Abstract
A sensor is provided for detecting a pen signal transmitted from a pen. The sensor includes a touch sensor, flexible printed circuit (FPC) connector terminals, and a detection pattern. The touch sensor has linear electrodes, which form a position detection area and are configured to respectively detect the pen signal. The FPC connector terminals are connected to the linear electrodes, respectively, via routing traces arranged outside the position detection area. The detection pattern is arranged in a region outside the position detection area, near the FPC connector terminals, and is configured to detect the pen signal.
Claims18
A sensor for detecting a pen signal transmitted from a pen, comprising:
- a touch sensor having first electrodes, which form a position detection area and are configured to respectively detect the pen signal;
- flexible printed circuit connector terminals including first flexible printed circuit connector terminals, which are connected to the respective first electrodes via first routing traces arranged in a region outside the position detection area;
- and
- a detection pattern, which is arranged in the region outside the position detection area and adjacent to the flexible printed circuit connector terminals, and which is configured to detect the pen signal.
A sensor for detecting a pen signal transmitted from a pen, comprising:
- a touch sensor having first electrodes and second electrodes, which form a position detection area and are configured to respectively receive the pen signal;
- first flexible printed circuit connector terminals arranged in a first region outside the position detection area, and connected to the first electrodes, respectively;
- and
- second flexible printed circuit connector terminals arranged in a second region outside the position detection area, and connected to at least some of the second electrodes, wherein
- the first region and the second region are separated from each other by a distance greater than a width of a reachable range of the pen signal on the touch sensor.
A sensor for detecting a pen signal transmitted from a pen, comprising:
- a touch sensor having first electrodes, which form a position detection area and are configured to respectively receive the pen signal;
- first flexible printed circuit connector terminals arranged at equal intervals outside the position detection area, and connected to the first electrodes, respectively;
- and
- first routing traces, which are arranged at equal intervals outside the position detection area, and which connect the first electrodes to the first flexible printed circuit connector terminals, respectively, wherein
- the first routing traces have portions arrayed across a collective width that is smaller than a collective width of the first flexible printed circuit connector terminals in an array direction.
