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.
Claims14
A sensor for detecting a pen signal transmitted from a pen, comprising:
- a touch sensor having first electrodes extending in a first direction and second electrodes extending in a second direction perpendicular to the first direction, which form a rectangular-shape position detection area and are configured to respectively receive the pen signal;
- first flexible printed circuit (FPC) connector terminals that are arranged in a first region outside an edge of the position detection area, the edge extending in the second direction, and that are connected to the first electrodes, respectively;
- and
- second flexible printed circuit (FPC) connector terminals that are arranged in a second region outside said edge of the position detection area and that are connected to at least some of the second electrodes, respectively
- wherein,
- the first region and the second region are outside the same edge extending in the second direction, and the first FPC connector terminals and the second FPC connector terminals extend in the first direction, and
- the first region and the second region are separated from each other by a distance in the second direction, the distance being greater than a width R which is a spanning distance across a reachable range of the pen signal on the touch sensor, wherein the reachable range of the pen signal is an area on the touch sensor capable of receiving the pen signal at a given time.
