Touch screen display device and application thereof

1. A touch screen display device comprising:

a touch screen;

a sensor for detecting if the touch screen display device is being inserted in a connection chamber;

a control element electrically connected to the sensor and configured to generate a control signal according to an insertion status of the touch screen display device; and

a sensitivity-setting element configured to set the touch screen to a first sensitivity or a second sensitivity according to the control signal, wherein the touch screen with the second sensitivity is less sensitive than with the first sensitivity.

2. The touch screen display device of claim 1 , wherein the control element comprises:

an insertion signal generator for generating an insertion signal upon detection that the touch screen display device is being inserted in the connection chamber; and

a separation signal generator for generating a separation signal upon detection that the touch screen display device is not being inserted in the connection chamber.

3. The touch screen display device of claim 2 , wherein the sensitivity-setting element comprises:

an insertion-setting element for setting the touch screen to the first sensitivity upon receipt of the insertion signal; and

a separation-setting element for setting the touch screen to the second sensitivity upon receipt of the separation signal.

4. The touch screen display device of claim 1 , further comprising:

a secondary battery for supplying the touch screen display device with power as needed; and

a charging module for charging the secondary battery when the touch screen display device is being inserted in the connection chamber.

5. The touch screen display device of claim 1 , wherein the sensor is a tact switch.

6. The touch screen display device of claim 1 , wherein the sensor is a magnet sensor.

7. The touch screen display device of claim 1 , wherein the sensor is a photointerrupter.

8. A method for setting sensitivity of a touch screen of a touch screen display device, wherein the touch screen display device comprises the touch screen and a sensor, and the method comprises the steps of:

detecting if the touch screen display device is being inserted in a connection chamber of an electronic device utilizing the sensor of the touch screen display device;

setting the touch screen of the touch screen display device to a first sensitivity upon detection that the touch screen display device is not being inserted in the connection chamber; and

setting the touch screen of the touch screen display device to a second sensitivity upon detection that the touch screen display device is being inserted in the connection chamber, wherein the touch screen with the second sensitivity is more sensitive than with the first sensitivity.

9. An electronic device comprising:

a body;

a connection chamber provided in the body; and

a touch screen display device comprising:

a touch screen;

a sensor for detecting if the touch screen display device is being inserted in the connection chamber;

a control element electrically connected to the sensor and configured to generate an insertion signal upon detection that the touch screen display device is being inserted in the connection chamber; and

a sensitivity-setting element for enhancing sensitivity of the touch screen upon receipt of the insertion signal.

10. The electronic device of claim 9 , further comprising:

a transparent side provided on the body and configured to expose the touch screen when the touch screen display device is being inserted in the connection chamber.

11. The electronic device of claim 9 , wherein the touch screen display device further comprises:

a secondary battery for supply the touch screen display device with power as needed; and

a charging module configured to be electrically connected with the body and the secondary battery so as to charge the secondary battery when the touch screen display device is being inserted in the connection chamber.

12. The electronic device of claim 9 , wherein the sensor comprises a tact switch provided on the touch screen display device.

13. The electronic device of claim 12 , wherein the sensor further comprises:

a bolt provided in the connection chamber and configured to press the tact switch when the touch screen display device is being inserted in the connection chamber so as for the sensor to determine that the touch screen display device is being inserted in the connection chamber.

14. The electronic device of claim 9 , wherein the sensor comprises a magnet sensor provided on the touch screen display device.

15. The electronic device of claim 14 , wherein the sensor further comprises:

a magnet provided in the connection chamber and configured to change a magnetic detection status of the magnet sensor when the touch screen display device is being inserted in the connection chamber so as for the sensor to determine that the touch screen display device is being inserted in the connection chamber.

16. The electronic device of claim 9 , wherein the sensor comprises a photointerrupter provided on the touch screen display device.

17. The electronic device of claim 16 , wherein the sensor further comprises a light-shielding wall provided in the connection chamber and configured to interrupt a light ray falling on the photointerrupter when the touch screen display device is being inserted in the connection chamber so as for the sensor to determine that the touch screen display device is being inserted in the connection chamber.
