Abstract

A display apparatus correctly detecting a rotated position of a display part and automatically displaying a rotated picture according to rotation of the display part. The display apparatus has a display part displaying a picture based on a video signal thereon; a video signal processing part transmitting the video signal to the display part; a rotating position detector including a mass body, a housing having a plurality of pockets in which the mass body is selectively retained according to a rotated position of the display part, and a plurality of contact sensors respectively placed in the pockets and generating a contact signal upon contact with the mass body; and a controller controlling the video signal processing part so as to display a rotated picture according to the rotated position of the display part based upon the contact signal from the rotating position detector.

Claims

1. A display apparatus comprising:

a display part displaying a picture based on a video signal thereon;

a video signal processing part transmitting the video signal to the display part;

a rotating position detector comprising a mass body, a housing having a plurality of pockets in which the mass body is selectively retained according to a rotated position of the display part and a guiding projection part inwardly protruding from an inside wall of the housing between two adjacent pockets guiding the mass body to one of the packets and contact sensors respectively placed in the pockets and generating a contact signal upon contact with the mass body; and

a controller controlling the video signal processing part so as to display a rotated picture according to the rotated position of the display part based upon the contact signal from the rotating position detector.

2. A display apparatus comprising:

a display part displaying a picture based on a video signal thereon;

a video signal processing part transmitting the video signal to the display part;

a rotating position detector comprising a mass body, a housing having a plurality of pockets in which the mass body is selectively retained according to a rotated position of the display part, and contact sensors respectively placed in the pockets and generating a contact signal upon contact with the mess body; and

a controller controlling the video signal processing part so as to display a rotated picture according to the rotated position of the display part based upon the contact signal from the rotating position detector, wherein the mass body is in a ball shape.

3. A rotating position detector of a display apparatus having a display part displaying a picture, comprising:

a mass body;

a housing having pockets in which the mass body is selectively retained according to a rotated position of the display part and a guiding projection part inwardly protruded from an inside wall of the housing between two adjacent pockets guiding the mass body to one of the pockets; and

a plurality of contact sensors each placed in the pockets and generating a contact signal upon contact with the mass body.

4. A rotating position detector of a display apparatus having a display part displaying a picture, comprising:

a mass body,

a housing having pocket in which the mass body is selectively retained according to a rotated position of the display part; and

a plurality of contact sensors each placed in the pocket and generating a contact signal upon contact with the mass body, wherein the mass body is in a ball shape.

5. A portable computer system having a main body and a display apparatus, comprising:

a video signal processing part transmitting a video signal to the display part
