Abstract
Official abstract text for this publication.
A touch panel 10 , which has first and second metal resistive thin films (movable transparent electrode 12 and fixed transparent electrode 13 ) formed respectively on opposing surfaces of two layers of film or glass (movable glass 11 and fixed glass 14 ) disposed opposite each other at a predetermined space, is configured such that a predetermined radio frequency signal can be inputted/outputted to/from the movable transparent electrode 12 , and ground required for detecting an operation position in the touch panel 10 is connected via an inductive circuit of coils L 3 , L 4 and the like, thereby providing a configuration in which radio waves inputted/outputted to/from the movable transparent electrodes 12 are not grounded in terms of radio frequency.
First claim
Opening claim text (preview).
The invention claimed is: 1. A touch panel which comprises first and second electrodes formed respectively on opposing surfaces of film or glass disposed opposite each other at a predetermined space, and in which a voltage is alternately applied from a voltage applying source to one of the first and second electrodes and a position of touch operation is detected by a voltage of the other electrode generated in response to the touch operation, the touch panel comprising: a radio fr…
