Control apparatus and method of display device

An OSD control apparatus of a display device coupled to a computer, comprising:

• an OSD module which is installed in the display device and generates a menu screen signal to set display state information according to an OSD control command;
• an interface unit which performs data communications between the display device and the computer;
• a computer input unit by which OSD control information for controlling an OSD menu of the display device is input to the OSD module through the interface unit;
• a computer control unit which receives OSD state information indicating an output state of the OSD menu screen through the interface unit, and sends the OSD control information to the interface unit to control the OSD menu of the display device corresponding to the OSD control information input from the computer input unit;
• and
• a display control unit which controls the OSD module according to OSD control information of the computer that is received through the interface unit, and outputs the OSD state information indicating the output state of the OSD menu screen to the computer through the interface unit.

A method of controlling an OSD module installed in a display device coupled to a computer, comprising:

• determining whether OSD control information of the computer is outputted through an interface unit while performing data communications between the display device and the computer;
• analyzing the OSD control information, and generating a control command to control the OSD module, corresponding to an analyzed result;
• and
• controlling the OSD module according to the control command.

A method for controlling a display device coupled to a computer comprising:

• determining whether control information of the computer is outputted through an interface unit, while performing communications with the computer;
• analyzing the control information, and generating a control command to control a predetermined function of the display device corresponding to an analyzed result;
• and
• controlling the predetermined function of the display device according to the control command.

A method in an OSD control apparatus of a display device generating an OSD menu screen and communicating with a computer, comprising:

• causing an interface unit to be connected between the display device and the computer;
• outputting OSD state information to the computer through the interface;
• receiving OSD control information from the computer through the interface unit;
• and
• generating an OSD control command to control the OSD menu screen according to the OSD control information.

A recording medium encoded with data readable by a computer to implement a method of generating an OSD menu screen in an OSD control apparatus of a display device communicating with the computer through an interface unit having a USB port, the recording medium comprising:

• data used to output OSD state information to the computer through the interface;
• data used to receive OSD control information from the computer through the interface unit;
• data used to generate an OSD control command to control the OSD menu screen according to the OSD control information;
• data used to receiving event information from the computer through the interface unit;
• and
• data used to generate setting values to control the OSD menu screen according to the event information.
