Abstract

A touch control device comprises: a button member receiving a touch input; a body member located below the button member; a signal deliverer arranged in the body member for having capacitance changed according to the touch input; a substrate having a receiver which is arranged on the substrate for receiving information about the capacitance from the signal deliverer; and a light emitting member for irradiating light onto the button member.

First claim

What is claimed is:

1. A touch control device comprising:
a button member receiving a touch input and having an opening;
a body member located below the button member;
a signal deliverer arranged in the body member for having a capacitance that changes when the touch input approaches or touches the button member;
a substrate having a receiver which is arranged on the substrate for receiving information about the capacitance from the signal deliverer;
a light emitting member for irradiating light onto the button member; and
a light transfer member passing through the body member and configured to guide light from the light emitting member to the opening,
wherein the signal deliverer is composed of a conductive material and includes:
a first signal deliverer disposed adjacent to the button member around the light transfer member; and
a second signal deliverer extending from the first signal deliverer to the receiver and delivering the information about the capacitance to the receiver,

wherein the first signal deliverer is arranged on a top face of the body member through which the light transfer member extends, and
the second signal deliverer has one end connected to the first signal deliverer and another end connected to the receiver.

2. The touch control device of claim 1 , wherein the body member has a side including a metal complex, in which an electrode groove is defined, and
wherein the signal deliverer having the conductive material is arranged in the electrode groove.

3. The touch control device of claim 2 , wherein the body member comprises a resin including one or more of polycarbonate (PC), polyamide (PA), or acrylonitrile-butadiene-styrene copolymer (ABS), and metal oxide including one or more of Mg, Cr, Cu, Ba, Fe, Ti, or Al.

4. The touch control device of claim 2 , wherein the body member includes a base, which has the metal complex, coated on one side of a basic member.

5. The touch control device of claim 1 , wherein the button member is composed of a metal.

6. The touch control device of claim 5 , further comprising a shielding member isolating the button member from the signal deliverer.

7. The touch control device of claim 1 , further comprising a controller for determining the information about the capacitance received from the receiver.

8. The touch control device of claim 7 , wherein the controller determines whether the touch input comes into contact with the button from the information about the capacitance between the signal deliverer and the receiver.

9. The touch control device of claim 8 , wherein the controller determines whether the touch input approaches the button within a predetermined range based on the information about the capacitance between the signal deliverer and the receiver.

10. The touch control device of claim 1 , wherein the body member is separated from the substrate,
wherein the touch control device further comprises an elastic member disposed between the body member and the substrate, and
wherein the button member and the body member are arranged to be movable in a vertical direction to press the elastic member.

11. The touch control device of claim 1 ,
wherein the light transfer member passes through the body member, and the body member has an inclined face around the light transfer member,
wherein the first signal deliverer is arranged on the inclined face, and
wherein the second signal deliverer has one end connected to the first signal deliverer and another end extending toward the receiver.

12. The touch control device of claim 11 , wherein some area of the first signal deliverer faces the opening of the button member.

13. The touch control device of claim 1 , wherein the light transfer member passes through the body member,
wherein the first signal deliverer is arranged on a face adjacent to the button member, and
the second signal deliverer extends around a through part of the body member, through which the light transfer member extends, toward the receiver.

14. A touch control device comprising:
a button member defining a touch area which is touchable, the button member composed of a metal and having an opening;
a substrate having a receiver arranged on the substrate for receiving a touch signal;
a body member disposed between the button member and the substrate;
a light emitting member for irradiating light;
a light transfer member passing through the body member and configured to guide light from the light emitting member to the opening; and
a signal deliverer comprising:
a first signal deliverer arranged in the body member to be adjacent to the button member around the light transfer member, the first signal deliverer having a capacitance that changes when a touch input approaches or touches the button member; and
a second signal deliverer extending from the first signal deliverer toward the receiver to deliver information about the capacitance of the first signal deliverer to the receiver,
wherein the first signal deliverer is arranged on a top face of the body member through which the light transfer member extends,
the second signal deliverer has one end connected to the first signal deliverer and another end extending toward the receiver, and
wherein the receiver receives the information about the capacitance of the first signal deliverer changed by the touch input.

15. The touch control device of claim 14 ,
wherein the first signal deliverer is arranged around a through part of the body member, through which the light transfer member extends.
