DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0013]
FIG. 1 shows a plan view of a paper-like nonvolatile information display medium (1) used in the returnable container of the present invention. This paper-like non-volatile information display medium (1) is stored in a non-contact IC card LSI (10) for transmitting / receiving information data to / from the reader / writer (2) and a non-contact IC card memory. The display drive LSI (20) to be displayed on the non-volatile information display unit (40) based on the stored information data, the power source unit (30) for driving, and the non-volatile information display unit (40). .
[0014]
This paper-like non-volatile information display medium (1) receives non-contact information data such as a delivery destination, a product name, a shipping date, a manufacturing date, a size, and a weight to be visually displayed from the reader / writer (2). It is stored in the memory of the contact IC card LSI (10) and can be displayed as shown in FIG. 2 by the display drive LSI (20).
[0015]
As shown in FIG. 3, the non-contact IC card LSI (10) includes a CPU (11), a memory (13) for storing programs and information data to be transmitted and received, a memory control means (12) for controlling the memory, and an antenna (15 ), A transmission / reception means (14) for transmitting / receiving information data to / from the reader / writer, and a display driver control means (16) for controlling the exchange of information data with the display driver.
[0016]
The non-volatile information display unit (40) is a display medium that can maintain and store this state with little power consumption if there is no next rewriting command once the information is displayed. It is what has been. As a display technology for this electronic paper, a twisting ball, an electric transfer method in which charged particles are contained in microcapsules and a particle is moved by applying a charge, an electrochromic method in which a color is changed by applying a charge, etc. .
[0017]
FIG. 4 shows an example of a cross-sectional configuration diagram of a paper-type non-volatile information recording unit of an electric transfer method in which charged particles are contained in microcapsules and a charge is applied to move the particles among these methods.
A conductive layer is formed on a plastic film having excellent dimensional stability such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), and polyimide on a flexible base material (41e) such as paper and plastic. Transparent plastics with excellent dimensional stability such as electrode film (41d) or SAS plate that also serves as a base material and conductive layer, image display layer (41c), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyimide A transparent electrode film (41b) on which an active matrix electrode, a segment electrode, and a simple matrix electrode (not shown) are formed and a surface protective layer (41a) for protecting the display portion are laminated on the film.
[0018]
An example of the microcapsule (110) used for the image display layer (41c) is shown in FIG.
Methacrylic acid resin, urea resin, gum arabic, etc. are used as the capsule shell (111). Inside, white particles (113) made of titanium oxide and black particles (114) made of carbon black are made of viscous oil such as silicone oil. It is dispersed and encapsulated with a high dispersion medium (112). White particles of titanium oxide are positively charged, while black particles of carbon black are negatively charged.
[0019]
For this reason, as shown in FIG. 6B, when an electric field is applied to the two electrode films (41b and 41d), the electrode film of 41b becomes a negative electrode and the electrode film of 41d becomes a positive electrode, it is positively charged. Since the white particles (113) are drawn to the electrode film side of 41b and the black particles (114) are drawn to the electrode film side of 41d, the portion looks white when observed from above the transparent electrode side of 41b.
[0020]
Conversely, when the electrode film 41b becomes a positive electrode and the electrode film 41d becomes a negative electrode, positively charged white particles (113) are drawn to the electrode film side of 41d and black particles (114) are electrodes of 41b. Since it is drawn to the film side, when observed from above the transparent electrode side of 11b, the portion looks black.
[0021]
The image display layer (41c) has a large number of such microcapsules (110). By controlling the electric field of each address electrode of the electrode film (41b), the image display layer (41c) is referred to as “A” in FIG. As characters are displayed in black, desired characters and figures can be displayed with white and black pixels.
[0022]
Since each particle is dispersed in a highly viscous dispersion medium (112), once the electric field is applied, the position of the particle does not change even when the power is turned off. It has non-volatility that does not disappear.
[0023]
In the above example, the microcapsule is a monochrome (black and white) display containing two types of black and white particles. However, the microcapsules can be displayed in color by containing particles of different colors or contain two or more types of particles. It is also possible to make it.
[0024]
The above microcapsules contain two types of black and white particles, but monochrome (black and white) display can also be realized by using one type of particles and coloring the dispersion medium black.
That is, as shown in FIG. 7, using microcapsules in which white particles of titanium oxide are positively charged and dispersed in a black dispersion medium (115), two electrode films (41b, 41d) are used. When an electric field is applied and the electrode film of 41b becomes a negative electrode and the electrode film of 41d becomes a positive electrode, positively charged white particles (113) are attracted to the electrode film side of 41b and are dispersed in black ( 115) is inevitably pushed down to the electrode film side of 41d, so that when viewed from above the transparent electrode side of 41b, the portion looks white.
[0025]
Conversely, when the electrode film 41b becomes a positive electrode and the electrode film 41d becomes a negative electrode, positively charged white particles (113) are drawn to the electrode film side of 41d and are colored black (115). Is inevitably pushed up to the electrode film side of 41b, and when observed from above the transparent electrode side of 41b, the portion looks black.
[0026]
The above example is an example of monochrome (monochrome) image display, but in the case of color image display, as shown in FIG. 8, R (red), G (green), and B (blue) divided into pixel units. ) Color filter (41f) is provided on the transparent electrode film (41b) side to which an electric field can be applied in pixel units.
That is, the observation light of the portion where the white particles are drawn to the 41b side is reflected by the white particles and passes through the color filter, so that the color of the color filter is observed.
In the example of FIG. 8, the R and G pixel portions of the color filter have white particles drawn toward the transparent electrode film side of 41b, so that R light and G light are observed, and the B pixel portion of the color filter is black particles. Is drawn to the transparent electrode film side of 41b, the observation light is absorbed and the B light is not observed.
In this way, color image display is possible by controlling the R, G, and B light observed in pixel units.
[0027]
This paper-like non-volatile information display section (40) is made of a flexible material, and the patterning of electrodes and the like can also be formed on a plastic film by a printing method or vapor deposition method. Thus, the above LSIs can be stacked.
[0028]
This paper-like non-volatile information display medium (1) has a non-volatility that once the electric field is applied, the position of the particles does not change even when the power is turned off, and the display image does not disappear even when the power is turned off. Therefore, it consumes very little power and can be displayed using a solar cell.
In addition, unlike liquid crystal display systems, glass is not used as the base material, and flexible plastics or thin SAS plates are used as the base material. It is a display medium suitable for.
[0029]
By attaching this paper-like non-volatile information display medium to the container, the contents of the container and the display of the contents can be matched, and the rationalization of the following physical distribution work can be expected.
[0030]
That is, a database that indicates contents and the like as shown in FIG. 9 is prepared. In addition, a container number or the like that can identify the container is stored in the EEPROM memory of the non-contact card LSI (10) provided in the nonvolatile information display medium (1).
[0031]
Therefore, as shown in FIG. 10, when the container number specifying this container is transmitted to the reader / writer (2), the reader / writer (2) searches the database for data corresponding to the container number, The corresponding data is transmitted to the nonvolatile information display medium (1).
The transmitted corresponding data is stored in the EEPROM memory of the non-contact card LSI (10). The corresponding data stored in the EEPROM is displayed on the nonvolatile information display section (40) by the display driver LSI (20).
By doing so, it becomes possible to match the display of the contents of the container with the contents.
[0032]
If you want to use this container repeatedly, you can create an updated database and rewrite it with similar operations.
[0033]
Although this paper-like non-volatile information display medium (1) can be directly attached to a container, a transparent substrate has a protective layer function by creating a pocket with a transparent substrate and storing it in this pocket. Is a preferred form.
[0034]
【The invention's effect】
As described above, by using a paper-like non-volatile display medium for a returnable container , the container can be specified by radio waves. The restrictions such as obstacles are relaxed.
In addition, since the contents of the contents cannot be determined only by using a bar code or the like, it is necessary to write them on a paper label or the like. However, in the present invention, the container identification and the contents are notated as a reader / writer. Since the data is displayed based on the data transmitted and received in step (b), the notation of the container and the contents matches. Further, it is not necessary to manually attach a paper label or the like, and troubles due to affixing are eliminated.
[0035]
In addition, since the display medium of the present invention is manufactured mainly using a film base, the risk of breakage due to impact is reduced as in a liquid crystal display medium, and the display medium is optimal for logistics. Further, since it is a non-volatile display medium, it has a feature of low power consumption.
