Touch sensitive module with integrated sensor and artwork
First Claim
1. A touch sensor panel comprising:
- a plurality of first lines of a first conductive material located on a first substrate in a visible area and a border area of the touch sensor panel;
a second conductive material electrically connected to the plurality of first lines to create one or more traces for off-panel connections and disposed directly on the plurality of first lines in the border area; and
an opaque layer located at least partially in the border area and directly contacting the first substrate on a first side of the opaque layer and an adhesive on a second side of the opaque layer, opposite the first side; and
a passivation layer located on the first substrate in the border area and the visible area, the passivation layer being separate and distinct from the opaque layer,wherein the opaque layer is a conductive ink.

Abstract
A touch sensor panel including artwork formed on the touch sensor panel is disclosed. The touch sensor panel stackup can include a substrate, one or more underlying layers, one or more patterned transparent conductive layers, a passivation layer, artwork, and an adhesive layer. The artwork on the touch sensor panel can be formed by aligning to the touch sensor pattern or alignment marks. In some examples, the artwork can be formed on a discrete touch sensor panel, and the discrete touch sensor panel can be bonded to a cover glass or cover material. In some examples, the touch sensor panel can be a Dual-sided Indium Tin Oxide (DITO) stackup. In some examples, the drive lines and the sense lines of the touch sensor panel can be formed on separate substrates, and the substrates can be bonded together using an adhesive.
