Abstract
A touch sensing module includes a substrate, sensing electrodes, and a covering layer. The sensing electrodes are disposed on a surface of the substrate. Each of the sensing electrodes has a first end and a second end opposite to the first end. The second end is adopted to be electrically connected with an external circuit. The covering layer is disposed on a side of the sensing electrodes distal from the substrate, and covers the sensing electrodes. The covering layer has openings. The first ends of the sensing electrodes are exposed within the openings respectively.
Claims7
A touch sensing module, comprising:
- a substrate having a first surface;
- a plurality of first sensing electrodes disposed on the first surface, wherein each of the first sensing electrodes has a first end and a second end opposite to the first end, the second end is configured to be electrically connected with an external circuit;
- a first covering layer covering the first sensing electrodes and having a plurality of first openings, wherein the first covering layer and the substrate are positioned on two opposite sides of the first sensing electrodes, and the first ends are exposed within the first openings respectively;
- a plurality of test pads disposed directly on the first ends of the first sensing electrodes respectively, wherein at least a part of the test pads are exposed directly to open air within the first openings respectively;
- a plurality of first external-connecting electrodes disposed directly on the first surface, wherein the first external-connecting electrodes are connected with the second ends of the first sensing electrodes respectively, the first covering layer further has at least one second opening, exposed the first external-connecting electrodes;
- and
- a plurality of connecting routes disposed on the first surface directly connecting the second ends of the first sensing electrodes to the first external-connecting electrodes respectively, wherein vertical projection of at least one of the first ends projected on the first surface is located between the connecting routes and the first sensing electrodes and is located in a peripheral region.
