Abstract

The invention provides a touch panel including: two resistive layers; a plurality of spacer dots disposed between the two resistive layers, the spacer dots spacing the two resistive layers apart from each other, the two resistive layers facing each other; and a glass panel bonded to an underside of one of the resistive layers to provide support, the one of the resistive layers positioned opposite from a touch surface, wherein one side of the glass panel has at least one region including a material having a modulus of elasticity different from a modulus of elasticity of the glass panel, the one side of the glass panel being adjacent to the one of the resistive layers. With this configuration, the touch sensitivity in the at least one region is differentiated from that of the remaining regions.

Claims

1. A resistive touch panel, comprising:

two resistive layers;

a plurality of spacer dots disposed between the two resistive layers, the spacer dots spacing the two resistive layers apart from each other, the two resistive layers facing each other; and

a glass panel bonded to an underside of one of the resistive layers to provide support, the one of the resistive layers positioned opposite from a touch surface,

wherein one side of the glass panel has at least one region including a material having a modulus of elasticity different from a modulus of elasticity of the glass panel, the one side of the glass panel being adjacent to the one of the resistive layers.

2. The resistive touch panel according to claim 1,

wherein the one side of the glass panel has a plurality of regions including the material having the modulus of elasticity different from the modulus of elasticity of the glass panel.

3. The resistive touch panel according to claim 1,

wherein the at least one region at the one side of the glass panel has a recessed portion and the material having the modulus of elasticity different from the modulus of elasticity of the glass panel is disposed in the recessed portion.

4. The resistive touch panel according to claim 1,

wherein the at least one region at the one side of the glass panel has a through hole and a member closing a bottom of the through hole, and the material having the modulus of elasticity different from the modulus of elasticity of the glass panel is disposed in a region formed by the through hole and the member closing the bottom.
