Description

  The present invention relates to an information display device capable of variably displaying information.

  Conventionally, as a display device for displaying information, a CRT display, a liquid crystal display, a plasma display, and the like are used. These are used in a television receiver to display a television image transmitted from a television station or a personal computer. It is possible to display information stored in a personal computer or information distributed via the Internet. Each of these display devices has advantages and disadvantages. For example, a CRT display has a wide viewing angle but a large depth size, and a liquid crystal display has a thin depth size but a narrow viewing angle, and a plasma display. Has a large viewing angle and a small depth size, but consumes a lot of power.

  In recent years, in addition to the display devices described above, thin information display devices that display digital information on a thin display medium such as paper have begun to spread. Thin information display devices are easy to carry because they are thin like paper, consume less power, have a wide viewing angle, and can rewrite information displayed by the voltage applied to the electrodes. Since the display contents can be retained even when the power is turned off, further spread in the future is expected.

  As a thin information display device as described above, by sandwiching an information display layer whose state changes according to an applied potential difference between two opposing electrodes, and applying a voltage to the two electrodes, What makes the color according to the potential difference visible is used. Therefore, it is considered that a predetermined pattern is printed on the information display layer, thereby making the pattern visible or difficult to see depending on the color of the information display layer (see, for example, Patent Document 1). .)

JP 2009-86029 A

  However, as described above, by printing a predetermined pattern on the information display layer, it is possible to visually recognize the pattern by the color of the information display layer, or it is difficult to view the pattern. Is only visible or difficult to see, and there is a problem that versatility is poor.

  The present invention has been made in view of the problems of the conventional techniques as described above, and provides an information display device capable of providing versatility when displaying information by visually recognizing colors. The purpose is to do.

In order to achieve the above object, the present invention provides:
An information display member having a display area for switching any one of the first and second colors;
An overlapping member formed by combining a see-through portion and a non-see-through portion made of the second color in a shape according to notification information;
A plurality of overlapping members formed by combining the fluoroscopic part and the non-transparent part in a shape corresponding to different notification information are selectively superimposed on the display area.

  In the present invention configured as described above, when the first color is displayed in the display area in a state where the overlapping member is superimposed on the display area provided in the information display member, the overlapping member is seen through. The first color of the display area is visually recognized through the part, and the notification information is displayed from the first color and the second color of the non-perspective part of the overlapping member. Further, when the second color is displayed in the display area in a state where the overlapping member is superimposed on the display area provided in the information display member, the second of the display area is displayed via the fluoroscopic part of the overlapping member. Although the color is visually recognized, the non-fluoroscopic part for displaying the notification information in combination with the fluoroscopic part is composed of the second color, so that the notification information by the combination of the fluoroscopic part and the non-fluoroscopic part is difficult to visually recognize. In this way, the color displayed in the display area in a state where the overlapping member is superimposed on the display area provided in the information display member is switched to one of the first and second colors. The notification information by the member can be displayed or not displayed. And on the display area, a plurality of overlapping members formed by combining a fluoroscopic part and a non-fluoroscopic part in a shape corresponding to different notification information are selectively overlapped, so that according to desired notification information By superimposing the overlapping member on the display area, desired notification information can be displayed or not displayed, and versatility can be provided.

  As described above, in the present invention, the information display member having a display area that displays one of the first and second colors in a switchable manner, the fluoroscopic portion and the first color in a shape corresponding to the notification information A plurality of overlapping members formed by combining the fluoroscopic portion and the non-transparent portion in a shape corresponding to different notification information on the display area. Is selectively overlapped, so that the color displayed in the display area is either the first color or the second color in a state where the overlapping member corresponding to the desired notification information is overlapped on the display area. By switching to, desired notification information can be displayed or not displayed, and versatility can be provided.

FIG.

  As shown in FIG. 1A, the present embodiment is an information display board 1 in which an overlapping label 10 that is an overlapping member is detachably attached to an information display sheet 20 that is an information display member.

  As shown in FIGS. 1B and 1C, the overlay label 10 is provided with a mask printing 15 on one surface of a transparent film 13 made of PET or the like, and is peeled off after being attached to the other surface. The transparent adhesive 14 that can be re-adhered is applied and configured. The mask printing 15 is applied using black ink as the second color in a shape corresponding to information to be notified using the information display board 1. In this embodiment, “◯” and “×” are displayed. As the notification information, the mask printing 15 is applied in a shape corresponding to the “o” and “x”, so that the fluoroscopic part 11a and the mask printing which are not subjected to the mask printing 15 are provided in the area where “o” is notified. 15 is provided, and a transparent portion 11b that is not subjected to mask printing 15 and a non-transparent portion 12b that is provided with mask printing 15 are provided in a region that notifies “x”. ing.

  As shown in FIGS. 1D to 1F, the information display sheet 20 has display electrodes 23a and 23b and conductor portions 25a and 25b formed on one surface, and an IC chip 24 and a CPU 26 connected thereto. , The information display layer 32 laminated on the surface of the base substrate 31 on which the display electrodes 23a and 23b and the conductor portions 25a and 25b are formed, and the base substrate 31 of the information display layer 32 A transparent conductive film substrate 35 laminated on a part of the surface opposite to the display electrodes 23a and 23b on the opposite surface, and the base substrate 31 of the information display layer 32 and the transparent conductive film substrate 35. Is composed of a mask layer 36 laminated on the entire surface of the opposite surface of the region not facing the display electrodes 23a, 23b. The regions facing the display electrodes 23a and 23b are display regions 21a and 21b.

  The base substrate 31 is made of, for example, PET, and the display electrodes 23a and 23b and the conductor portions are formed on the surface facing the information display layer 32 by screen printing using, for example, a conductive paste such as silver paste or carbon paste or conductive ink. 25a and 25b are formed. Each of the conductor portions 25a and 25b has an isosceles triangle shape, and is formed on the base substrate 31 so that the vertices of the isosceles triangle face each other through a gap. The IC chip 24 is mounted so as to be connected.

  The transparent conductive film substrate 35 is configured by forming a transparent electrode (for example, ITO) 33 on one surface of a transparent substrate 34 made of glass, a transparent film or the like, and the display electrodes 23a and 23b and the transparent electrode 33 are formed. The information display layer 32 is sandwiched between the display electrodes 23 a and 23 b and the transparent electrode 33.

  The information display layer 32 displays information according to the potential difference between the display electrodes 23a and 23b and the transparent electrode 33, and applies a predetermined voltage to the transparent electrode 33 to the display electrodes 23a and 23b. By selectively applying different voltages, the state of the region of the information display layer 32 facing the display electrodes 23a, 23b changes, and the color of the display regions 21a, 21b becomes different from each other due to the change in this state. This color difference is visually recognized from the transparent conductive film substrate 35 side. Examples of the information display layer 32 include an electrophoretic type, an electronic powder type, and an electrochromic type. A microcapsule type electrophoretic type is most preferable.

  When the overlapping label 10 and the information display sheet 20 configured as described above are attached as shown in FIG. 1A, an area composed of the see-through portion 11a and the non-see-through portion 12a of the overlap label 10. And the display area 21a of the information display sheet 20, and the area composed of the see-through part 11b and the non-permeate part 12b of the overlapping label 10 and the display area 21b of the information display sheet 20 face each other. As a result, the display areas 21 a and 21 b can be visually recognized through the see-through portions 11 a and 11 b of the overlapping label 10.

  Below, the utilization method of the information display board 1 comprised as mentioned above is demonstrated.

  FIG. 2 is a diagram illustrating an example of a method of using the information display board 1 illustrated in FIG.

  In the information display board 1 shown in FIG. 1, when an overlapped label 10 is stuck on the information display sheet 20, for example, when an IC tag attached to the product and storing the inspection result of the product is close to the information display board 1. The inspection result stored in the IC tag is read by the antenna composed of the conductor portions 25a and 25b and the IC chip 24, and a voltage is applied to the display electrodes 23a and 23b according to the read inspection result under the control of the CPU 26. Is done. When the inspection result is a non-defective product, for example, a positive voltage is applied to the display electrode 23a and a negative voltage is applied to the display electrode 23b. Then, in a region facing the display electrode 23a to which a positive voltage is applied, a potential difference that causes the transparent electrode 33 to be negative with respect to the display electrode 23a is generated, and thereby the first color is displayed in the display region 21a. In a region facing the display electrode 23b to which white is displayed and a negative voltage is applied, a potential difference that is positive on the transparent electrode 33 side occurs with respect to the display electrode 23b. Black, which is the second color, is displayed.

  Then, since the display areas 21a and 21b of the information display sheet 20 are visible through the fluoroscopic parts 11a and 11b, in the area facing the display area 21a as shown in FIG. The white color can be visually recognized through 11a, and “◯” is visually recognized by the white color and the black color of the non-transparent portion 12a. Further, in the area facing the display area 21b, black can be visually recognized through the fluoroscopic part 11b, and this black overlaps with the black of the non-transparent part 12b, so that “x” becomes difficult to visually recognize.

  When the inspection result is a defective product, for example, a negative voltage is applied to the display electrode 23a and a positive voltage is applied to the display electrode 23b. Then, in a region facing the display electrode 23a to which a negative voltage is applied, a potential difference that causes the transparent electrode 33 to be positive with respect to the display electrode 23a is generated, whereby black is displayed in the display region 21a. In a region facing the display electrode 23b to which a positive voltage is applied, a potential difference that causes the transparent electrode 33 to be negative with respect to the display electrode 23b is generated, whereby white is displayed in the display region 21b.

  Then, since the display areas 21a and 21b of the information display sheet 20 are visible through the fluoroscopic parts 11a and 11b, in the area facing the display area 21a as shown in FIG. The black color becomes visible through 11a, and this black color overlaps the black color of the non-transparent portion 12a, making it difficult to visually recognize “◯”. In the region facing the display region 21b, the white color is obtained via the transparent portion 11b. Can be visually recognized, and “x” is visually recognized by the white color and the black color of the non-transparent portion 12b.

  Thus, black or white in the display areas 21a and 21b of the information display sheet 20 depending on the combination of the see-through parts 11a and 11b and the non-see-through parts 12a and 12b of the overlapping label 10 attached to the information display sheet 20. The desired information is displayed by displaying. That is, on the display areas 21a and 21b of the information display sheet 20, labels in which the see-through parts 11a and 11b and the non-see-through parts 12a and 12b are combined in a shape corresponding to the notification information such as “◯” and “x”. As a result of selective overlapping, desired notification information such as “◯” or “×” is not displayed, and the combination of the see-through portion and the non-see-through portion of the overlap label 1 Information displayed or not displayed on one display area can be changed, and versatility can be provided.

  Further, by changing the overlapping label 110, it is possible to change the information display form in the area facing the display areas 21a and 21b.

  FIG. 3 is a diagram showing a form in which the information display board 1 shown in FIG. 1 uses a different label from that shown in FIG. 1 as the overlay label, and FIG. The figure which shows a form, (b) is a figure which shows the display state at the time of sticking the overlapping label 110 shown to (a) on the information display sheet 20 shown in FIG. 1, (c) is a figure which shows FIG. It is a figure which shows the display state at the time of sticking the overlapping label 110 shown to (a) on the shown information display sheet.

  The overlay label 110 shown in FIG. 3 is the same as that shown in FIG. 1 except that the first color is black, the second color is white, and the non-transparent portions 112a and 112b are printed with white ink. The only difference is that it is configured.

  When the overlapping label 110 shown in FIG. 3A is stuck on the information display sheet 20, for example, when an IC tag attached to the product and storing the inspection result of the product approaches, the same operation as described above Thus, when the inspection result is a defective product, for example, a positive voltage is applied to the display electrode 23a and a negative voltage is applied to the display electrode 23b. Then, in a region facing the display electrode 23a to which a positive voltage is applied, a potential difference that causes the transparent electrode 33 to be negative with respect to the display electrode 23a is generated, and thereby the first color is displayed in the display region 21a. In a region facing the display electrode 23b to which white is displayed and a negative voltage is applied, a potential difference that is positive on the transparent electrode 33 side occurs with respect to the display electrode 23b. Black, which is the second color, is displayed.

  Then, since the display areas 21a and 21b of the information display sheet 20 are visible through the fluoroscopic parts 111a and 111b, in the area facing the display area 21a as shown in FIG. The white color is visible through 111a, and this white color overlaps with the white color of the non-transparent part 112a, making it difficult to visually recognize the white circle. Can be visually recognized, and “x” is visually recognized by the black color and the white color of the non-transparent portion 112b.

  When the inspection result is a non-defective product, for example, a negative voltage is applied to the display electrode 23a and a positive voltage is applied to the display electrode 23b. Then, in a region facing the display electrode 23a to which a negative voltage is applied, a potential difference that causes the transparent electrode 33 to be positive with respect to the display electrode 23a is generated, whereby black is displayed in the display region 21a. In a region facing the display electrode 23b to which a positive voltage is applied, a potential difference that causes the transparent electrode 33 to be negative with respect to the display electrode 23b is generated, whereby white is displayed in the display region 21b.

  Then, since the display areas 21a and 21b of the information display sheet 20 are visible through the fluoroscopic parts 111a and 111b, in the area facing the display area 21a as shown in FIG. Black becomes visible through 111a, and “◯” is visually recognized by this black and the white color of the non-transparent portion 112a. Further, in the area facing the display area 21b, white is visible through the fluoroscopic part 111b, and this white color overlaps with the white color of the non-transparent part 112b, making it difficult to visually recognize “x”.

  Thus, by replacing the overlapping label 110 attached to the information display sheet 20, the information display form in the area facing the display areas 21a and 21b can be changed, and further versatility can be provided. it can.
