Description

[Detailed description of the invention]

[Field of Industrial Application] The present invention relates to a display device, and particularly to a multipurpose and multifunctional display device.

[Conventional technology]

2. Description of the Related Art Display devices having an image display function, such as CRT display devices, flat panel display devices using liquid crystal, plasma, etc., have been used as image output means for many 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, the applicant has developed a system in which a function selection device is selected and detached from the display device, so that the display function of the display device can be selected as needed. This has already been proposed (for example, Japanese Patent Application No. 160909/1982). 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. A connection is obtained with the UHF antenna 2z, and by being attached to the display body 3, a connection is obtained with the main body circuit in the display body 3, thereby making it possible to display television images on the display body. In addition to the TV tuner bag 1, the display body 3 has an RGB bag 4 for obtaining computer images, a game bag 5, etc. that can be attached and detached, and by selectively attaching these multiple bags, the display body 3 can be used for multiple purposes and functions. It can be used as a display device. Note that the reference numeral 6 in the figure is a remote control transmitter for remotely controlling the selection function of the function selection device included in the main body circuit in the display main body 3.

[Problems to be solved by the invention]

In this conventional device, since each back is selectively attached to the display body 3 and used, there are restrictions on the types of input/output signals between the display body 3 and the back. There was also a limit to the number of pieces possible. Furthermore, since the back is attached to the display body 3, each time a function is selected, in order to attach or detach the back to the display body 3, it is troublesome to have to go from the viewing position to the position of the display body 3. . Further, if the function of the back circuit is improved or the types of the back circuit are increased in comparison with the function of the display main circuit, it may become impossible to mount the display, resulting in a problem of poor versatility.

[Means for solving the problem 1] In view of the above problems, the present invention configures a display device separately and independently into an image display driving section and a function selection signal processing section, and the signal processing section is configured to display an image. The signal processing section is configured to be detachably attached to the display device drive section and connected by a signal cable, and the signal processing section can be attached to or detached from the display device drive section to perform function selection operations using the signal processing section. [Embodiment] FIG. 1 is a diagram showing the configuration of an apparatus showing an embodiment of the present invention. In this case, the image display driving section 11 and the possible selection signal processing section 12 are constructed separately and independently, and are coupled by a coupling means 13. 1iIf&The display drive section 11 uses a CRT 11. as a display main body. and a deflection circuit 11 of the CRTll. In addition to the power amplifier 11s as audio output means, the speaker 114. headphone jack 11
1. It includes an external speaker terminal 116 and the like. Signal processing section 1
2 is a device selection switch 121 for selecting and fitting various video signals from a television tuner or the like. Video signal processing circuit 12. , RGB composite signal 128. It is equipped with a video signal switching circuit 124, etc., and is also equipped with a mixing amplifier 12z, a control amplifier 126, etc. as an audio processing circuit, and a microcomputer 127 (remote control and manual switch control) for controlling each switch and processing circuit. Equipped with. The combining means 13 receives the video signal (RGB) from the signal processing section 12. In order to connect the output terminals of signal processing results such as deflection signals and audio signals to the respective input circuit terminals of the me display drive section 11, the signal processing section 12 is detachably attached to the image display drive section 11 to connect the signal processing section 12 to the image display drive section 11. The configuration is such that connection is made using a cable 131. FIG. 2 shows a connection mode, in which the image display drive section 11 and the signal processing g12 are connected by a signal cable 131, and the signal processing section 12 is located at a viewing position, etc. separated from the image display drive section 11, or Or the storage box 13 of the image display drive unit 11. It is possible to arbitrarily select which one to attach to. Various signal sources (television tuner, video tape recorder, audio equipment, etc.) to the signal processing section 12 are connected to the signal processing section 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 perform equipment selection operations, and the signal processing, 1li1
By changing the function of only 12, the number of signal sources to be selected becomes arbitrary. Furthermore, various signal sources, the signal processing section 12, and the image display driving section 11 are centrally arranged, and remote control operation is also possible. Further, by providing the signal processing section 12 with a remote control receiving section, the signal processing section 12 can be attached to and detached from the drive section 11 and controlled by remote 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 is configured so that the image display driving section and the signal processing section are separated and independent. Because it is removable, the signal processing section can perform device selection operations in any state attached to or attached to the image display drive section, improving selectivity in usage modes and providing excellent operability. In addition to this, it also has the effect of easily responding to changes in equipment selection functions, etc.
