一种膜片、终端壳体以及终端
本申请要求在2018年12月25日提交中国国家知识产权局、申请号为201811593973.5、发明名称为“一种膜片、终端壳体以及终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及终端领域，尤其涉及一种膜片、终端壳体以及终端。
背景技术
当前终端的外观材质大多采用玻璃材质。玻璃材质的工艺处理方式对外观效果的影响非常大，进而对终端的竞争力和差异化至关重要。随着玻璃材质在终端中的应用，终端厂商都在寻求玻璃材质上工艺的突破，玻璃材质上的工艺技术已同质化严重：从丝印，喷涂，到玻璃镀膜，膜具转印(Glass direct molding，GDM)，再到聚对苯二甲酸乙二醇酯(polyethylene terephthalate，PET)膜片纹理等。为了提升终端的外观质量，提升终端外观竞争力，避免同质化，急需创新的颜色材料工艺(color material finish，CMF)效果解决方案。
发明内容
本申请实施例提供一种膜片、终端壳体以及终端，用以丰富膜片上的装饰工艺。
为了达到上述目的，本申请实施例采用如下技术方案：
第一方面，本申请实施例提供一种膜片，包括：第一膜片，以及第二膜片。其中，第一膜片的下表面具有渐消区，第二膜片的下表面具有纹理层，以及设置在纹理层下方的不透光层，第一膜片的下表面和第二膜片的上表面贴合；渐消区包括透明区域以及位于透明区域外的半透光区域；当光线入射到第二膜片时，纹理层上的纹理图案通过透明区域被显示。
本申请实施例提供一种膜片，由于第二膜片的下表面具有纹理层，该纹理层上具有纹理图案，可以丰富第二膜片的装饰工艺效果。由于纹理层上覆盖不透光层，当光线入射到第二膜片时，这样不透光层可以对环境光线进行反射，从而使得纹理图案被显示。此外，第一膜片的下表面具有渐消区，这样纹理层上的纹理图案通过渐消区的透明区域被显示。由于纹理层上的纹理图案仅在透明区域被显示，在半透光区域不显示或者少量显示。这样与单一颜色或者单一质感效果的工艺相比，本申请实施例提供的膜片可以使得纹理图案更加丰富和炫亮，且具有更强的立体感。当该膜片与透明基板结合使用形成终端壳体时，利用透明基板的通透特性，通过膜片上的丰富装饰工艺效果，可以丰富终端壳体的颜色和光影层次。从而使得应用该终端壳体的终端的光影和颜色效果更丰富，更炫亮，更迷人。
在一种可选的实现方式中，沿第一膜片的下表面的边缘指向第一膜片的下表面的中心方向，半透光区域的透光率增高。这样可以使得纹理图案沿着第一膜片的下表面的边缘指向第一膜片的下表面的中心方向，从半透光区域逐渐被显示出来，从而呈现出一种动态显示的效果。
本申请实施例的渐消区包括：位于第一膜片的下表面的中心的透明区域，设置在透明区域四周的第一区域。沿第一区域的边缘指向第一膜片的下表面的中心的方向，第一 区域的颜色逐渐降低。这样便于纹理层上的纹理图案通过透明区域显示出来。
在一种可选的实现方式中，沿第一膜片的下表面的边缘指向第一膜片的下表面的中心方向，半透光区域的透光率从第一阈值增高至第二阈值，第二阈值与透明区域的透光率一致。
在一种可选的实现方式中，半透光区域为覆盖在第一膜片的下表面的半透光涂层。例如，半透光涂层的颜色为黑色。
在一种可选的实现方式中，透明区域为覆盖在第一膜片的下表面的透明涂层。
在一种可选的实现方式中，第二阈值为90％-100％。第一阈值为0-10％。
在一种可选的实现方式中，纹理层上的纹理图案的位置与透明区域的位置相对。这样可以仅在透明区域显示纹理图案，避免因为大面积在纹理层上印制纹理图案引起的资源浪费。
在一种可选的实现方式中，半透光区域包括对称设置在透明区域左右两侧的第一区域，以及对称设置在透明区域上下两侧的第二区域。这样在对称区域纹理图案被显示的状态将一致。
在一种可选的实现方式中，纹理图案为微米级别纹理图案或纳米级别纹理图案。
在一种可选的实现方式中，纹理图案为按照预设角度排列的柱形透镜条纹。这样可以使得膜片具有动态景深及闪亮的效果。
在一种可选的实现方式中，纹理图案的纹理深度为6-12微米，纹理图案的周期为44微米-64微米。
在一种可选的实现方式中，不透光层包括：覆盖在纹理层上的镀膜层，以及覆盖在镀膜层上的油墨层。通过设置不透光层可以防止光线穿透纹理层，此外还可以使得纹理图案更加绚丽。
在一种可选的实现方式中，纹理层上具有双周期V型光影纹理图案。
在一种可选的实现方式中，在第一膜片的下表面和第二膜片的上表面之间设置有光学胶层，第一膜片的下表面和第二膜片的上表面通过光学胶层粘结。
第二方面，本申请实施例提供一种终端壳体，包括：透明基板，以及贴合在透明基板上的如上述第一方面描述的膜片。
在一种可选的实现方式中，该透明基板的一面与膜片包括的第一膜片的上表面贴合。
第三方面，本申请实施例提供一种终端包括：如第二方面描述的终端壳体。

具体实施方式
为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、 “第二”等字样对功能和作用基本相同的相同项或相似项进行区分。例如，第一膜片和第二膜片仅仅是为了区分不同的膜片，并不对其先后顺序进行限定。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本申请的描述中，需要理解的是，术语“长度”、“宽度”、“左”、“右”、“上”、“下”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
如图1所示，图1示出了本申请实施例提供的一种膜片的结构示意图，该膜片包括：第一膜片10，以及第二膜片20。
其中，第一膜片10的下表面具有渐消区50，第二膜片20的下表面具有纹理层30，以及设置在所述纹理层30下方的不透光层40。第一膜片10的下表面和第二膜片20的上表面贴合。
如图2所示，渐消区50包括透明区域501以及位于透明区域外的半透光区域502(例如，图2中的阴影部分)。当光线入射到第二膜片20时，纹理层30上的纹理图案通过透明区域501被显示。
本申请实施例中的第一膜片10具有上表面和与上表面相对的下表面。第一膜片10的上表面可用于贴合在透明基板上。
本申请实施例中的第二膜片20具有上表面和与上表面相对的下表面。第二膜片20的上表面用于与第一膜片10的下表面贴合。第二膜片20的下表面用于印制纹理图案。
本申请实施例中纹理层30下方指与纹理层30的上方相对的一面。其中，纹理层30的上方和第二膜片20的下表面贴合。
本申请实施例提供一种膜片，由于第二膜片的下表面具有纹理层，该纹理层上具有纹理图案，可以丰富第二膜片的装饰工艺效果。由于纹理层上覆盖不透光层，当光线入射到第二膜片时，这样不透光层可以对环境光线进行反射，从而使得纹理图案被显示。此外，第一膜片的下表面具有渐消区，这样纹理层上的纹理图案通过透明区域被显示。由于纹理层上的纹理图案仅在透明区域被显示，在半透光区域不显示或者少量显示。这样与单一颜色或者单一质感效果的工艺相比，本申请实施例提供的膜片可以使得纹理图案更加丰富和炫亮。当该膜片与透明基板结合使用形成终端壳体时，利用透明基板的通透特性，通过膜片上的丰富装饰工艺效果，可以丰富终端壳体的颜色和光影层次。从而使得应用该终端壳体的终端的光影和颜色效果更丰富，更炫亮，更迷人。
示例性的，本申请实施例中第一膜片10和第二膜片20的厚度可以为0.06-0.10mm。例如，第一膜片10和第二膜片20的厚度可以为0.08mm。
应理解，本申请实施例中可以采用渐变印刷工艺在第一膜片10的下表面形成具有颜色渐变的渐消区50。
在一种可选的实现方式中，本申请实施例中纹理图案可以通过以下方式印制在纹理层上：采用纹理转印工艺在第二膜片20的下表面形成纹理图案。
其中，纹理转印工艺是将表面有纳米级或者微米级微细凹凸结构的纹理模具压到树脂等材料上，使其微细结构转写到另外的基材上的微细加工技术。
应理解，纹理模具的粒度还可以为纳米级或者微米级以外的其他级别。
具体的，纹理转印工艺包括：在第二膜片20上均匀覆盖UV胶水，然后采用纳米级纹理模具或者微米级纹理模具将UV胶水压出纳米级别或微米级别的纹理图案。从而将纹理图案转移到第二膜片20上。
本申请实施例对纹理图案的内容不作限定，在实际过程中，该纹理图案可以根据需要设置。例如，当需要在第二膜片20的下表面上印制纹理图案时，可以采用与该纹理图案匹配的纳米级纹理模具，以在第二膜片20的下表面上印制出纳米级纹理模具对应的纹理图案。
示例性的，纹理图案可以为字母、字符或者汉字等。例如，纹理图案可以为单V型、双V型、单W型、双W型、单Z型、双Z型等。应理解，此处仅是示例性的列出了纹理图案可能出现的几种示例。
示例性的，本申请实施例中的膜片可以是由透明材料形成的。例如，本申请实施例中涉及到的第一膜片10和第二膜片20可以为聚对苯二甲酸乙二醇酯(polyethyleneterephthalate，PET)膜片或者为聚碳酸酯(Polycarbonate，PC)膜片。
本申请实施例中的第一膜片10或第二膜片20的尺寸和形状可以基于该膜片最终贴合的透明基板的尺寸和形状设计。
在一种可选的实施例中，为了使得纹理图案沿第一膜片的下表面的边缘指向第一膜片的下表面的中心方向逐渐被显示，增加纹理图案的动态显示效果。本申请实施例中沿第一膜片10的下表面的边缘指向第一膜片10的下表面的中心方向，半透光区域502的透光率增高。应理解，当沿第一膜片10的下表面的边缘指向第一膜片10的下表面的中心方向，半透光区域502的透光率增高时，与半透光区域502相对位置设置的纹理图案逐渐被显示。半透光区域502中透光率高的区域显示的纹理图案的清晰度高于半透光区域502中透光率低的区域显示的纹理图案的清晰度。
应理解，该半透光区域502的透光率逐渐增高。
在一种可选的实施例中，为了使得半透光区域和透明区域的衔接自然，本申请实施例中沿所述第一膜片的下表面的边缘指向所述第一膜片的下表面的中心方向，半透光区域的透光率从第一阈值增高至第二阈值，第二阈值与透明区域的透光率一致。
本申请实施例中的第二阈值与透明区域的透光率一致可以指：第二阈值与透明区域的透光率完全相同，也可以指第二阈值与透明区域的透光率在允许误差范围内。
本申请实施例对第二阈值和第一阈值的具体数值不作限定。应理解，只要使得纹理图案可以通过透明区域501被显示时，该透明区域501的透光率即可作为第二阈值。示例性的，本申请实施例中的第二阈值可以为90％-100％。应理解，只要使得纹理图案在半透光区域不显示或者少量显示时，该半透光区域502的透光率即可作为第一阈值。示例性的，第一阈值可以为0-10％。
示例性的，本申请实施例中的半透光区域502可以为设置在所述第一膜片10的下表面的半透光涂层。本申请实施例中的半透光涂层不透光，即与该半透光涂层相对位置处的纹理图案不显示。或者本申请实施例中的半透光涂层可以使得少量光通过，以使得位于该与该半透光涂层相对位置处的纹理图案隐约显示。
本申请实施例对半透光涂层的颜色不作限定。例如，半透光涂层的颜色可以为不透 光的颜色，例如黑色。
本申请实施例中透明区域501可以为设置在第一膜片10的下表面的透明涂层。本申请实施例中的透明涂层透光，即与该透明涂层相对位置处的纹理图案显示。
应理解，在实际过程中，本申请实施例中，从半透光涂层到透明图层的颜色变化为从深色到浅色逐渐消失。
示例性的，如图3所示，图3示出了该渐消区设计效果图。由图3可以看出半透光区域502的颜色沿着半透光区域502边缘指向透明区域501的方向逐渐降低，直至在靠近透明区域501边缘时，半透光区域502的颜色逐渐变为透明色。
在一种可选的实现方式中，如图2或如图4所示，半透光区域502可以包围透明区域501。
举例说明，位于透明区域501的左侧的半透光区域502的透光率，沿第一膜片10的下表面的左侧边缘指向第一膜片10的下表面的中心方向从第一阈值增高至第二阈值。位于透明区域501的右侧的半透光区域502，沿第一膜片10的下表面的右侧边缘指向第一膜片10的下表面的中心方向，半透光区域502的透光率从第一阈值增高至第二阈值。位于透明区域501的上方半透光区域502，沿第一膜片10的下表面的上方边缘指向第一膜片10的下表面的中心方向，半透光区域502的透光率从第一阈值增高至第二阈值。半透光区域502位于透明区域501的下方时，沿第一膜片10的下表面的下方边缘指向第一膜片10的下表面的中心方向，半透光区域502的透光率从第一阈值增高至第二阈值。
在一种可选的实现方式中，本申请实施例中纹理层30上的纹理图案的位置与透明区域501的位置相对。这样在纹理层30上印制纹理图案时，可以在与透明区域501的位置相对印制纹理图案。避免了纹理转印时的油墨浪费。
在一种可选的实现方式中，本申请实施例的半透光区域502包括对称设置在透明区域501左右两侧的第一区域，以及对称设置在透明区域501上下两侧的第二区域。
应理解，对称设置在透明区域501左右两侧的第一区域的透光率的变化规律一致。对称设置在透明区域501上下两侧的第二区域的透光率的变化规律一致。
本申请实施例中对透明区域501的具体形状不作限定，透明区域501的具体形状可以根据需要设置在第一膜片10的下表面。
示例性的，透明区域501的形状可以为如图2所示的矩形，也可以为图4或图5所示的圆形。当然，透明区域501的形状也可以为椭圆形或者其他不规则形状，本申请实施例对此不作限定。
应理解，由于半透光区域502和透明区域501均位于第一膜片10的下表面，因此，半透光区域502的形状可以由透明区域501的形状确定。
在另一种可选的实现方式中，半透光区域502可以包括对称设置在透明区域501左右两侧的第一区域。或者在又一种可选的实现方式中，半透光区域502可以包括对称设置在透明区域501上方和下方的第二区域。本申请实施例对此不作限定。
在一种可选的实现方式中，纹理图案为微米级别纹理图案或纳米级别纹理图案。
当然可以理解的是，纹理图案的精度级别可以根据需要进行设置。
以透明区域501的形状可以为矩形，以纹理图案为V型为例。如图6所示，图6所示示例出了纹理图案的显示效果。图6中以半透光区域502不显示纹理图案为例。如图7所示，当半透光区域502的透光率逐渐增加时，如图7所示，可以看出沿半透光区域502指向透明区域501的方向，纹理图案逐渐显示出来，且在透明区域501所显示的纹 理图案的清晰度高于半透光区域502所显示的纹理图案的清晰度。
在一种可选的实现方式中，如图8所示，纹理图案为按照预设角度排列的柱形透镜条纹。
本申请实施例对预设角度可以基于设计纹理图案时，晶格排列而定，本申请实施例对此不作限定。
应理解，本申请实施例中的纹理层30上的纹理图案与透明区域501相对设置。这样便于纹理层30上的纹理图案通过透明区域501显示出来。
在一种可选的实施例中，纹理层30上具有柱形透镜条纹，柱形透镜条纹按照预设角度排列。
如图8所示，在一种可选的实现方式中，纹理层30上具有多周期V型光影纹理图案。
本申请实施例中的纹理图案可以按照预设周期，周期性的设置在纹理层30上。
示例性的，纹理层30上的纹理深度为6微米-12微米，周期为44微米-64微米。例如，纹理层30上的纹理深度为8微米，周期为44微米。
应理解，纹理层30上的纹理深度和周期可以根据需要设置，本申请实施例对此不作限定。
在一种可选的实施例中，如图1所示，本申请实施例中的不透光层40包括：设置在纹理层30下方的镀膜层401，以及设置在镀膜层401下方的油墨层402。
其中，镀膜层401下方为与镀膜层401上方相对的一面。镀膜层401上方贴合纹理层30下方。
具体的，可以采用光学镀膜工艺在纹理层30上进行光学镀膜，以使得纹理层30上覆盖镀膜层401。采用丝网印刷工艺在镀膜层401上丝印油墨层402。镀膜层401用于使得纹理层30上的纹理图案具有绚丽的金属光泽。该油墨层402用于防止光线穿透，此外还可以提高第二膜片20上的纹理图案达到理想效果。
示例性的，光学镀膜材质可以为金属氧化物。例如，氟化镁、二氧化钛、或氧化锆等。本申请实施例对此不作限定。
本申请实施例对丝印在镀膜层401上的油墨层402的厚度不作限定，可以根据实际需要设置。
在一种可选的实施例中，如图1所示，在第一膜片10的下表面和所述第二膜片20的上表面之间设置有透明粘结层60，第一膜片10的下表面和所述第二膜片20的上表面通过所述透明粘结层60粘结。
应理解，本申请实施例中的透明粘结层60的形状和尺寸与上述第一膜片10和第二膜片20的形状和尺寸匹配。
示例性的，透明粘结层60为光学胶(Optically Clear Adhesive，OCA)层。
在一种可选的实施例中，由于该膜片通常可以贴合在透明基板上以形成终端壳体。而终端壳体上通常可以具有一个或者多个第一通孔，用于与终端内部的电子元件相对设置。因此，该膜片上也可以具有一个或者多个第二通孔，该一个或者多个第二通孔与终端壳体上通常具有的一个或者多个第一通孔一一对应。
在另一种实施例中，本申请实施例提供一种终端壳体，包括：透明基板，以及贴合在透明基板上的如上述实施例描述的膜片。例如，一种可实现的终端壳体可如图9所示。
示例性的，该膜片通过OCA层贴合在透明基板上。
其中，本发明实施例中的透明基板的材质可以为玻璃材质，或者为PET，或者为树 脂，或者为陶瓷，本申请实施例对此不作限定。应理解，本申请实施例中的终端壳体可以用作终端的后盖。
在又一种实施例中，本申请实施例一种终端，该终端包括：上述实施例中描述的终端壳体。
应理解，该终端包括第一壳体、设置于第一壳体内的印制电路板(Printed circuit board，PCB)以及本发明实施例提供的终端壳体。其中，终端壳体与第一壳体连接，在第一壳体内设置有与PCB板连接的摄像头组件。当终端壳体与第一壳体连接时，该摄像头组件与终端壳体上的摄像头区域相对设置。该终端可以是手机、平板电脑、笔记本等。
本申请实施例对上述第一壳体和终端壳体的连接方式不进行限定，只要能够保证第一壳体和终端壳体连接即可。示例性的，该终端壳体可以与第一壳体一体式连接，或者该终端壳体可以与第一壳体可拆卸连接。例如，在第一壳体周圈粘胶，或胶水点胶，然后将终端壳体固定在粘胶，或胶水点胶的地方。
示例性的，本申请实施例中的终端可以为平板电脑、手机、MP4。
应理解，该终端中还可以具有其他元器件，具体的元器件可以参考现有技术中终端的设置。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
