Abstract
A touch panel, a fabricating method, a repair method, and a touch device are provided. The touch panel includes a substrate, and a touch electrode layer, the repair lines, and repair conductive portions, on the substrate. The touch electrode layer includes a touch electrode array. The repair lines are outside the touch electrode array. In a direction perpendicular to the touch panel, at least part of touch electrodes at edges of the touch electrode array overlaps the repair conductive portions, and/or the repair conductive portions overlap at least part of repair lines.
Claims18
A touch panel, comprising:
- a substrate;
- and
- a touch electrode layer, the repair lines, and repair conductive portions, on the substrate, wherein:

- and
- in a direction perpendicular to the touch panel, at least part of touch electrodes at edges of the touch electrode array overlaps the repair conductive portions, and/or the repair conductive portions overlap at least part of repair lines.
A touch device comprises:
- a touch panel, comprising:
- a substrate;
- and
- a touch electrode layer, the repair lines, and repair conductive portions, on the substrate, wherein:
- the touch electrode layer comprises a touch electrode array, and the repair lines are outside the touch electrode array;
- and
- in a direction perpendicular to the touch panel, at least part of touch electrodes at edges of the touch electrode array overlaps the repair conductive portions, and/or the repair conductive portions overlap at least part of repair lines.
A fabricating method of a touch panel, comprising:

- forming a touch electrode film layer on the substrate;
- coating a photoresist over the touch electrode film layer and curing the coated photoresist;
- exposing the cured photoresist, and removing a portion of the photoresist to expose the touch electrode film layer;
- and
- etching the touch electrode film layer to form the touch electrode array.
A repair method of a touch panel, comprising:
- providing a touch panel including:
- a substrate;
- and a touch electrode layer, repair lines, and repair conductive portions, on the substrate, wherein the touch electrode layer comprises a touch electrode array, and the repair lines are outside the touch electrode array;
- in a direction perpendicular to the touch panel, at least part of touch electrodes at edges of the touch electrode array overlap the repair conductive portions, and/or the repair conductive portions overlap at least part of repair lines;
- and
- when a portion of the touch panel is detected to be repaired, electrically connecting the repair conductive portions with an overlapped portion between the repair conductive portions and the at least part of repair lines.
