Description
[ technical field ] A method for producing a semiconductor device
The invention relates to an anti-counterfeiting modification device comprising a polarizing substance and an application method thereof.
[ background of the invention ]
In order to prevent the forgery and alteration of commodities requiring the authenticity of high-grade commodities or articles with internal components, various techniques have been introduced. Conventionally, technologies such as fine patterns, braille characters, holograms, and RFID have been mainly used to prevent forgery or alteration of a product, but such technologies have had problems in that it is difficult for a general user to identify whether a product is forged or altered or in that it is expensive to manufacture an anti-counterfeit means.
A QR code is a two-dimensional barcode in the form of a matrix displaying information in a black and white grid pattern. The QR code has an advantage of storing data of a larger size than a general barcode which stores digital or text information in one direction, and thus is widely used in many fields.
In general, a QR code is obtained by capturing an image with a camera mounted on a smartphone or the like or a device provided with a separate reader, and then reading stored data. That is, any user having a means to read the standard QR code can view the data within the QR code.
The present invention, such as a forgery-preventing altered printed matter including an information transmission layer on which a forgery-preventing altered image is printed on a substrate, is known from technical documents of forgery-preventing altered devices using a QR code, and mainly uses optically variable inks (OVPs), heat-sensitive inks, UV inks, fluorescent inks, holograms, and the like.
The conventional anti-counterfeiting modified printed matter has the advantage that the printed matter is difficult to be subjected to false modification, but also has the defect of high manufacturing cost of the printed matter, so that the problems of difficulty in batch production and high product unit price are caused.

Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings in which embodiments of the invention are shown, but the described embodiments are only a part and not all of the embodiments of the invention. Based on the embodiments of the present invention, those skilled in the art may still modify the technical solutions described in the foregoing embodiments, or may equivalently replace some of the technical features in the foregoing embodiments; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Various embodiments of the anti-counterfeiting changing device (100) comprising the polarizing material of the invention are described below with reference to fig. 1 to 4.
In the embodiments described below with reference to fig. 1 to 4, an extension film layer (not shown) and a base material layer (not shown) may be optionally provided, the extension film layer being formed of a Bi-Axially oriented PP film (not shown) having improved optical characteristics and improved transparency.
The oriented polypropylene film has improved optical properties and transparency, and has improved visibility for making colors expressed by refraction of polarized light more glitter.
First, according to fig. 1, the forgery prevention alteration device (100) including a polarizing substance according to an embodiment of the present invention further includes a polarizing layer (160) provided with a polarizing film or an ink containing a polarizing substance or with a polarizing film.
The polarizing layer (160) is a linear polarizing layer, a circular polarizing layer, an elliptical polarizing layer, or the like, and may be selectively provided in any form as required as long as it can transmit incident light by switching the polarization form.
Of course, the identification pattern can be arranged by using one of the circular polarization layers, namely, the polarization film containing cholesteric liquid crystal or the ink, and the identification pattern can be latent image on the polarization layer (160) by the combination of the polarization layers or the combination of the polarization layers and the common ink layer.
Further, one surface of the polarizing layer (160) may further include a display layer (130) on which the identification pattern is latent-imaged, and the display layer (130) may include the first display layer (131) and the second display layer (132).
As above, the first display layer (131) and the second display layer (132) may include: the display device includes an embodiment in which only one of the display layers is printed with an ink containing cholesteric liquid crystal, and the remaining display layers are printed with a normal ink, and a plurality of embodiments in which the first display layer (131) and the second display layer (132) are both printed with an ink containing cholesteric liquid crystal.
Complementary fluorescent dye can be added to the cholesteric liquid crystal of the ink containing the cholesteric liquid crystal, and the color of the added complementary fluorescent dye and the dye contained in the polarizing layer (160) or the design printing layer (not shown) of the base layer (not shown) form a complementary color contrast relation.
In this case, a pigment that has a complementary color contrast relationship with the complementary color fluorescent dye contained in the cholesteric liquid crystal may be added to the design printing layer (120).
The complementary color contrast relationship is a combination of colors that are generally located on opposite sides of each other in a hue ring, and when vermillion and green, yellow and blue, and the like are viewed side by side, the colors appear more intense and vivid due to their mutual influence.
According to the present embodiment, in a state where non-polarized light is irradiated from top to bottom, when viewed from the upper side downward, a recognition pattern (first recognition pattern) can be displayed by the display layer (130) and the polarizing layer (160).
When the display layer (130) is illuminated with light from the lower side to the upper side, the other identification pattern (second identification pattern) is seen by the light filtered by the polarizing layer (190) in the upward view, and the other identification pattern (third identification pattern) is seen in the upward view.
That is, the security of the forgery prevention device (100) is improved to the maximum extent by making the identification pattern viewed differently depending on the irradiation direction of light and the line-of-sight direction.
Then, another embodiment of the anti-counterfeiting texturing device (100) comprising a polarizing substance comprising a polarizing layer is described with reference to fig. 2.
The anti-counterfeiting changing device (100) comprising the polarizing substance comprises the polarizing layer (160), a display layer (130), a phase difference film layer (17) with an engraved pattern (170a) formed on the upper side, and a coating layer (180) covering the phase difference film layer (170).
First, the retardation film is an optically anisotropic film, and exhibits functions such as optical compensation, view angle enlargement, and color compensation depending on the purpose.
In this embodiment, the retardation film widens the optical element having birefringence, converts linearly polarized light that is slightly obliquely incident upon the retardation film by rotating the retardation film into a polarized state that is directly orthogonal to the analyzer transmission axis, and allows the latent images of the display layer (130) and the polarizing layer (160) to be clearly seen even if the polarized light is obliquely incident upon the coating layer.
According to the present embodiment, the latent image recognition power of the display layer (130) and the polarizing layer (160) is improved by the phase difference film (170), and a recognition pattern partially deformed by the intaglio pattern (170a) is exhibited.
Still another embodiment of a tamper-proof device (100) comprising a polarizing substance comprising a polarizing layer is then described with reference to fig. 3.
The anti-counterfeiting changing device (100) comprising the polarizing substance according to one embodiment of the invention can comprise the polarizing layer (160) and the display layer (130) containing the phase difference ink.
Specifically, the display layer (130) may include: a first display layer (131) provided with a normal ink or an ink containing cholesteric liquid crystal, and a second display layer (132') provided with a phase difference ink in which phase difference film powder is mixed in the normal ink.
The common ink and the phase difference film powder of the second display layer may be 100: mixing at a ratio of 1 to 30.
According to the present embodiment, when light is irradiated from the bottom to the top, the light emerging in the alignment direction on the first display layer (131) passes through the second display layer (132') and is converted into a polarization state orthogonal to the transmission axis, thereby being irradiated to the top side more brightly.
Then, another embodiment of the anti-counterfeiting altering device (100) comprising a polarizing substance is described with reference to fig. 4.
According to the embodiment, liquid crystal inks (K, T) having different alignment structures from each other are applied to the base layer (110), that is, one liquid crystal ink (K) is used as a cholesteric liquid crystal ink aligned in a helical direction, and the remaining liquid crystal inks (T) are arranged as cholesteric liquid crystal inks aligned in a reverse helical direction.
And not only spiral or inverse spiral, but also liquid crystal inks having different specific pattern orientations.
Next, fig. 5 to 8 show an embodiment of a forgery prevention alteration device (100) including a polarizing substance according to the present invention, and an embodiment of a forgery prevention alteration identifying method using the same.
First, according to fig. 5 and 7, the anti-counterfeiting changing device (100) including a polarizing substance according to an embodiment of the present invention may include a QR code (10) and an identification pattern (20).
According to fig. 6, after the QR code (10) is first verified by the mobile device (50) having a screen, the second determination as to whether or not the pseudo-alteration is present can be visually recognized and determined by using a pseudo-alteration confirmation interface (40) induced by a polarizing film (fig. 5) or a mobile device application (30) having a screen, which will be described later.
The pseudo alteration confirmation interface (40) may be irradiated with polarized light of a specific pattern, and the irradiated polarized light reaches the pseudo alteration confirmation device (100) including a polarizing material, and a second discrimination process using the polarized light is performed.
The false alteration confirmation interface (40) may use gray, ivory, yellow, blue or light green in addition to white, but may use a white background to most clearly recognize the recognition pattern (20).
The most preferred single color is white, which is an important factor in the present invention. Since polarized light is irradiated to the identification pattern with a white interface, the sharpness of the identification pattern is significantly improved compared to when polarized light is irradiated with other color interfaces.
The pseudo alteration confirmation interface (40) is such that 70% or more of the area of the interface may be composed of a single color background, and polarized light having a specific vibration direction may be irradiated. Further, the present invention can easily perform the second discrimination process without other polarizing films.
The method for discriminating the false alteration of the forgery prevention alteration device (100) including a polarizing substance by the mobile device (50) having the screen is described in detail with reference to fig. 8.
Step (a) first confirming the pseudo-alteration step:
the step (a) is a process of recognizing the QR code (10) by using a camera mounted on a mobile device (50) having a screen, and determining whether or not the QR code is altered.
In the process of identifying the QR code (10) by using the camera, whether the QR code is changed or not can be judged, and a special application program (30) for switching the interface of the mobile device (50) with the screen to a special interface (40) can be downloaded, or the QR code can be guided to a special website for carrying out the whole process.
Step (b): switching the interface to a pseudo-alteration confirmation interface:
after the first determination of whether or not the screen is pseudo-altered is made and the non-pseudo-altered QR code (10) is confirmed for the first time, a process of switching the interface of the mobile device (50) having the screen to the dedicated interface (40) necessary for the second determination may be performed.
Step (c): and a step of visually confirming whether or not the pattern printed on the QR code (10) is altered by using a false alteration confirmation interface:
after the interface of a mobile device (50) having a screen is switched to a dedicated interface (40) required for the second determination, light (60) generated on the switched dedicated interface (40) is irradiated to the QR code (10), and the presence or absence of the identification pattern (20) or the presence or absence of pattern matching is used to perform the second determination of whether or not the pattern is artificially altered.
Here, since light irradiated from a mobile device (50) having a screen has a polarization characteristic, it is preferable that the dedicated interface (40) is rotated at an angle of 90 degrees and simultaneously the light (60) generated from the interface is irradiated to the identification pattern (20), and the presence or absence of the identification pattern (20) and whether the patterns match or not are determined.
The present invention can have other effects even if the effects are not described in the present specification, and new effects that cannot be seen in the prior art can be obtained from the organic combination relationship among the above-described structures.
Meanwhile, the embodiment illustrated in the drawings can be modified into other forms, and structures or equivalent substitutions within the scope of claims of the present invention can also be applied, but the embodiment made without creative efforts belongs to the protection scope of the present invention.
