Samsung to produce 7" high-res AMOLED display | SammyHub.com

Un écran tactile AMOLED 7″ à « forte » résolution chez Samsung | Le Journal du Geek

My comments

Samsung have been involved in developing the active-matrix OLED display over a long time and have refined it in to a single-layer AMOLED touchscreen display that is pitched at smartphones.

As you all will know, the difference between the OLED display and the LCD display is that the way the display is lit up. An OLED display uses power to actually light up the pixels rather than dynamically passing light through a filter that makes up the image, a practice that is done with LCDs.

There are some key benefits that these displays have such as high contrast, improved colour, a wide viewing angle as well as energy saving due to only needing to light up what is needed on the display. Infact I have described the OLED display as a “vacuum fluorescent display” for battery-operated devices because the displays have that same bright and crisp display characteristic as the vacuum-fluorescent displays used on a large range of good-quality consumer electronics like DVD players and home-theatre receivers.

For that matter, I currently own the Samsung Galaxy S Android smartphone which has this display technology and have been pleased with the way it handles regular display activity including pictures and videos. This is even after I have owned the Nokia N85 Symbian S60 smartphone which uses the same AMOLED display technology in a non-touchscreen application.

Now they have taken this technology further by developing the Super AMOLED Plus which is the same AMOLED display with integrated capacitive touchscreen as used in these Galaxy S series smartphones, but as a 7” 1024×768 variety.

At the moment, the obvious application for this display would be the 7” tablet but I would see it appeal to more applications such as dashboard touchscreens for the car or boat. This may also include the double-DIN multifunction head units that will appeal to the young males who want to equip their cars with street-worthy sound systems.

If Samsung wanted to have sufficient manufacture quantities for these displays as they do for the small OLED displays used in the smartphones, they would have to build one of their Galaxy Tab 7” tablets with these displays. This also includes encouraging other manufacturers to implement them in a 7” tablet model.

Who knows when it would be that Samsung would take the integrated touchscreen AMOLED display technology up to the 10” size for the larger tablets and netbooks.

Basic comments about Windows 8’s touch screen user-interface

A key user-interface concept in the next version of Windows will be a “Start Screen” that looks like a cross between Windows Phone 7’s home screen and the Windows Media Center interface. Here, this dashboard will have “Live Tiles” which present always-updated information in the window panes.

The applications represented on the “Live Tiles” can be a fully-fledged Windows application or a HTML5/JavaScript “mobile-like” app that links to a Web resource. This is taken further with Internet Explorer 10 implementing this functionality.

There will be the full integrated support for tablet computers and similar devices with an interface that works best with these devices as well as a regular keyboard / mouse interface. One issue that may affect software developers is that they may have to work the software so it can behave properly with a “no-keyboard” interface as well as a “keyboard” interface. Of course, the touchscreen keyboard interface will support a split layout so that the user can work the keys with their thumbs.

For some programs that primarily use mouse interaction like strategy or puzzle games, there won’t need to be much work done on having the programs work between a keyboard interface or a touch interface. But on the other hand, programs that rely on text entry such as email, the program may have to work with remapping the user interface to permit use of the virtual keyboard interfaces.

But where could this all lead to when it comes to the design of Windows-based computers?

Ever since Windows allowed for “tablet-style” computing with the Windows XP Tablet PC Edition, where the computer is operated using a stylus rather than by touch, there have been two form factors put forward to the market. One was the “slate” form factor which is like the tablet computers such as the iPad, where there isn’t a keyboard but the computer could work with a USB-connected keyboard; and the other was a “convertible” notebook computer with a screen that swivelled 180 degrees and folded flat to become a stylus-operated PC. There have been a few touchscreen variants of these form factors released subsequently once Windows Vista provided the touchscreen interface option.

The “slate” or “tablet” form factor could exist as an alternative to the iPad and Android-based tablet computers; and they could allow for operation with small keyboards for word-processing and emailing. But the computer press have forgotten about the “convertible” notebook form factor which has seen some resurgence with some manufacturers running with “netvertibles” – netbooks that have a touchscreen which can swivel between a traditional layout and a tablet layout.

Windows 8 vs the Apple platforms.

Another article had raised issues about Windows 8 becoming a competitor for a subsequent version of Apple’s iOS platform, especially the iPad implementation.

But they also raised the spectre of it competing with the next version of MacOS X, known as “Lion”. The main factor about this is that Apple were viewing the MacOS platform as a “horizontal” platform and the iOS platform as a “vertical” platform; with scant mention of any touch-enabled Macintosh computers coming on the scene.

The possibility of a granular touch-based computer marketplace

What I would see with these touch-based operating systems is the ability for hardware manufacturers to provide a granular marketplace for touch-based computing devices. This means that there could be a touch-based computing device that could suit particular users’ needs and budgets.

It would range from the 7” coat-pocket tablets serving as an alternative to a dedicated ebook reader through 10” tablets like the iPad fulfilling most general-purpose “dedicated-tablet” needs to 13”-14” convertible notebooks appealing to those of us who do plenty of emailing, word-processing or similar work on the road.

Of course, the operating environments for units that are 10” or above will differ across the marketplace in a similar way to what is happening with the smartphones. Here, users may place emphasis on factors like software availability, operating-system flexibility, battery runtime and system performance as they choose the operating environment.

Conclusion

The proposed Windows 8 environment could then become a game change when it comes to the touch-based computing environment.

Fujitsu Lifebook TH700 brings convertible tablet magic at a more affordable price — Engadget

My comments

I had previously mentioned in this blog about a “netvertible” computer design which is a netbook with a touch screen that swivels, being considered an affordable Windows-based alternative to the Apple iPad.

Just lately, Fujitsu have upped the ante with a convertible subnotebook / ultraportable computer that has a “convertible” touchscreen design and have pitched it at a more affordable price. This is showing that the convertible touchscreen is appearing in the netbook and subnotebook / ultraportable classes of Windows-based portable computers which represent affordable implementations of this technology and as the cost to integrate a touchscreen into a laptop-class computer reduces, more of the computers in this class will end up with a swivel-head “convertible” design for a significantly-reduced premium.

Now, the only step that needs to happen for them to convincingly make Apple take notice would be to see e-publishing platforms that are used with the iPad be available for the Windows 7 platform. This is so that publishers can achieve the goal of “e-books”, “e-newspapers” and similar publications in a “design once, view anywhere” manner with their rights protected.

As a blog writer, I would like to see a heterogenous environment exist for tablet-based e-publishing that allows for innovation, competition and affordably-priced user-improvable equipment.

My comments

There have been a few features that impressed me about the Cisco Cius Android tablet judging from the news articles that I have read. One was that the tablet was able to work as a fully-fledged Android tablet with access to the Android Marketplace in a manner that makes it compete with the Apple iPad. The other one was that Cisco had taken a different market – the business user – and used the Android platform to make a tablet-style computer that fits the market.

This has then allowed Cisco to develop a hardware product that can offer the necessary functionality by adding on microphones, video cameras, an interface to a speakerphone / handset dock amongst other things. They could easily take this unit further with concepts like the “next-generation home phone” or simply make a competing tablet MID based on Android under the Linksys consumer brand.

This can also lead to a Cius tablet having a longer service life beyond the business because of its ability to benefit from the Android Marketplace which could yield many consumer-focused applications like Android ports of applications like Skype or may iPhone apps.
