Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laptop-type liquid crystal display device having a large liquid crystal display, which can be used for both games and televisions.

[0002]

2. Description of the Related Art As an example of a conventional game machine, as shown in FIG. 15, an IC card 201 which is game software in which a predetermined program is stored in a connector (not shown) arranged inside the game machine main body 200. Is the game console body 200
The game machine main body 200 does not have a display means, and is connected to a home TV 204 through a connection cable 203 to output video and audio. . Further, the operation unit as a game is configured such that the keypad 205 is detachably attached to the game machine main body 200. Further, an AC adapter 206 for supplying power is also connected to the game machine main body 200, and a game can be played. As another example of the conventional game machine, as shown in FIGS. 16 and 17, a liquid crystal display 210, a main electric circuit (not shown), a connector (not shown) for mounting the IC card 201, Dry battery 21 as a power source
1. The game operation keys 212, 213, and 214 are integrally formed on the game machine main body 215, and the IC card 201
May be marketed as a handy type game machine configured to be detachable from the through hole 216 of the game machine body 215.

[0003]

In the above prior art,
First of all, in the former case, many things are connected to the main body of the game machine, especially because the home TV is used as the display section, the whole apparatus becomes a large-scale thing, and portability is poor,
It needs a space to store it when not in use, and
If it is stored separately, it may be lost due to the large number of components. AC adapter, keypad, TV
There are many parts that need to be connected, such as connection cables to the game console, especially when connecting a game console to a home TV, and the connection terminals on the home TV side are very many in recent AV compatible TVs. I often feel it,
It wasn't good to use. Also, as the number of objects to be connected increases, the number of times of attaching and detaching with the game machine body increases, and the connection parts (particularly the cords) and the game machine body side become durable and easily broken, and there is also the problem that maintenance costs are high. there were. Next, in the latter conventional example, it is necessary to reduce the weight in order to make it a handy type, and the liquid crystal display body must use a small size object, and detailed characters such as character information of game software and TV appear. Sometimes it was unreadable. Moreover, such a handy type game machine cannot receive a television signal,
Because you can only play games, it feels expensive. In order to avoid this, a tuner is prepared as a separate body, and there are also things that are connected to the game console itself, but the high cost and separate handicap characteristics that result from the separate configuration.

[0004]
