TOUCH SENSOR SYSTEM, AND ELECTRONIC DEVICE

摘要

A touch sensor system includes a driver which drives on the basis of code sequences which are orthogonal to one another and include +1 or−1 and each of which has a length N. A decoding section estimates on the basis of a first inner product operation of the outputs and the code sequences a first capacitance value and on the basis of a second inner product operation of the outputs and the code sequences a second capacitance value. A touch panel has a two-dimensional region including a hand placing region and a remainder region and processing sections.
