Description

  The present invention relates to an information medium in which a module is installed in a frame and a manufacturing method thereof.

  Conventionally, CRT displays, liquid crystal displays, plasma displays, and the like have been used as display media for displaying information. These are used for television receivers to display television images transmitted from television stations, personal computers, etc. It is possible to display information stored in a personal computer or information distributed via the Internet. Furthermore, in addition to the display medium as described above, a thin display medium that displays digital information on a thin information display layer such as paper is becoming widespread. Such a thin display medium is easy to carry because it is thin like paper, consumes less power, has a wide viewing angle, and can rewrite information displayed by the voltage applied to the electrodes. In addition, since the display contents can be retained even when the power is turned off, further spread is expected in the future.

  3A and 3B are diagrams illustrating an example of an information medium, in which FIG. 3A is a diagram viewed from the information display surface side, FIG. 3B is a cross-sectional view taken along the line AA ′ illustrated in FIG. FIG.

  In this example, as shown in FIG. 3, a display module 110 is arranged in a frame 120, and the frame 120 and the display module 110 are sandwiched from the front and back by a front surface base material 130a and a back surface base material 130b. The bonding resin 140 is filled between the frame 120 and the display module 110 and the front surface base material 130a and the back surface base material 130b, and between the frame 120 and the display module 110, respectively.

  In the information medium 101 configured as described above, since the surface base material 130a is made of a transparent material, information displayed on the display module 110 is displayed on the information display unit 102 with the background unit 103 as a background. It will be displayed and viewed.

  In this way, by providing the display module constituting the thin display medium in the frame and tagging it, the environmental resistance of the display medium can be improved (for example, see Patent Document 1).

JP 2012-73727 A

  As described above, when a module such as a display module is provided in the frame to form a tag, the frame needs to be equal to the thickness of the module or thicker than the module. Therefore, when the thickness of the module is increased, the thickness of the frame is increased accordingly.

  By the way, the dimensional accuracy of the frame is determined by the ratio to the thickness. For this reason, when the thickness of the frame is increased, the dimensional accuracy is deteriorated, resulting in variations in dimensions. In such a case, the function of the information medium may be adversely affected, for example, the module position may vary and the display area may be shifted if the module is a display module.

  The present invention has been made in view of the problems of the prior art as described above, and in the information medium tagged by installing the module in the frame, the thickness of the module is increased. An object of the present invention is to provide an information medium in which module misalignment is less likely to occur.

In order to achieve the above object, the present invention provides:
In an information medium comprising a frame, a module installed in the frame, and a pair of base materials sandwiching the frame and the module, the frame having a thickness corresponding to the module,
The frame is formed by laminating a plurality of outer frame members,
The adhesive resin is filled between the plurality of outer frame members, between the frame and the module and the base material, and between the frame and the module.

  In the present invention configured as described above, the frame in which the module is installed is configured by laminating a plurality of outer frame members and filling an adhesive resin between the plurality of outer frame members. Therefore, even when the thickness of the module is increased, a frame corresponding to the thickness of the module can be configured by stacking a thin outer frame member corresponding to the thickness of the module. In this case, since the dimensional accuracy of the frame corresponds to the thickness of the thin outer frame member, the dimensional accuracy of the frame does not deteriorate even when the thickness of the frame is increased.

A method for manufacturing the information medium,
Installing the plurality of outer frame members on one of the pair of substrates, and applying a molten adhesive resin to the inside of the frame on the one substrate;
Installing the module inside the frame;
Applying a molten adhesive resin on the module;
On the frame and the module, the other base material of the pair of base materials is overlapped, and the other base material is pressed against the one base material side, thereby the space between the plurality of outer frame members. Filling the adhesive resin between the frame and the module and the base material, and between the frame and the module.

  As described above, the adhesive resin in a molten state is applied onto the base material or the module, and the base material is pressurized to fill the adhesive resin between the frame and the module and the base material and between the frame and the module. Since the adhesive resin is filled between the plurality of outer frame members in the process, it is not necessary to join the plurality of outer frame members in advance.

  In the present invention, since the frame in which the module is installed is configured by laminating a plurality of outer frame members and filling the bonding resin between the plurality of outer frame members, the thickness of the module Even when the thickness of the frame increases, a frame corresponding to the thickness of the module can be configured by stacking the outer frame members having a small thickness corresponding to the thickness of the module. In the information medium that is tagged by being installed internally, even when the module is thick, the dimensional accuracy of the frame is not deteriorated, and the module is hardly displaced. In addition, since the outer frame member having a small thickness has flexibility, the frame bending resistance can be improved by forming a frame by stacking a plurality of the outer frame members. Furthermore, by forming a frame by laminating a plurality of outer frame members, even if a crack occurs in the frame, the crack does not easily reach the entire frame, and the frame is not easily damaged.

  Also, in the step of applying a molten adhesive resin on the base material or module, and pressurizing the base material to fill the adhesive resin between the frame and the module and the base material and between the frame and the module, respectively. Since the adhesive resin is filled between the plurality of outer frame members, it is not necessary to join the plurality of outer frame members in advance.

  Embodiments of the present invention will be described below with reference to the drawings.

  1A and 1B are diagrams showing an embodiment of an information medium of the present invention, where FIG. 1A is a view seen from the information display surface side, FIG. 1B is a cross-sectional view taken along line AA ′ shown in FIG. (C) is a figure which shows an internal structure.

  In this embodiment, as shown in FIG. 1, a display module 10 is provided in a frame 20, and the frame 20 and the display module 10 are a pair of base materials having the same shape, a front surface base material 30 a and a back surface base material 30 b. Between the front and back.

  The display module 10 has a rectangular shape, an information display layer (not shown) whose display color is changed by applying a voltage, and a control circuit unit (not shown) that applies a voltage to the information display layer. The information display surface of the information display layer is inscribed in the frame 20 in a direction facing the surface base material 30a.

  The frame 20 is configured by stacking three outer frame members 20a to 20c having the same shape. The outer frame members 20 a to 20 c have the same outer shape as the front surface base material 30 a and the back surface base material 30 b, and the inner shape thereof is a slightly smaller rectangular shape with respect to the outer shape of the display module 10. Thus, the display module 10 is inscribed in the frame 20 along the inner surface of the outer frame members 20a to 20c. Further, the outer frame members 20a to 20c are thinner than the display module 10, but the three outer frame members 20a to 20c are stacked, whereby the thickness of the frame 20 is changed to the display module 10. It is thicker than.

  The surface base material 30a consists of a transparent film etc., and makes the information displayed on the display module 10 visible from the outside.

  The back substrate 30b is made of a film or the like.

  The adhesive resin 40 is filled between the three outer frame members 20a to 20c, between the frame 20 and the display module 10, the front surface base material 30a and the back surface base material 30b, and between the frame 20 and the display module 10. Thus, the three outer frame members 20a to 20c, the frame 20, the display module 10, the front surface base material 30a and the back surface base material 30b, and the frame 20 and the display module 10 are bonded to each other.

  In the information medium 1 configured as described above, since the surface base material 30a is made of a transparent material, the information displayed on the display module 10 is displayed on the information display unit 2 with the background unit 3 as the background. Will be displayed and visually recognized.

  Below, the manufacturing method of the information medium 1 mentioned above is demonstrated.

  FIG. 2 is a diagram for explaining a method of manufacturing the information medium 1 shown in FIG.

  When the information medium 1 shown in FIG. 1 is manufactured, first, three outer frame members 20a to 20c are stacked and installed on one surface of the surface base material 30a, and one of the surface base materials 30a. The adhesive resin 40 in a molten state is applied to a region surrounded by the frame 20 formed by laminating the outer frame members 20a to 20c on the surface (FIG. 2A). At this time, it is preferable that the relative positions of the surface base material 30a and the outer frame members 20a to 20c are determined using abutment or positioning pins.

  Next, the display module 10 is installed in the frame 20 so that the information display surface thereof faces the surface base material 30a (FIG. 2B). At this time, since the inner shape of the outer frame members 20a to 20c is slightly smaller than the outer shape of the display module 10, the display module 10 is arranged so as to be along the inner surface of the outer frame members 20a to 20c. 20 will be inserted. Thereby, alignment of the display module 10 can be performed easily.

  Next, a molten adhesive resin 40 is applied on the display module 10 (FIG. 2C).

  Thereafter, the back substrate 30b is overlaid on the frame 20 and the display module 10, and the back substrate 30b is pressed toward the front substrate 30a. At this time, it is preferable that the relative positions of the back substrate 30b and the outer frame members 20a to 20c are determined by using abutment or positioning pins.

  Then, since the adhesive resin 40 is in a molten state, the adhesive resin 40 is pressed against the back substrate 30b and the display module 10 so that the surface substrate 30a and the back substrate 30b are interposed between the display module 10 and the display module 10. The display module 10 enters the area surrounded by the frame 20. In this way, by pressing the display module 10 and the back substrate 30b against the front substrate 30a and the display module 10 to which the molten adhesive resin 40 is applied, the front substrate 30a and the back substrate 30b are pressed. The display module 10 is bonded to the display substrate 10 without generating bubbles or the like between the front substrate 30a and the back substrate 30b and the display module 10, thereby making it possible to view information through the front substrate 30a. This is effective for avoiding the decrease.

  As the display module 10 enters the area surrounded by the frame 20, the molten adhesive resin 40 extends from the central portion of the display module 10 to the surroundings, and the display module 10, the front substrate 30a, and the back surface. The display module 10 is filled with the base material 30b, and the display module 10 is bonded to the front surface base material 30a and the back surface base material 30b by the adhesive resin 40 on the entire surface. Further, the bonding resin 40 is filled between the display module 10 and the frame 20, and the display module 10 and the frame 20 are bonded together by the bonding resin 40.

  The extended adhesive resin 40 is also filled between the frame 20 and the front surface base material 30a and the back surface base material 30b, and is also filled between the three outer frame members 20a to 20c. The front substrate 30a and the back substrate 30b are bonded together, and the three outer frame members 20a to 20c are bonded to each other, and the information medium 1 shown in FIG. 1 is completed (FIG. 2D).

  Since the information medium 1 manufactured as described above is tagged with the frame 20, the thickness of the frame 20 needs to be thicker than that of the display module 10, but the frame 20 includes a plurality of outer frame members. Since 20a to 20c are laminated and the adhesive resin 40 is filled between the plurality of outer frame members 20a to 20c, the thickness is small even when the thickness of the display module 10 is increased. By stacking the outer frame members 20 a to 20 c by the number corresponding to the thickness of the display module 10, the frame 20 thicker than the display module 10 can be configured. In that case, since the dimensional accuracy of the frame 20 corresponds to the thickness of the thin outer frame members 20a to 20c, the dimensional accuracy of the frame 20 is deteriorated even when the thickness of the frame 20 is increased. Nothing will happen. Thereby, even when the thickness of the display module 10 is increased, it is difficult to cause the positional displacement of the display module 10. Further, since the thin outer frame members 20a to 20c have flexibility, the frame 20 is formed by stacking a plurality of the outer frame members 20a to 20c, whereby the bending resistance of the frame 20 is improved. Can be improved. Further, by forming the frame 20 by laminating a plurality of outer frame members 20a to 20c, even if a crack occurs in a part of the frame 20, the crack is difficult to reach the entire frame 20, and the frame 20 Is less likely to break.

  Even when the thickness of the frame 20 does not need to be thicker than that of the display module 10 installed in the frame 20, the thickness of the frame 20 depends on the display module 10 in order to form a tag. Even in such a case, the outer frame members 20a to 20c having a small thickness may be stacked by the number corresponding to the thickness of the display module 10, and the dimensions of the frame 20 are increased even when the thickness of the frame 20 is increased. The accuracy will not deteriorate.

  Further, as described above, the adhesive resin 40 in a molten state is applied on the surface base material 30a and the display module 10, and the frame 20, the display module 10, the surface base material 30a, the back surface base material 30b, and the frame In order to fill the bonding resin 40 between the plurality of outer frame members 20a to 20c in the step of pressurizing the back substrate 30b to fill the bonding resin 40 between the display module 20 and the display module 10, respectively, There is no need to provide a step of previously joining the frame members 20a to 20c.

  In the above-described embodiment, the display module 10 having the information display function is described as an example of the module. However, the module of the present invention is not limited to this, and an antenna is formed on the base substrate. Various devices such as a device having an RFID function mounted with an IC chip that performs non-contact communication via the antenna can be applied.
