Apple Granted Two Original 2007 Multi-Touch Display Patents

1 Apple Granted Two Original 2007 Multi-Touch Display Patents
The US Patent and Trademark Office officially published a series of twenty-nine newly granted patents for Apple Inc. today. In our fourth granted patent report of the day we focus on two patents relating to Apple's original 2007 multi-touch technology. The patents go into great detail about display technology that even includes In-Plane Switching that is used in Apple's current iMac. Just last week Apple gained another granted patent related to multi-touch technology – and so it's beginning to appear that the hard work that Apple's engineers put into the revolutionary iPhone and iDevice revolution in general are beginning to pay off.  And finally, our report closes out with a listing of seventeen utility patents covering such things as the face recognition feature found on iDevice cameras, the button assembly for the iPhone as well as the electronic sighting compass for iDevices and much more. All in all, today has been a granted patent bonanza for Apple. 


Apple Granted Two Original 2007 Multi-Touch Patents


Apple has been granted two original 2007 multi-touch patents. The first is titled "Touch screen liquid crystal display" and lists a whopping 85 patent claims.


The first granted patent's abstract reads as follows:


Apple's invention relates to "liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.


Apple's patent FIG. 102 shown below illustrates an application of a multi-touch screen LCD; FIG. 94 illustrates a touch screen LCD device assembly; FIG. 50 illustrates further aspects of touch screen integration for the embodiment of FIG. 47.





Apple's second granted patent titled "Multi-touch input discrimination." Apple's patent abstract reads as follows:


"Techniques for identifying and discriminating between different types of contacts to a multi-touch touch-screen device are described. Illustrative contact types include fingertips, thumbs, palms and cheeks. By way of example, thumb contacts may be distinguished from fingertip contacts using a patch eccentricity parameter. In addition, by non-linearly deemphasizing pixels in a touch-surface image, a reliable means of distinguishing between large objects (e.g., palms) from smaller objects (e.g., fingertips, thumbs and a stylus) is described."


Another site is claiming that Apple's original 2007 patents relate to In-Cell technology. We disagree. The complexity of Apple's LCD technology which is shown below in patent FIG. 6 juxtaposed with a graphic of a simpler next generation process involving In-Cell technology just don't mesh at all. One of the technologies that Apple's patent in fact touches on is that of in-plane-switching (IPS), which is used in Apple's current iMac.
