[0035] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are used only to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0036] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0037] An anti-counterfeiting label is provided in the embodiments of this disclosure, such as Figure 1 As shown, the anti-counterfeiting label may include: an OLED (Organic Light-Emitting Diode) display 11.

[0038] The OLED display 11 includes at least one color-changing region 111, and the OLED display 11 has a color conversion layer or color filter layer at each color-changing region 111.

[0039] The color conversion layer includes a color conversion region and a first blank region, which cover pixels of different color types. The color of the light emitted by the color conversion region is different from the color of the light emitted by the covered pixels. The color filter layer includes a color filter region and a second blank region, which cover pixels of different color types. The color of the light allowed to pass through the color filter region is different from the color of the light emitted by the covered pixels.

[0040] The anti-counterfeiting label is constructed using an OLED display 11 that includes at least one color-changing region 111. The color-changing region 11 is further configured with a color conversion layer or a color filter layer. Specifically, the color conversion layer includes a color type different from the pixels covered by a first blank area, and the color filter layer includes a color filter area different from the pixels covered by a second blank area. Furthermore, the color of the light emitted by the color conversion region differs from the color of the light emitted by the covered pixels, and the color of the light allowed to pass through the color filter area differs from the color of the light emitted by the covered pixels. This allows the color-changing region to display different color patterns from both front and side viewing angles, thus achieving an anti-counterfeiting effect. Moreover, anti-counterfeiting labels based on OLED displays are highly difficult to counterfeit.

[0041] It should be noted that, Figure 1Only take the example of OLED display 11 including 12 display areas and 2 color-changing areas. In fact, the number of display areas included in OLED display 11 is not limited by the present disclosure, and can be 1, or 2, or 3, and so on. In addition, all of the display areas included in OLED display 11 can be color-changing areas, or some of them can be color-changing areas, and the color-changing areas can be distributed in an interval, or connected, or both.

[0042] In one embodiment, each display area of OLED display 11 displays a preset sub-pattern when powered on.

[0043] In one embodiment, all display areas of OLED display 11 display a combination of patterns that form a preset target pattern when powered on.

[0044] By configuring the display areas of OLED display 11 to display respective sub-patterns, and the combination of patterns displayed by each display area to form a target pattern, the difficulty of counterfeiting the anti-counterfeiting label implemented based on OLED display 11 can be increased, which is more conducive to anti-counterfeiting identification.

[0045] In one embodiment, the display of each display area of OLED display 11 to display a preset sub-pattern when powered on, and the combination of patterns displayed by each display area to form a preset target pattern can be achieved by patterning the electrode structure of the substrate of OLED display 11.

[0046] In one embodiment, the substrate of OLED display 11 is a flexible substrate. In the case where the substrate of OLED display 11 is a flexible substrate, a schematic diagram of the patterned electrode structure of the flexible substrate can be as shown in Figure 2 , wherein the pixel defining layer 201 and the pixel defining layer 202 pattern the electrode structure on the flexible substrate 203, so that the display areas of OLED display 11 can display a preset sub-pattern when powered on, and the combination of patterns displayed by each display area can form a preset target pattern.

[0047] In one embodiment, the material used to make the pixel defining layer can be PI, or PAN (Polyacrylonitrile, polyacrylonitrile)

[0048] In one embodiment, the material used to make the flexible substrate can include one or more of PET (Polyethylene Terephthalate, polyethylene terephthalate), PI (Polyimide, polyimide), and PC (Polycarbonate, polycarbonate).

[0049] In one embodiment, the material for making electrode structure in OLED display 11 can be Ag (silver) / ITO (Indium Tin Oxide), or Mo (Metal Oxide) / ITO, or other materials.

[0050] In one embodiment, OLED display 11 can be a display prepared on the basis of a flexible substrate, and an OLED structure. The OLED structure can include HIL (Hole Injection Layer), HTL (Hole Transport Layer), EBL (Electron Injection Layer), EML (Emissive Layer), HBL (Hole Blocking Layer), ETL (Electron Transport Layer), and EIL (Electron Injection Layer).

[0051] In one embodiment, as shown in FIG. 3, OLED display 11 has a color conversion layer at a color changing region, and has two types of pixels including first pixel 301 and second pixel 302. Color conversion region 303 covers first pixel 301, and first blank region 304 covers second pixel 302. First pixel 301 and second pixel 302 emit light of different colors. Figure 3

[0052] It should be noted that the black region between color conversion region 303 and first blank region 304 in the color conversion layer can prevent light from passing through, and also will not be excited by light. In subsequent embodiments, the black region between the color conversion region and the first blank region, or between each sub-color conversion region, or between the color film region and the second blank region, or between each sub-color film region can prevent light from passing through, and also will not be excited by light.

[0053] In one embodiment, first pixel 301 and second pixel 302 are one of red, green, and blue pixels, and first pixel 301 and second pixel 302 are different. For example, first pixel is a red pixel, and second pixel is a green pixel.

[0054] ​Since the color conversion region emits light with a color different from the color of the light emitted by the covered pixel, the light emitted by the first pixel, after exciting the color conversion region, emits light of the first color, and the light emitted by the second pixel, after passing through the first blank region, maintains the color unchanged and emits light of the second color. Accordingly, at the normal viewing angle, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region is a color formed by combining the first color and the second color.

[0055] At the side viewing angle, the light emitted by the first pixel 301 can also exit through the first blank region 304, thereby maintaining the color unchanged and emitting light of the third color. Accordingly, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region is a color formed by combining the first color, the second color, and the third color.

[0056] The color formed by combining the first color, the second color, and the third color is different from the color formed by combining the first color and the second color, that is, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region is different at the normal viewing angle and the side viewing angle.

[0057] Taking an example in which the color conversion region is used to emit green light, the first pixel is a blue pixel, and the second pixel is a red pixel, at the normal viewing angle, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region is yellow formed by combining green and red. At the side viewing angle, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region is white formed by combining green, red, and blue.

[0058] It should be noted that, for the color-changing region Figure 3 In the corresponding embodiment, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region is different when observed at different side viewing angles. When the angle of the side viewing angle changes, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region can change, and as the side viewing angle approaches the normal viewing angle, the color of the pattern gradually changes to yellow.

[0059] In subsequent embodiments, at different angles of the side viewing angle, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region gradually changes to the color at the normal viewing angle as the side viewing angle approaches the normal viewing angle.

[0060] It should also be noted that Figure 3 The direction of the side viewing angle shown in the embodiments is only exemplary, and the side viewing angle can also be in other directions. For example, the side viewing angle in another direction can be as shown in FIG. 6. Figure 4 Figure 4 The side viewing angle shown is also only exemplary.

[0061] In one embodiment, as shown in FIG. 7, the color conversion region is used to emit green light, the first pixel is a blue pixel, and the second pixel is a red pixel. Figure 5 ​As shown, the OLED display 11 has a color conversion layer at the color-changing region, and has three pixel types including the third pixel 501, the fourth pixel 502 and the fifth pixel 503, in which case the color conversion region 504 covers the third pixel 501, and the first blank region 505 covers the fourth pixel 502 and the fifth pixel 503; wherein the colors of the light emitted by the third pixel 501, the fourth pixel 502 and the fifth pixel 503 are all different.

[0062] In one embodiment, the third pixel 501, the fourth pixel 502 and the fifth pixel 503 are all one of red pixels, green pixels and blue pixels, and are all different. For example, the third pixel 501 is a red pixel, the fourth pixel 502 is a green pixel, and the fifth pixel 503 is a blue pixel.

[0063] Since the color of the light emitted by the color conversion region 504 under excitation is different from the color of the light emitted by the pixel covered by the color conversion region 504, after the light emitted by the third pixel 501 excites the color conversion region 504, the color conversion region 504 emits light of a fourth color, and the colors of the light emitted by the fourth pixel 502 and the fifth pixel 503 remain unchanged after passing through the first blank region 505. Accordingly, at the normal viewing angle, the color of the sub-pattern displayed by the OLED display 11 at the color-changing region is the color formed by combining the fourth color with the colors of the light emitted by the fourth pixel 502 and the fifth pixel 503.

[0064] The color of the light emitted by the color conversion region 504 under excitation can be the same as one of the colors of the light emitted by the fourth pixel 502 and the fifth pixel 503, or can be different.

[0065] At the side viewing angle, the light emitted by the third pixel 501 can directly exit through the first blank region 505, and accordingly, the color of the sub-pattern displayed by the OLED display 11 at the color-changing region is the color formed by combining the fourth color with the colors of the light emitted by the third pixel 501, the fourth pixel 502 and the fifth pixel 503.

[0066] In the case where the color of the light emitted by the color conversion region 504 under excitation is the same as one of the colors of the light emitted by the fourth pixel 502 and the fifth pixel 503, at the normal viewing angle, the color of the pattern displayed by the OLED display 11 at the color-changing region is formed by mixing two colors, and at the side viewing angle, the color of the pattern displayed by the OLED display 11 at the color-changing region is formed by mixing three colors. Therefore, at the normal viewing angle and the side viewing angle, the color of the pattern displayed by the OLED display 11 at the color-changing region is different.

[0067] When the color of the light emitted by the color conversion region 504 differs from the color of the light emitted by the fourth pixel 502 and the fifth pixel 503, the pattern displayed by the OLED display 11 in the color-changing region is formed by mixing three colors when viewed from the front, and by mixing four colors when viewed from the side. Therefore, the color of the pattern displayed by the OLED display 11 in the color-changing region differs between the front and side views.

[0068] In one embodiment, such as Figure 6 As shown, the OLED display 11 has a color conversion layer in the color-changing area, and has three pixel types including the third pixel 601, the fourth pixel 602 and the fifth pixel 603. The color conversion area 604 covers the third pixel 601 and the fourth pixel 602, and the first blank area 605 covers the fifth pixel 604. The colors of the light emitted by the third pixel 601, the fourth pixel 602 and the fifth pixel 603 are all different.

[0069] In one embodiment, the third pixel 601, the fourth pixel 602, and the fifth pixel 603 are all one of red, green, and blue pixels, and none of them are the same. For example, the third pixel 601 is a green pixel, the fourth pixel 602 is a red pixel, and the fifth pixel 603 is a blue pixel.

[0070] Because the color of the light emitted by the color conversion region 604 is different from the color of the light emitted by the pixels it covers, the light emitted by the third pixel 601 and the fourth pixel 601, after exciting the color conversion region 604, emits a fifth color of light. The light emitted by the fifth pixel 603, after passing through the first blank region 605, maintains the color change. Accordingly, at a normal viewing angle, the color of the sub-pattern displayed by the OLED display 11 in this color-changing region is the color formed by the combination of the fifth color and the color of the light emitted by the fifth pixel 603.

[0071] The color of the light emitted by the color conversion region 604 can be the same as or different from the color of the light emitted by the fifth pixel 603.

[0072] From the first side view, the light emitted by the fourth pixel 602 can be directly emitted through the first blank area 605. Correspondingly, the color of the sub-pattern displayed by the OLED display 11 in the color-changing area is the color formed by combining the colors of the fifth color, the fourth pixel 602 and the fifth pixel 603.

[0073] From the second side view, the light emitted by the third pixel 601 can be directly emitted through the first blank area 605. Accordingly, the color of the sub-pattern displayed by the OLED display 11 in the color-changing area is the color formed by combining the colors of the fifth color, the third pixel 601 and the fifth pixel 603.

[0074] When the color of the light emitted from the color conversion region 604 is the same as the color of the light emitted from the fifth pixel 603, in a frontal viewing angle, the color of the pattern displayed by the OLED display 11 in the color-changing region is the fifth color (i.e., the color of the light emitted by the fifth pixel). In a side viewing angle (first side-view and second side-view), the color of the pattern displayed by the OLED display 11 in the color-changing region is formed by a mixture of the two colors. Therefore, the color of the pattern displayed by the OLED display 11 in the color-changing region is different in frontal and side-view.

[0075] When the color of the light emitted by the color conversion region 604 differs from the color of the light emitted by the fifth pixel 603, the color of the pattern displayed by the OLED display 11 in the color-changing region is formed by a mixture of two colors in a frontal viewing angle, and by a mixture of three colors in a side viewing angle (first side viewing angle and second side viewing angle). Therefore, the color of the pattern displayed by the OLED display 11 in the color-changing region differs between a frontal viewing angle and a side viewing angle.

[0076] From a first viewing angle, the color of the pattern displayed by the OLED display 11 in the color-changing area is formed by mixing three colors: a fifth color, a fourth pixel 602, and a fifth pixel 603. From a second viewing angle, the color of the pattern displayed by the OLED display 11 in the color-changing area is also formed by mixing three colors: a fifth color, a third pixel 602, and a fifth pixel 603. Regardless of whether the colors of the light emitted by the fifth color and the fifth pixel 603 are the same, the color of the pattern displayed by the OLED display 11 in the color-changing area is different from both the first and second viewing angles.

[0077] By displaying sub-patterns of different colors in the color-changing area under different side views, the counterfeiting difficulty of the anti-counterfeiting label based on the OLED display 11 can be further increased, which is more conducive to anti-counterfeiting identification.

[0078] In one embodiment, such as Figure 7 As shown, the color conversion region 604 includes a first sub-color conversion region 6041 and a second sub-color conversion region 6042. The first sub-color conversion region 6041 covers the third pixel 601, and the second sub-color conversion region 6042 covers the fourth pixel 602. The colors of the light emitted by the first sub-color conversion region 6041 and the second sub-color conversion region 6042 are different.

[0079] Since the color conversion region 604 is excited by light of a color different from the color of the light emitted by the pixel covered, the third pixel 601 emits light of a sixth color after exciting the color conversion region 6041, the fourth pixel 601 emits light of a seventh color after exciting the color conversion region 6042, and the fifth pixel 603 maintains the color after passing through the first blank region 605. Accordingly, at the normal viewing angle, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region is a color formed by combining the sixth color, the seventh color, and the color of the light emitted by the fifth pixel 603.

[0080] The color of the light emitted by the fifth pixel 603 can be the sixth color or the seventh color, or the color of the light emitted by the fifth pixel 603 is different from the sixth color and the seventh color.

[0081] At the first side viewing angle, the light emitted by the fourth pixel 602 can directly exit through the first blank region 605, and accordingly, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region is a color formed by mixing the sixth color, the seventh color, the color of the light emitted by the fourth pixel 602, and the color of the light emitted by the fifth pixel 603.

[0082] The color of the light emitted by the fourth pixel 602 is different from the sixth color. If the color of the light emitted by the fourth pixel 602 is the same as the sixth color, at the first side viewing angle, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region is a color formed by mixing the sixth color, the seventh color, and the color of the light emitted by the fifth pixel 603. This is the same as the color of the sub-pattern displayed by the OLED display 11 in the color-changing region at the normal viewing angle, thereby easily making the colors of the sub-patterns at the normal viewing angle and the first side viewing angle similar or the same.

[0083] In the case where the color of the light emitted by the fourth pixel 602 is different from the sixth color, the color of the sub-pattern displayed by the color-changing region at the first side viewing angle is different from that at the normal viewing angle.

[0084] At the second side viewing angle, the light emitted by the third pixel 601 can directly exit through the first blank region 605, and accordingly, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region is a color formed by mixing the sixth color, the seventh color, the color of the light emitted by the third pixel 601, and the color of the light emitted by the fifth pixel 603.

[0085] In this case, the color of the light emitted by the third pixel 601 is different from the seventh color. If the color of the light emitted by the third pixel 601 is the same as the seventh color, then under the first side view, the color of the sub-pattern displayed by the OLED display 11 in the color-changing area is formed by mixing the colors of the sixth color, the seventh color, and the light emitted by the fifth pixel 603. This is the same as the color composition of the sub-pattern displayed by the OLED display 11 in the color-changing area under the normal view, thus making it easy for the color of the sub-pattern displayed in the color-changing area under the normal view and the second side view to be similar or the same.

[0086] When the color of the light emitted by the third pixel 601 is different from the seventh color, the color of the sub-pattern displayed in the color-changing area under the second side view is different from that under the front view.

[0087] Furthermore, when the color of the light emitted by the third pixel 601 is different from the seventh color, and the color of the light emitted by the fourth pixel 602 is different from the sixth color, the color of the sub-pattern displayed by the OLED display 11 in the color-changing area is different from the first side view and the second side view.

[0088] In one embodiment, such as Figure 8 As shown, the OLED display 11 has a color filter layer in the color-changing area, and has two pixel types including a first pixel 801 and a second pixel 802. The color filter area 803 covers the first pixel, and the second blank area 804 covers the second pixel. The first pixel 801 and the second pixel 802 emit light of different colors.

[0089] In one embodiment, both the first pixel 801 and the second pixel 802 are one of a red pixel, a green pixel, and a blue pixel, and the first pixel 801 and the second pixel 802 are different. For example, the first pixel is a red pixel and the second pixel is a green pixel.

[0090] Because the color of light allowed to pass through the color filter area is different from the color of light emitted by the pixels it covers, light emitted from the first pixel 801 cannot pass through the color filter area 803, while light emitted from the second pixel 802 can pass directly through the second blank area 804. Therefore, at a normal viewing angle, the color of the sub-pattern displayed by the OLED display 11 in this color-changing area is the color of the light emitted by the second pixel 802.

[0091] From a side view, the light emitted by the first pixel 801 can be emitted through the second blank area 804, and the light emitted by the second pixel 802 can also be emitted directly through the second blank area 804. At this time, the color of the sub-pattern displayed by the OLED display 11 in the color-changing area is the color after the light emitted by the first pixel 801 and the second pixel 802 are mixed.

[0092] The color of the light allowed to pass through the color filter region 803 can be the same as or different from the color of the light emitted by the second pixel 802. Regardless of whether the color is the same or different, the color of the sub-pattern displayed by the OLED display 11 at the color-changing region at the side view angle is the color of the light emitted by the first pixel 801 mixed with the color of the light emitted by the second pixel 802. Correspondingly, regardless of whether the color is the same or different, the color of the sub-pattern displayed by the OLED display 11 at the color-changing region at the side view angle is different from the color of the sub-pattern displayed by the OLED display 11 at the color-changing region at the front view angle.

[0093] It should be noted that the color of the light allowed to pass through the color filter region 803 can be the same as or different from the color of the light emitted by the second pixel 802. In both cases, the color of the sub-pattern displayed by the OLED display 11 at the color-changing region at the same side view angle is different.

[0094] In an embodiment, as shown in FIG. 9, the OLED display has a color filter filter layer at the color-changing region, and has three types of pixels including a third pixel 901, a fourth pixel 902, and a fifth pixel 903. The color filter region 904 covers the third pixel 901, and the second blank region 905 covers the fourth pixel 902 and the fifth pixel 903. The color of the light emitted by the third pixel 901, the fourth pixel 902, and the fifth pixel 903 is different. Figure 9

[0095] The third pixel 901, the fourth pixel 902, and the fifth pixel 903 can be one of a red pixel, a green pixel, and a blue pixel, and the third pixel 901, the fourth pixel 902, and the fifth pixel 903 are different. For example, the third pixel 901 is a red pixel, the fourth pixel 902 is a green pixel, and the fifth pixel 903 is a red pixel.

[0096] Since the color of the light allowed to pass through the color filter region is different from the color of the light emitted by the pixel covered by the color filter region, the light emitted by the third pixel 901 cannot pass through the color filter region 904, and the light emitted by the fourth pixel 902 and the fifth pixel 903 can directly pass through the second blank region 905. Therefore, at the front view angle, the color of the sub-pattern displayed by the OLED display 11 at the color-changing region is the color of the light emitted by the fourth pixel 902 mixed with the color of the light emitted by the fifth pixel 903.

[0097] At the first side view angle and the second side view angle, the light emitted by the third pixel 901 can pass through the second blank region 905, and the light emitted by the fourth pixel 902 and the fifth pixel 903 can directly pass through the second blank region 905. At this time, the color of the sub-pattern displayed by the OLED display 11 at the color-changing region is the color of the light emitted by the third pixel 901 mixed with the color of the light emitted by the fourth pixel 902 and the fifth pixel 903.

[0098] ​It should be noted that the color of the light emitted by the fifth pixel 903 can be the same as the color of the light allowed to pass through the color film region 904, or can be different. In both cases, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region at the first side view angle is different from that at the normal view angle. In both cases, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region at the first side view angle is different.

[0099] The color of the light emitted by the fourth pixel 902 can be the same as the color of the light allowed to pass through the color film region 904, or can be different. In both cases, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region at the second side view angle is different from that at the normal view angle. In both cases, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region at the second side view angle is different.

[0100] In one embodiment, as shown in FIG. 10, the OLED display 11 has a color film filter layer at the color-changing region, and has three types of pixels including the third pixel 901, the fourth pixel 902, and the fifth pixel 903. In this case, the color film region 1001 covers the third pixel 901 and the fourth pixel 902, and the second blank region 1002 covers the fifth pixel 903. The colors of the light emitted by the third pixel 901, the fourth pixel 902, and the fifth pixel 903 are all different. Figure 10

[0101] Since the color of the light allowed to pass through the color film region is different from the color of the light emitted by the pixel covered by the color film region. Therefore, the light emitted by the third pixel 901 and the fourth pixel 902 cannot pass through the color film region 1001, while the light emitted by the fifth pixel 903 can directly pass through the second blank region 1002. Therefore, at the normal view angle, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region is the color of the light emitted by the fifth pixel 903.

[0102] At the first side view angle, the light emitted by the fourth pixel 902 can pass through the second blank region 1002, the light emitted by the fifth pixel 903 can also directly pass through the second blank region 1002, and the light emitted by the third pixel 901 cannot pass through the color film region 1001. At this time, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region is the mixed color of the light emitted by the fourth pixel 902 and the fifth pixel 903.

[0103] Therefore, at the normal view angle and the first side view angle, the color of the sub-pattern displayed by the OLED display 11 in the color-changing region is different.

[0104] ​At the second side view angle, the light emitted by the third pixel 901 can be emitted through the second blank area 1002, the light emitted by the fifth pixel 903 can also be directly emitted through the second blank area 1002, and the light emitted by the fourth pixel 902 cannot be emitted through the color film area 1001. At this time, the color of the sub-pattern displayed by the OLED display 11 in the color-changing area is the color of the mixed light emitted by the third pixel 901 and the fifth pixel 903.

[0105] Therefore, it can be seen that the color of the sub-pattern displayed by the OLED display 11 in the color-changing area is different at the normal view angle and the second side view angle, and the color of the sub-pattern displayed by the OLED display 11 in the color-changing area is also different at the second side view angle and the first side view angle.

[0106] In one embodiment, as shown in FIG. 10, the color film area 1001 includes a first sub-color film area 1101 and a second sub-color film area 1102, the first sub-color film area 1101 covers the third pixel 901, and the second sub-color film area 1102 covers the fourth pixel 902; the first sub-color film area 1101 and the second sub-color film area 1102 allow light of different colors to pass through. Figure 11

[0107] Among them, the color of the light allowed to pass through the first sub-color film area 1101 can be the same as or different from the color of the light emitted by the fourth pixel 902 or the fifth pixel 903. The color of the light allowed to pass through the second sub-color film area 1102 can be the same as or different from the color of the light emitted by the third pixel 901 or the fifth pixel 903.

[0108] Since the color of the light allowed to pass through the color film area is different from the color of the light emitted by the covered pixel, the light emitted by the third pixel 901 and the fourth pixel 902 cannot pass through the color film area 1001, and the light emitted by the fifth pixel 903 can directly pass through the second blank area 1002. Therefore, at the normal view angle, the color of the sub-pattern displayed by the OLED display 11 in the color-changing area is the color of the light emitted by the fifth pixel 903.

[0109] ​From a first-side viewing angle, light emitted from the fourth pixel 902 can pass through the second blank area 1002, and light emitted from the fifth pixel 903 can also directly pass through the second blank area 1002. At this time, the color of the sub-pattern displayed by the OLED display 11 in this color-changing area is at least the color resulting from the mixture of the light emitted from the fourth pixel 902 and the fifth pixel 903. Therefore, the color of the sub-pattern displayed by the OLED display 11 in this color-changing area differs between the first-side viewing angle and the frontal viewing angle. Furthermore, when the color of the light allowed to pass through the second sub-color filter area 1102 is the same as the color of the light emitted by the third pixel 901, the light emitted by the third pixel 901 can pass through the second sub-color filter area 1102. In this case, the color of the sub-pattern formed by the mixture also includes the color of the light emitted by the third pixel 901.

[0110] From a second-side viewing angle, light emitted from the third pixel 901 can pass through the second blank area 1002, and light emitted from the fifth pixel 903 can also pass directly through the second blank area 1002. At this time, the color of the sub-pattern displayed by the OLED display 11 in this color-changing area is at least the color resulting from the mixture of the light emitted from the third pixel 901 and the fifth pixel 903. Therefore, the color of the sub-pattern displayed by the OLED display 11 in this color-changing area differs between the second-side viewing angle and the normal viewing angle. Furthermore, when the color of the light allowed to pass through the first sub-color filter area 1101 is the same as the color of the light emitted by the fourth pixel 902, the light emitted by the fourth pixel 902 can pass through the first sub-color filter area 1101. In this case, the color mixed to form the sub-pattern also includes the color of the light emitted by the fourth pixel 902.

[0111] In one embodiment, when the OLED display 11 is powered on, at least one color-changing area displays a preset target pattern from a side view.

[0112] In one embodiment, such as Figure 12 As shown, the anti-counterfeiting label includes an OLED display 11 and a thin-film battery 121. The thin-film battery 121 supplies power to the OLED display 11 via an electrical connection wire 1211.

[0113] In one embodiment, the anti-counterfeiting label further includes a back plate 122, which is used to fix the OLED display 11 and the thin-film battery 121, and to combine the anti-counterfeiting label with the object requiring anti-counterfeiting. For example, the back plate 122 can be used to combine the anti-counterfeiting label with the object requiring anti-counterfeiting by adhesive. The back plate 122 can also be configured according to the object requiring anti-counterfeiting, so that the anti-counterfeiting label can be better combined with the object requiring anti-counterfeiting.

[0114] In another embodiment, the OLED display 11, the thin film battery 121 and the electric connecting wire 1211 are encapsulated in a shell, and the shell is light-transmissive at the display area of the OLED display 11. When the anti-counterfeiting label is used for anti-counterfeiting, the shell can be combined with an object that needs to be anti-counterfeited.

[0115] It should be noted that the anti-counterfeiting label provided by the embodiments of the present disclosure can be combined with an object that needs to be anti-counterfeited in various ways, so that the object can achieve anti-counterfeiting based on the anti-counterfeiting label.

[0116] The OLED-based anti-counterfeiting label has the characteristics of high brightness, long service life, high contrast and the like, and therefore the OLED-based anti-counterfeiting label can have wide application in the field of anti-counterfeiting. For example, commodity anti-counterfeiting, the OLED-based anti-counterfeiting label can be used to add variable text, numbers, patterns and the like special effects on commodity packaging, so as to achieve the purpose of anti-counterfeiting. For another example, the anti-counterfeiting label is pasted on a medicine bottle cap, which can provide unique anti-counterfeiting protection. For another example, certificate anti-counterfeiting, in order to prevent the certificate from being counterfeited, the OLED-based anti-counterfeiting label can be used as an auxiliary means, which can be used for the display of personal information, certificate validity period, portrait and the like information and some special dynamic effects. For another example, ticket anti-counterfeiting, the ticket field is also an important application scene of the anti-counterfeiting label, and the OLED-based anti-counterfeiting label can be used for the anti-counterfeiting of various tickets, such as lottery tickets, train tickets and the like, and the variable special effects and information on the ticket surface can be increased to achieve the effect of anti-counterfeiting.
