摘要： A touch panel system includes an electrostatic capacitance type touch panel including a drive electrode, a position detection electrode, and a pressing force detection electrode; and a controller configured to provide a drive signal to the drive electrode and acquire a position signal value from the position detection electrode and a pressing force signal value from the pressing force detection electrode. The controller detects a position of a pointer based on the position signal value, and acquires a pressing force generated by the pointer based on a rate of change of a smoothed value of the pressing force value based on the pressing force signal value.

摘要： There are provided an antenna device with improved antenna performance while suppressing a decrease in yield and a decrease in viewability, and a display device including the same. The antenna device includes an antenna substrate, a first antenna pattern formed on a first main surface of the antenna substrate, and a second antenna pattern formed on a second main surface opposite to the first main surface of the antenna substrate. The first antenna pattern and the second antenna pattern are formed such that positions on the front and back of the antenna substrate coincide with each other, and at least a part of the antenna substrate is transparent to transmit an image.
