Has been done. However, the method of connecting the plurality of display modules 1 is not limited to this.

[Action and effect]
As described above, in the display module 1 of the present embodiment and the display device 100 provided with the display module 1, since the plurality of display panels 20 are provided on one common wiring board 10 without overlapping each other, the display panels 20 are provided with each other. There is no step at the joint. Therefore, the visibility of the displayed image is excellent. Further, the entire display module 1 and the entire display device 100 can be made thinner and have excellent flexibility. Therefore, according to the display module 1 and the display device 100, it is possible to have both excellent display performance and excellent handleability even when the size is increased.

Further, in the display module 1, a plurality of display panels 20 are individually arranged on one common wiring board 10. That is, the plurality of display panels 20 are not directly connected to each other. Therefore, even when thermal expansion occurs in each display panel 20 due to heat generation during driving, it is possible to reduce the influence of the thermal expansion on the distortion of the entire display module 1.

Further, in the present embodiment, the plurality of display panels 20 are arranged so as to be separated from each other along the surface 10S1. Therefore, as compared with the case where a plurality of display panels 20 are arranged so as to be in contact with each other, the display panels 20 give each other even when thermal expansion occurs due to heat generation during driving or the like. Distortion can be further reduced.

Further, in the present embodiment, as shown in FIG. 3, among the plurality of display elements 23, the outermost

edge display elements

23A and 23B arranged closest to the edge 20AT and 20BT of the display panel 20 are the ends. It is arranged at the position of LA, LB at a distance of less than half of the arrangement pitch P from the edges 20AT and 20BT. Therefore, the distance between the outermost edge display element 23A and the outermost edge display element 23B that are adjacent to each other across the gap GP can be made closer to the arrangement pitch P. In particular, when the conditional expression (1) is satisfied, the distance between the outermost edge display element 23A and the outermost edge display element 23B adjacent to each other across the gap GP is equal to or less than the arrangement pitch P of the display element 23. Therefore, when displaying an image, it becomes difficult to visually recognize the gap GP, which is a gap between the display panels 20, even if the luminance is not corrected.

Further, in the present embodiment, since the heat radiating film 30 is provided so as to face the back surface 10S2 of the common wiring board 10, the heat generated during driving on the display panel 20 is quickly dissipated. Further, since the heat dissipation wiring 31 is provided from the plurality of display elements 23 to the heat dissipation film 30, the heat generated by the display panel 20 is more quickly conducted to the heat dissipation film 30 and discharged to the outside. Can be done.

Further, in the present embodiment, in the display panel 20, a pad 24 is provided on the back surface 21S2 of the support 21, and a plurality of wirings 22 and the pad 24 are connected by a via 25 penetrating the support 21. Therefore, the length of the conduction path from the wiring 22 of the display panel 20 to the wiring 11 of the common wiring board 10 can be shortened, and the wiring resistance can be reduced.

FIG. 5 is a cross-sectional view showing the overall configuration of the display module 101 as a first modification of the first embodiment. As shown in FIG. 5, the display module 101 further has an elastic insulating layer 41 having an elastic modulus smaller than that of the base material 21A of the support 21, for example, between the wiring 22 and the common wiring board 10. .. The elastic insulating layer 41 is made of, for example, an epoxy resin. Further, the via 25 and the pad 24 are provided at substantially the center of each display panel 20. In the display module 101, the base material 21A exists only in the region surrounding the via 25 in the support 21, and the elastic insulating layer 41 is provided between the insulating layer 21B and the wiring 11 in the other regions. I have to. The configuration of the display module 101 as a modification of the present embodiment is substantially the same as the configuration of the display module 1 of the first embodiment, except for these points.

In this modification, since the elastic insulating layer 41 is further provided, the stress applied to each display panel 20 when the entire display module 101 is curved can be relaxed, and the mechanical load is reduced. be able to. Further, since the via 25 and the pad 24 are provided at substantially the center of each display panel 20, the variation in stress applied to each display panel 20 is reduced, and the via is locally applied to a part of each display panel 20. It is possible to prevent a large amount of stress from being applied. Therefore, the adverse effect on the display performance can be reduced.

<< 1.3 Second variant >>
FIG. 6 is a cross-sectional view showing the overall configuration of the display module 102 as a second modification of the first embodiment. As shown in FIG. 6, the display module 102 is provided with a display panel 120 (120A1, 120B1, 120C1) instead of the display panel 20 (20A1, 20B1, 20C1). Except for that point, the configuration of the display module 102 is substantially the same as the configuration of the display module 1 of the first embodiment.

As shown in FIG. 6, in the display module 102 of the present modification, each display panel 120 has a folded portion 27 that is folded and overlapped so that the surface 21S faces outward in each end region. ing. That is, the insulating layer 21B and the wiring 22 provided on the front surface 21AS1 of the base material 21A are folded back so as to surround the end surface of the base material 21A and extend to the back surface 21AS2 of the base material 21A. The wiring 22 can be connected to the wiring 11 provided on the common wiring board 10 via the pad 28 provided in the portion sandwiched between the back surface 21AS 2 of the base material 21A and the common wiring board 10. ..

Also in the display module 102 of this modification, since the plurality of display panels 120 are provided on one common wiring board 10 without overlapping each other, no step is generated at the joint portion between the display panels 120. Therefore, the visibility of the displayed image is excellent. In addition, the display module 102 as a whole can be made thinner and has excellent flexibility. Therefore, according to the display module 102 and the display device 100 including a plurality of the display modules 102, it is possible to have both excellent display performance and excellent handleability even when the size is increased.

<2. Second Embodiment>
<< 2.1 Basic form >>
FIG. 7 is a cross-sectional view showing an overall configuration example of the display module 2 as the second embodiment of the present disclosure. In the display module 1 and the like of the first embodiment, the plurality of display panels 20 are arranged on the common wiring board 10 without overlapping each other. On the other hand, in the display module 2 of the present embodiment, as shown in FIG. 7, adjacent display panels 50 are connected to each other with their ends overlapping each other. In FIG. 7, for convenience of explanation, the three display panels 50 arranged in the X-axis direction are designated by the

reference numerals

50A, 50B, and 50C in order from the left. However, the

display panels

50A, 50B, and 50C have substantially the same configuration. Further, the support 61, the base material 61A, the insulating layer 61B, the wiring 62, the display element 63, the pad 64 and the via 65 shown in FIG. 7 are the support 21 and the base material 21A in the first embodiment, respectively. It corresponds to the insulating layer 21B, the wiring 22, the display element 23, the pad 24, and the via 25, and has substantially the same configuration. However, in each display panel 50, the insulating layer 61B protrudes from the base material 61A in the −X direction to form the first connecting portion 51. Further, the base material 61A protrudes from the insulating layer 61B in the + X direction to form the second connecting portion 52. The wiring 62 is provided on the front surface 61BS1 of the insulating layer 61B, the pad 64 is provided on the back surface 61BS2 of the insulating layer 61B exposed at the first connection portion 51, and the via 65 connects the wiring 62 and the pad 64. It penetrates the insulating layer 61B so as to be connected. Further, in the second connecting portion 52, a pad 67 is provided on the surface 61AS1 of the base material 61A, and the wiring 62 and the pad 67 are connected by a via 66 penetrating the insulating layer 61B.

In the display module 2, as shown in FIG. 7, each

display panel

50A, 50B, 50C has a first connection portion 51 and a second connection terminal on which a pad 64 as a first connection terminal is formed, respectively. Includes a second connection 52 on which the pad 67 is formed. In the display module 2, the first connecting portion 51 and the second connecting portion 52 are connected to form a connecting portion 53 so that the pad 64 and the pad 67 are overlapped and electrically connected in the Z-axis direction. There is. Here, the thickness T51 of the first connection portion 51 and the thickness T52 of the second connection portion 52 are the maximum thickness T50 of the portion of the display panel 50 other than the first connection portion 51 and the second connection portion 52. It is desirable to be thinner than. This is because the thickness T53 of the connecting portion 53 between the first connecting portion 51 and the second connecting portion 52 can be reduced in the display module 2. Further, it is desirable that the thickness T51 of the first connecting portion 51 and the thickness T52 of the second connecting portion 52 be each less than half the thickness of the maximum thickness T50. This is because, in the display module 2, the thickness T53 of the connecting portion 53 between the first connecting portion 51 and the second connecting portion 52 is equal to or less than the maximum thickness T51. In particular, if the total of the thickness T51 of the first connecting portion 51 and the thickness T52 of the second connecting portion 52 matches the maximum thickness T51, the step in the display module 2 is eliminated, which is even more so. preferable.

FIG. 8 is an enlarged cross-sectional view showing the vicinity of the connecting portion 53 between the display panels 50 in the display module 2 in an enlarged manner. As shown in FIG. 8, for example, a part of the display element 63 of the display panel 50B is positioned so as to overlap both the pad 67 of the display panel 50A and the pad 64 of the display panel 50B in the Z-axis direction. That is, a part of the display element 63 of the display panel 50B is located at a position corresponding to the connecting portion 53 between the display panel 50A and the display panel 50B. Although not shown in FIG. 8, similarly, a part of the display element 63 of the display panel 50C is located at a position corresponding to the connecting portion 53 between the display panel 50B and the display panel 50C. Here, it is preferable that at least one of the pad 64 and the pad 67 contains the anisotropic conductive film ACF. With such a configuration, for example, when the display panels 50 are connected to each other in the manufacturing process, the load applied to the connecting portion 53 is effectively applied to the joint surface between the pad 64 and the pad 67, which is more robust. The connection will be made.

As described above, in the display module 2 of the present embodiment, the plurality of display panels 50 are directly connected by the connection between the first connection unit 51 and the second connection unit 52. Compared with the display module 1 of the embodiment, the configuration can be simplified. Further, since the thickness T51 of the first connection portion 51 and the thickness T52 of the second connection portion 52 of each display panel 50 are made thinner than the maximum thickness T50 of the display panel 50, the display module 2 It is possible to reduce the thickness as a whole.

<< 2.2 First Modification >>
FIG. 9 is an enlarged sectional view showing an enlarged connection portion 53 of the display module 201 as a first modification of the second embodiment. As shown in FIG. 9, in the display module 201, all the display elements 63 are provided at positions that do not overlap in the Z-axis direction with the connecting portion 53 to which the pad 64 and the pad 67 are joined. Except for this point, the configuration of the display module 201 is substantially the same as the configuration of the display module 2 as the second embodiment.

In this modification, due to such a configuration, for example, when the display panels 50 are connected to each other in the manufacturing process, the load applied to the connecting portion 53 is less likely to be applied to the display element 63. Therefore, it is possible to prevent the display element 63 from being damaged or the display element 63 from falling off from the display panel 50.

<3. Third Embodiment>

In the display module 1 and the like according to the first embodiment, a plurality of display panels 20 including a plurality of display elements 23 are arranged on one common wiring board 10. On the other hand, in the sensor module 3 of the present embodiment, a plurality of sensor panels 70 are provided on one common wiring board 10 instead of the plurality of display panels 20. Except for this point, the configuration of the sensor module 3 is substantially the same as the configuration of the display module 1.

As shown in FIG. 11, each sensor panel 70 of the sensor module 3 is provided with a plurality of sensor elements 73 instead of the display element 23. Except for that point, the configuration of the sensor panel 70 is substantially the same as the configuration of the display panel 20. The sensor element 73 is various sensors such as a pressure sensor, a piezoelectric sensor, a temperature sensor, a vibration sensor, a strain sensor, an optical sensor, a magnetic sensor, or a touch sensor. The sensor element 73 may further include a drive element including a control circuit such as an IC for driving the sensor.

Since the sensor module 3 is excellent in flexibility, it can be installed along the surface shape of a structure having a curved three-dimensional shape such as the robot hand shown in FIG. Further, it can be cut into an arbitrary shape according to the shape of the place to be installed and installed at a required portion. Further, even if a part of the sensor panel 70 is damaged by use, only the damaged sensor panel 70 can be replaced. Further, since the sensor module 3 is thin and has excellent flexibility, it can be avoided that the sensor module 3 interferes with the operation of the robot hand even when it is provided on the robot hand as shown in FIG. Further, by providing the plurality of sensor panels 70 provided in the sensor module 3 on the common wiring board 10 without overlapping each other as shown in FIG. 11, a step is generated along the surface of the structure. It can be avoided. Therefore, for example, when the sensor element 73 is a pressure sensor, it is possible to reduce variations and errors in the detected characteristic values.
