This week the US Patent & Trademark Office published a patent application from Samsung revealing an advanced hybrid touchscreen. The new design will allow a user to work in regular touch mode or via a new "Touch Pen" mode that will turn off the regular touch display so that the display is always in one mode or the other and not in both at any given time. This is designed to provide users with greater handwriting accuracy when you using a "Touch Pen," which a vastly different from the old stylus of yesteryear. Samsung notes that there are two likely ways that users will have to activate the new Touch Pen mode of the hybrid display and our report points them out for you.
Samsung Invents a New Hybrid Touchscreen that Works with a Touch Pen
There are many kinds of touch displays on the market today including resistive, capacitive, ultrasonic, optical and electromagnetic touch panels. In general, a touchscreen devices inputs accepts data input by using a user's finger of a stylus.
Recently a new kind of display has been developed that's better known as a hybrid touchscreen that works with a "Touch Pen," which differs greatly from the stylus of yesteryear.
A hybrid touchscreen device generally uses a capacitive touch panel to detect a user's finger, and generally uses an electromagnetic induction pen touch panel to detect an input of a touch pen. The device in affect uses two recognition systems for the hybrid touchscreen device to be operable. Such systems can lead to errors if a touch pen and user's palm rests on the display while writing.
Samsung's latest invention in this field advantageously solves at least some of problems and/or disadvantages associated with first generation hybrid displays. Samsung's next generation hybrid touch displays will achieve superior input reliability, and a method for operating the same.
In Samsung's patent FIG. 1 noted below we see a perspective view illustrating an example of operation of a hybrid touchscreen device of a portable terminal by a touch pen according to an exemplary embodiment of the present invention.
More preferably, the pen touch panel comprises an electromagnetic induction touch panel that detects the approach of a touch pen when the touch pen approaches within a predetermined distance before being touched to a touch screen device. Preferably, the predetermined distance may be about 2 cm.
The pen touch panel may also be a spatial touch panel such as an infrared touch panel or a sonic touch panel, which would detect the presence of a pen according to their respective technology.
In Samsung's patent FIG. 2 noted above we see is a cross-sectional view illustrating a configuration of the touch pen of FIG. 1. Samsung notes that the internal body of the pen (#20) could be made from a magnetic material body such as a ferrite chip.
As shown in Samsung's patent FIG. 3 below, when the touch pen approaches within a predetermined distance, e.g. 2 cm from the top device window, the "Pen Touch" panel #183 detects the approach of the touch pen.
In this case, the portable terminal detects the use of the pen touch panel and deactivates a user finger detection function of the touch panel #182. In this way, even when the touch pen approaches within a detection distance of the portable terminal, a user's palm imprint on the display will not affect the output in any way.
In another method, Samsung may provide the user with a simple interface setting to activate or deactivate the "Touch Pen" hybrid display as noted below in patent figure 9.
Samsung filed their patent application under serial number 7288337 back in Q4 2012 in the US and in Q1 in Korea under application number 10-2012-0019316. Samsung's last ePen patent was published in June 2012. Considering that this is a patent application, the timing of such a product to market is unknown at this time.
For the Record: At the moment, Apple is the most aggressive tech company filing patents for a future iPen – even though the company has consistently downplayed such a tool since the debut of the iPhone. You could review their iPen related patent filings here. Microsoft is another aggressive top tier technology company pushing new ePen patents through the system. You could find a number of their patents listed here. Although there's a large body of patents on the subject, these magical new smart pens have yet to make it to market. Here's to hoping that someone will crack the current problems with digital pens and deliver a winner. May the best team win.
