## Abstract

A touch panel has a substrate, a touching layer, an interval frame and a moisture resisting assembly. First and second electric conductive layers are formed respectively on opposite surfaces of the substrate and the touching layer. The interval frame is formed between the substrate and the touching layer to form a space and has an air hole. The moisture resisting assembly is mounted in the air hole to allow air entering the space and prevent moisture entering the space.

## Claims

### Claim 1

A touch panel comprising
a substrate having a top surface;
a touching layer having a bottom surface facing to the top surface of the substrate;
a first and second electric conductive layers formed respectively on the top surface of the substrate and the bottom surface of the touching layer;
an interval frame mounted annularly between the substrate and the touching layer to form a space between the substrate and the touching layer and having
four edges; and
at least one air hole, each one of the at least one air hole formed through one of the four edges of the interval frame; and
at least one moisture resisting assembly, each one of the at least one moisture resisting assembly mounted in a corresponding air hole of the interval frame to allow air entering the space and prevent moisture entering the space.

### Claim 2 (depends on 1)

The touch panel as claimed in claim 1, wherein each one of the at least one moisture resisting assembly comprises multiple moisture resisting sheets mounted crisscross in the corresponding air hole of the interval frame.

### Claim 3 (depends on 2)

The touch panel as claimed in claim 2, wherein the moisture resisting sheets extend into the corresponding air hole of the interval frame.

### Claim 4 (depends on 2)

The touch panel as claimed in claim 2, wherein the moisture resisting sheets are insulating.

### Claim 5 (depends on 1)

The touch panel as claimed in claim 1, wherein each one of the at least one moisture resisting assembly comprises multiple moisture filtering members.

### Claim 6 (depends on 1)

The touch panel as claimed in claim 1, wherein each one of the at least one moisture resisting assembly comprises multiple moisture resisting sheets and multiple moisture filtering members mounted alternatively in the corresponding air hole of the interval frame.

### Claim 7 (depends on 1)

The touching control panel claimed in claim 1, wherein each one of the at least one air hole of the interval frame is a cutout.

### Claim 8 (depends on 1)

The touching control panel claimed in claim 1, wherein each one of the at least one air hole of the interval frame is a through hole.

### Claim 9 (depends on 1)

The touch panel claimed in claim 1, wherein the substrate and the touching layer are rectangular and are similar to each other.

### Claim 10 (depends on 9)

The touch panel claimed in claim 9, wherein the interval frame is a rectangular frame.
