Abstract:
1. An apparatus for controlling a screen of an image display device having at least three frame rate determination ways including a first frame rate determination way, a second frame rate determination way, and a third frame rate determination way, the apparatus comprising: a user interface configured to receive a command from a user; a power unit configured to supply a power; a display module configured to be operated when the power is supplied through the power unit; a mode determining unit configured to determine a mode of an input image signal among a TV mode, a PC mode and an other mode; and a screen controller configured to determine one among the at least three frame rate determination ways based on the determined mode, to apply the determined frame rate determination way to the display module and to control the display module such that a frame rate of the display module is automatically set according to the determined frame rate determination way, wherein, if the determined mode is the TV mode, the first frame rate determination way is applied so that the screen controller is configured to set the frame rate to be 100 Hz or 120 Hz, wherein, if the determined mode is the PC mode, the second frame rate determination way is applied so that the screen controller is configured to detect a variation of motion of the screen displayed on the display module and to set the frame rate based on the detected variation of motion of the screen, and wherein, if the determined mode is the other mode, the third frame rate determination way is applied so that the screen controller is configured to display an on screen display (OSD) menu for manually selecting the frame rate and set the frame rate based on a user input on the displayed OSD menu.
