Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a display device, particularly a multi-purpose
The present invention relates to a display device.

[Prior Art I] Display devices having an image display function, such as CRT display devices and flat panel display devices using liquid crystals, plasma, etc., have been used as image output means for a large number of media. However, the traditional display device is for television. Since it is used exclusively for devices such as computers, it is necessary for each device, which poses problems in terms of installation space and cost. As a method to solve this problem, by making the TV tuner pack detachable from the display device,
The applicant of the present invention has already proposed a device in which images from a television, other video, computer, etc. can be selected for display on a display device as needed (for example, Japanese Patent Application No. 160910/1982). This system is configured as shown in FIG. 3, for example. That is, the TV tuner bag 1 has internal functions related to TV broadcast reception, such as a TV tuner circuit and a multiplex broadcast receiving circuit, and a VHF antenna 21. By connecting the UHF antenna 22 to the display body 3 and attaching it to the display body 3, a connection is obtained to the concave passage in the display body 3, thereby making it possible to display television images on the display body. In addition to the TV tuner back 1, it is possible to connect an RGB back, a game back, etc. for obtaining computer images to the display body 3, and by selectively connecting these multiple backs, the display body 3 can be connected.
can be used as a multi-purpose, multi-functional display device. Reference numeral 4 in the figure is a remote control transmitter for remotely controlling the selection function of the function selection device included in the main circuit in the display main body 3. [Problems to be Solved by the Invention] This conventional device has a configuration in which each back is attached to or connected to the display main body 3, so there are restrictions on the types of input/output signals between the display main body 3 and the back. ,
Due to this limitation, the function of the bag and the number of items that can be selected may also be affected.
There was a II limit. In addition, since the TV tuner bag is attached to the display body 3, when using the TV tuner, the bag must be attached to the display body 3, that is, from the viewing position to the display body 3.
It was a hassle to have to go all the way to the location. Further, if the function of the back circuit is improved or the type of the back circuit is increased in comparison with the function of the display main circuit, it may become impossible to attach or connect the display, resulting in a problem of poor versatility. Furthermore, the TV tuner back requires connection with antenna lines, etc., and there is a problem in that the installation location is restricted by these signal lines.

[Means to solve the problem]

In view of the above-mentioned problems, the present invention provides a display device in which an image display driving section and a function selection signal processing section including a built-in television tuner are configured separately and independently, and the signal processing section is configured to drive the image display. The signal processing section is configured to be detachably attached to the display unit and connected via a signal cable, and the signal processing section can be attached to or detached from the display drive section, and the signal processing section can be used to view television and operate function selections. .

【Example】

FIG. 1 is an apparatus configuration diagram showing an embodiment of the present invention. In the figure, an image display drive section 11 and a possible selection signal processing section 12 are constructed separately and independently, and are coupled by a coupling means 13. The image display driving section 11 includes a GRTllz as a display main body, and in addition to a deflection circuit 112 of the CRTll, it also includes a power amplifier 111 as an audio output means. Speaker 114. Headphone jack 116.
It is equipped with an external speaker terminal IIs, etc. The signal processing section 12 has a built-in television tuner 121, and this television tuner 1
It is equipped with a video signal processing circuit 121, etc. for selecting and processing various video signals from 21, etc., and a mixing amplifier 121, etc. as an audio system processing circuit. It is equipped with a control amplifier 124 and the like, as well as a microcomputer 12s (remote control Ill'a and manual switch control) for controlling each switch and processing circuit. The coupling means 13 connects the output terminals of signal processing results such as video signals (RGB), deflection signals, and audio signals from the signal processing section 12 to respective input circuit terminals of the image display driving section 11. The signal processing section 12 is configured to be detachably attached to the image display drive section 11 and connected by a signal cable 131. FIG. 2 shows a connection mode, in which the image display drive section 11 and the signal processing section 12 are connected by a signal cable 131, and the signal processing section 12 is placed at a viewing position, etc. 8 minutes away from the image display drive section 11. located or the image display driver 11
The storage box 132 can be arbitrarily selected. Various signal sources (excluding the TV tuner) to the signal processing unit 12
(video tape recorder, audio equipment, etc.) are connected to the signal processing unit 9 12 by respective dedicated cables. With such a device configuration, the installation position of the signal processing unit 12 is centered on the image display drive unit 11, and the signal cable 1
For example, by installing the signal processing unit 12 at the viewing position, it is possible to easily select various devices such as the TV tuner 121, and the signal processing unit 12 can be selected arbitrarily within the length range of 31. By changing the function of only the section 12, the number of signal sources selected can be made arbitrary. In addition, various signal sources, the signal processing section 12, and the image display drive section 11 are arranged centrally,
Remote control operation is also possible. Further, by installing a remote control receiving section in the signal processing section 12, the signal processing section 12 can be attached to or detached from the drive section 11 for remote control control. Note that it is of course possible to adopt a configuration in which signals are exchanged using light or radio waves from a transmitter/receiver instead of the signal cable.

【Effect of the invention】

As described above, according to the present invention, the display device has an image display driving section and a signal processing section that are separated and detached from each other, so that the signal processing section can be attached to or attached to the image display driving section. Device selection operations can be performed in any state, improving selectivity in usage modes and resulting in a device with excellent operability, as well as being able to easily respond to changes in device selection functions, etc. . In addition, since the TV tuner is built into the signal processing unit, channel presetting can be done at hand.
By using the signal processing section as a Sat, the degree of freedom in installation location increases.
