Detecting sensor, indicator position detecting device, and method for manufacturing detecting sensor

Abstract

A detecting sensor, an indicator position detecting device, and a method for manufacturing the detecting sensor can prevent error detection when fingers and other indication body touch a routing area around. The detecting sensor is on a first glass substrate (15), including: on a first direction, a plurality of transmiting conductors (11); on a second direction crossed with the first direction, a plurality of receiving conductors (13); a plurality of metal routing conductors (19A) connected with transmiting conductors (11); and a plurality of metal routing conductors (19B) connected with receiving conductors (13). Ground plane is configured between the metal routing conductors (19A) and the first glass substrate (15). The ground plane and the mtal routing conductors are electrical isolation. The ground plane given preconcerted electrical potential comprises the same materials with the transmiting conductors (11) or receiving conductors (13).

Description

technical field [0001] The present invention relates to a detection sensor, a pointer position detection device and a method of manufacturing the detection sensor. The detection sensor is arranged on the surface of a display screen to detect the position of a pointer. Background technique [0002] Conventionally, there is known a capacitive input device which is arranged on the surface of a display screen of a liquid crystal display device, detects its position when touched by a user's finger, etc., and inputs information corresponding to a displayed instruction image (for example, refer to Patent Document 1). In this capacitive input device, translucent electrode patterns intersecting each other are formed on the surface of a translucent substrate, and the position of the user's finger is detected based on a change in capacitance generated when the user's finger comes into contact with the surface.

AI Technical Summary

Problems solved by technology

On the translucent substrate 15, the range other than the metal wiring 9a is set as the input area 10a. In the wiring area arranged adjacently, similar to the case where the user's finger touches the input area 10a, the capacitance between the two light-transmitting electrode patterns 11 and 12 changes, so there is a problem that erroneous detection of the input position occurs.
