FIG. 2 is a perspective view showing an appearance of an electronic device having a watch phone function according to an embodiment of the present invention. FIG. 3 is a perspective view of a display unit of an electronic device having a watch phone function according to an embodiment of the present invention, FIG.

2, the electronic device 100 includes an integrated small body of some or all of the components of FIG. 1, a band 200 connected to opposite ends of the small body, means 210 for clamping the band, For example, a buckle), or the like. On the front surface of the small body, a display screen of the display unit 151, a display screen, or a touch screen may be disposed on the display screen. Input means of the input unit (130 in FIG. 1), for example, a keypad, a touch pad, or other input means may be disposed on the side surface of the small body. In addition to the antenna for mobile communication, an antenna for receiving broadcast signals may be disposed on the side surface of the small body, and the antenna (s) may be installed to be able to be drawn out from the small body.

The band 200 and the buckle 210 serve to secure the small body of the electronic device 100 to the user's wrist, such as a wrist watch. The band 210 can be made of synthetic resin, metal, natural / artificial leather, high stretch material, or a combination thereof. In addition, the buckle 210 can be made of metal. Further, when the band 200 is made of a material having a high elasticity, the buckle 210 may be omitted.

However, the present invention is not limited thereto. For example, the electronic device 100 may be a conventional bar type, a slide type in which two or more bodies are movably coupled to each other, a folder type, Swing type, swivel type, and the like.

In the electronic device for guiding a watch phone function to which the present invention is applied, the band is not limited to the above-described buckle type band, a band composed of a material which is stretched or shrunk by a predetermined range due to elasticity, .

For example, the band of the electronic device according to the embodiment of the present invention may include a first band part integrally provided with the display part 151 of the electronic device and connected to one end of the display part 151, And a second band portion connected to and extending from the other end of the second band portion 151. Here, the first band portion and the second band portion may not be connected to each other. That is, as a result of the user wearing the electronic device on the wrist, a predetermined gap may be formed between the first band portion and the second band portion.

The display unit 151 may include a first display module 151a, a second display module 151b, and a touch pad (or a touch screen) The display unit 151 may have a structure in which the first display module 151a, the second display module 151b, and the touch pad (or the touch screen) 143 are stacked in this order or the second display module 151b, 1 display module 151a, and a touch pad (or touch screen) 143 in that order. 3 shows that the first display module 151a and the second display module 151b have the same size, but the second display module 151b is larger than the first display module 151a and the first display module 151a ). ≪ / RTI > The first display module 151a includes a low power liquid crystal display module such as a Passive Matrix Liquid Crystal Display (PMLCD) used as a display of an electronic clock and the second display module 151b includes a mobile phone, A high-definition liquid crystal display module such as an active matrix liquid crystal display (AMLCD) used in a TV, or a high-definition organic light emitting diode (OLED). In addition, a display module stacked on top of the first display module 151a and the second display module 151b may be formed of a transparent or semi-transparent display module.

As described above, it is needless to say that the form of the electronic apparatus to which the present invention is applied is not limited to the example shown in Fig.

3, the control unit 180 controls the first control module 180a to control the first display module 151a of the display unit 151 and the second control module 180b to control the display unit 151 And can separate functions to control the second display module 151b. Also, although not shown, a single controller 180 may control both the first display module 151a and the second display module 151b.

Specifically, when the operation mode of the watch phone performs an electronic clock function, which is a basic function, the control unit 180 transmits a control signal to the first control module 180a to convert the first display module 151a into an active state And controls the first display module 151a to display time information. In addition, when the operation mode of the watch phone performs the phone function, the controller 180 transmits a control signal to the second control module 180b to convert the second display module 151b into the active state, And display information related to the phone function through the display module 151b. When the control module controlling each operation mode is disconnected, the control module controlling the previous operation mode can transmit a control signal for converting the display module into the inactive state. For example, when the watch phone operates in the electronic clock operation mode, the first control module 180a displays time information through the first display module 151a, and when the watch phone is converted into the phone operation mode, The control module 180 controls the second display module 151b to display information related to the phone operation and the second control module 180b controls the first display module 151a as the first control module 180a It is possible to transmit a control signal for converting into the inactive state. That is, when the operation mode is changed, the display module which displays information related to the opposite operation mode is converted into the inactive state. Here, the inactive state may be one of an off state and a standby state.

Although the control unit 180 controls the first display module 151a and the second display module 151b in the following description, the same can be applied to the case where each control module controls each display module. The controller 180 or each of the control modules 180a and 180b may change the information displayed on the display module in the activated state according to the operation mode when the touch input is received through the touch pad 143. [ That is, the control unit 180 or the control modules 180a and 180b may process the touch input to the touch pad 143 as a touch input to the active display module.

4 is a flowchart of a method of controlling an electronic device having a watch phone function according to an embodiment of the present invention.

Referring to FIG. 4, the control unit 180 of FIG. 1 determines the operation mode of the electronic device having the watch phone function (S110) and selectively sets (or changes the display module corresponding to the current operation mode) (S120).

Specifically, the control unit (180 in FIG. 1) can determine the operation mode of the electronic device as one of a first operation mode for operating as an electronic clock or a second operation mode for operating as a mobile phone.

When the operation mode of the electronic device is determined to be the first operation mode, the control unit (180 of FIG. 1) may set or change the first display module to the active state and set or change the second display module to the inactive state. On the other hand, when the control unit (180 in FIG. 1) determines that the operation mode of the electronic device is the second operation mode, it can set or change the second display module to the active state and set or change the first display module to the inactive state . The controller (180 of FIG. 1) may set the display module to the active state or the inactive state when all of the states of the first and second display modules are not determined, and may otherwise change the state.

The electronic device 100 having a watch phone function can not determine the operation mode when the power is turned off, so that both the first display module and the second display module are off (disabled), and when the power is turned on The operating mode and the selectively activated display module are determined.

The first display module is set to the active state when the electronic device is powered on and the initial operation mode is set to the first operation mode and then the first display module or the second display module is turned on until the power of the electronic device is turned off, Can be maintained in the activated state.
