図１に示すように、本発明に係る手書き用の液晶薄膜は、順次に設けられた第１ベースフィルム１００と複合層３００と第２ベースフィルム２００とを含み、前記第１ベースフィルム１００は順次に設けられた第１基材層１１０と第１電極層１２０とを含み、前記第１基材層１１０が書込み面で、前記第２ベースフィルム２００が順次に設けられた第２電極層２１０と第２基材層２２０とを含み、前記複合層３００が前記第１電極層１２０と前記第２電極層２１０の間に設けられ、前記複合層３００は、第１混合層３１０を包括し、前記第１混合層３１０の一側面が前記第１電極層１２０と貼合され、前記第１混合層３１０は、液晶分子と高分子材料とを含み、前記第１混合層３１０内の高分子材料の含有量が、前記第１電極層１２０から離れた側から前記第１電極層１２０に近い側まで徐々に減少している。 As shown in FIG. 1, the liquid crystal thin film for handwriting according to the present invention includes a first base film 100, a composite layer 300, and a second base film 200 that are sequentially provided, and the first base film 100 is sequentially formed. A first base layer 110 and a first electrode layer 120 provided on the first base layer 110, the first base layer 110 is a writing surface, and the second base film 200 is sequentially provided, The composite layer 300 is provided between the first electrode layer 120 and the second electrode layer 210, the composite layer 300 includes a first mixed layer 310, and One side surface of the first mixed layer 310 is bonded to the first electrode layer 120, and the first mixed layer 310 includes liquid crystal molecules and a polymer material, and the first mixed layer 310 includes a polymer material in the first mixed layer 310. The content is separated from the first electrode layer 120. Gradually decreases from the side to the side closer to the first electrode layer 120.
本発明の技術的解決策は、第１混合層３１０内の高分子材料の含有量が前記第１電極層１２０から離れた側から前記第１電極層１２０に近い側まで徐々に減少していることによって、第１電極層１２０に近い箇所で形成された高分子網目構造の密度が相対的に低く、第１電極層１２０に近い箇所の液晶分子の自由度を明らかにアップさせ、また第１基材層１００が書込み面となり、書き込み時、書込み面に近い箇所の更に多くの液晶分子が所要状態までにスムーズに回転でき、特定の波長の光の反射を実現することで、対応する手書き用の液晶薄膜の輝度を明らかに向上させることができる。 In the technical solution of the present invention, the content of the polymer material in the first mixed layer 310 is gradually decreased from the side away from the first electrode layer 120 to the side closer to the first electrode layer 120. As a result, the density of the polymer network formed in the portion close to the first electrode layer 120 is relatively low, and the degree of freedom of the liquid crystal molecules in the portion close to the first electrode layer 120 is clearly increased. The base material layer 100 becomes a writing surface, and at the time of writing, more liquid crystal molecules near the writing surface can be smoothly rotated to the required state, and by reflecting light of a specific wavelength, the corresponding handwriting can be used. The brightness of the liquid crystal thin film can be clearly improved.
第１基材層１１０及び第２基材層２２０は、透明なプラスチックで製造された軟質膜層とし、実施例においてＰＥＴ膜が好ましく、この場合手書き用の液晶薄膜全体の柔軟性が比較的良く、軽く書き込むと手書き用の液晶薄膜に図案を形成できる。第１導電層及び第２導電層は、ＩＴＯで製造された導電膜である。第１混合層３１０内の液晶は、コレステリック液晶で、コレステリック液晶はゼロフィールド双安定性を持ち、手書きのニーズを満たすことができ、高分子材料がモノマーを重合させることによって網目構造が形成された高分子ポリマーであり、一方では液晶分子を固定するために用いられ、別の面では手書き用の液晶薄膜を固着するためにも用いられる。 The first base material layer 110 and the second base material layer 220 are soft film layers made of a transparent plastic, and a PET film is preferable in the embodiment. In this case, the flexibility of the entire liquid crystal thin film for handwriting is relatively good. When lightly written, a design can be formed on a liquid crystal thin film for handwriting. The first conductive layer and the second conductive layer are conductive films made of ITO. The liquid crystal in the first mixed layer 310 is a cholesteric liquid crystal, and the cholesteric liquid crystal has zero field bistability, can satisfy the handwriting needs, and a polymer material forms a network structure by polymerizing monomers. On the other hand, it is used to fix liquid crystal molecules, and on the other hand, it is also used to fix a liquid crystal thin film for handwriting.
図２を参照すると、本発明の別の実施例において、第２電極層２１０と複合層３００をより一層密着するため、前記複合層３００’は前記第１混合層３１０と前記第２電極層２１０の間に位置する高分子材料層３２０を更に含む。高分子材料層３２０は、高分子バインダーを硬化させることで得られ、それは主に接着の役割を果たしている。 Referring to FIG. 2, in another embodiment of the present invention, the composite layer 300 ′ includes the first mixed layer 310 and the second electrode layer 210 in order to further adhere the second electrode layer 210 and the composite layer 300. It further includes a polymer material layer 320 positioned therebetween. The polymer material layer 320 is obtained by curing a polymer binder, which mainly plays a role of adhesion.
図３を参照すると、更に輝度を上げるため、前記複合層３００’’は、前記高分子材料層３２０と前記第２電極層２１０の間に位置する第２混合層３３０を更に含み、前記第２混合層３３０が前記高分子材料層３２０の表面に裏向けて前記第２電極層２１０と貼合され、前記第２混合層３３０は、液晶分子と高分子材料とを含み、前記第２混合層３３０内の高分子材料の含有量が前記高分子材料層３２０に近い側から前記第２電極層２１０に近い側まで徐々に減少している。このとき、第２混合層３３０の第２電極層２１０に近い箇所で形成された高分子網目構造の密度が相対的に低く、第２電極層２１０に近い箇所の液晶分子の自由度が明らかに上がり、このとき、第２電極層２１０箇所に近い液晶分子において、更に多くの液晶分子が所要状態にスムーズに回転でき、特定の波長の光に対する反射を実現することで、対応する手書き用の液晶薄膜の輝度を更に向上させることができる。高分子材料層３２０は、第１混合層３１０と第２混合層３３０を接着して、複合層３００の強度を高めるために用いられる。該高分子材料層３２０は、高純度の高分子材料で製作されることができ、該高分子材料層３２０も液晶分子と高分子材料とを含むことができ、高分子材料層３２０内の液晶分子の含有量が前記第１混合層内の液晶分子の含有量より少なく、第２混合層内の液晶分子の含有量よりも少なく、２種類の設置方式はいずれも高分子材料層３２０の接着性のニーズを満たすことができるため、選択可能な解決策とすることができる。 Referring to FIG. 3, in order to further increase the luminance, the composite layer 300 ″ further includes a second mixed layer 330 positioned between the polymer material layer 320 and the second electrode layer 210. A mixed layer 330 is bonded to the second electrode layer 210 so as to face the surface of the polymer material layer 320, and the second mixed layer 330 includes liquid crystal molecules and a polymer material. The content of the polymer material in 330 gradually decreases from the side close to the polymer material layer 320 to the side close to the second electrode layer 210. At this time, the density of the polymer network formed in the second mixed layer 330 near the second electrode layer 210 is relatively low, and the degree of freedom of the liquid crystal molecules near the second electrode layer 210 is apparent. At this time, in the liquid crystal molecules close to the second electrode layer 210, more liquid crystal molecules can be smoothly rotated to a required state, and reflection with respect to light of a specific wavelength is realized. The brightness of the thin film can be further improved. The polymer material layer 320 is used to bond the first mixed layer 310 and the second mixed layer 330 to increase the strength of the composite layer 300. The polymer material layer 320 can be made of a high-purity polymer material, and the polymer material layer 320 can also include liquid crystal molecules and a polymer material. The content of molecules is less than the content of liquid crystal molecules in the first mixed layer, and the content of liquid crystals is less than the content of liquid crystal molecules in the second mixed layer. Because it can meet the sex needs, it can be a selectable solution.
当然、更に多くの液晶層を設けることもでき、例えば該複合層３００は、順次に前記高分子材料層３２０と前記第２混合層３３０の間に設けられた第３混合層と別の高分子材料層を更に含むことができ、前記第３混合層は、液晶分子と高分子材料を含み、前記第３混合層内の高分子材料の含有量が中央に近い箇所から両表面まで徐々に増加する。更に多くの液晶層を増やすことで、更に自由度が比較的高い液晶分子の数量を増やして、手書き用の液晶薄膜の輝度を向上させることができる。 Of course, a larger number of liquid crystal layers can be provided. For example, the composite layer 300 includes a polymer layer different from the third mixed layer sequentially disposed between the polymer material layer 320 and the second mixed layer 330. The third mixed layer may include a liquid crystal molecule and a polymer material, and the content of the polymer material in the third mixed layer may gradually increase from a position near the center to both surfaces. To do. By increasing the number of liquid crystal layers, the number of liquid crystal molecules having a relatively high degree of freedom can be increased, and the luminance of the handwritten liquid crystal thin film can be improved.
上記実施例において、前記第１混合層３１０は、キラルドーパントを更に含み、キラルドーパントが液晶をコレステリック液晶に転化でき、またキラルドーパントの含有量の調整を通じてコレステリック液晶に特定の波長の光を反射せることができ、手書き用の液晶薄膜の筆跡表示を異なるカラーにさせることで、より一層良好な表示効果を奏することができる。眼精疲労を改善するため、液晶分子及びキラルドーパントの総量において２５〜３５％を占める前記キラルドーパントを設け、書いた筆跡を前記手書き用の液晶薄膜において正面から見ると緑色の筆跡、側面から見ると青色の筆跡として表示させることで、目の負担を軽減し、より一層長時間目を酷使する利用者に適し、具体的に、キラルドーパントはＳ８１１（型番）或いはＲ８１１（型番）とすることができ、液晶総量の約３０％を占めるようにする。表示のコントラスト比を高めるため、液晶分子及びキラルドーパントの総量において約６〜１５％を占める前記キラルドーパントを設けることで、書いた筆跡を前記手書き用の液晶薄膜において正面から見ると黄色の筆跡、側面から見ると緑色の筆跡として表示させ、このとき、利用者が遠距離でも手書き用の液晶薄膜の筆跡を明確に見ることができ、更に遠距離から見るという需要に適応し、具体的には、キラルドーパントをＲ１０１１とＲ８１１の混合使用とすることで、液晶総量内において約１０％占めるようにする。 In the above embodiment, the first mixed layer 310 further includes a chiral dopant, the chiral dopant can convert the liquid crystal into a cholesteric liquid crystal, and reflects light of a specific wavelength to the cholesteric liquid crystal through adjusting the content of the chiral dopant. It is possible to achieve a better display effect by changing the handwriting display of the handwritten liquid crystal thin film to a different color. In order to improve eye strain, the chiral dopant occupying 25 to 35% of the total amount of liquid crystal molecules and chiral dopant is provided, and when the handwritten handwriting is viewed from the front in the liquid crystal thin film for handwriting, the green handwriting is viewed from the side And blue handwriting, which reduces the burden on the eyes and is suitable for users who overuse the eyes for a longer time. Specifically, the chiral dopant may be S811 (model number) or R811 (model number). And about 30% of the total amount of liquid crystal. In order to increase the contrast ratio of the display, by providing the chiral dopant occupying about 6 to 15% in the total amount of liquid crystal molecules and chiral dopant, the written handwriting is yellow when viewed from the front in the handwritten liquid crystal thin film, When viewed from the side, it is displayed as a green handwriting. At this time, the user can clearly see the handwriting of the liquid crystal thin film for handwriting even at a long distance. By using a mixture of R1011 and R811 as the chiral dopant, about 10% of the total amount of liquid crystal is occupied.

S2: A liquid crystal is applied on the first base film 100 to form a first liquid crystal coating film 301.
When the cholesteric phase liquid crystal is selected and applied directly as the liquid crystal, the necessary first liquid crystal coating film 301 can be formed.
Ｓ３：第１液晶塗膜３０１上に未硬化の高分子材料を塗布して高分子材料塗膜３０２を形成する。
高分子材料は、液晶表示分野で常用されている高分子バインダーを選択し、未硬化の高分子材料が架橋して網目を形成せず、若干の流動可能なモノマーとプレポリマーとを含み、このとき、高分子材料塗膜３０２内のモノマー及びプレポリマーは、第１液晶塗膜３０１内の液晶と混合できる。
S3: A polymer material coating film 302 is formed by applying an uncured polymer material on the first liquid crystal coating film 301.
As the polymer material, a polymer binder commonly used in the field of liquid crystal display is selected, and the uncured polymer material does not form a network by cross-linking, and includes some flowable monomer and prepolymer. In some cases, the monomer and the prepolymer in the polymer material coating film 302 can be mixed with the liquid crystal in the first liquid crystal coating film 301.
Ｓ４：前記第１液晶塗膜３０１と高分子材料塗膜３０２が前記第１ベースフィルム１００と前記第２ベースフィルム２００の間に位置するように、前記第２ベースフィルム２００を前記第１ベースフィルム１００と貼合して半製品膜を形成し、
貼合するとき、第２ベースフィルム２００上の第２電極層２１０を第１ベースフィルム１００に向けて貼合する。
S4: The second base film 200 is the first base film so that the first liquid crystal coating film 301 and the polymer material coating film 302 are positioned between the first base film 100 and the second base film 200. Pasted with 100 to form a semi-finished film,
When pasting, the second electrode layer 210 on the second base film 200 is pasted toward the first base film 100.
Ｓ５：環境温度により、前記第１液晶塗膜３０１と高分子材料塗膜３０２を制御し、相互溶解性及び粘度により第１液晶塗膜３０１の成分と高分子材料塗膜３０２の成分をその界面箇所で１０秒〜３分間それぞれ相手側の膜内に拡散させて得られた相互拡散部分に第１混合塗膜を形成する。 S5: The first liquid crystal coating film 301 and the polymer material coating film 302 are controlled by the environmental temperature, and the components of the first liquid crystal coating film 301 and the components of the polymer material coating film 302 are interfaced by mutual solubility and viscosity. A first mixed coating film is formed on the interdiffusion portion obtained by diffusing into the counterpart film for 10 seconds to 3 minutes at each location.
Ｓ６：前記半製品膜を硬化させる。 S6: The semi-finished film is cured.
第１ベースフィルム１００と第２ベースフィルム２００が貼合された後、高分子材料塗膜３０２内のモノマーとプレポリマーが第１液晶塗膜３０１内に向けて拡散し、一定の時間拡散した後、第１液晶塗膜３０１の成分と高分子材料塗膜３０２の成分が相互拡散して第１混合塗膜を形成してから硬化を行うと、図１或いは図２に示す手書き用の液晶薄膜を製作できる。具体的には、拡散時間を少し長くした場合、図１に示す手書き用の液晶薄膜を製作でき、このとき、高分子材料塗膜３０２と第１液晶塗膜３０１が完全に混合するが、均一に混合せず、このときの第１混合塗膜内の高分子材料の含有量は前記第１電極層１２０から離れた側から前記第１電極層１２０に近い側まで徐々に減少し、硬化した後、第１混合塗膜が第１混合層３１０を形成し、拡散時間を少し短くした場合、図２に示す手書き用の液晶薄膜を製作でき、このとき、高分子材料塗膜３０２と第１液晶塗膜３０１が完全に混合せず、第１液晶塗膜３０１と一部の高分子材料塗膜３０２が混合して第１混合塗膜を形成し、もう一部の高分子材料塗膜３０２が第１液晶塗膜３０１と混合せず、硬化した後、第１液晶塗膜３０１と混合しない高分子材料塗膜３０２の一部が高分子材料層３２０を形成し、第１混合塗膜が第１混合層３１０を形成する。当然、拡散時間が長すぎると、高分子材料塗膜３０２と第１液晶塗膜３０１が完全に均一に混合するが、相応しい手書き用の液晶薄膜を製作できないため、本発明内において第１液晶塗膜３０１と高分子材料塗膜３０２の界面箇所における相互拡散時間を１０秒〜３分間に制御し、具体的拡散時間の選択は、拡散環境によって決定するもので、環境要因中の最も主要な影響要因は環境温度で、具体的に言うと温度が比較的高いとき、所要の拡散時間を比較的短くし、温度が比較的低いとき、所要の拡散時間を長くし、実際に操作するとき、拡散時間は状況によって時間範囲内において合理的に選択すればよい。 After the first base film 100 and the second base film 200 are bonded, the monomer and the prepolymer in the polymer material coating film 302 diffuse toward the first liquid crystal coating film 301 and diffuse for a certain period of time. When the components of the first liquid crystal coating film 301 and the polymer material coating film 302 are mutually diffused to form the first mixed coating film and then cured, the liquid crystal thin film for handwriting shown in FIG. 1 or FIG. Can be made. Specifically, when the diffusion time is slightly increased, the handwritten liquid crystal thin film shown in FIG. 1 can be manufactured. At this time, the polymer material coating film 302 and the first liquid crystal coating film 301 are completely mixed. In this case, the content of the polymer material in the first mixed coating film gradually decreased from the side away from the first electrode layer 120 to the side closer to the first electrode layer 120 and cured. Thereafter, when the first mixed coating film forms the first mixed layer 310 and the diffusion time is slightly shortened, the handwritten liquid crystal thin film shown in FIG. 2 can be manufactured. The liquid crystal coating film 301 is not completely mixed, and the first liquid crystal coating film 301 and a part of the polymer material coating film 302 are mixed to form a first mixed coating film, and the other part of the polymer material coating film 302 is mixed. Is not mixed with the first liquid crystal coating film 301 and is not mixed with the first liquid crystal coating film 301 after curing. Some of the child material coating 302 to form a polymeric material layer 320, the first mixed coating to form a first mixed layer 310. Naturally, if the diffusion time is too long, the polymer material coating film 302 and the first liquid crystal coating film 301 are completely mixed uniformly, but an appropriate handwritten liquid crystal thin film cannot be produced. The interdiffusion time at the interface between the film 301 and the polymer material coating 302 is controlled to 10 seconds to 3 minutes, and the specific diffusion time is determined by the diffusion environment, and is the most important influence among environmental factors. The factor is the ambient temperature, specifically, when the temperature is relatively high, the required diffusion time is relatively short, when the temperature is relatively low, the required diffusion time is lengthened, and when actually operating, the diffusion is The time may be selected reasonably within the time range according to the situation.
本発明に係る手書き液晶膜の製造方法は、液晶を利用して前記第１ベースフィルム１００の正面上に第１液晶塗膜３０１を形成させてから未硬化の高分子材料を利用して第１液晶塗膜３０１上に高分子材料塗膜３０２を形成し、一定の時間拡散した後、硬化を行うと本発明に係る手書き用の液晶薄膜を製作できる。該方法を通じて製作された手書き用の液晶薄膜は、第１混合層３１０を有し、第１混合層３１０内の高分子材料の含有量が前記第１電極層１２０から離れた側から前記第１電極層１２０に近い側まで徐々に減少していることによって、第１電極層１２０に近い箇所で形成された高分子網目構造の密度は相対的に低く、第１電極層１２０に近い箇所の液晶分子の自由度を明らかにアップさせ、このとき第１電極層１２０に近い箇所の液晶分子において、更に多くの液晶分子が所要状態までにスムーズに回転でき、特定の波長の光の反射を実現することで、対応する手書き用の液晶薄膜の輝度を明らかに向上させることができる。 The method for manufacturing a handwritten liquid crystal film according to the present invention uses a liquid crystal to form a first liquid crystal coating 301 on the front surface of the first base film 100 and then uses an uncured polymer material. When a polymer material coating film 302 is formed on the liquid crystal coating film 301 and is diffused for a predetermined time, and then cured, the liquid crystal thin film for handwriting according to the present invention can be manufactured. The liquid crystal thin film for handwriting manufactured through the method has a first mixed layer 310, and the content of the polymer material in the first mixed layer 310 is the first from the side away from the first electrode layer 120. By gradually decreasing to the side close to the electrode layer 120, the density of the polymer network formed in the portion close to the first electrode layer 120 is relatively low, and the liquid crystal in the portion close to the first electrode layer 120 is present. The degree of freedom of the molecules is clearly increased, and at this time, in the liquid crystal molecules near the first electrode layer 120, more liquid crystal molecules can smoothly rotate to the required state, and light of a specific wavelength can be reflected. Thus, the brightness of the corresponding liquid crystal thin film for handwriting can be clearly improved.
前記第１液晶塗膜３０１、高分子材料塗膜３０２は、順次に塗布することで形成できる。こうすると、第１液晶塗膜３０１がレベリングしてから高分子材料塗膜３０２を塗布すると、各塗膜の安定性が比較的良好となるため、構造全体の安定性も十分保証される。順次に塗布するとき、各塗布位置は、一定の間隔をあけることで、前回塗布形成した塗膜のレベリングを確保してから次の塗布へ進む。 The first liquid crystal coating film 301 and the polymer material coating film 302 can be formed by sequentially applying. In this case, when the polymer material coating film 302 is applied after the first liquid crystal coating film 301 is leveled, the stability of each coating film becomes relatively good, so that the stability of the entire structure is sufficiently ensured. When applying sequentially, each application position leaves a certain interval to ensure leveling of the coating film formed last time before proceeding to the next application.
第１液晶塗膜３０１、高分子材料塗膜３０２も一括で塗布して同時に形成することもでき、このとき、ノズルと塗布流路において異なる材料を同時に流出して塗布できるよう設計する必要があり、この場合、塗布工順を簡略化すすることで、生産効率を上げることができる。 The first liquid crystal coating film 301 and the polymer material coating film 302 can also be applied simultaneously and formed simultaneously, and at this time, it is necessary to design so that different materials can flow out and be applied simultaneously in the nozzle and the application channel. In this case, production efficiency can be increased by simplifying the coating procedure.

When step S5 is performed, the components of the second liquid crystal coating film and the polymer material The components of the coating film are also simultaneously interdiffused for 10 seconds to 3 minutes at the interface to form a second mixed coating film. The specific flow of this embodiment is as shown in FIG. The liquid crystal here is the same as the liquid crystal in step 2, and after the application is finished, the liquid crystal in the first liquid crystal coating film 301 interdiffuses with the polymer material in the polymer material coating film 302, and the second liquid crystal coating is applied. The liquid crystal in the film 303 also interdiffuses with the polymer material in the polymer material coating film 302, and after curing, forms the first mixed layer 310 in the handwritten liquid crystal thin film shown in FIG. Then, the polymer material layer 320 in the handwritten liquid crystal thin film shown in FIG. 3 is formed at 302 locations on the polymer material coating film, and the second in the liquid crystal thin film for handwriting shown in FIG. A mixed layer 330 is formed. Of course, in the present embodiment, the first liquid crystal coating film 301, the polymer material coating film 302, and the second liquid crystal coating film 303 can be formed by sequentially applying. In this way, when the first liquid crystal coating film 301 is leveled and then the polymer material coating film 302 is applied, and after the polymer material coating film 302 is leveled and the second liquid crystal coating film 303 is applied, the stability of each coating film is increased. Therefore, the stability of the entire structure is sufficiently guaranteed. Of course, the first liquid crystal coating film 301, the polymer material coating film 302, and the second liquid crystal coating film 303 can also be applied together and formed simultaneously. It can be understood with reference to FIG. 7, and at this time, it is necessary to design so that different materials can flow out and be applied simultaneously in the nozzle and the application flow path. In this case, the production efficiency is increased by simplifying the application procedure. be able to.
