First, a method of detecting a user's grip using a user's touch on the touch screen will be described later with reference to FIG. A method of detecting the user grip using a separate sensor device will be described later with reference to FIGS. 7 and 8. FIG. A method of detecting a user grip using a physical button will be described later with reference to FIGS. 9 and 10. FIG. A method of detecting a user grip using an application program will be described later with reference to FIGS. 11 and 12. FIG.

The control unit 150 performs control for each configuration in the electronic device 100. [ Specifically, the control unit 150 can detect whether the electronic device 100 is mounted with the docking device. For example, when the docking apparatus 300 is electrically connected to the connection unit, the electronic apparatus 100 is provided with a connection unit capable of physically / electrically connecting to the docking apparatus 300, ) Is mounted on the docking device. The controller 150 may detect whether the docking apparatus is installed or not through the input of the adapter power when the adapter power is input through the docking apparatus 300. [

The controller 150 determines an operation mode depending on whether the docking device is mounted. The control unit 150 determines that the operation mode of the electronic device 100 is the desk mode and that the electronic device 100 is connected to the docking device 300 when the electronic device 100 is mounted on the docking device 300. [ The operation mode of the electronic device 100 can be determined to be the tablet mode.

The control unit 150 can determine the switching of the operation mode of the electronic device 100. [ Specifically, when the controller 150 senses the mounting of the docking device 300 in the tablet mode as described above, the controller 150 can determine to switch the operation mode of the electronic device 100 to the desk mode. On the contrary, when the controller 150 senses the detachment of the docking device 300 or receives the detach command from the user in the case of the desk mode, the controller 150 can determine the switching of the operation mode of the electronic device 100 to the tablet mode.

If the predetermined condition is satisfied, the control unit 150 may switch from the normal mode to the power saving mode. For example, there may be no command for a predetermined time. However, this is only an embodiment, and there are various cases of the mode change event.

If the predetermined condition is satisfied, the control unit 150 switches from the power saving mode to the normal mode. For example, when there is an operation of the physical button as described above, it is possible to switch from the power saving mode to the normal mode.

At this time, if the operation mode of the electronic device is the tablet mode, the control unit 150 can control the sensing unit 140 to detect the user's grip. If the user's grip is not detected, the control unit 150 may control the user interface unit 120 to display the first screen. The control unit 150 may control the user interface unit 120 to display a second screen having a non-screen area when a user's grip is detected. For example, if you change the resolution of 1920x1080 to 1680x1050 on a Windows system and specify the scaling item as the "center image" option, the screen size will not stretch to fit the screen.

If the user's touch on the non-screen area is detected while the user's grip is detected and the second screen having the non-screen area is displayed, the controller 150 displays the user's touch on the non- And the corresponding touch can be processed by a touch for malfunction. That is, the user touch command for the non-screen area can be handled as a non-control command.

As described above, when the grip of the user is detected, the electronic device 100 according to the present embodiment displays the non-screen area and does not use the user's touch on the non-screen area, Malfunctions can be prevented. In addition, since the malfunction of the user's grip can be eliminated, the bezel area can be minimized and the size of the smart device can be minimized or the screen area of the smart device of the same size can be maximized.

Fig. 3 is a view for explaining a grip shape of the user with respect to the electronic device.

Referring to FIG. 3, it can be seen that when the user grips the electronic device 100, it grips the bezel of the electronic device. In the illustrated example, the user's hand is shown as being connected only to the bezel area of the electronic device 100, but when the bezel of the electronic device is narrowly formed or when a large hand grasps the electronic device 100, A certain area of the user's hand may contact a certain area of the touch screen 200. [

Accordingly, in this embodiment, when a grip (specifically, grip on the touch screen area) of the user's electronic device is detected, a virtual panel area (or non-screen area) is displayed on the screen. This non-screen area will be described below with reference to Figs. 4 and 5. Fig. A method of detecting a user's grip will be described later with reference to FIGS. 6 to 12. FIG.

However, the display mode of the electronic device 100 is the vertical display mode, Or the lower side, the second screen may include a second screen area whose vertical length is narrower than the first screen size, and a non-screen area arranged above and below the second screen area. That is, a non-screen area can be created for an area where a user's grip on the touch screen may occur.

On the other hand, the size of the non-screen area can be set as a default in the manufacturer and can be changed by the setting of the user. For example, if the user has a larger hand than a normal person, the user can adjust the non-screen area to be wider than the non-screen area of the default size. If the user has a smaller hand than the general user, Area so that the user can adjust the size thereof to have a non-screen area smaller than the area.

Referring to FIG. 5, another example of a second screen displayed when a user's grip is detected is shown. Specifically, the second screen 200 'includes a second screen area 210' having a predetermined ratio smaller than the first screen size 200 and having a reduced width and height, and a non- The second screen area is configured to have the same ratio as the ratio of the existing first screen, and it is possible to reduce the user's sense of heterogeneity in screen switching .

In this embodiment, when the user's grip is detected, the size of the screen for displaying various information is reduced. However, such a representation may be described as a resolution change.

The control method as shown in Fig. 13 may be executed on an electronic device having the configuration of Fig. 2, or on an electronic device having other configurations.

Further, the control method as described above can be implemented as a program (or application) including an executable algorithm that can be executed in a computer, and the program is stored in a non-transitory computer readable medium Can be provided.

A non-transitory readable medium is a medium that stores data for a short period of time, such as a register, cache, memory, etc., but semi-permanently stores data and is readable by the apparatus. In particular, the various applications or programs described above may be stored on non-volatile readable media such as CD, DVD, hard disk, Blu-ray disk, USB, memory card, ROM,

14 is a diagram for specifically explaining a control method of the electronic device according to the present embodiment.

Referring to FIG. 14, a screen having a maximum screen (or a maximum resolution) (i.e., a first user interface window) is displayed (S1405).

When a touch on the touch screen is input, the input touch information is transmitted to the touch controller (S1410). The touch controller notifies the touch screen driver or the operating system driver of the input touch information (S1415), and the touch information is transmitted to the application (S1420).

If it is determined in step S11425 that the touch input based on the transmitted touch information is a touch by the user's grip on the electronic device (S11425), the resolution of the display is changed so that the screen has a non- (S1430).

If a touch for the non-screen area is input, the touch is set to be ignored (S1435).

If the grip state is not canceled (S1440-N), the current state is maintained (S1450). If the grip state is canceled (S1440-Y) The resolution of the display is changed so that a screen having no screen area is displayed (S1445)
