Abstract

An audio-video (AV) device for a vehicle includes a display panel including a display unit and a pattern unit arranged on edges of the display unit; and a display board disposed on a rear face of the display panel. The display board includes at least one wireless antenna located outside of the display unit, an antenna module, and a connector.

Claims

1. An audio-video (AV) device for a vehicle comprising:

a display panel including a display unit and a pattern unit arranged on edges of the display unit; and

a display board disposed on a rear face of the display panel,

wherein the display board includes at least one wireless antenna located outside of the display unit, an antenna module, and a connector.

2. The AV device of claim 1, wherein:

the display board further includes a projection part protruding to a side of the display panel, and

the at least one wireless antenna is disposed on a front of the projection part.

3. The AV device of claim 1, wherein:

the pattern unit includes a wire unit having a plurality of wires arranged along outer edges of the display unit and a connection unit located on a side of the display unit connecting the plurality of wires to the display board,

the display board further includes a projection part protruding to a side of the display unit, and

the at least one wireless antenna is disposed on a front of the projection part.

4. The AV device of claim 1, wherein:

the at least one wireless antenna is fixed on a front face of the display board,

the antenna module and the connector are fixed on a rear face of the display board, and

the display board further includes a first antenna wire unit electrically connecting the wireless antenna to the antenna module and a second antenna wire unit electrically connecting the antenna module to the connector.

5. The AV device of claim 4, wherein the connector is connected to another connector to be electrically connected to a main board contained inside of a chassis.

6. The AV device of claim 1, wherein the at least one wireless antenna includes at least one of a Wi-Fi antenna and a Bluetooth antenna.

7. The AV device of claim 1, wherein the at least one wireless antenna includes a Wi-Fi antenna and a Bluetooth antenna.

8. The AV device of claim 7, wherein the antenna module is configured to process signals input from the Wi-Fi antenna and the Bluetooth antenna together.

9. The AV device of claim 2, wherein:

the at least one wireless antenna includes a first wireless antenna disposed at an end of the projection part and a second wireless antenna disposed at another end of the projection part, with respect to a center of the display unit, and

the display board further includes a first antenna wire unit electrically connecting the at least one wireless antenna to the antenna module and a second antenna wire unit electrically connecting the antenna module to the connector.

10. The AV device of claim 2, wherein the projection part is formed to be longer than a length of the side of the display panel and protrude outwardly from both sides of the display panel.

11. The AV device of claim 2, wherein the projection part includes a first projection part protruding to one side from the display panel and a second projection part protruding to another side from the display panel.

12. The AV device of claim 11, wherein the first and second projection parts protrude at opposite locations.

13. The AV device of claim 12, wherein the at least one wireless antenna includes a first wireless antenna disposed at an end of the first projection part and a second wireless antenna disposed at an end of the second projection part diagonally opposite to the end of the first projection part.

14. The AV device of claim 11, wherein:
