The US Patent & Trademark Office recently published two patent applications from Samsung covering flexible displays and ebooks. Samsung's main patent filing generally relates to a flexible display device which is adapted to detect bending information, such as folding or bending of the flexible display device, and to output an image corrected on the basis of the bending information. Samsung's second patent filing generally relates to making page turning in future eBooks more realistic.
A New Samsung Flexible Display Patent Surfaces
In this first Samsung patent application that we're covering, we see one aspect of their progress in flexible display design. In patent FIG. 8 shown below we see a controller which will control an image displayed on the screen based on a value detected by the sensor part. That is, the controller receives bending information detected by the sensor part and performs a control to correct an image displayed on the screen depending on the position or bent angle of the bent location B or to output an image suitable for a UI or UX to the screen.
Samsung's patent FIG. 9 noted above illustrates how the flexible display device can be bent concavely or convexly. Additionally, when a location (noted as B in FIG 9) on the top of the touch screen part Is bent convexly or concavely, the controller 140 performs a control to zoom in or zoom out an image displayed on the touch screen part.
The Makeup of the Flexible Display
Samsung's patent FIG. 1 noted below illustrates the makeup of a flexible display device in accordance with the first embodiment of the present invention, and FIG. 2 illustrates the flexible display device of the first embodiment partially in cross-section. In both of these patent figures we see the multitouch screen on the top and the "bending detection part" # 100 at the bottom of display structure makeup.
According to Samsung, the touch screen is flexible so that it can be flexed, bent or rolled. The touch screen may output a screen desired by a user, or may serve as a User Interface (UI) to receive commands from the user.
The touch screen part employs a dual layer capacitive type construction including two Indium Tin Oxide (ITO) panels. However, this is merely an example, and any other construction may be employed if the construction is flexibly deformable and is capable of recognizing a screen touch when the user touches the screen to output an image. The touch screen of the dual layer capacitive construction including two ITO panels includes a top film 11, a first layer 12 and a second layer 13.
The top film 11 is flexible, and outputs images. As the top film is provided at the outermost area of the touch screen, it is desirable that the top film has such a high durability that the top film can protect the flexible display device from an external physical or mechanical impact.
The top film 10 may be preferably formed from PolyEthylene Terephthalate (PET), PolyCarbonate (PC), PolyMethylMethAcrylate (PMMA), PolyEthyleneNaphthalate (PEN), PolyEtherSulfone (PES), Cyclic Olefin Polymer (COP), glass or tempered glass. However, any other material may be also employed if it is highly flexible and durable when it is provided at the outermost area.
Samsung's patent was filed in the US in Q3 2012 under serial number 618086. The patent application was originally filed in Korea one year earlier.
A New Samsung eBook Patent Covering a Page Turning Effect
In a secondary patent filing, Samsung is trying to patent an ebook animation of a page turning with associated shadows. Androiders love to complain and rant about what they perceive to be Apple's frivolous patent filings. I say to them, take a long look in the Samsung mirror and say, what? Samsung is trying to patent the creation of a shadow for turning an eBook page? This is worthy of a patent?
Personally, I think the idea that Samsung is aiming to accomplish is just fine. Any time a company is pushing technology a little further I applaud them. But if this was Apple trying to patent this, Androiders would be having a field day on the net like mad zombies. But that's a topic for another day.
For Samsung's Patent FIG. 11b noted above, they state that "FIG. 11 illustrates a shadow effect of a page according to an embodiment of the present invention. A controller according to the present invention gives a shadow effect to a folded portion of a page."
Below in patent FIG. 8 we see an illustration of a procedure pertaining to modifying a page. A controller detects a touch position and a position variation, and modifies a page mesh to reflect it on a page based on the detected information. Thus, the page is modified in various ways according to a moving direction of the touch. Samsung's patent FIG. 3 noted below illustrates an example of a page mesh.
For more on this patent see patent application 20130104017 which describes this shadow effect along with their concept of making the turning of an ebook page more realistic.
