Abstract

An input device includes a touch pad may include a transmissive material, a touch detector disposed at a rear portion of the touch pad, a printed circuit board connected to the touch detector, and a plurality of light emitting devices mounted on the printed circuit board, wherein a plurality of input elements is provided on a back surface of the touch detector. Each input element has at least two symbols that are formed in overlap with each other and in mutually different colors.

Claims

1. An input apparatus comprising:

a touch pad including a transmissive material;

a touch detector disposed at a rear portion of the touch pad;

a printed circuit board connected to the touch detector;

a plurality of input elements disposed on a back surface of the touch detector, each input element having at least two symbols that are formed in overlap with each other and in mutually different colors; and

a plurality of light emitting devices respectively emitting light to the input elements.

2. The input apparatus of claim 1, wherein each light emitting device emits lights having at least two different colors corresponding to the mutually different colors of the symbols of each input element.

3. The input apparatus of claim 1, wherein the input elements are formed on a film, and

wherein the film is attached to a back surface of the touch pad.

4. The input apparatus of claim 1, wherein the input elements are printed on a back surface of the touch pad.

5. The input apparatus of claim 1, wherein the touch detector includes:

a capacitive detector having a plurality of electrodes.

6. The input apparatus of claim 5, wherein the electrodes include transparent materials.

7. The input apparatus of claim 1, wherein the touch detector is printed integrally with the input elements on a back surface of the touch pad.

8. The input apparatus of claim 1, wherein a support member is interposed between the touch detector and the printed circuit board, and

wherein the support member has a plurality of receiving openings in which the light emitting devices are received.

9. The input apparatus of claim 8, wherein the receiving openings are isolated from each other by a sealing wall.
