As shown in FIG. 4, when a messenger login menu is selected to access a messenger server for transmitting an instant message, the controller 180 displays a window in which an ID and password for messenger login are input (S400). When the user is authenticated by the input ID and password, the controller 180 displays a list window including the contact list on the display unit 151 (S405). Here, the list included in the list window may be a list that displays all the people registered in the user's messenger on the conversation, or may be a list that displays the person who is connected to the messenger server among the people registered in the conversation. It may also be a list displaying only the chat partner of the running chat window. The list displayed on the list window may be changed according to a user's selection. Meanwhile, the list window may include a menu for logout, file transfer, etc., as well as the contact list.

Next, when one person is selected from the contact list displayed in the list window (S410), the controller 180 executes a chat window for transmitting a message with the selected chat partner and is transparent to the display unit 151 so as to overlap the list window. To display (S415). Here, one person is not necessarily selected from the conversation partner list, and the present invention includes a case for transmitting and receiving a multi-party message that generates one conversation window. In S410, a plurality of people running one or one chat window may be selected by a touch input input through the list window displayed on the display unit 151.

Next, the controller 180 determines whether a message is transmitted and received to the selected chat partner, that is, the chat partner of the displayed chat window (S420). As a result of the determination in S420, when the message is transmitted and received, the controller 180 displays the transmitted and received message on the chat window displayed on the display unit 151 (S425). If all of the transmitted and received messages are difficult to be displayed on the display unit 151, a scroll bar may be displayed on the chat window, and the message displayed on the chat window may be confirmed through the scroll bar.

When the message is transmitted and received in S425 and displayed in the chat window, or when the message is not transmitted or received in S420, the controller 180 determines whether an end input for terminating the chat window displayed on the display unit 151 is selected (S430). The end input of the chat window may be selected through a touch input through a specific portion of the chat window displayed on the display unit 151.

As a result of determination in S430, when an end input for the displayed chat window is selected, the controller 180 ends the display of the chat window displayed on the display unit 151 (S435). Next, the controller 108 determines whether there is a chat window that is not terminated (S440). As a result of the determination of S440, when one or more non-terminated chat windows exist, one or more non-terminated chat windows are transparently displayed on the display unit 151 so as to overlap the list window (S445). Next, the control unit 180 determines whether there is a message transmitted or received in the chat window displayed in S445 (S420), and performs the following steps S420. The displayed chat window may be a chat window displaying messages transmitted and received, or may be an empty chat window in which nothing is displayed. Here, the non-terminated chat window means a chat window in which the end input is not selected among the chat windows executed in S415 or S515 and displayed on the display unit 151. Step S515 will be described in detail with reference to FIG. On the other hand, when the determination result of the S440, if the chat window that has not been terminated, the display unit 151 displays only the list window (S405).

As a result of the determination in S430, when the termination input for the displayed chat window is not selected, the controller 180 determines whether a list window for selecting a third counterpart is selected in operation S450. That is, the controller 180 determines whether a menu for activating the list window is selected to select the third counterpart through the list window. The menu for activating the list window may be displayed in a partial region of the chat window displayed on the display unit 151, or may be displayed in an area other than the displayed chat window on the display unit 151. The third counterpart is one of the conversation partners included in the conversation partner list displayed on the list, and means a third party excluding the conversation partner currently displayed on the display unit 151.

As a result of the determination in S450, when a menu for activating the list window is not selected, the controller 180 determines whether a menu for logging out is selected in operation S475. The menu for logging out may be displayed in a partial region of the list window, or may be displayed in an area other than the list window displayed on the display unit 151. As a result of S475 determination, when the logout menu is selected, the controller 180 terminates the connection with the messenger server for transmitting the instant message. On the other hand, if the logout menu is not selected as the result of the S457 determination, since the chat window and the list window are still displayed on the display unit 151, the controller 180 determines whether there is a message transmitted or received in the chat window displayed on the display unit 151 ( S420), steps S420 and below are performed. The displayed chat window may be a chat window displaying messages transmitted and received, or may be an empty chat window in which nothing is displayed.

In operation S450, when a menu for activating the list window is selected, the controller 180 activates the list window (S455). Activating the list window means that the list window is allowed to be touched or dragged so that a contact displayed on the list window can be selected by touch or drag input through the list window displayed on the display unit 151. do. The activation state is not limited to a touch or drag input. Next, the controller 180 determines whether a third counterpart is selected in the activated list window (S460).

In operation S460, when the third counterpart is selected, the controller 180 hides the chat window currently displayed on the display 180 (S465), and executes the chat window for the selected third party to overlap the list window. The display is transparent on the unit 151 (S470). Next, the controller 180 determines whether there is a message transmitted or received in the chat window displayed on the display unit 151 (S420), and performs the following steps S420. The displayed chat window may be a chat window displaying messages transmitted and received, or may be an empty chat window in which nothing is displayed.

Here, the meaning of hiding the dialog is different from that of ending the dialog in S435. Terminating the chat window in S435 means not only ending the display of the executed chat window but also deleting the message displayed in the chat window. Accordingly, in order to display the terminated chat window on the display unit 151 again, the chat partner must be selected again through the list window, and even if the message is displayed again, an empty chat window in which all previously displayed messages are deleted is displayed. On the other hand, hiding the chat window in S465 only terminates the display of the chat window displayed on the display unit 151, maintains the display of the transmitted and received messages as it is, and displays the list window in order to display the finished chat window on the display unit 151 again. Re-select the chat partner through, or as shown in S445 can be displayed by closing another chat window. When the hidden chat window is called and displayed on the display unit 151, a chat window in which all messages received and hidden after being hidden, as well as messages transmitted and received before being hidden, are displayed. That is, if a chat window selection, end input, and hiding for a specific chat partner is repeated, the chat window for a particular chat partner displays all the messages transmitted and received from the time when the specific chat partner is selected again after the last end input, except that the chat window is If hidden, it is not displayed on the display unit 151.

As a result of the determination at S460, when the third counterpart is not selected, the detailed description will be given with reference to FIG. 5.

As shown in FIG. 5, when the third party is not selected, the controller 180 determines whether a message is transmitted from a third party other than the chat partner of the chat window currently displayed on the display unit 151 (S500). . Here, the third party may be a conversation partner of a hidden chat window, and may be a conversation partner included in a list displayed on the list window.

In operation S505, when the message is transmitted from the third party, the controller 180 displays a message notification display on the display unit 151. The message notification display may be displayed such that a partial area of the chat window displayed on the display unit 151 blinks, or may be displayed as a text indicating that the message is transmitted. Next, the controller 180 determines whether the message notification display is selected by the user (S510). For example, when a touch or drag input occurs through the message notification display displayed on the display unit 180, it may be determined that the message notification display is selected.

For example, when a voice call occurs and a notification display indicating the voice call occurrence is selected, only the call screen is displayed on the display unit 151 during the voice call. Next, the controller 180 determines whether the generated communication event ends (S540). As a result of the determination in S540, if the communication event is not finished, the execution screen of the communication event is continuously displayed on the display unit 151 (S535). On the other hand, when the S540 determination result, when the communication event is finished, the controller 180 ends the display of the execution screen of the communication event, the dialog and the list that was displayed on the display unit 151 at the time when the communication event notification display is selected in the S530 The window is displayed on the display unit 151 again (S545). While the message previously transmitted and received in S545 is displayed again in the chat window displayed on the display unit 151, unlike the case in which the chat window is hidden in S465, the connection with the messenger server is interrupted for a while, so the transmission and reception while the execution screen of the communication event is displayed. Since no message is displayed, the same dialog is displayed when the communication event notification display is selected. Next, the controller 180 determines whether there is a message transmitted or received in the chat window displayed on the display unit 151 (S420), and performs the following steps S420.
