現有技術中的遊戲牌,例如撲克牌或桌遊卡牌等都是在紙質牌面上印刷圖案,形式單一,為了增加遊戲的趣味性在很多方面進行發掘,但是,還沒有想到用微奈米結構在透明的塑膠膜片上設計卡牌上的圖案。The game cards in the prior art, such as playing cards or board game cards, are all printed with patterns on the card surface of the paper, in a single form. In order to increase the fun of the game, many aspects have been explored. However, it has not been thought of using micronano The structure designs the pattern on the card on the transparent plastic film.
本發明的目的在於克服現有技術之不足,提供一種微奈米結構卡牌,以此增加用其製作的遊戲牌或成套卡牌的趣味性。The purpose of the present invention is to overcome the deficiencies of the prior art and provide a card with a micro-nano structure, so as to increase the interestingness of the game card or the set of cards made by the card.

There is a micro-nano structure on the surface, and the micro-nano structure carries distinguishing information. The micro-nano structure card includes several cards, and the micro-nano structure on the structural surface of each card carries the The distinguishing features are different, but the patterns formed by the distinguishing features on each card are logically related in content, so that all cards form a set of cards.
在上述兩個技術方案中,進一步地,還有如下優選措施: 一套卡牌組中的各張卡牌上微奈米結構的區別特徵不同的各張卡牌,在普通光線下肉眼看各張卡牌無差異使之無法分辨;及/或,在普通光線下肉眼下,360度全角度防窺,即在任何角度下一套卡牌組中所有卡牌上顯現的霧面微奈米結構在視覺上是一樣的。In the above two technical solutions, further, there are the following preferred measures: Each card in a deck of cards with different distinguishing characteristics of micro-nanostructures is indistinguishable from the naked eye under ordinary light; and/or, under ordinary light Under the naked eye, the 360-degree full-angle anti-peep, that is, the matte micro-nano structure displayed on all cards in the next deck of cards at any angle is visually the same.

所述微奈米結構為衍射光學元件(Diffractive Optical Elements,簡稱DOE)或全息衍射光學元件(Holographic Diffractive Optical Elements,簡稱HDOE)。The micro-nano structures are diffractive optical elements (Diffractive Optical Elements, DOE for short) or holographic diffractive optical elements (Holographic Diffractive Optical Elements, HDOE for short).
所述塑膠膜片由有色或無色透明材料製成。The plastic film is made of colored or colorless transparent material.
所述結構面上的微奈米結構可以是微米結構,也可以是奈米結構。The micro-nano structures on the structural surface can be either micro-structures or nano-structures.
所述結構面上的微奈米結構的單元大小在2毫米2毫米以內,該單元在卡牌的結構面上重複排列。The unit size of the micro-nano structures on the structural surface is 2 mm Within 2 mm, the unit is repeated on the structural surface of the card.

卡牌上的微結構在卡牌上重複排列,使得在使用中使用點光源只要照射在卡牌上,就可以呈現出其上的區別特徵即其中的特定圖案。The microstructures on the card are arranged repeatedly on the card, so that when a point light source is used in use, as long as the card is irradiated, the distinguishing feature on the card, that is, the specific pattern in it can be presented.
所述卡牌組可以構成一副遊戲牌,例如可以是一副撲克牌,或者是一副桌遊牌,例如一副三國殺的桌遊牌,或者是其他遊戲卡牌。除此之外,所述卡牌組也可以是一套內容上有關聯性的卡牌,例如一套108張卡牌用微奈米結構描繪的水滸傳中一百單八將的圖片,或者描繪紅樓夢金陵十二釵的12張圖片等等。在銷售中,可以成套出售,例如撲克牌等,也可以分別銷售,例如商業促銷中將一套金陵十二釵的卡牌分次出售。The card set may constitute a deck of game cards, for example, a deck of playing cards, or a deck of board game cards, such as a deck of Three Kingdoms Kill board game cards, or other game cards. In addition, the card set may also be a set of related cards, such as a set of 108 cards depicting a picture of one hundred and eight generals in the Water Margin with a micro-nano structure, or 12 pictures depicting the twelve hairpins of Jinling, Dream of Red Mansions, etc. In the sales, it can be sold in sets, such as playing cards, etc., or it can be sold separately. For example, in a commercial promotion, a set of cards of Jinling Twelve Hairpins is sold in batches.
優選地,在所述結構面設有熱壓成型或UV轉印或奈米壓印的微奈米結構。所述微奈米結構的紋路根據圖案設計決定,可以是對稱的,例如撲克牌等對稱圖案,微奈米結構就是對稱的,也可以是不對稱的。Preferably, a micro-nano structure formed by thermocompression or UV transfer printing or nano-imprinting is provided on the structure surface.

優選地,所述結構面上的微奈米結構是3D的微/奈米結構。Preferably, the micro-nano structures on the structural surface are 3D micro/nano structures.
用微奈米結構(DOE)做遊戲牌,如果按照常規卡片的做法,即每張卡牌上的微奈米結構載有的區別特徵都是不一樣的,雖然微結構(DOE)具有一定的防窺性能,但是在無照射光即普通光線下肉眼看,卡牌的圖案複雜程度不同,會顯示出不同的視覺的霧面色差,這種卡牌因為有視覺的霧面深淺色差,玩家會通過卡牌色差的不同猜測出大小牌,由此會影響到遊戲的公正性,從而使得本發明提供的卡牌作為遊戲牌不方便使用。Using micro-nano structure (DOE) to make playing cards, if you follow the practice of conventional cards, that is, the distinguishing features carried by the micro-nano structure on each card are different, although the micro-structure (DOE) has certain characteristics. Anti-peep performance, but when viewed with the naked eye under normal light without illumination, the pattern of the card is different, and it will show different visual fog color difference. Because of the visual fog color difference of this card, players will The big and small cards are guessed through the difference in the color difference of the cards, which will affect the fairness of the game, thus making the cards provided by the present invention inconvenient to use as game cards.
因此,區別特徵不同的各張卡牌在普通光線下肉眼看,360度全角度防窺,即卡牌上圖案的複雜程度不同但其上的霧面(亞面)沒有差別,是作為尤其是遊戲牌最好能夠具備的特點。Therefore, each card with different distinguishing characteristics can be seen with the naked eye under ordinary light, and the 360-degree full-angle privacy protection, that is, the complexity of the pattern on the card is different, but the matte surface (sub-surface) on it is not different. The best characteristics of a game card.

在一套卡牌組中,各張卡牌上的微奈米結構的蝕刻深度不盡相同。In a deck of cards, the micro-nanostructures on each card are etched to different depths.
所述微奈米結構的蝕刻深度根據各張卡牌圖案的複雜程度而不盡相同,圖案較簡單的卡牌上微奈米結構的蝕刻深度較深,圖案較複雜的卡牌上微奈米結構的蝕刻深度較淺。The etching depth of the micro-nano structure varies according to the complexity of the pattern of each card. The etching depth of the micro-nano structure is deeper on the card with a simpler pattern, and the micro-nano structure on the card with a more complex pattern is deeper. The etch depth of the structure is shallow.

Preferably 1 to 3 times of photolithography are used to form second-order, fourth-order and eighth-order micro-nano structures.
通過上述的調整,可以使得本卡牌在除了照射光下,都不能看出結構面上微奈米結構產生的霧面有差別。Through the above adjustment, it is possible to make this card unable to see the difference in the haze generated by the micro-nano structure on the structure surface except under the irradiated light.
手段3:調整塑膠膜片的顏色,即所述塑膠膜片由有色透明材料製成。Method 3: Adjust the color of the plastic film, that is, the plastic film is made of a colored transparent material.
通過用有色的透明塑膠膜片製作本卡牌,降低有色透明材料的透光率,也可以降低視覺色差,使得卡牌上因圖案複雜程度不同導致的霧面差別得到改善。By making the card with colored transparent plastic film, the light transmittance of the colored transparent material can be reduced, and the visual chromatic aberration can also be reduced, so that the difference in the fog surface caused by the complexity of the pattern on the card can be improved.
手段4:在塑膠膜片上設置鍍膜層。Method 4: A coating layer is provided on the plastic film.
即在塑膠膜片上設置一鍍膜層,以改變卡牌的視覺色差。該鍍膜層優選為有色透明的鍍膜。That is, a coating layer is arranged on the plastic film to change the visual color difference of the card. The coating layer is preferably a colored and transparent coating.

為方便理解本發明的技術構思及發明精神,以下針對本發明舉不同實施例進行說明,惟該等實施例僅為說明本發明技術構思的例示,並非用以限制本發明的保護範圍,在此先行說明。In order to facilitate the understanding of the technical idea and the inventive spirit of the present invention, the present invention will be described below with different embodiments, but these embodiments are only examples for illustrating the technical idea of the present invention, and are not intended to limit the protection scope of the present invention. Explanation in advance.
實施例一:
參見圖1所示,本發明的一種微奈米結構卡牌,包括若干個無色或有色透明或半透明塑膠膜片1製成的卡牌本體,構成一副撲克牌,有54張卡牌本體,所述塑膠膜片1的結構面設有熱壓成型或UV轉印或奈米壓印的微奈米結構2,微奈米結構2為衍射光學元件(Diffractive Optical Elements)或全息衍射光學元件(Holographic Diffractive Optical Elements)。微奈米結構2上載有區別資訊。Example 1:
Referring to Fig. 1, a micro-nano structured card of the present invention includes a plurality of card bodies made of colorless or colored transparent or translucent
在本實施例中,各張卡牌上的區別特徵為撲克牌的圖案,包括紅心、黑桃、方塊和梅花四種花色、每種花色從1〜13的圖案,還有大小王(鬼牌)。In this embodiment, the distinguishing feature on each card is the pattern of playing cards, including four suits of hearts, spades, diamonds and clubs, patterns of each suit from 1 to 13, and big and small kings (ghost cards). ).
各種花色,從1到13,圖案越來越複雜。如果用常規的微奈米結構設計方式,用同樣的微奈米結構來製作,各張牌上的微奈米結構在塑膠膜片1上形成的圖案構成的霧面在普通光線下,用肉眼能夠看出色差,根據色差能夠推測出牌的大小,這樣防窺性就比較差,使得遊戲失去公正性。Various suits, from 1 to 13, with increasingly complex patterns. If the conventional micro-nano structure design method is used, and the same micro-nano structure is used to manufacture, the fog surface formed by the pattern formed by the micro-nano structure on each card on the
為了提高卡牌的防窺性,也就是不管卡牌上的圖案簡單還是複雜,肉眼看去沒有色差,看不出差別,本發明創造性地提出,對於各種卡牌上結構面上的微奈米結構做如下調整: 調整微奈米結構的蝕刻深度,較簡單圖案的卡牌上微奈米結構的蝕刻深度較深,較複雜的卡牌上微奈米結構的蝕刻深度較淺。In order to improve the privacy of cards, that is, no matter whether the patterns on the cards are simple or complex, there is no color difference and no difference can be seen with the naked eye, the present invention creatively proposes that for the micro-nano structure on the structural surface of various cards The structure is adjusted as follows: The etching depth of the micro-nano structure is adjusted, the etching depth of the micro-nano structure on the card with the simpler pattern is deeper, and the etching depth of the micro-nano structure on the more complex card is shallower.
例如,花色圖案為1〜5的卡牌,其上的微奈米結構蝕刻深度在1.20微米〜1.5微米,花色圖案為6〜10的卡牌,其上的微奈米結構蝕刻深度在0.8微米〜1.0微米,花色圖案為11〜13,即圖案為國王K、王后Q和侍從J以及大小王(鬼牌),其上的微奈米結構蝕刻深度在0.1微米〜0.6微米。For example, a card with a suit pattern of 1 to 5 has a micro-nanostructure etched to a depth of 1.20 μm to 1.5 μm, and a card with a suit pattern of 6 to 10 has a micro-nanostructure etched to a depth of 0.8 μm. ~1.0 micron, the suit pattern is 11~13, that is, the pattern is king K, queen Q and attendant J and big and small kings (ghost cards), and the etching depth of the micro-nanostructures on it is 0.1 microns ~ 0.6 microns.
在另一個調節方案中,調節卡牌上DOE的階數,即在工藝上對於不同的卡牌採用不同次數的光刻,在卡牌上形成不同階數的微奈米結構,花色圖案為1〜5的卡牌,其上DOE為經過三次光刻得到八階的DOE,花色圖案為6〜10的卡牌,其上DOE為經過兩次光刻得到四階,圖案為11〜13以及大小王(鬼牌)的卡牌,為一次光刻得到二階微奈米結構。In another adjustment scheme, the order of DOE on the card is adjusted, that is, different times of photolithography are used for different cards in the process to form micro-nano structures of different orders on the card, and the suit pattern is 1 ~5 cards, the DOE on it is the DOE of the eighth order after three lithography, the suit pattern is 6~10, the DOE on it is the fourth order after two lithography, the pattern is 11~13 and the size The card of the king (ghost card) obtains the second-order micro-nano structure for one lithography.
光刻次數越多,卡牌塑膠膜上的霧面顏色越深。圖案簡單的卡牌,採用光刻次數較多的階數,圖案較複雜的卡牌,採用光刻次數較少的階數。這樣,就可以將一幅撲克牌圖案複雜程度不同的卡牌的霧面顏色調整的很接近而肉眼無法分辨。一個具體調節方案中,設定波長為520nm,對於簡單圖案的卡牌,第一次光刻的蝕刻深度為577.2奈米,第二次為288.6奈米,第二次為144.3奈米。The more lithography, the darker the matte color on the plastic film of the card. Cards with simple patterns use the order with more lithography times, and cards with more complex patterns use the order with fewer lithography times. In this way, it is possible to adjust the matte color of a card with different complexity of playing cards so that the color of the matte surface cannot be distinguished by the naked eye. In a specific adjustment scheme, the wavelength is set to 520 nm. For cards with simple patterns, the etching depth of the first lithography is 577.2 nm, the second is 288.6 nm, and the second is 144.3 nm.
對於圖案較複雜的卡牌,採用二次光刻,得到四階的DOE,這兩次光刻中,第一次光刻的蝕刻深度為577.2奈米,第二次為288.6奈米。For cards with more complex patterns, secondary lithography is used to obtain a fourth-order DOE. In these two lithography, the etching depth of the first lithography is 577.2 nm, and the second lithography is 288.6 nm.
對於圖案更複雜的卡牌,採用一次光刻,得到二階的DOE,這一次光刻中的蝕刻深度為577.2奈米。For cards with more complex patterns, a second-order DOE is obtained by one photolithography, and the etching depth in this photolithography is 577.2 nm.
前述僅僅是一個實施例,用以解釋和說明採用調整微奈米結構的階數的手段,不能理解為對於該手段的限定。The foregoing is only an example to explain and illustrate the means for adjusting the order of the micro-nano structures, and should not be construed as a limitation on the means.
關於各張卡牌微奈米結構的階數,還可以是,一整套卡牌的每一張的階數相同,可以是二階,也可以是四階或八階。階數越多,在照射光下顯現的圖案衍射效率得到提高。但是階數增加會提升製作成本。在又一個調解方案中,可以將上述各張卡牌上的微奈米結構的蝕刻深度和階數的調整相結合。這樣的調節可以使得用透明塑膠膜片製成的本卡牌的防窺特性更加理想。Regarding the order of the micro-nano structure of each card, it can also be that each card in a set of cards has the same order, which can be the second order, the fourth order or the eighth order. The higher the number of orders, the higher the diffraction efficiency of the pattern appearing under irradiated light. However, increasing the order will increase the production cost. In yet another adjustment solution, the adjustment of the etching depth and order of the micro-nano structures on each of the above-mentioned cards can be combined. Such adjustment can make the privacy protection of the card made of the transparent plastic film more ideal.
在又一個調節方案中,用有色的透明塑膠膜片做卡牌本體。通過用有色塑膠膜片,例如像墨鏡一樣的塑膠膜片,使得透光率降低,也可以使得各張卡牌上的微奈米結構的視覺色差趨於一致,達到完美的防窺的效果。In yet another adjustment scheme, a colored transparent plastic film is used as the card body. By using a colored plastic film, such as a plastic film like sunglasses, the light transmittance is reduced, and the visual chromatic aberration of the micro-nano structures on each card can be made consistent, so as to achieve a perfect anti-peeping effect.
在再一個調節方案中,參見圖2所示,在塑膠膜片1上的結構面上設置鍍膜層7,其可以改變卡牌的透光率,使得圖案簡單的卡牌和圖案複雜的卡牌上的微奈米結構的色差基本相同而不易分辨,以此來增強防窺性能。在本調節方案中,鍍膜材料採用透光的材料均可以。這裡,作為舉例可以是鋁,鍍膜可以採用蒸發、離子和濺射等工藝,不管是採用哪種工藝鍍膜厚度為多少,均以得到的塑膠膜片的透光率為20〜90%為準,使得區別資訊不同的卡牌在視覺上沒有差別達到通過調整塑膠膜片的透光率實現防窺。In yet another adjustment scheme, as shown in FIG. 2 , a
在實際使用中,可以將對卡牌採用調節蝕刻深度、蝕刻次數、使用有色塑膠膜片和設置光學鍍層幾個措施中的一個或幾個或全部,通過幾種措施的合理配合,就可以達到理想的防窺效果。In actual use, one or several or all of several measures of adjusting the etching depth, etching times, using colored plastic film and setting optical coating can be adopted for the card. Through the reasonable cooperation of several measures, it is possible to achieve Ideal privacy protection.
採用有色的透明塑膠膜片做卡牌本體和在卡牌上設置鍍膜層,可以使得照射光的點光源的光線更加柔和,使得成像效果更加舒適柔和。Using a colored transparent plastic film as the card body and setting a coating layer on the card can make the light of the point light source that illuminates the light softer and make the imaging effect more comfortable and soft.
對於用無色透明材料的塑膠膜片製作的卡牌,可以通過調節其上微奈米結構的蝕刻深度和光刻次數,就可以達到不錯的防窺效果。對於使用無色透明的塑膠膜片製作遊戲牌,要解決視覺色差問題,就需要採用這些手段。For cards made of plastic films made of colorless and transparent materials, a good privacy protection effect can be achieved by adjusting the etching depth and lithography times of the micro-nano structures on them. For the use of colorless and transparent plastic films to make game cards, these methods are needed to solve the problem of visual chromatic aberration.
如果可以用有色的透明塑膠膜片製作卡牌,也能較好地解決視覺色差問題,達到較好的防窺效果且其經濟性較佳。If a colored transparent plastic film can be used to make a card, the problem of visual chromatic aberration can also be better solved, a better anti-peeping effect can be achieved, and its economy is better.
對於有色透明塑膠膜片的卡牌,還可以結合鍍膜層的配合。For cards with colored and transparent plastic film, it can also be combined with the cooperation of the coating layer.
對於無色透明的塑膠膜片製作的卡牌,也可以只要使用鍍膜層的手段即可比較理想地解決視覺色差問題。這時候,一套遊戲牌中各張卡牌上的微奈米結構的蝕刻深度和階數可以是一樣的,這種方式其經濟性較佳。For cards made of colorless and transparent plastic films, the problem of visual chromatic aberration can ideally be solved by using a coating layer. At this time, the etching depth and order of the micro-nano structures on each card in a set of game cards can be the same, which is more economical.
經試驗證明,使用有色透明塑膠膜片和在塑膠膜片上設置鍍膜層而降低透光率不會影響成像效果。Tests have proved that the use of colored transparent plastic film and the setting of a coating layer on the plastic film to reduce the light transmittance will not affect the imaging effect.

本實施例提供的金陵十二釵的套牌可以成套銷售,也可以拆開銷售。The sets of Jinling Twelve Hairpins provided in this embodiment can be sold as a set or sold separately.
本發明是首次提出用DOE或HDOE在透明塑膠膜片上設計圖案製成成套的卡牌,其上的微奈米結構上記載的區別資訊,各張卡牌之間的區別特徵有連貫性及/或邏輯關係,可以製作成遊戲牌等,給這類遊戲牌增加了新的表現形式和新的品種。而進一步地,為了適應遊戲牌的防窺要求,本發明創造性地通過調節各張卡牌上的微奈米結構,例如蝕刻深度、微奈米結構的階數等,還可以通過調整塑膠膜片的透光程度而使用有色塑膠膜片和在塑膠膜片上設置鍍膜層。綜上種種措施,可以使得卡牌360°全方位防窺。The present invention is the first to propose to use DOE or HDOE to design a pattern on a transparent plastic film to make a complete set of cards. The distinguishing information recorded on the micro-nano structure on the card is consistent and the distinguishing characteristics of each card are consistent and consistent. / or logical relationship, can be made into game cards, etc., adding new expressions and new varieties to this type of game cards. Further, in order to meet the privacy protection requirements of the game cards, the present invention creatively adjusts the micro-nano structures on each card, such as the etching depth, the order of the micro-nano structures, etc., and can also adjust the plastic film. To increase the light transmittance, a colored plastic film is used and a coating layer is arranged on the plastic film. In summary, the various measures can make the card 360° all-round privacy protection.
對於例如遊戲牌,各張卡牌的圖案複雜程度相差很大,可以通過調整各張卡牌的光刻次數也就是微奈米結構的階數手段來防窺;對於一套卡牌,各張卡牌的圖案複雜程度比較接近的,可以通過調整各張卡牌上微奈米結構的蝕刻深度的手段來防窺。使用有色透明膜片或在卡牌上設置鍍膜層,調整卡牌表面視覺色差效果很好,還可以提高其美觀性。For game cards, for example, the complexity of the patterns of each card varies greatly, which can be prevented by adjusting the number of lithography of each card, that is, the order of the micro-nano structure; for a set of cards, each card The pattern complexity of the cards is relatively similar, and privacy can be prevented by adjusting the etching depth of the micro-nano structures on each card. Using a colored transparent film or setting a coating layer on the card has a good effect of adjusting the visual chromatic aberration on the surface of the card, and can also improve its aesthetics.
