背景技术Background technique
纵观当下的电子设备的设计，厂商在设计产品时往往忽略了使用者的个性化需求，例如在平板电脑、手机等移动终端领域，产品在外形和功能上常彼此雷同，即同质化现象严重。并且，用户在选购电子设备时，也不再单一的考虑电子设备的配置参数是否合格，更加会注重电子设备壳体的外观是不是符合自己的要求。对于用户来说，不同设计的手机外壳，给用户带来的直接触感是不一样的，不同颜色的外观设计搭配，带来的视觉感受也大相径庭。由此，优良的外观设计不仅能使产品得到更多用户的青睐，而且可以更好地符合体验时代消费者的心理模式，满足消费者的个性化追求。Looking at the current design of electronic equipment, manufacturers often ignore the individual needs of users when designing products. For example, in the field of mobile terminals such as tablets and mobile phones, products are often similar to each other in appearance and function, that is, homogeneity. serious. Moreover, when purchasing electronic equipment, users no longer simply consider whether the configuration parameters of the electronic equipment are qualified, but pay more attention to whether the appearance of the electronic equipment housing meets their own requirements. For users, mobile phone shells with different designs will bring different direct tactile sensations to users, and the matching of appearance designs with different colors will also bring different visual experiences. Therefore, excellent appearance design can not only make the product more favored by users, but also better conform to the psychological model of consumers in the experience era and satisfy consumers' personalized pursuit.
然而，目前的壳体及其制备方法、电子设备，仍有待改进。However, the current casing, its preparation method, and electronic equipment still need to be improved.
发明内容Contents of the invention
本发明是基于发明人对于以下事实和问题的发现和认识作出的：The present invention is based on the inventor's discovery and recognition of the following facts and problems:
发明人发现，目前的电子设备壳体(例如，移动终端壳体)普遍存在外观单一、无法满足用户个性化需求等问题。发明人发现，这主要是由于目前的移动终端外壳都是固定的颜色，并且外观也不够个性化。并且，对同一壳体用户只能得到某一种固定的外观效果，无法实现多样性的外观选择需求。如要实现多样性的外观选择，用户只能通过物理更换多个不同外观的壳体来实现，不仅过程繁琐，也会造成用户使用成本的提高。发明人意外的发现，在具有液晶封装空间的壳体中注入含有色素的液晶分子，然后利用液晶变色的原理，使液晶分子和色素在不同的电压下呈现不同的视觉效果，从而可以使壳体实现不同的外观效果，即简单快捷地实现多种外观的选择，无需更换壳体就能得到多种外观效果，满足用户更多外观选择以及个性化趋势，大大提高了产品的市场竞争力。The inventors have found that current electronic device casings (eg, mobile terminal casings) generally have problems such as single appearance and inability to meet individual needs of users.

Moreover, the user can only obtain a certain fixed appearance effect for the same housing, and cannot meet the diverse appearance selection requirements. To achieve a variety of appearance options, the user can only achieve it by physically replacing multiple housings with different appearances, which is not only a cumbersome process, but also increases the user's use cost. The inventor unexpectedly discovered that liquid crystal molecules containing pigments are injected into the housing with liquid crystal packaging space, and then the principle of liquid crystal discoloration is used to make the liquid crystal molecules and pigments present different visual effects under different voltages, thereby making the housing To achieve different appearance effects, that is, to realize the selection of various appearances simply and quickly, and to obtain a variety of appearance effects without changing the shell, satisfying users with more appearance choices and personalization trends, and greatly improving the market competitiveness of the product.

为了便于理解，下面对壳体实现上述技术效果的原理进行详细说明：For ease of understanding, the principle of the housing to achieve the above technical effects is described in detail below:
如前所述，在壳体中注入了含有色素的液晶分子，然后利用液晶变色的原理，使液晶分子和色素在不同的电压下呈现不同的视觉效果，从而可以使壳体实现不同的外观效果。具体的，在该壳体中，在液晶层中的液晶分子中加入色素，不对电极施加电压时，液晶分子与色素呈现某一状态(例如都呈现自然横放状态)，外界看到的壳体的颜色就是深色的色素颜色，然后对电极施加电压时，液晶分子按照施加电压的方案将会发生旋转，偏转的液晶分子会带动色素有规则的旋转，这时，液晶分子与色素就会呈现另一种状态(例如都呈现垂直状态)，所看到的色素面将会变小，从而颜色变浅，即在不同电压的控制下实现视觉效果上的变化，无需更换壳体就能得到多种外观效果。并且，液晶层可以具有多个间隔设置的变色器件，而多个变色器件中的色素不完全相同，具体的，参考图3，壳体包括多个变色器件300(如图3中所示出的300A～300C)，每个变色器件300的液晶层310中，分别独立的含有液晶分子20和色素10(如图3中所示出的10A～10C)，而每个变色器件300中的色素10不完全相同，由此，每个变色器件所对应的区域颜色不完全相同，即可以使壳体不同区域的颜色不完全相同，进而可以简便地实现撞色的外观效果，不仅可以在不同电压的控制下实现颜色上的变化，在相同的电压控制下也能实现不同区域的视觉效果变化。此外，每一个变色器件300独立地具有一对电极，由此，可以独立地对该变色器件300进行控制，即对各个变色器件300的控制的相互独立不受干扰的，进而，可以进一步使壳体不同区域的颜色不完全相同。总之，该壳体视觉效果变化多样，可以简单快捷地实现多种外观颜色的选择，满足用户个性化的需求，大大提高了产品的市场竞争力。As mentioned above, liquid crystal molecules containing pigments are injected into the shell, and then the principle of liquid crystal color change is used to make the liquid crystal molecules and pigments present different visual effects under different voltages, so that the shell can achieve different appearance effects . Specifically, in the casing, pigments are added to the liquid crystal molecules in the liquid crystal layer, and when no voltage is applied to the electrodes, the liquid crystal molecules and pigments assume a certain state (for example, they are both in a natural horizontal state), and the casing seen from the outside The color is the dark pigment color, and then when the voltage is applied to the electrode, the liquid crystal molecules will rotate according to the scheme of the applied voltage, and the deflected liquid crystal molecules will drive the pigment to rotate regularly. At this time, the liquid crystal molecules and the pigment will appear In another state (for example, both are in a vertical state), the pigment surface seen will become smaller, and the color will become lighter, that is, the change in visual effect can be realized under the control of different voltages, and multiple colors can be obtained without changing the shell. appearance effect. Moreover, the liquid crystal layer may have a plurality of color-changing devices arranged at intervals, and the pigments in the multiple color-changing devices are not completely the same. Specifically, referring to FIG. 3 , the housing includes a plurality of color-changing devices 300 (as shown in FIG. 3 ). 300A～300C), the liquid crystal layer 310 of each color-changing device 300 contains liquid crystal molecules 20 and pigments 10 independently (10A-10C as shown in Figure 3), and the pigment 10 in each color-changing device 300 Not exactly the same, therefore, the colors of the areas corresponding to each color-changing device are not exactly the same, that is, the colors of different areas of the shell are not exactly the same, and then the appearance effect of color contrast can be easily achieved, not only can be used under different voltages The color change can be realized under the control, and the visual effect change of different areas can also be realized under the same voltage control. In addition, each color-changing device 300 has a pair of electrodes independently, thus, the color-changing device 300 can be controlled independently, that is, the control of each color-changing device 300 is independent and uninterrupted, and further, the shell can be further made Different regions of the body are not exactly the same color. In a word, the visual effect of the casing is varied, and the choice of various appearance colors can be realized simply and quickly, which meets the individual needs of users and greatly improves the market competitiveness of the product.

In this way, the colors of the areas corresponding to different color-changing devices can be made not completely the same, and the appearance effect of contrasting colors can be easily realized. The inventors found that the housing includes a plurality of color-changing devices 300, and each color-changing device independently has a pair of electrodes that can generate an electric field and control the deflection of liquid crystal molecules, thus, the color-changing devices 300 can be independently controlled, that is, Each color-changing device 300 can be individually controlled, and furthermore, the visual appearance of the areas corresponding to the color-changing devices 300 is independent, without being interfered by other areas. The regional visual changes of the application are independent of each other, and the selection of various appearance colors can be realized simply and quickly to meet the individual needs of users and greatly improve the market competitiveness of the product.

It should be noted that the selected pigment 10 is easily miscible with the above-mentioned liquid crystal molecules 20, and after the pigment 10 is miscible with the liquid crystal molecules 20, the physical properties of the liquid crystal of the pigment 10 and its adjacent liquid crystal molecules 20 will not change. For example, after the pigment 10 is miscible with the liquid crystal molecules 20 , the optical anisotropy of the liquid crystal molecules 20 will not be changed.
如前所述，多个变色器件310中的色素10不完全相同。根据本发明的实施例，参考图3，多个变色器件310中的色素10不完全相同，具体的，可以是各个变色器件300所对应的液晶层310中，在液晶分子20中加入的色素10的化学组成不同，例如，变色器件300A中含有的色素10A与变色器件300B中含有的色素10B的化学组成不同；或者，可以是各个变色器件300所对应的液晶层310中，在液晶分子20中加入色素10的比例不同，例如，变色器件300A中加入的色素10A与变色器件300B中加入的色素10B的比例不同。由此，可以使壳体中不同变色器件300所对应的区域的颜色不完全相同，即可以使壳体不同区域的颜色不完全相同，实现撞色的外观效果，壳体外观颜色选择更加多样化，满足用户个性化的需求。根据本发明的实施例，多个变色器件300中的色素10不完全相同也可以是多个变色器件300中的色素的颜色不完全相同。由此，可以使壳体不同区域的颜色不完全相同，进而可以简便地实现撞色的外观效果，不仅可以在不同电压的控制下实现视觉效果上的变化，在相同的电压控制下也能实现不同区域的颜色变化，并且，可以实现各个变色器件的单独控制，不受其他变色器件的干扰，实现不同区域的颜色独立变化，壳体外观颜色选择更加多样化，满足用户个性化的需求。As mentioned above, the pigments 10 in the plurality of color changing devices 310 are not all the same. According to an embodiment of the present invention, with reference to FIG. 3 , the pigments 10 in a plurality of color-changing devices 310 are not completely the same, specifically, the pigments 10 added to the liquid crystal molecules 20 in the liquid crystal layer 310 corresponding to each color-changing device 300 For example, the chemical composition of the pigment 10A contained in the color-changing device 300A is different from that of the pigment 10B contained in the color-changing device 300B; or, in the liquid crystal layer 310 corresponding to each color-changing device 300, in the liquid crystal molecules 20 The ratio of the pigment 10 added is different, for example, the ratio of the pigment 10A added in the color-changing device 300A is different from the ratio of the pigment 10B added in the color-changing device 300B. Thus, the colors of the regions corresponding to different color-changing devices 300 in the casing can be made not completely the same, that is, the colors of different regions of the casing can be made not completely the same, so that the appearance effect of contrasting colors can be achieved, and the choice of the appearance color of the casing can be more diversified , to meet the individual needs of users. According to an embodiment of the present invention, if the pigments 10 in the multiple color changing devices 300 are not completely the same, it may also mean that the colors of the pigments in the multiple color changing devices 300 are not completely the same. In this way, the colors of different areas of the shell can be made different, and the appearance effect of contrasting colors can be easily realized. Not only can the change of visual effect be realized under the control of different voltages, but also can be realized under the control of the same voltage. The color changes in different areas, and the individual control of each color-changing device can be realized without the interference of other color-changing devices, and the color of different areas can be changed independently. The color selection of the shell appearance is more diversified to meet the individual needs of users.
根据本发明的实施例，参考图4，壳体进一步包括界定结构400，该界定结构400用于将多个变色器件300间隔开。由此，可以使壳体简便的形成多个区域(每个变色器件300对应一个区域)，并且各个区域中的色素不完全相同时，可以使不同区域的颜色不完全相同，进而可以简便地实现撞色的外观效果。并且，每个区域可以单独控制，各区域之间不会相互干扰，颜色以及视觉效果可以独立地控制，进一步提升壳体的性能。根据本发明的实施例，该界定结构400的形成材料不受特别限制，只需满足形成多个间隔的多个变色器件300即可。例如，当第一电极320设置在第一衬底100与液晶层310之间，第二电极330设置在第二衬底200与液晶层310之间时，可以是在第一电极320或第二电极330上的预定位置涂覆胶水并干燥而形成上述界定结构400。According to an embodiment of the present invention, referring to FIG. 4 , the housing further includes a limiting structure 400 for separating a plurality of color changing devices 300 . Thus, the shell can be easily formed into multiple regions (each color-changing device 300 corresponds to one region), and when the pigments in each region are not completely the same, the colors of different regions can be made not completely the same, and then it can be easily realized. Contrasting look. Moreover, each area can be controlled independently, and the areas will not interfere with each other, and the color and visual effects can be controlled independently, further improving the performance of the housing. According to the embodiment of the present invention, the forming material of the defining structure 400 is not particularly limited, as long as it meets the requirement of forming multiple color-changing devices 300 at multiple intervals. For example, when the first electrode 320 is disposed between the first substrate 100 and the liquid crystal layer 310, and the second electrode 330 is disposed between the second substrate 200 and the liquid crystal layer 310, it may be between the first electrode 320 or the second Glue is coated on a predetermined position on the electrode 330 and dried to form the above-mentioned defining structure 400 .
下面以多个变色器件中的一个变色器件为例，其中，变色器件300中的液晶层310(含有液晶分子20和色素10)设置在第一电极320以及第二电极330之间，对变色器件300实现变色的原理进行详细说明：Take a color-changing device among a plurality of color-changing devices as an example below, wherein, the liquid crystal layer 310 (containing liquid crystal molecules 20 and pigment 10) in the color-changing device 300 is arranged between the first electrode 320 and the second electrode 330, for the color-changing device The principle of 300 color change is explained in detail:
在本发明的一些实施例，第一电极320和第二电极330之间形成电场和未形成电场时，液晶层中的液晶分子偏转状态不同，从而可以导致壳体在上述两种状态下光的透过率发生改变。而色素分子依靠吸收光线中特定波长的光，反应出被吸收的光的互补色的原色，因此壳体整体透过率有改变，可以实现壳体整体的视觉效果(颜色)的变化。In some embodiments of the present invention, when an electric field is formed between the first electrode 320 and the second electrode 330 and when no electric field is formed, the deflection states of the liquid crystal molecules in the liquid crystal layer are different, which may cause the housing to be in the above two states. The transmittance changes. The pigment molecules rely on the absorption of light of a specific wavelength in the light, and reflect the primary color of the complementary color of the absorbed light. Therefore, the overall transmittance of the shell changes, and the overall visual effect (color) of the shell can be changed.
根据本发明的一些具体实施例，以液晶分子20具有正的介电常数各向异性为例进行说明：变色器件300中的液晶层310处于关态时，液晶层310的透光率可以为10～20％，当对第一电极320和第二电极330施加电压时，即变色器件300中的液晶层310处于开态时，液晶分子20按照所施加的电压发生旋转，这时，偏转的液晶分子20会有规则的旋转，进而变色器件300中的液晶层310处于开态时，液晶层310的透光率较高，如可以为20～40％。也就是说，液晶层310的透光率由10～20％增大为20～40％。由此，可以通过施加电压可令壳体整体具有更加明亮的视觉效果。或者，根据本发明的另一些实施例，液晶分子20也可以具有负的介电常数各向异性。此时，液晶层310处于关态时(不施加电压)，壳体具有较高的透光率，如可以为20～40％。液晶层310处于开态时，壳体可以具有较低的透光率，如可以为10～20％。由此，也可以通过施加电压，调控壳体的外观状态。According to some specific embodiments of the present invention, the liquid crystal molecules 20 have positive dielectric constant anisotropy as an example for illustration: when the liquid crystal layer 310 in the color-changing device 300 is in the off state, the light transmittance of the liquid crystal layer 310 can be 10 ~20%, when a voltage is applied to the first electrode 320 and the second electrode 330, that is, when the liquid crystal layer 310 in the color-changing device 300 is in an open state, the liquid crystal molecules 20 rotate according to the applied voltage, and at this time, the deflected liquid crystal The molecules 20 will rotate regularly, and when the liquid crystal layer 310 in the color-changing device 300 is in the on state, the light transmittance of the liquid crystal layer 310 is relatively high, for example, it can be 20-40%. That is to say, the light transmittance of the liquid crystal layer 310 increases from 10-20% to 20-40%. Therefore, by applying a voltage, the whole housing can have a brighter visual effect. Alternatively, according to other embodiments of the present invention, the liquid crystal molecules 20 may also have negative dielectric constant anisotropy. At this time, when the liquid crystal layer 310 is in the off state (no voltage is applied), the housing has a relatively high light transmittance, for example, 20-40%. When the liquid crystal layer 310 is in an on state, the casing may have a relatively low light transmittance, for example, 10-20%. Thus, the appearance state of the casing can also be regulated by applying a voltage.
根据本发明的另一些实施例，掺杂的色素10可以和液晶分子20具有类似的结构，如液晶分子20和色素10的形状均为棒状。参考图5，变色器件300中的液晶层310处于关态时(不施加电压)，液晶分子20和色素10都呈现水平横放状态，即液晶分子20和色素10的长轴方向均平行于水平面，外界看到的壳体的颜色就是色素10所呈现的颜色，此时，液晶层310的透光率为10～20％。参考图6，当变色器件300中的液晶层310处于开态时(施加电压)，液晶分子20会按照所施加的电压将会发生旋转，偏转的液晶分子20会带动色素10有规则的旋转，即色素10本身在电场作用下不会独立地发生偏转，需要在液晶分子20的带动下进行偏转，液晶分子20和色素10都呈现垂直状态，即液晶分子20和色素10的长轴方向均垂直于水平面，此时，外界所看到的色素10的面将会变小，透光率也会相应的变大，液晶层310的透光率为20～40％，从而外界所看到的壳体的颜色变浅，即在不同电压的控制下实现颜色深浅的改变，达到视觉效果上的变化。由此，可以通过电压的控制，对变色器件300中的液晶层310的透光率进行调节，最终简便的实现壳体视觉效果的变化多样，实现多种外观的选择，无需更换壳体就能得到多种外观效果，满足用户个性化的需求，大大提高了产品的市场竞争力。According to other embodiments of the present invention, the doped pigment 10 may have a similar structure to the liquid crystal molecules 20, for example, the shapes of the liquid crystal molecules 20 and the pigment 10 are rod-like. Referring to FIG. 5 , when the liquid crystal layer 310 in the color-changing device 300 is in the off state (no voltage is applied), the liquid crystal molecules 20 and the pigment 10 are placed horizontally, that is, the long axes of the liquid crystal molecules 20 and the pigment 10 are parallel to the horizontal plane. , the color of the casing seen from the outside is the color presented by the pigment 10 , and at this time, the light transmittance of the liquid crystal layer 310 is 10-20%. Referring to FIG. 6 , when the liquid crystal layer 310 in the color-changing device 300 is in an open state (voltage is applied), the liquid crystal molecules 20 will rotate according to the applied voltage, and the deflected liquid crystal molecules 20 will drive the pigment 10 to rotate regularly. That is, the pigment 10 itself will not deflect independently under the action of the electric field, but needs to be deflected under the drive of the liquid crystal molecules 20, and the liquid crystal molecules 20 and the pigment 10 are in a vertical state, that is, the long axes of the liquid crystal molecules 20 and the pigment 10 are both vertical At this time, the surface of the pigment 10 seen by the outside world will become smaller, and the light transmittance will also increase accordingly. The light transmittance of the liquid crystal layer 310 is 20-40%, so that the shell seen by the outside world The color of the body becomes lighter, that is, the color depth is changed under the control of different voltages, and the visual effect is changed. Thus, the light transmittance of the liquid crystal layer 310 in the color-changing device 300 can be adjusted through voltage control, and finally, various changes in the visual effect of the housing can be easily realized, and a variety of appearance options can be realized without changing the housing. A variety of appearance effects can be obtained to meet the individual needs of users and greatly improve the market competitiveness of products.
根据本发明的另一些实施例，液晶分子20和色素10也可以在关态下都呈现垂直状态，在开态下呈现水平状态。即关态下液晶分子20和色素10的长轴方向均垂直于水平面(衬底所在平面)，外界所看到的色素10的面较小，从而外界所看到的壳体的颜色较浅亮度较大。开态下外界可见的色素10的面积较大，从而外界所看到的壳体的颜色较深亮度较小。According to some other embodiments of the present invention, both the liquid crystal molecules 20 and the pigment 10 may be in a vertical state in the off state, and in a horizontal state in the on state. That is to say, in the OFF state, the long axis directions of the liquid crystal molecules 20 and the pigment 10 are both perpendicular to the horizontal plane (the plane where the substrate is located), and the surface of the pigment 10 seen by the outside world is relatively small, so that the color of the shell seen by the outside world is lighter. larger. In the open state, the pigment 10 visible to the outside has a relatively large area, so that the casing seen by the outside has a darker color and less brightness.
需要说明的是，液晶分子20和色素10都呈现上述水平横放状态时，不仅包括液晶分子20和色素10完全地平行于水平面的情况，也包括液晶分子20和色素10相对于水平面稍微倾斜的情况。液晶分子20和色素10都呈现上述垂直状态时，不仅包括液晶分子20和色素10完全地平行于水平面的法线的情况，也包括液晶分子20和色素10相对于水平面的法线稍微倾斜的情况。It should be noted that when both the liquid crystal molecules 20 and the pigments 10 are placed horizontally, it includes not only the situation where the liquid crystal molecules 20 and the pigments 10 are completely parallel to the horizontal plane, but also the situation where the liquid crystal molecules 20 and the pigments 10 are slightly inclined relative to the horizontal plane. Happening. When the liquid crystal molecules 20 and the pigment 10 both exhibit the above-mentioned vertical state, it includes not only the situation that the liquid crystal molecules 20 and the pigment 10 are completely parallel to the normal line of the horizontal plane, but also the situation that the liquid crystal molecules 20 and the pigment 10 are slightly inclined relative to the normal line of the horizontal plane. .
根据本发明的实施例，由于液晶层具有多个变色器件300，在相同的电压控制下，由于各个变色器件的液晶层中的色素不完全相同，也能实现不同液晶层的颜色不同，使壳体达到撞色的外观效果，进一步实现壳体视觉效果的变化多样，实现多种外观的选择。另外，每个变色器件300都独立的具有可以产生电场并使液晶分子20偏转的电极对，由此，可以独立地对变色器件300进行控制，即可以各个变色器件300进行单独控制，进而，可以变色器件300多对应的区域，其外观视觉变化是独立的，不受其他区域的干扰。According to the embodiment of the present invention, since the liquid crystal layer has a plurality of color-changing devices 300, under the same voltage control, since the pigments in the liquid crystal layers of each color-changing device are not completely the same, different colors of different liquid crystal layers can also be realized, making the shell The body achieves the appearance effect of contrasting colors, further realizes the variety of visual effects of the shell, and realizes the choice of various appearances. In addition, each color-changing device 300 independently has an electrode pair that can generate an electric field and deflect the liquid crystal molecules 20, thus, the color-changing device 300 can be controlled independently, that is, each color-changing device 300 can be controlled separately, and further, it can The areas corresponding to the color-changing device 300 have independent visual changes in appearance and are not interfered by other areas.

Thus, the connection wire can be made into a structure integrated with the first electrode or the second electrode, which simplifies the production process. In addition, each color-changing device is independently connected to the control unit, so that the control unit can independently control the color-changing devices, that is, each color-changing device can be controlled individually, and further, the appearance of the corresponding area of the color-changing device can be visually changed It is independent and free from interference from other areas. Furthermore, the visual effects of the shell are varied, and the visual changes of the areas used by different color-changing devices are independent of each other.

Therefore, the backlight source can be arranged on the side of the casing away from the user in practical applications.
反射膜可以反射光线，由此，也可以通过在壳体的内侧(实际应用时远离用户的一侧)设置反射膜，将光线通过反射由壳体的外侧射出，可以提升该壳体的亮度，使色素展现出更佳的颜色，进一步提升壳体的视觉效果。The reflective film can reflect light. Therefore, the reflective film can also be provided on the inner side of the housing (the side away from the user in actual application), and the light can be emitted from the outer side of the housing through reflection, which can improve the brightness of the housing. Make the pigment show a better color, and further enhance the visual effect of the shell.
根据本发明的实施例，该壳体还可以进一步包括诸如偏光片、导光板(用于对背光源进行匀光)等结构。由此，可以进一步提高该壳体的外观效果。According to an embodiment of the present invention, the casing may further include structures such as a polarizer, a light guide plate (used to uniformly light the backlight source), and the like. Thus, the appearance effect of the housing can be further improved.
