Page is "interested in Samsung's OLED business". So now the rumors are that Google are interested in small sized OLED displays.

Will Google and Samsung partner on OLED TVs?

Google's CEO Larry Page visited Samsung's OLED facilities, and apparently Page is "interested in Samsung's OLED business". According to some reports, the two companies may discuss a partnership on OLED TV panels, perhaps akin to Google's collaboration with LG on Google TV. Or it might be that Google are interested in introducing their own branded TV set, but I don't think it's likely they'll go for highly expensive OLED panels yet.

Samsung is already providing OLED panels to several Android smartphones, including ones made by Google's Motorola Mobility. Some reports suggest that Motorola's upcoming device, code named Google X, will sport an unbreakable OLED display. Google themselves has filed for several patents involving OLED technology (or actually software tailored for OLED panels).

Google's new patent describes a power saving technique for mobile devices with OLED displays

Google was granted a new patent (filed in July 2013) that describes a technique for saving power on mobile devices with OLED displays. Basically the idea is that the when battery is low, the system can change the display characteristics (lower the resolution, disable animation and use red and black colors only). You can see the basic schema from the chart below, which is actually quite badly written: there's no option for a normal mode, and there's just one check and no loop as there should have been. Oh well...

This patent is only useful and valid for OLED displays. I'm not sure how canceling blur and animation actually conserve power on OLEDs. Showing just red and black colors make sense, and reducing the resolution also makes sense if they mean showing a small image with black around it. In September 2012 Google were granted a patent in which they suggest to reduce the image on a screen when the device is idle - this is basically the same idea which relies on the fact that black pixels on OLED displays do not draw power.

Will the upcoming Google/Motorola phone sport an unbreakable display?

During Google's financial results conference call, the company's CEO Larry Page discussed the opportunities in mobile phones. The company bought Motorola Mobility and is expected to release new phones with new technology soon. Page hinted at unbreakable phones ("when you drop your phone, it shouldn't go splat") and said that battery life is still a huge issue. Hopefully Motorola will indeed incorporate unbreakable plastic-based OLED panels in their upcoming device (some say it'll be called Google X).

Motorola already uses OLED panels in several of their mobile phones, including the relatively new RAZR i, RAZR HD and RAZR M. Most of these Motorola's OLED phone sport Super AMOLED Advanced displays, which are 25% more power efficient compared to other OLEDs (according to Motorola's marketing, anyway). This is probably due to the fact that Motorola's displays are one of the few Samsung OLEDs that use green phosphorescent emitters, and may be the reasoning behind Page's "battery life" comment.

Google's new phone and tablet use LCD displays, not OLED ones

Google unveiled their new tablet (the Nexus 10, made by Samsung) and phone (the Nexus 4, made by LG) - and both use LCDs (yeah, those OLED rumors were incorrect after all). The Nexus 10 uses a 10", 2560x1600 (300 ppi) "True RGB Real Stripe PLS" display (PLS stands for Plane to Line Switching, a Samsung-developed tech which is supposed to be brighter and with better viewing angles than IPS panels).

The Nexus 4 uses a 4.7" 1280x768 IPS display (probably made by LG Display). This is the first Google Nexus phone that does not have an AMOLED display. What a shame.
