OSD controlling system and operation method thereof

1 . An on-screen display (OSD) controlling system for a display device, the OSD controlling system comprising:

a plurality of OSD buttons configured for providing an inputting channel between the display device and a user; and

an OSD menu configured for displaying and adjusting display characteristics of the display device, the OSD menu comprising a plurality of OSD submenus and a primary OSD menu that is configured for displaying first function icons denoting the display characteristics, each of the first function icons corresponding to at least one OSD submenu that is configured for adjusting and setting a parameter value of the corresponding display characteristic, each OSD submenu comprising at least one second function icon;

wherein the at least one second function icon of each OSD submenu corresponds to at least one OSD button, and the at least one second function icon is configured for denoting functions or movements of the corresponding OSD buttons.

2 . The OSD controlling system as claimed in claim 1 , wherein the first function icons comprises a primary menu icon and at least one shortcut icon, the at least one shortcut icon denotes one of the display characteristics and is configured for activating a corresponding OSD submenu, the primary menu icon denotes other display characteristics except the display characteristics coupled with the at least one shortcut icon and is configured for activating corresponding OSD submenus.

3 . The OSD controlling system as claimed in claim 2 , wherein the primary menu icon and the at least one shortcut icon alternatively aligned in a line respectively correspond to the OSD buttons.

4 . The OSD controlling system as claimed in claim 2 , wherein the number of the OSD buttons is calculated according to the formula y≧max {(n+1), m}, wherein y is the number of the OSD buttons, n is the number of the at least one shortcut icon, and m is a maximum value of the number of the second function icons of the OSD submenus.

5 . The OSD controlling system as claimed in claim 2 , wherein the at least one shortcut icon comprises at least one item selected from the group consisting of an auto-adjustment icon, a color enhancement icon, and an audio controlling icon.

6 . The OSD controlling system as claimed in claim 2 , wherein upon the condition that the OSD button corresponding to the at least one shortcut icon or the primary menu icon is pressed, a corresponding OSD submenu is displayed instead of the primary OSD menu.

7 . The OSD controlling system as claimed in claim 1 , wherein the function icons are selected from the group consisting of a confirm icon, an exit icon, at least one pointer icon, an increment icon, and a decrement icon.

8 . The OSD controlling system as claimed in claim 1 , wherein each of the OSD submenus further comprises a function displaying interface configured for displaying graphic icons and characters associated with current display parameter values.

9 . The OSD controlling system as claimed in claim 2 , further comprising a control circuit board configured for sensing movements of the OSD buttons and outputting corresponding signals.

10 . The OSD controlling system as claimed in claim 9 , further comprising a printed circuit board configured for calling and process OSD resources stored therein according to the corresponding signals transmitted from the control circuit board so as to constitute corresponding OSD submenus or the primary OSD menu.

11 . The OSD controlling system as claimed in claim 1 , wherein the display characteristics are selected from the group consisting of brightness, contrast ratio, color temperature, and language.

12 . An on-screen display (OSD) operation method using the OSD controlling system as claimed in claim 1 , the OSD controlling method comprising:

entering the primary OSD menu by operating a selected one of the OSD buttons;

selecting and entering a target OSD submenu by operating a corresponding OSD button that corresponds to a desired first function icon denoting a pre-adjusted display characteristic; and

adjusting a parameter value of the pre-adjusted display characteristic by operating the OSD buttons corresponding to the at least one second function icon of the target OSD submenu.

13 . The OSD operation method as claimed in claim 12 , wherein the OSD controlling system further comprises a control circuit board configured for sensing movements of the OSD buttons and outputting corresponding signals.

14 . The OSD operation method as claimed in claim 13 , wherein the OSD controlling system further comprises a printed circuit board configured for calling and processing OSD resources stored therein according to the corresponding signals transmitted from the control circuit board so as to constitute a corresponding OSD submenu or the primary OSD menu.

15 . The OSD operation method as claimed in claim 14 , further comprising the control circuit board sensing whether the OSD buttons are operated in a predetermined time after the step of entering the primary OSD menu, and wherein if no OSD button is operated in the predetermined time, the primary OSD menu automatically exits displaying.

16 . The OSD operation method as claimed in claim 12 , wherein the first function icons comprising a primary menu icon and at least one shortcut icon, each shortcut icon denotes one of the display characteristic and is configured for activating a corresponding OSD submenu, the primary menu icon denotes other display parameters except the display characteristics coupled with the shortcut icons and is configured for activating corresponding OSD submenus.

17 . The OSD operation method as claimed in claim 16 , wherein the primary menu icon and the at least one shortcut icon respectively correspond to the OSD buttons.

18 . The OSD operation method as claimed in claim 16 , wherein the number of the OSD buttons is calculated according to the formula y≧max{(n+1), (m)}, wherein y is the number of the OSD buttons, n is the number of the at least one shortcut icon, and m is a maximum value of the number of the second function icons of the OSD submenus.

19 . The OSD operation method as claimed in claim 16 , wherein the at least one second function icon is at least one item selected from the group consisting of a confirm icon, an exit icon, at least one pointer icon, an increment icon, and a decrement icon.
