Abstract
The present invention relates to a touch sensor and a fabrication method thereof in which sensor electrodes in the active area is connected to the trace via a bridge electrode.
Claims12
A touch sensor comprising:
- a substrate;
- an active area in which sensor electrodes are arranged on the substrate;
- a trace located on a boundary of the active area on the substrate to connect the sensor electrodes to a touch sensor wiring;
- and
- at least one trace bridge electrode electrically connecting the sensor electrodes to the trace.

A method for preparing a touch sensor comprising the steps of:
- forming a first conductive pattern including a sensor electrode pattern and a first trace pattern on a substrate;
- forming a second trace pattern on at least a part of the first trace pattern;
- applying and patterning an insulation layer for covering at least one of the first conductive pattern and the second trace pattern;
- and
- forming a trace bridge electrode electrically connecting at least a part of the sensor electrode pattern to the first or the second trace pattern on the insulation layer.
