Subsequently, after the determination result (S25), the number of sub-screens is input as much as the number to be changed (S25).

On the other hand, the determination result (S16), if the user enters a command other than the Undo / Redo (Redo) command to determine whether or not the menu setting command (S26).

Subsequently, when the user selects a menu setting command, the determination result (S26) determines whether or not the color temperature change menu is selected (S27).

As a result of the determination (S27), when the user selects the color temperature change menu, the user changes to the desired color temperature (S28).

On the other hand, if the user selects the contrast change menu (S26), the user changes the contrast to the desired contrast (S29 to S30).

In addition, if the user selects the brightness change menu (S26), the user changes the brightness to the desired brightness (S31 to S32).

As a result of the determination (S26), when the user selects a color change menu, the user changes the color to the desired color (S33 to S34).

As a result of the determination (S26), when the user selects the tint changing menu, the user changes the desired tint (S35 to S36).

As a result of the determination (S26), if the user wants to change the sharpness (sharpness), the user changes to the desired sharpness (sharpness) (S37 to S38).

In operation S39, the changed menu condition is applied to the main screen.

Subsequently, if the user wants to save the changed screen, the changed condition is stored in the memory and ends (S40 to S41).

As described above, the screen setting method of the digital TV according to the present invention reads the screen setting information previously stored in the memory when the TV system starts, applies it to the main screen, and sets the sub-screen applying the default value.

And if the user wants to change the screen information setting, the user wants to undo (Undo) or redo depending on whether he wants to undo (Undo) function in the history if the currently changed history is valid. Reads the screen setting information from the previous step history from the memory, shows the screen phenomenon that appears when the setting information is applied to the subscreen or multiple screens, and displays the setting information if the user wants to save it. Applies to the information processor, applies the main screen, and saves the currently changed information in the memory.

In addition, if the user wants a redo function and the current history is valid, the screen setting information on the history of the next step is read from the memory as opposed to the Undo, and is displayed as a single subscreen or a plurality of subscreens. If the setting information is applied, the screen state to be shown is shown, and if the user wants to save it, the setting information is applied to the screen information processor, the main screen is applied, and the currently changed information is stored in the memory.
