`ABSTRACT
`
`The present invention provides a display device which
`includes at least one module mounting frame which is
`mounted on a display device mounting strncture, a plurality
`of display modules which are detachably mounted on the
`module mounting frame and constitute a display screen. a
`signal cable which has a wiring route in the inside of the
`module mounting frame and is detachably connected to the
`display modules and supplies image signals to the display
`modules, and a power source cable which has a wiring route
`in the inside of the module mmmting frame and is detach(cid:173)
`ably c01111ected to the display modules thus supplying elec(cid:173)
`tric power to the display modules. Due to such a constitu(cid:173)
`tion. it is possible to realize the reduction
`and the
`lowering of the manufacturing cost.

`
`DISPLAY DEVICE ASSEMBLING METHOD AND
`DISPLAY DEVICE
`
`BACKGROUND OF THE INVENTION
`
`[0001] 1. Field of the Invention
`
`[0002] The present invention relates to an assembling
`method of a display device which constitutes a display
`screen using a plurality of display modules, and a display
`device which constitutes a display screen using a plurality of
`display modules, and more particularly to an assembling
`method of a display device which is preferably used out(cid:173)
`doors and such a display device.
`
`[0003] 2. Description of the Related Art
`
`[0004] With respect to a display device such as conven(cid:173)
`tional live broadcasting large-sized outdoor display device
`or an advertisement large-sized display device, for example,
`as described in JP-A-4-110992, JP-A-2004-341468 and the
`like, a display screen is constituted of a plurality of display
`modules.
`
`[0005] Although the whole constitutions of these struc(cid:173)
`tures are not shown in these publications, the typical whole
`constitution of the structure of the display device used
`outdoors such as the live broadcasting large-sized outdoor
`display device, the advertisement large-sized display device
`or the like, is shown in FIG. 22, for example.
`
`[0006] FIG. 22 shows an example of the conventional
`typical large-sized display device as a right side view. As
`shown in the drawing, the conventional typical large-sized
`display device has, in general, the structure in which in the
`inside of a waterproof outer casing le having the waterproof
`structure, a large number of support colunms ld, a large
`number of display modules xx which are mounted on the
`large number of support colunms ld, a display controller 2
`which controls a screen display on the whole display screen
`which is constituted of the large number of display modules
`xx, a power source for these parts (omitted from the draw(cid:173)
`ing) and the like are incorporated.
`
`[0007] Further, in the conventional typical large-sized
`display device, the weight support structure is, as can be
`estimated also from FIG. 22, the self-completing or self(cid:173)
`standing structure in which the waterproof outer casing le
`receives all weights consisting of the total weight of the
`large number of support colunms ld, the total weight of the
`large number of display modules xx, the total weight of
`electric circuit constituting parts such as the display con(cid:173)
`troller 2, the power source, various cables for electric
`power/control signals, and the weight of the waterproof
`outer casing le per se.
`
`[0008]
`In the conventional large-sized display device, the
`weight support structure, as illustrated in FIG. 22, is the
`self-completing or self-standing structure in which the
`waterproof outer casing le receives all weights consisting of
`the total weight of the large number of support colunms ld,
`the total weight of the large number of display modules xx,
`the total weight of electric circuit constituting parts such as
`the display controller 2, the power source, various cables for
`electric power/control signals, and the weight of the water(cid:173)
`proof outer casing le per se. Accordingly, the weight support
`structure has an advantage that the sufficient waterproof
`structure is applied to the electronic equipment in the inside
`
`of the structure and hence, the weight support structure can
`be installed in any arbitrary environment. On the other hand,
`the waterproof outer casing le per se is required to possess
`the sufficient strength and reliability thus pushing up a
`weight and a manufacturing cost of the whole display
`device.
`
`SUMMARY OF THE INVENTION
`[0009] The present invention has been made in view of the
`above-mentioned circumstances and it is an object of the
`present invention to reduce a weight and a manufacturing
`cost of a display device per se.
`
`[0010] The present invention is directed to an assembling
`method of a display device which constitutes a display
`screen using a plurality of display modules, wherein the
`display device is assembled by a waterproof frame mounting
`step which mounts a waterproof frame on a display device
`mounting structure, and a display screen assembling step
`which assembles the display screen whose periphery is
`covered with the waterproof frame mounted on the display
`device mounting structure using a plurality of display mod(cid:173)
`ules. Here, since a weight of the waterproof frame of the
`display device is received by the display device mounting
`structure, and a weight of the plurality of display modules
`which constitute the display screen is also received by the
`display device mounting structure and hence, a weight
`resistance strength of the display device per se can be
`reduced thus realizing the reduction of weight and the
`lowering of manufacturing cost of the display device per se.
`
`[0011] Further, the present invention is directed to an
`assembling method of a display device which constitutes a
`display screen using a plurality of display modules, wherein
`the display device is assembled by a module mounting frame
`mounting step which mounts a module mounting frame on
`a display device mounting structure, a display module
`mounting step which mounts the display modules on the
`module mounting frame, and a display screen constituting
`step which constitutes the display screen using the plurality
`of display modules by exercising the display module mount(cid:173)
`ing step plural times. Here, a weight of the module mounting
`frame of the display device is received by the display device
`mounting structure, and a weight of the plurality of display
`modules which constitute the display screen is also received
`by the display device mounting structure by way of the
`module mounting frame and hence, a weight resistance
`strength of the display device per se can be reduced thus
`realizing the reduction of the weight and the lowering of the
`manufacturing cost of the display device per se.
`
`[0012] Further, the present invention is directed to a
`display device which includes at least one module mounting
`frame which is mounted on a display device mounting
`structure, a plurality of display modules which are detach(cid:173)
`ably mounted on the module mounting frame and constitute
`a display screen, a signal cable which has a wiring route in
`the inside of the module mounting frame and is detachably
`connected to the display modules and supplies image signals
`to the display modules, and a power source cable which has
`a wiring route in the inside of the module mounting frame
`and is detachably connected to the display modules thus
`supplying electric power to the display modules. Due to such
`a constitution, it is possible to realize the reduction of
`weight, the lowering of the manufacturing cost and the
`waterproof of the display device per se.

`
`[0038] A display system which allows a large-sized dis(cid:173)
`play device used in the embodiment 1 of the present inven(cid:173)
`tion to perform a display is not a particular system and is a
`display system which has been used generally convention(cid:173)
`ally for allowing a large-sized display device whose display
`screen is constituted of a plurality of display modules such
`as a live broadcasting large-sized outdoor display device, an
`advertisement large-sized display device or the like to per(cid:173)
`form a display can be used. With respect to the display
`system which has been generally used conventionally, vari(cid:173)
`ous systems have been considered specifically. As the sys(cid:173)
`tem constitution of one example out of these respective
`systems, an example of the display system in the embodi(cid:173)
`ment 1 of the present invention is shown in FIG. 1.
`
`[0039] With respect to the display system shown in FIG.
`1, as illustrated in the drawing, in the display device 1, a
`display screen 10 is, as is well known, constituted by
`arranging a large number of display modules 11, 12, ... ln,
`21, 22, ... 2n, ... ml, m2, ... nm in a matrix array, that
`is, in the row direction (lateral direction) and in the column
`direction (longitudinal direction).
`[0040]
`In the display device 1 having such a constitution,
`as is well known, an image display control signal and an
`image information signal are supplied from a display con(cid:173)
`troller 2 by way of buffer memories 31, 32, ... 3n formed
`for every row.
`
`[0041] The above-mentioned display controller 2 pos(cid:173)
`sesses, as is well known, a function 21 of TV (television)
`signal processing which processes image information from
`a video system 4, a function 22 of graphic processing which
`processes image information from a computer system 5, and
`a function 23 of character information processing which
`processes character information from the computer system
`5. As is well known, the controller 2, based on information
`from the video system 4 and information from the computer
`system 5, supplies predetermined image display control
`signals and image information signals to the display mod(cid:173)
`ules 11, 12, ... ln, 21, 22, ... 2n, ... ml, m2, ... mn of
`the display device 1 so as to allow the whole display screen
`10 to display a predetermined image such as a live broad(cid:173)
