Method for displaying speed dial information and device using the method

1. A method for displaying speed dial information, comprising: defining and storing a dialing signal in a memory of a mobile communication device;

when the mobile communication device receives an operation representing a surface of a physical button is touched, generating a trigger signal and displaying contact information corresponding to the physical button on a screen of the mobile communication device in response to the trigger signal;

when the mobile communication device further receives an operation representing the physical button is pressed, generating a dialing signal; defining a first time threshold value; and dialing a phone number assigned to the pressed physical button by the mobile communication device if a time for receiving the dialing signal reaches the first time threshold value;

wherein the physical button is a number button, and if the time for receiving the dialing signal does not reach the first time threshold value, a number on the pressed number button is inputted by the mobile communication device,

wherein the physical button is a screen button comprising a touch screen and a metal dome under the touch panel, and the method further comprising:

generating the trigger signal when the touch screen is touched; and

generating the dialing signal when the metal dome is pressed.

2. The method for displaying speed dial information as claimed in claim 1 , further comprising: defining a force threshold value; and generating the dialing signal if a force value for pressing the pressed physical button reaches the force threshold value.

3. The method for displaying speed dial information as claimed in claim 1 , wherein the physical button comprises a touch panel thereon, and the method further comprising: generating the trigger signal when the touch panel is touched.

4. A mobile communication device, comprising: a screen; a dialing module, comprising a physical keypad providing a plurality of physical buttons; a memory, storing a dialing signal defined for the dialing module;

a signal receiving module, receiving a trigger signal and a pressed signal generated by touching and pressing one of the physical buttons of the physical keypad, respectively; and

a microcontroller, receiving the trigger signal and the pressed signal via the signal receiving module

wherein the microcontroller displays contact information corresponding to the physical button on the screen when the trigger signal is received, and the microcontroller performs the dialing signal when the pressed signal is received,

wherein the memory stores a first time threshold value, and a contact phone number assigned to the pressed physical button is dialed by the dialing module if a time for receiving the dialing signal reaches the first time threshold value,

wherein the physical button is a number button, and a number on the pressed number button is inputted by the dialing module if the time for receiving the dialing signal does not reach the first time threshold value,

wherein the physical button is a screen button, comprising a touch screen and a metal dome under the touch panel, the trigger signal generated when the touch screen is touched, and the dialing signal generated when the metal dome is pressed.

5. The mobile communication device as claimed in claim 4 , wherein the memory stores a force threshold value and the dialing signal is generated if a force value from pressing the pressed physical button reaches the force threshold value.

6. The mobile communication device as claimed in claim 4 , wherein the physical button comprises a touch panel thereon, the trigger signal generated when the touch panel is touched.

7. A non-transitory computer readable medium containing instructions for performing the method of claim 1 .

8. The method for displaying speed dial information as claimed in claim 1 , further comprising: defining a second time threshold value; and generating the trigger signal if a time for continuously touching the physical button received by the mobile communication device reaches the second time threshold value.

9. The mobile communication device as claimed in claim 4 , wherein the memory stores a second time threshold value, and the trigger signal is generated if a time for continuously pressing the physical button received by the signal receiving module reaches the second time threshold value.
