Abstract

An electronic apparatus with dual-sided touch device comprises a main body and a dual-sided touch device pivoted on the main body. The main body has a first case and a display panel disposed on one side surface of the first case. The dual-sided touch device has a second case and a dual-sided touch module disposed on the second case. In addition, the second case is pivoted on the first case. Also, the second case has two apertures in opposite directions. The second case can rotate relative to the first case and be against the first case to cover the display panel. Moreover, the dual-sided touch module has a light passable substrate and two light passable touch panels disposed on the two side surface of the substrate respectively. The two touch panels are exposed by the two apertures for sending a press signal and a track signal.

Claims

1. A dual-sided touch module, comprising:

a substrate made of a transparent material; and

two touch panels, wherein the two touch panels are light passable and disposed on two side surfaces of the substrate respectively for sending a press signal and a track signal by way of a touch.

2. The dual-sided touch module as claimed in claim 1, wherein each touch panel has two conductive layers parallel to the touch panel, the two conductive layers keep a distance with each other, and one of the conductive layers is connected with the substrate.

3. The dual-sided touch module as claimed in claim 2, wherein a plurality of spacers is disposed between the two conductive layers.

4. The dual-sided touch module as claimed in claim 2, wherein the two conductive layers are made of a light passable material.

5. The dual-sided touch module as claimed in claim 4, wherein the light passable material is Indium Tin Oxide (ITO).

6. The dual-sided touch module as claimed in claim 2, wherein each touch panel further include a protective layer attached on outer side surface of the touch panel.

7. An electronic apparatus with dual-sided touch device, comprising:

a main body having a first case and a display panel disposed on one side surface of the first case; and

a dual-sided touch device, comprising;

a second case pivoted on the first case, wherein the second case has two apertures in opposite directions, and the second case can be rotated relative to the first case and against the first case to cover the display panel; and

a dual-sided touch module disposed on the second case, wherein the dual-sided touch module has a light passable substrate and two light passable touch panels disposed on the two side surfaces of the substrate respectively, the two touch panels are exposed by the two apertures for sending a press signal and a track signal by way of a touch.

8. The electronic apparatus with dual-sided touch device as claimed in claim 7, wherein the main body further includes a control circuit and a sensor, the control circuit electrically connects with the two touch panels and the sensor, the sensor is used to send a trigger signal to the control circuit from the first case when the second case is against the first case, and then the control circuit turns off the touch panel toward the first case and turns on the other touch panel.

9. The electronic apparatus with dual-sided touch device as claimed in claim 7, further comprising a light conductive element attached to one of the two touch panels for dividing the touch panel into a plurality of different regions.

10. The electronic apparatus with dual-sided touch device as claimed in claim 8, further comprising a light source disposed on the second case for projecting light along outer side surface of the touch panel so as to let the light conductive element light-up after receiving the projecting light from the light source.

11. The electronic apparatus with dual-sided touch device as claimed in claim 7, further comprising a flexible thin film printed with a plurality of key patterns, wherein the flexible thin film can be retracted on the second case or pulled out on one of the two touch panels.
