[Prior Art] As a conventional display panel of this type, one of the type shown in FIG. 10 has been common. That is, the display panel 30 has a display substrate 32 whose main surface is covered with a display film 31 on which characters, symbols, figures, pictures, etc. are displayed. The display substrate 32 is made of a material with excellent mechanical strength, such as metal or synthetic resin, and has openings 33 at a plurality of locations on its main surface. A lighting unit 34 is installed on the back side through the opening 33.
The structure is such that the characters and the like on the display film 31 are displayed by illumination.

The front surface of the display film 31 is covered with a transparent acrylic plate 35, etc., and the display substrate 32 and display film 31 described above are covered with this acrylic plate 3.
5 and their peripheral edges are integrally held and fixed to each other by a metal frame 36.

[Problems to be solved by the invention] By the way, in the display panel structure described above, as explained above, a single metal plate or synthetic resin plate is generally used as the display substrate 32; When manufacturing display panels with different display scales, it is necessary to prepare display substrates 32 with dimensions corresponding to the display scales each time.

The present invention was developed in view of the above problems, and its purpose is to provide a technology for connecting display substrates that has a high degree of freedom in setting the display scale and allows units such as illumination units to be attached to arbitrary positions. It's about doing.

[Means for Solving the Problem] The present invention comprises two or more rectangular panel-shaped display substrate cells in which through holes are successively arranged in a matrix at regular intervals over the entire surface, and each of the display substrate cells. The display substrate is made up of joint members that are connected to each other in a planar direction, and each of the display substrate cells has a part of the display substrate cell arbitrarily arranged in the thickness direction from the peripheral edge to an arbitrary through hole position in the inner direction. The joint member is formed by cutting out a thickness of , and has a concave portion that is continuous when one side of each display substrate cell is in contact with each other, and the joint member is composed of a joint body and an engaging portion, and the joint body is formed in a planar shape that is substantially the same as the planar shape of the concave portion that is in a continuous state with one side of each display substrate cell in contact with each other, and has a wall thickness that substantially matches the depth of the concave portion, and furthermore, and a through hole corresponding to the through hole in the recess in the continuous state, and when the joint member is fitted into the recess in the continuous state and the display substrate cell and the joint member are fixed by the engaging part. Through holes are continuously provided at regular pitch intervals across at least the front surfaces of the main surfaces of two or more display substrate cells.

[Function] According to the above-described means, the joint body of the joint member is formed to have substantially the same planar shape as the recessed portion in which one side of each display substrate cell is in contact with each other and is in a continuous state, and the above-described Since it has a wall thickness that approximately matches the depth of the recess, when the joint member is fitted into the continuous recess and the display substrate cell and the joint member are fixed by the engaging portion, the joint body and the display substrate cell are The joint body is located on the same plane as the main surface, and the joint main body is provided with a through hole that faces the through hole in the concave portion that is in the continuous state, so that when the display substrate cells are combined, the through hole are arranged consecutively at a constant pitch on at least the front surface of the main surface.

As a result, it is possible to mount various units such as a display body even at the joining part of the display substrate cell.

Furthermore, by connecting a plurality of display substrate cells in a planar direction via joint members, it is possible to provide a display substrate with a high degree of freedom in setting the display scale.

[Example] Fig. 1 is a partial plan view showing a combined state of a display substrate cell and a joint according to an embodiment of the present invention, Fig. 2 is a cross-sectional view taken along the - line in Fig. 1, and Fig. 3 is a diagram showing a display. A perspective view showing the formation state of the recessed portion of the substrate cell,
FIG. 4 is a plan view showing a single display substrate cell;
The figure is a front view thereof, FIG. 6 is a plan view showing the joint member of this embodiment, and FIG. 7 is a front view similarly showing the joint member.

The display substrate of this embodiment has a rectangular panel shape as shown in FIG. 4, which constitutes a single display substrate cell 1, and these display substrate cells 1 are connected in the vertical and horizontal directions by the required number. This constitutes a display substrate.

The display substrate cell 1 is obtained by integrally molding a material with excellent mechanical strength, such as a synthetic resin such as polycarbonate mixed with about 30% glass, using a mold, etc., and has a square shape in its plane. The holes 2 are arranged in a matrix over the entire surface of the plate. These through holes 2 are formed at a constant pitch interval P, for example, about 5 mm, with the center of the hole as a reference, and one side of the opening is about 3 mm in plan section.

By the way, in the vicinity of each peripheral edge of the display substrate cell 1, a third
A recess 3 as shown in the figure is formed. The recess 3 enters inward from the peripheral end surface of the display substrate cell 1, and cuts the display substrate cell 1 to an arbitrary thickness in the thickness direction up to the position of the second through hole 2a counting from the peripheral end. It is formed to extend in a rectangular planar shape. Therefore, when the two display substrate cells 1, 1 are arranged in parallel on the same plane with their peripheral end surfaces in contact with each other, the recesses 3 are also located in corresponding positions at the respective peripheral ends. Therefore, both the recesses 3, 3 are in a continuous state.

In addition, around the second through hole 2a,
The wall portion of one side of the peripheral end side from which the through hole 2 is to be separated is cut out to the middle of the thickness direction of the display substrate cell 1. On the other hand, in FIG. 3, the through holes 2b and 2c which are vertically adjacent to the through hole 2a are formed so that the wall thickness _d1 of one side near the peripheral end is thinner than the wall thickness _d2 of the other part. It is in a state of being As shown in FIG. 2, this thinly formed wall portion _d1 has a step 4 in which the wall thickness becomes even thinner near the other surface, and the step 4 is a fitting claw of a joint member 5, which will be described later. It has a structure that engages with the engagement protrusion 10 of No. 8.

As shown in FIG. 6, the joint member 5 has shoulder portions 7 provided perpendicularly to the joint body 6 at both ends of the joint body 6, and its overall planar shape is H-shaped. It is configured so that Thus, the joint main body is formed into a planar rectangular shape that is substantially the same as the planar shape of the recesses 3, 3, which are in a continuous state with the two display substrate cells 1, 1 in contact with each other with their peripheral end surfaces. At the same time, the recess 3
It has a wall thickness that approximately corresponds to the depth of .

Further, the joint body 6 has a through hole 2b corresponding to the through hole 2 in the recessed portions 3, 3 which are in a continuous state with the two display substrate cells 1, 1 in contact with each other with their peripheral end surfaces. In addition to the above-mentioned both shoulder portions 7
A pair of engaging pawls 8 as shown in FIG. 7 extend from there. The pair of engagement claws 8 have engagement protrusions 10 at their tips in the direction of the other engagement claws 8 . The joint member 5 having such a structure is obtained, for example, by integrally molding a synthetic resin such as polycarbonate mixed with glass using a mold or the like, similar to the display substrate cell 1 described above.

Here, a method of connecting the display substrate cells 1 using the joint member 5 will be explained as follows.

First, as shown in FIG. 1, two display substrate cells 1, 1 are arranged in parallel on the same plane with their peripheral end surfaces in contact with each other. At this time, since the above-described recesses 3 are also in corresponding positions at the respective peripheral ends, both recesses 3 are in a continuous state. In this state, the joint member 5 is connected to the display substrate cell 1 by the engaging claw 8.
Apply force in the vertical direction while facing the side. At this time, the engaging claw 8 enters into the display substrate cell 1 along the inner wall surface of the wall thickness d ₁ explained above, and finally the engaging claw The engagement protrusion 10 of No. 5 is in a state of being fitted into the step 4 of the wall portion. In this state that the entire joint member 5 is completely fitted into the recesses 3, 3, the depth of the recess 3 and the thickness of the joint main body 6 are approximately the same, so that
As shown in FIG. 2, the main surface of the joint body 6 is located on the same plane as the main surface of the display substrate cell 1.

On the other hand, the shoulder portions 7, ₇ of the joint member 5 compensate for the wall thickness d1 of the thin wall portion, resulting in the same wall thickness as the wall thickness _d2 of the other wall portions. As described above, the joint main body 6 has a through hole 2 corresponding to the through hole 2 in the concave portion 3, which is continuous with the two display substrate cells 1, 1 in contact with each other with their peripheral end surfaces. Since the holes 2b are provided, the continuous arrangement of the through holes 2 at a constant pitch interval P is maintained even in the connecting portion.

In this way, by connecting a required number of display substrate cells 1 in the same plane direction using the joint members 5, a display substrate having a desired display scale can be formed.

Next, display substrate 1 configured as above
A brief explanation of examples of a free mount display panel and a mosaic display panel using 1 is as follows.

FIG. 8 shows an example in which the display substrate of this embodiment is applied to a free mount display panel, and a display unit 12 is mounted on the main surface side of the display substrate 11 connected and formed as described above. This display unit 12
The lamp module 13 includes a lamp module 13 containing a light emitting source such as a light emitting diode (not shown), a separate plate 14 that partitions the illumination range in the lamp module 13, and a filter 15 attached to the front surface of the opening of the lamp module 13. The filter 15 is made of a transparent synthetic resin plate treated with a light-scattering agent to give it a milky white color, or a plate treated with green, red, or other coloring agents. The structure is such that it is selectively used depending on the source and enhances the desired illumination display effect.

A display panel 16 that covers almost the entire main surface side of the display substrate 11 is mounted in front of the front surface of the lamp module 13 . A system diagram showing the manufacturing process of various products in a factory or the like is drawn on the main surface of the display panel 16, and the lamp module 13 is arranged from a predetermined back side of the display panel 16 to the front side of the display panel 16. It has a structure that illuminates and displays the symbols, etc.

On the other hand, on the other side of the display substrate 11, a resistor is provided at a portion corresponding to the display unit 12.
A control unit including a diode (not shown) is installed. This control unit 17 has a structure in which a power supply voltage is supplied through a connector 18, whereby light emitting diodes, etc. in the lamp module 13 are activated, and the illumination display on the display panel 16 is controlled. It's summery.

Further, although FIG. 8 shows an example in which the display substrate cells 1 are connected by the joint member 5 on the other surface side, they are connected by the joint member 5 on the main surface side where the display unit 12 is attached. You can do it like this. Even in such a case, the display unit 12 can be attached to the connecting portion on the main surface side without any hindrance.

Therefore, according to this embodiment, it is possible to mount various units such as the display unit 12 or the control unit 17 on the entire main surface or other surface of the display substrate 11 formed in a connected state. Therefore, the degree of freedom in setting the illumination display is extremely high.

As described above, according to the display format explained above, although there is a limit to the pitch interval of the through holes 2 on the surface of the display substrate cell 1 in the bonded state, it is not as large as the display panel 30 explained in the related art. As a result, it is possible to provide a free-mount display panel with an extremely high degree of freedom in mounting the display unit 12 and the like.

FIG. 9 shows an example in which the display substrate 11 of this embodiment is applied to a mosaic display panel, and the lamp module 13, separate plate 14, and filter 15 that constitute the display unit 20 mounted on the display substrate 11 are as follows. Although it is similar to that shown in FIG. 7 above, it also includes a cap 21 that covers the front and side surfaces of the lamp module 13. This cap 21 is made of transparent synthetic resin, and its front surface is configured as a rectangular display surface. A two-dimensional or three-dimensional pattern is formed on the display surface by means such as printing or engraving, and the structure is such that the pattern, etc. on the cap 21 is illuminated and displayed by the light emitted from the lamp module 13. . Further, the cap 21 has a claw portion 22 extending from the side surface thereof, and the claw portion 22 is inserted into the through hole 2 from the main surface side of the display substrate 11, and the claw portion 22 is inserted into the through hole 2 from the main surface side of the display substrate 11. The display unit 20 is integrally held on the main surface of the display substrate 11 by being engaged with the peripheral edge of the opening of the through hole 2 . Here, the external dimensions of the cap 21, that is, the vertical and horizontal dimensions X and Y of the rectangular display surface are each an integral multiple of the pitch interval P of the through holes 2 formed in the display substrate 11 (X, Y=P×n). It is configured so that By standardizing the vertical and horizontal dimensions of the display surface of the cap 21 constituting the outermost peripheral surface of the display unit 20 in this way, the display unit 20 can be disposed on the display substrate 11 without any gaps. Note that a control unit 17 similar to that shown in FIG. 8 is mounted on the other side of the display substrate 11 corresponding to the display unit 20. A joint member 5 connects the constituent display substrate cells 1 to each other.
Since the through holes 2 are configured to maintain the connected state, the control unit 17 can be installed without any trouble even in the connected portion of the display substrate cells 1, and the display substrates 11 formed in the connected state can be mounted. A mosaic display is possible over almost the entire main surface.
