DISPLAY HAVING UNSHIELDED OSD AND METHOD FOR IMPLEMENTING UNSHIELDED OSD
First Claim
1. A displayer having an unshielded on screen displayer (OSD), suitable for receiving a video signal and generating an OSD to avoid shielding a viewable area of a screen, comprising:
- a screen, for displaying a video image according to the video signal;
a microprocessor, for executing the following procedures;
generating a plurality of first opaque items without a background color and a first background layer with a size the same as that of the first opaque items without the background color; and
overlapping the first background layer with one of the first opaque items without the background color, and combining the first opaque item without the background color with the first background layer into a function menu;
a video processor, for receiving the function menu from the microprocessor, and displaying the function menu on the video image; and
a controller, provided for a subscriber to transmit the following control signals;
sending an acknowledgement signal, for instructing the microprocessor to execute a function indicated by an acknowledged first opaque item without the background color; and
sending a function select signal, for moving the first background layer to display the first background layer with overlapping another first opaque item without the background color.

Abstract
A displayer having an unshielded on screen displayer (OSD) and a method for implementing the unshielded OSD are described. A microprocessor of the displayer having the unshielded OSD generates a plurality of first opaque items without a background color and a first background layer having a size the same as that of the first opaque items, and combines the first opaque items with the first background layer into a function menu. When a controller controls the first background layer to move around, the first background layer is overlapped with one of the first opaque items without the background color, and taken as an undercoat for the first opaque item, so as to highlight the information carried by the first opaque item. The first opaque item without the background color does not easily shield the screen image, so as to avoid shielding a viewable area of the screen.

-
a screen, for displaying a video image according to the video signal; a microprocessor, for executing the following procedures; generating a plurality of first opaque items without a background color and a first background layer with a size the same as that of the first opaque items without the background color; and overlapping the first background layer with one of the first opaque items without the background color, and combining the first opaque item without the background color with the first background layer into a function menu; a video processor, for receiving the function menu from the microprocessor, and displaying the function menu on the video image; and a controller, provided for a subscriber to transmit the following control signals; sending an acknowledgement signal, for instructing the microprocessor to execute a function indicated by an acknowledged first opaque item without the background color; and sending a function select signal, for moving the first background layer to display the first background layer with overlapping another first opaque item without the background color. - View Dependent Claims (2, 3, 4, 5)

6. A method for implementing an unshielded OSD, wherein the OSD is displayed on a video image of a displayer screen, the method comprising:
-
receiving an OSD displaying signal transmitted from a controller and then generating a plurality of first opaque items without a background color and a first background layer with a size the same as that of the first opaque items without the background color; overlapping the first background layer with one of the first opaque items without the background color, and combining the first opaque item without the background color with the first background layer into a function menu; displaying the function menu on the video image; and executing a function corresponding to a control signal according to the received control signal; moving the first background layer to be displayed by overlapping another first opaque item without the background color, if the control signal is a function select signal; and instructing the microprocessor to execute a function indicated by an acknowledged first opaque item without the background color, if the control signal is an acknowledgement signal. - View Dependent Claims (7, 8, 9, 10)
