具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
应理解，说明书通篇中提到的“一个实施例”或“一实施例”意味着与实施例有关的特定特征、结构或特性包括在本发明的至少一个实施例中。因此，在整个说明书各处出现的“在一个实施例中”或“在一实施例中”未必一定指相同的实施例。此外，这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。
在本发明的各种实施例中，应理解，下述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
图1是本发明实施例提供的一种极点屏100垂直截面的结构示意图， 参见图1，该极点屏100包括依次设置的盖板101、光学透明胶102、偏光层103、第一玻璃层104、间隙层105以及第二玻璃层106，其中，所述偏光层103包括偏光片1031和光学透明树脂1032。
其中，所述第一玻璃层104的第一表面1041、所述第二玻璃层106的第二表面1061以及所述第二玻璃层106的第三表面1062镀有抗反射膜，所述抗反射膜的覆盖区域包括所述极点屏的极点孔区，所述第一表面1041与所述第二表面1061相对。所述极点孔区可以是所述极点屏中入射光能够透过极点屏到达屏下摄像头的某个预设区域。
本发明实施例中，以AMOLED极点屏为例，如图1所示，在极点屏100中，由盖板101、光学透明胶102、偏光层103、第一玻璃层104、间隙层105以及第二玻璃层106依次设置组成，偏光层103包括偏光片1031和光学透明树脂1032。其中，间隙层105的不连续结构架空了第一玻璃层104与第二玻璃层105，形成了真空区域，从而构成了玻璃-真空-玻璃的层叠形式。由于在光传输过程中，真空介质的折射率为1，玻璃介质的折射率为1.5，差别较大，因此，当摄像头被放置在现有技术中的极点屏下时，入射光从盖板101入射，经过光学透明胶102、偏光层103、第一玻璃层104、间隙层105以及第二玻璃层106时，由于第一玻璃层104、间隙层105、以及第二玻璃层106的玻璃-真空-玻璃的层叠形式，导致入射光发生反射，产生光路干扰，最终造成拍照时出现杂色光圈的现象。
本发明实施例中，将入射光进入极点屏的方向，即从盖板101、光学透明胶102、偏光层103、第一玻璃层104、间隙层105到第二玻璃层106的方向看作由上到下，在第一玻璃层104的第一表面1041、所述第二玻璃层106的第一表面1061、以及所述第二玻璃层106的第二表面1062镀抗反射膜，从而避免入射光在进入折射率不同的介质时发生的反射现象，消除了极点屏屏下摄像头在拍摄过程中出现杂色光圈的问题。可选地，出于节省制造成本、减少极点屏厚度的目的，可以在第一玻璃层104的第一表面1041、所述第二玻璃层106的第二表面1061以及所述第二玻璃层106的第三表面1062中的至少一面镀抗反射膜，以部分消除反射现象，减弱杂色光圈问题的发生。另外，极点孔区可以是入射光能够透过极点屏到达 屏下摄像头的区域，如图1所示在偏光层103中，入射光能够透过光学透明树脂1032，而不能透过偏光片1031到达屏下摄像头。因此，偏光层103的极点孔区包括除偏光片1031外的光学透明树脂1032覆盖的区域。在偏光层103以下的第一玻璃层104、间隙层105、以及第二玻璃层106，各分层的极点孔区可以大于或等于偏光层的极点孔区，从而使得覆盖区域包括极点孔区的抗反射膜能够更好的消除反射现象，避免杂色光圈的产生。
可选地，所述抗反射膜包括交替叠加的包括交替叠加的第一膜层与第二膜层；所述第一膜层的折射率低于所述第二膜层的折射率。
本发明实施例中，抗反射膜的作用机理在于通过采用折射率不同的膜层交替叠加，从而使反射光互相抵消，透射光相位互相增强，因此，在抗反射膜的镀膜过程中，只需要保持交替叠加第一膜层和第二膜层中，先镀的第一膜层折射率低于后镀的第二膜层折射率即可，具体的材质可以由工艺条件及工艺成本自行选择。
可选地，所述第一膜层与所述第二膜层交替叠加的层数大于或等于5。
本发明实施例中，为了保证抗反射膜防反射的效果，可选地，使得第一膜层与第二膜层交替叠加的层数大于或等于5，以通过增加抗反射膜中第一膜层与第二膜层的层数，增强抗反射膜的防反射效果，通常情况下，第一膜层与第二膜层交替叠加的层数越多，抗反射膜的厚度越厚，不过也与第一膜层与第二膜层本身的厚度有关。因此，为了避免抗反射膜厚度过厚，导致极点屏屏幕厚度增加的问题，可以对第一膜层与第二膜层的层数进行控制，本发明实施例对具体抗反射膜的层数上限不做限制。
可选地，所述第一膜层包括二氧化硅层。
可选地，所述第二膜层包括二氧化钛层、五氧化二铌层、钛酸镧层、氮化硅层中的任意一种。
本发明实施例中，抗反射膜可以分别是二氧化钛层和二氧化硅层、钛酸镧层和二氧化硅层、五氧化二铌层和二氧化硅层、氮化硅层和二氧化硅层等分别交替叠加组成的。以二氧化钛层和二氧化硅层为例，交替叠加5 层为二氧化硅层-二氧化钛层-二氧化硅层-二氧化钛层-二氧化硅层本发明实施例对具体镀膜的材质不做限制。
可选地，所述抗反射膜的厚度为100-500纳米。
本发明实施例中，可以控制抗反射膜的厚度为100-500纳米，其中包括100纳米、200纳米、300纳米、400纳米、500纳米等，100-500纳米中的任意数值，从而避免抗反射膜过薄，使得防反射效果较差，或抗反射膜过厚，影响极点屏厚度等。
可选地，所述第一玻璃层104包括封装玻璃。
可选地，所述第二玻璃层106包括低温多晶硅基板。
本发明实施例中，当极点屏应用于AMOLED屏时，其第一玻璃层104可以是封装玻璃，第二玻璃层106可以是低温多晶硅基板，可选地，极点屏也可以应用于其他屏幕，如OLED屏、LCD屏等，本发明实施例对此不做具体限制。
可选地，所述抗反射膜的覆盖区域包括：所述第一玻璃层104的第一表面1041、所述第二玻璃层106的第二表面1061以及所述第二玻璃层106的第三表面1062分别对应的整个表面区域。
如图2所示，本发明实施例中，抗反射膜的覆盖区域可以包括第一玻璃层104的第一表面1041、第二玻璃层106的第二表面1061以及第二玻璃层106的第三表面1062分别对应的表面整个区域，即以全覆盖的形式镀抗反射膜，从而进一步保证防反射效果。
图2是本发明实施例提供的另一种极点屏200垂直截面的结构示意图，参见图2，该极点屏200包括依次设置的盖板201、光学透明胶202、偏光层203、第一玻璃层204、间隙层205以及第二玻璃层206，其中偏光层203包括偏光片2031和光学透明树脂2032。
可选地，所述第一玻璃层204的第一表面2041、所述第二玻璃层206的第二表面2061以及所述第二玻璃层206的第三表面2062镀有抗反射膜，所述抗反射膜的覆盖区域包括所述极点屏的极点孔区，所述第一表面2041与所述第二表面2061相对。
可选地，抗反射膜覆盖的区域包括所述第一玻璃层204的第一表面 2041、所述第二玻璃层206的第二表面2061以及所述第二玻璃层206的第三表面2062对应的极点孔区，极点孔区包括极点屏上极点孔所处的区域，在整个表面上，仅极点孔区设置抗反射膜，从而在节省材料、降低极点屏厚度的同时，保证了极点屏的防反射效果。
图3是本发明实施例提供的一种极点屏中极点孔区示意图，如图3所示，以A-A表示极点孔区的直径或边长，在具体应用中，极点孔区可以稍大于极点孔，可选地，极点孔区可以是直径为A-A的极点孔同心圆圆形区域，也可以是边长为A-A的包含极点孔的矩形区域等，从而在节省材料、降低极点屏厚度的同时，进一步保证极点屏的防反射效果。
可选地，本发明实施例提供了一种极点屏制备方法，所述极点屏包括依次设置的盖板、光学透明胶、偏光层、第一玻璃层、间隙层以及第二玻璃层，其中，所述偏光层包括偏光片和光学透明树脂；该方法可以包括：
通过预设镀膜工艺，在所述第一玻璃层的第一表面、所述第二玻璃层的第二表面、以及所述第二玻璃层的第三表面上镀抗反射膜，其中，所述抗反射膜的覆盖区域包括所述极点屏的极点孔区，所述第一表面与所述第二表面相对，所述抗反射膜的镀膜工艺包括电子束蒸镀工艺、磁控溅射镀膜工艺中的一种。
可选地，所述第一玻璃层104的镀膜温度为200℃以下。
可选地，所述第二玻璃层106的镀膜温度为60℃以下。
本发明实施例中，对于具体镀膜的工艺不做具体限制，本领域技术人员可以根据不同的玻璃材质、抗反射膜材质等选择不同的镀膜工艺，可选地，可以包括电子束蒸镀工艺、磁控溅射镀膜工艺中的一种，其中，根据不同玻璃层的功能和材质，可以选择不同的镀膜温度，对于第二玻璃层来说，由于包括温度敏感的发光材料，因此，为了避免对发光材料造成损伤，可以控制镀膜温度在60℃以下；而第一玻璃层由于不包括温度敏感材料，因此，可以在更大范围内的镀膜温度下镀膜，如镀膜温度可以包括300℃以下。
以上介绍了本发明实施例提供的极点屏以及极点屏的制备方法，下面将结合附图示例详细介绍本发明实施例提供的一种极点屏的制备方法，以 AMOLED屏为例，制备方法如下：

移动终端800还包括至少一种传感器805，比如光传感器、运动传感器以及其他传感器。具体地，光传感器包括环境光传感器及接近传感器，其中，环境光传感器可根据环境光线的明暗来调节显示面板8061的亮度，接近传感器可在移动终端800移动到耳边时，关闭显示面板8061和/或背光。作为运动传感器的一种，加速计传感器可检测各个方向上(一般为三轴)加速度的大小，静止时可检测出重力的大小及方向，可用于识别移动终端姿态(比如横竖屏切换、相关游戏、磁力计姿态校准)、振动识别相关功能(比如计步器、敲击)等；传感器805还可以包括指纹传感器、压力传感器、虹膜传感器、分子传感器、陀螺仪、气压计、湿度计、温度计、红外线传感器等，在此不再赘述。
显示单元806用于显示由用户输入的信息或提供给用户的信息。显示 单元606可包括显示面板8061，可以采用液晶显示器(Liquid Crystal Display，LCD)、有机发光二极管(Organic Light-Emitting Diode，OLED)等形式来配置显示面板8061，可选地，显示面板806包括如图1所示的极点屏，其中，包括依次设置的盖板101、光学透明胶102、偏光层103、第一玻璃层104、间隙层105以及第二玻璃层106，其中，所述偏光层103包括偏光片1031和光学透明树脂1032；
所述第一玻璃层104的第一表面1041、所述第二玻璃层106的第二表面1061以及所述第二玻璃层106的第三表面1062镀有抗反射膜，所述抗反射膜的覆盖区域包括所述极点屏的极点孔区，所述第一表面1041与所述第二表面1061相对。
本发明实施例中，通过在第二玻璃层的第二表面和第三表面，以及第一玻璃层的第一表面均镀有抗反射膜，当入射光从第一玻璃层的第一表面进入间隙层间的真空层，以及从第二玻璃层的第二表面离开真空层进入第二玻璃层，再从第二玻璃层的第三表面离开的过程中，能够避免光线反射造成的光路干扰，解决了屏下摄像出现杂色光圈的问题，提高拍摄效果。
用户输入单元807可用于接收输入的数字或字符信息，以及产生与移动终端的用户设置以及功能控制有关的键信号输入。具体地，用户输入单元807包括触控面板8071以及其他输入设备8072。触控面板8071，也称为触摸屏，可收集用户在其上或附近的触摸操作(比如用户使用手指、触笔等任何适合的物体或附件在触控面板8071上或在触控面板8071附近的操作)。触控面板8071可包括触摸检测装置和触摸控制器两个部分。其中，触摸检测装置检测用户的触摸方位，并检测触摸操作带来的信号，将信号传送给触摸控制器；触摸控制器从触摸检测装置上接收触摸信息，并将它转换成触点坐标，再送给处理器810，接收处理器810发来的命令并加以执行。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型实现触控面板8071。除了触控面板8071，用户输入单元807还可以包括其他输入设备8072。具体地，其他输入设备8072可以包括但不限于物理键盘、功能键(比如音量控制按键、开关按键等)、轨迹球、鼠标、操作杆，在此不再赘述。
进一步的，触控面板8071可覆盖在显示面板8061上，当触控面板6071检测到在其上或附近的触摸操作后，传送给处理器810以确定触摸事件的类型，随后处理器810根据触摸事件的类型在显示面板8061上提供相应的视觉输出。虽然在图8中，触控面板8071与显示面板8061是作为两个独立的部件来实现移动终端的输入和输出功能，但是在某些实施例中，可以将触控面板8071与显示面板8061集成而实现移动终端的输入和输出功能，具体此处不做限定。
接口单元808为外部装置与移动终端800连接的接口。例如，外部装置可以包括有线或无线头戴式耳机端口、外部电源(或电池充电器)端口、有线或无线数据端口、存储卡端口、用于连接具有识别模块的装置的端口、音频输入/输出(I/O)端口、视频I/O端口、耳机端口等等。接口单元808可以用于接收来自外部装置的输入(例如，数据信息、电力等等)并且将接收到的输入传输到移动终端800内的一个或多个元件或者可以用于在移动终端800和外部装置之间传输数据。
存储器809可用于存储软件程序以及各种数据。存储器809可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等；存储数据区可存储根据手机的使用所创建的数据(比如音频数据、电话本等)等。此外，存储器809可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
处理器810是移动终端的控制中心，利用各种接口和线路连接整个移动终端的各个部分，通过运行或执行存储在存储器809内的软件程序和/或模块，以及调用存储在存储器809内的数据，执行移动终端的各种功能和处理数据，从而对移动终端进行整体监控。处理器810可包括一个或多个处理单元；优选的，处理器810可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器810中。
移动终端800还可以包括给各个部件供电的电源811(比如电池)，优选的，电源811可以通过电源管理系统与处理器810逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
另外，移动终端800包括一些未示出的功能模块，在此不再赘述。
在本发明实施例的一些可能实现中，移动终端800可以为包括上述极点屏的电子设备。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本发明各个实施例所述的方法。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本发明的保护之内。
