[Description on Figure 5-Transparent Touch]

FIG. 5 is a conceptual diagram illustrating a control method for a touch operation when a pair of display units 156 and 157 overlap.

The terminal disclosed in this drawing is a folder-type terminal in which a folder unit is foldable with respect to a main body. The first display unit 156 mounted on the folder unit may be a light transmissive type or a transparent type such as a TOLED, but the second display unit 157 mounted on the main body may have a form in which light does not penetrate like an LCD. The first and second display units 156 and 157 may be configured as touch screens capable of touch input, respectively.

For example, when a touch (contact touch or proximity touch) with respect to the first display unit or the TOLED 156 is detected, the controller 180 may determine the touch type and the touch time. At least one image of the list of images displayed in the TOLED 156 may be selected or run.

Hereinafter, touch, long touch, long touch & drag (drag) with respect to a method in which information displayed on another display unit or LCD 157 is controlled when a touch is applied to the TOLED 156 exposed to the outside in an overlapped form. The description is based on the input method separated by).

In the overlapped state (mobile terminal is closed), the TOLED 156 is disposed to overlap the lower side of the LCD 157. In this state, when a touch different from a touch for controlling the image displayed on the TOLED 156 is detected, for example, a long touch (for example, a touch lasting more than 2 seconds to 3 seconds), the controller 180 ) Causes at least one image of the image list displayed on the LCD 157 to be selected according to the sensed touch input. The result of the execution of the selected image is displayed in the TOLED 156.

The long touch can also be used to selectively move a desired one of the objects displayed on the LCD 157 (without its execution operation) to the TOLED 156. That is, the user may select one region of the TOLED 156 corresponding to a specific object of the LCD 157. In the long touch, the controller 180 moves the object to the TOLED 156 for display. The object displayed on the TOLED 156 may also be transferred to the LCD 157 and displayed according to a predetermined touch input, for example, flicking, swirling, or the like, on the TOLED 156. In this figure, the menu No. 2 displayed on the LCD 157 is moved to the TOLED 156 and displayed.

If another input, for example, a drag, is additionally detected along with the long touch, the controller 180 is a function related to the image selected by the long touch. Can be displayed on. In this figure, the case where the preview (male photograph) with respect to the 2nd menu (image file) is performed is illustrated.

When the preview screen is output and the drag is made to the TOLED 156 for another image while maintaining the long touch, the controller 180 controls the selection cursor (or selection bar) of the LCD 157. The selected cursor is displayed on the preview screen (woman photo). After that, when the touch (long touch and drag) is finished, the controller 180 displays the first image selected by the long touch.

The touch operation (long touch and drag) is performed when a slide (movement of the proximity touch corresponding to the drag) is detected along with the long proximity touch (the proximity touch lasting at least 2 seconds to 3 seconds) for the TOLED 156. The same applies to.

If a touch operation other than those mentioned above is detected, the controller 180 may operate in the same manner as a general touch control method.

The control method for the touch operation in the overlapped form may be applied to a terminal having a single display. In addition, the present invention can be applied to a terminal different from a folder type having a dual display.
