In the present embodiment, the display 2, the display drive circuit 2a, and the like are mounted on the upper stage of the plate-shaped support member 17, and the support member 17 is mounted on the panel housing 20. The support member 17 is provided with a fixing member 17b in a protruding form, and is fixed to the panel housing 20 through the fixing member 17b.

The support member 17 has a quadrangular shape in FIG. 20, but as long as it has a plate-like shape, it does not necessarily have to be limited to the quadrangular shape. The width needs to be wide enough.

21a and 21b are drawings showing a panel housing with a side protective film. FIG. 21a is a schematic view of the panel housing 20 provided with the side protective film 20c, and only the panel housing 20 is shown by omitting other parts for convenience of explanation. In FIG. 21a, the openings are shown by dotted lines.

FIG. 23 is a cross-sectional view of two displays in a state where one side is adjacent to each other. An LCD, which is one of the flat plate displays, is a state in which two substrates composed of an upper plate 15 and a lower plate 15a are assembled facing each other. The surface of the substrate is coated with a transparent electrode 19. Then, there is a liquid crystal layer 15b between both transparent electrodes 19, and polarizing plates 15'and 15a' are attached to the outside of the substrate. Further, when the flat plate display is an EL element, there may be one substrate.

As shown in FIG. 23, sealants 24a and 24b are required to assemble the upper plate 15 and the lower plate 15a and seal the liquid crystal layer 15b. At this time, the sealant 24a at the joint portion 2'is located right beside the pixel electrode 19.

The width of the seam sealant 24a must be as small as possible, for example within 0.8 mm. In addition, a side protective film 20c is attached to the outer corner of the sealant 24a at the joint (when the display is installed in the chassis 16, the side protective film 20c becomes the chassis 16 in the drawing). At this time, the thickness of the side protective film 20c is also made as small as possible, for example, within 0.8 mm. Therefore, in the present invention, when two or more flat display displays are adjacent to each other to form one screen, the joint, which is a non-display area, is within 3.2 mm, and even if the two screens are adjacent to each other, one screen is displayed. Has a viewing effect.

When the main body panel housing 20 and the sub panel housing 40 are combined, the connection detection sensor of the main body panel housing 20 detects the protrusion sensor of the sub panel housing 40, and the central processing unit provided in the main body panel housing 20 has two panels. Automatically detects the coupling state of housings 20 and 40.

FIG. 24 is a block diagram showing a display drive in a state where the main body panel housing 20 and the sub panel housing 40 are combined as a drive block diagram of the display device of the present invention. On the other hand, the multi-display device of the present invention can further enhance the function of the main body when the sub-panel housing 40 is further provided with a storage device such as a memory and is connected to the main body panel housing 20. At this time, the storage device provided inside the sub-panel housing 40 is circuit-connected to the central processing unit of the main body.

In the drawings, the central processing unit 200 is a means for controlling the overall operation of the multi-display device of the present invention. The rom 210 controls the execution program of the display device, the ram 220 stores the data generated during the execution of the program, and the epirom 230 stores the data required by the user and the data necessary for processing the data.

The R / F unit 240 tunes to the RF channel as a radio frequency, amplifies the input audio signal, and changes the RF signal received by the antenna to an intermediate frequency signal. The input unit 250 includes various keys, a menu key, and a selection key, and includes all the button keys 110 in FIG. 1, the input keys 110 in FIG. 26b, and a touch panel that can be installed on the upper stage of the display, and is an input device. It is a comprehensive representation of the functions of.

There are display drive circuits 2a and 4a that drive the display by the output of the central processing device 200, and there are first and second displays 2 and 4 that display information on the screen according to the output signal of the drive circuit (mounted on the main body panel housing 20). The displayed display is called the first display, and the display mounted on the sub-panel housing 40 is called the second display). The drive circuit 4a and the second display are also circuit-wise connected to the central processing unit 200 by the coupling means 22 and 22'.

In addition, a coupling detection sensor 22a is provided to detect that the main body panel housing 20 and the sub panel housing 40 are coupled to each other. Normally, when the panel housings are coupled to each other, the coupling sensing sensor 22a senses the protrusion sensor 44a and sends the sensed signal to the central processing unit 200. That is, the coupling detection sensor 22a is in a state of being opened in a circuit, but when it comes into contact with the protrusion sensor 44a, it is closed in a circuit and a method in which a current flows can be selected. As the coupling detection sensor 22a, various sensors such as an optical sensor can be selected.

FIG. 25 is a desirable display drive control sequence diagram of the present invention, in which the display 2 provided in the main body panel housing 20 and the display 4 provided in the sub panel housing 40 are respectively connected or separated by the main body panel housing 20 and the sub panel housing 40. It is a control sequence diagram which enables selective driving.

When the user turns on the power switch, the radio signal received through the antenna is applied to the central processing unit 200 through the R / F unit 240. Then, when a specific function or the like is set through the input unit 250, the central processing unit 200 executes the set function through the input unit 250 and outputs a signal capable of driving the displays 2 and 4 to the display drive circuits 2a and 4a. Further, the coupling detection sensor 22a detects whether or not the main body panel housing 20 and the sub panel housing 40 are coupled and outputs the output to the central processing unit 200.

The sequence diagram of FIG. 25 will be described based on the circuit configuration as described above. Determine if the power is turned on (310 steps). When the power is turned on, the next step is for the central processing unit 200 to determine if the panel housing is coupled through the coupling sensor 22a (312 steps). That is, it is determined whether or not the main body panel housing 20 and the sub panel housing 40 can be combined.

When the panel housing is connected, it is judged whether to select single screen or simple mode (314 steps). Single screen or simple mode selection is a function selected through the input unit 250. That is, the single screen is a function key that selects only the first display among the first display 2 and the second display 4, and the simple mode selection is a simple calculator or an electronic organizer function that selects all two displays. This function is used when it is not necessary to use it. On the other hand, when receiving materials on the Internet etc., it is necessary to use all two displays. When a single screen function or a simple mode is selected through the input unit 250, such a selection state is output from the input unit 250 to the central processing unit 200. If none of the two function selections is selected, the first and second displays are all driven (316 steps).

On the other hand, when the central processing unit 200 detects from the coupling detection sensor 22a that the panel housing is not coupled, it drives only the first display. Further, even if only one function is selected from the above two function selections, only the first display is driven (318 steps). That is, if even one function is selected in the single screen selection and the simple mode selection, only the first display is driven.

Here, driving only the first display does not mean simply driving only one display, and the display form of the screen is also different from driving all the first and second displays. means. For example, a simple electronic organizer function or sending an electronic mail means that the display form of the screen is different from the display form of the screen for viewing pictures on the Internet. That is, the screen configuration or design for driving one display is different from the screen configuration or design for driving two displays.

Although not shown separately in the block diagram, when the display is an LCD, the power supply to the backlight system can be selectively cut off, so that the user can arbitrarily cut off the power supply to the backlight system. it can. This is possible when the LCD device is mounted on the display device in a semi-transmissive state.

26a and 26b are drawings showing other embodiments of the multi-display device of the present invention. As shown in FIG. 26a, in the present embodiment, the main body panel housing 20 is provided with the auxiliary display 2d, and the auxiliary display 2d can be seen even when the cover 100 is closed. For this purpose, the cover 100 is provided with a cover window 100a. In addition, the main body panel housing 20 has a cover sensor 100b to detect whether the cover 100 can be opened or closed.

FIG. 26b is a drawing in a state where the cover 100 is closed. An input key 110 is provided on the outer surface of the cover 100, and the auxiliary display 2d can be seen through the cover window 100a even when the cover 100 is closed.

Therefore, when the cover 100 is closed, the central processing unit 200 can detect the closing of the cover 100 through the cover sensor 100b so that only the auxiliary display 2d is driven. The operating principle is similar to that of FIGS. 24 and 25.

In this embodiment, for convenience, an example in which two panel housings are connected has been described, but the same can be applied to the same as in this embodiment when three or more panel housings are combined.

If the two panel housings 20, 40 are connected only by the coupling means 22, 22', 44, 44', the physical reliability is weakened.
