Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device, and more particularly to a display device having a wide-screen display section and capable of displaying a received video of a television broadcast program or the like.

[0002]

2. Description of the Related Art A display device for displaying a received image such as a television broadcast program is equipped with a display unit for a wide screen having an aspect ratio of 16: 9 and a normal screen having an aspect ratio of 4: 3. There is.
In the conventional analog television broadcasting, a video wave corresponding to the normal screen is transmitted from a broadcasting station, and a display device including the display unit for the normal screen which receives the video wave receives a normal wave. The received image on the round screen is displayed faithfully.

Further, in the display device having the display unit for the wide screen, the image radio wave corresponding to the wide screen is received, and the image corresponding to the wide screen such as the high-definition image is projected, so that the image is realistic. You can enjoy it. Further, in the display device, a mode for displaying an image for a normal screen and a normal screen size are displayed.
Wide mode, which stretches a screen of a normal screen size horizontally and enlarges it to fill the wide screen, or a normal screen size image is expanded to a wide aspect ratio of 4: 3. Zoom in to full size
Some are equipped with a function to switch between various screen modes such as Mu mode.

However, with the rapid progress of digitization in recent years, the standard of high-definition broadcasting has been changed from a conventional analog system to a digital system,
Digital broadcasting such as digital high-definition broadcasting
It is becoming for the screen.

On the other hand, in a vehicle-mounted display device, it is necessary to display a wide range of information such as map data in the navigation function and the like in as much detail as possible, and in order to improve the visibility, it -A display device is used that has a display unit for a wide screen rather than for a round screen.

[0006]

When a normal screen image is enlarged and displayed in a wide mode in a display device having a wide screen display section, the image is projected in a horizontally distorted state. The viewer feels strange. Further, when the image is enlarged and displayed in the zoom mode, the upper and lower parts of the image are not displayed, and the original image is not faithfully reproduced. For this reason, even with a display device having a wide-screen display unit, many viewers normally see the normal screen mode.

When a normal screen is displayed on a display device having a wide-screen display section as described above, a black mask section is inevitably formed on both sides of the display section. However, there is a problem that this mask portion is wasted.
