S Pen, an integral part of phablets from the Samsung range Galaxy Note, it will most likely get some sort of upgrade. Samsung has patented an innovation in the form of the S Pen with ultrasound technology in South Korea. Specifically, this S Pen is supposed to work on the basis of ultrasonic waves, which will be captured by four sensors located on the sides of the device.
By using ultrasound technology, there will no longer be a need for a digitizer on the screen Galaxy Note, which can result in a lower price of the phablet itself and, of course, a thinner display. However, a stylus pen based on ultrasound is not a groundbreaking innovation, as Qualcomm already introduced a tablet with similar technology this year. And if earlier speculations come true, according to which there will be one of two versions Galaxy The Note 4 has a Snapdragon 805 processor, just like the mentioned tablet, we may see an ultrasonic S Pen already this September/this September. Or not and Samsung will keep this technology on one of the other lines of this device, it is only up to the South Korean company how to deal with this patent.
