In the autumn we will meet with the fourth-generation Galaxy Note device and associate reported that Samsung filed a patent application for one of the future products : the company can use the pen that uses ultrasonic sensors to determine the coordinates of the contact with the screen. In this case, the additional layer sensitive display device is not required, it reduces its thickness, and lowers the cost.
Characteristically, this technology works with or without a pen . Qualcomm itself also demonstrated the technology in action on the example of a prototype tablet computer. It is not entirely clear how the Samsung patent will restrict the use of the ultrasonic method of entering information on the products of other Qualcomm partners .
