具体实施方式
下面将结合附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、 “一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在描述一些实施例时，可能使用了“连接”及其衍伸的表达。例如，描述一些实施例时可能使用了术语“连接”以表明两个或两个以上部件彼此间有直接物理接触或电接触。
“A和/或B”，包括以下三种组合：仅A，仅B，及A和B的组合。
另外，“基于”的使用意味着开放和包容性，因为“基于”一个或多个所述条件或值的过程、步骤、计算或其他动作在实践中可以基于额外条件或超出所述的值。
如本文所使用的那样，“近似”或“大致”包括所阐述的值以及处于特定值的可接受偏差范围内的平均值，其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差(即，测量***的局限性)所确定。
本文参照作为理想化示例性附图的剖视图和/或平面图描述了示例性实施方式。在附图中，为了清楚，放大了层和区域的厚度。因此，可设想到由于例如制造技术和/或公差引起的相对于附图的形状的变动。因此，示例性实施方式不应解释为局限于本文示出的区域的形状，而是包括因例如制造而引起的形状偏差。例如，示为矩形的蚀刻区域通常将具有弯曲的特征。因此，附图中所示的区域本质上是示意性的，且它们的形状并非旨在示出设备的区域的实际形状，并且并非旨在限制示例性实施方式的范围。
图1A和图1B示出了本公开一些实施例中的显示装置200。如图1A和图1B所示，该显示装置200中包括显示模组100，显示模组100的显示面板中具有指纹识别区域S。当手指按压在该指纹识别区域S上时，光线(例如显示面板发出的光线)照射至指纹(即手指纹理)上，然后由指纹反射到显示面板下方的光学指纹传感器上，从而产生指纹图像， 对该显示装置200进行解锁。此处，需要说明的是，该指纹识别区域S需要能够使经指纹反射的光线穿过后射向光学指纹传感器。该指纹识别区域S的位置和形状可以有多种设置方式，例如，该指纹识别区域S的形状可以大致为矩形(例如长方形、或者如图1A所示的正方形)，也可以大致为圆形(如图1B所示)，或者还可以大致为圆角矩形等。其中，“大致”指的是包括所阐述的形状和整体上与所阐述的形状相类似的形状。例如，对于“大致呈圆形”而言，可以是圆形，也可以是整体上与圆形相类似的形状，该形状的至少部分边界允许与圆形的至少部分边界不同，也即该形状的至少部分边界允许是非曲线形的，例如该形状的至少部分边界可以为锯齿形等。同样的，可以理解，对于“大致呈矩形”、“大致为圆角矩形”而言，也并不局限于标准的矩形和圆角矩形。
又例如，该指纹识别区域S可以位于显示模组100中显示面板的边缘区域(如图1A所示)，或者，也可以位于显示模组100中显示面板的中间区域(如图1B所示)。
上述显示装置200可以是OLED显示装置，例如AMOLED显示装置。此外，上述显示装置200可以是电视、数码相机、手机、手表、平板电脑、笔记本电脑、导航仪等任何具有显示功能的部件。
本公开一些实施例提供了一种应用于上述显示装置200中的显示模组100。如图2A所示，该显示模组100包括显示面板1，第一保护层2和金属保护层3。
显示面板1包括指纹识别区域S。该显示面板1可以是OLED显示面板，例如AMOLED显示面板等。
第一保护层2设置于显示面板1的背面11，该显示面板1的背面11为显示面板1中与显示面板1的显示面12(该显示面12例如可以显示文字、图像或视频等)相对的表面。第一保护层2中设置有用于暴露出指纹识别区域S的第一开口21，例如该第一开口21的形状大小可以与指纹识别区域S的形状大小均相同或近似相同，这样使得经指纹反射的光线可以更多的穿过该第一开口21。
金属保护层3位于第一保护层2远离显示面板1一侧的表面，金属保护层3中设置有第二开口31，第二开口31暴露出第一开口21。其中，第二开口31的边缘在显示面板1上的正投影位于第一开口21的边缘在显示面板1上的正投影的外侧，此时，第二开口31的边缘在显示面板1上的正投影和第一开口21的边缘在显示面板1上的正投影可以完全不接触，也可以部分接触。 可以理解，该第二开口31的开口面积应当大于该第一开口21的开口面积。
这样设置，在与光学指纹传感器配合安装后(例如光学指纹传感器5可以按照图2B示出的方式与显示面板1、第一保护层2以及金属保护层3配合安装，也即，可以将该光学指纹传感器5设置于金属保护层3远离第一保护层2的一侧，且使该光学指纹传感器5正对显示面板1的指纹识别区域S)，使得经指纹反射的光线在通过第一开口21射向光学指纹传感器5且被光学指纹传感器5反射后，不容易射向金属保护层3，从而不容易出现金属保护层3将光线再次反射至光学指纹传感器5的情况，改善了因金属保护层3反射光线而对光学指纹传感器5造成的光学干扰，进而提高了显示模组100的指纹识别效率和准确率。
此处，值得指出的是，相较于将第一保护层2与金属保护层3的开口面积同时增大至相同的尺寸而言，上述一些实施例中通过设置第一开口21用于暴露出指纹识别区域S，第二开口31的边缘在显示面板1上的正投影位于第一开口21的边缘在显示面板1上的正投影的外侧，可以在改善因金属保护层3反射光线而对光学指纹传感器5造成光学干扰的问题的同时，防止因第一保护层2和金属保护层3中的开口均比较大而降低第一保护层2和金属保护层3对显示面板1的支撑和保护效果。例如，由于显示面板1硬度较差，在第一保护层2和金属保护层3的开口均比较大的情况下，贴合第一保护层2和金属保护层3后容易产生出现贴合断差，进而造成显示面板1上容易出现压痕。而本公开上述一些实施例中提供的显示模组100可以较好的改善这一问题。
其中，第一保护层2为不反射光线的膜层，这样在光线照射至该第一保护层2后，不会被该第一保护层2反射至光学指纹传感器5上，因此不会对光学指纹传感器5造成光学干扰。
作为一种可能的设计，如图3所示，该第一保护层2包括依次层叠设置于显示面板1背面11的网纹胶层22和缓冲层23。这样设置，能够使得网纹胶层22与显示面板1、缓冲层23连接地更加紧密，从而使得网纹胶层22和缓冲层23能够更好地被固定在显示面板1上，能够起到较好的缓冲和遮光效果。
其中，网纹胶层22的材料可以是黑色网纹胶，缓冲层23的材料可以是泡棉。泡棉重量轻且具有弹性，能够对显示面板1及其下方的电路结构进行保护，例如，在显示面板1受到较大的作用力时，由于显示面板1的背面不直接与刚性部件接触，使得显示面板1不易损坏，同时， 位于显示面板1下方的电路结构也不会因显示面板1的挤压而损坏。
此处，可以理解的是，该网纹胶层22和缓冲层23中的开口可以共同用于构成上述第一开口21。在一些示例中，该网纹胶层22的开口边缘在显示面板1上的正投影和该缓冲层23的开口边缘在显示面板1上的正投影重叠。当然，在另一些示例中，也可以设置这两者不重叠，只需保证金属保护层3的第二开口21的边缘在显示面板1上的正投影位于网纹胶层22的开口边缘在显示面板1上的正投影的外侧，且该金属保护层3的第二开口21的边缘在显示面板1上的正投影位于缓冲层23的开口边缘在显示面板1上的正投影的外侧即可。本公开对此不进行限制。
作为一种可能的设计，金属保护层3包括铜层。该铜层的材料可以是铜，也可以是铜合金。通过这样设置，能够提高散热效果，使显示面板1上的热量能够更快的散发。同时能够防止外界环境光等其它杂散光线直接照射至光学指纹传感器5上，提高了显示模组100的指纹识别效率和指纹识别准确率。
在一些实施例中，如图4A所示，该显示模组100还包括柔性电路板4和光学指纹传感器5。
柔性电路板4设置于金属保护层3远离第一保护层2的一侧，且柔性电路板4上设置有第三开口41，第三开口41的边缘在显示面板1上的正投影位于第二开口31的边缘在显示面板1上的正投影的内侧。此时，该第三开口41的边缘在显示面板1上的正投影和第二开口31的边缘在显示面板1上的正投影可以完全不接触，也可以部分接触。可以理解，该第二开口31的开口面积应当大于该第三开口41的开口面积。
光学指纹传感器5设置于柔性电路板4远离金属保护层3的一侧。光学指纹传感器5在显示面板1上的正投影位于第三开口41的边缘在显示面板1上的正投影的内侧。此时，该光学指纹传感器5在显示面板1上的正投影和第三开口41的边缘在显示面板上的正投影可以完全不接触，也可以部分接触。可以理解，该第三开口41的开口面积应当大于该光学指纹传感器5在显示面板1上的正投影面积。
其中，由于光学指纹传感器5是利用由显示模组100上方的指纹反射回显示模组100的光线来实现指纹识别检测，而柔性电路板4位于光学指纹传感器5与显示面板1之间，且柔性电路板4不透光，因此在柔性电路板4上设置该第三开口41，可以使反射回到显示模组100的光线能够照射至光学指纹传感器5上。
在此基础上，通过设置第三开口41的边缘在显示面板1上的正投影位于第二开口31的边缘在显示面板1上的正投影的内侧，且光学指纹传感器5在显示面板1上的正投影位于第三开口41的边缘在显示面板1上正投影的内侧，一方面，使指纹反射回显示模组100的光线能够穿过柔性电路板4上的第三开口41后照射到光学指纹传感器5上，不容易出现光学指纹传感器5中仅部分位置能够接收指纹反射回的光线、或光学指纹传感器5完全不能够接收到指纹反射回的光线的情况，因此使得光学指纹传感器5能够接收到更多的光线，进而提高了光学指纹传感器5的指纹识别效率和准确率。另一方面，可以利用柔性电路板4对光学指纹传感器5反射出的光线进行阻挡，防止光学指纹传感器5的反射光线照射到金属保护层3，从而不易出现金属保护层3将光学指纹传感器5的反射光线反射回光学指纹传感器5的情况，也即不易对光学指纹传感器5造成光学干扰。
值得指出的是，在第一保护层2和金属保护层3贴覆至显示面板上时，容易产生贴覆误差，也即，如图4B所示，容易使得第一开口21的边缘在显示面板1上的正投影落在指纹识别区域S内。此时，第三开口41将暴露出部分第一保护层2。然而，由于本公开一些实施例中，设置第二开口31的边缘在显示面板1上的正投影位于第一开口21的边缘在显示面板1上的正投影的外侧，使得即使第一保护层2和金属保护层3整体产生贴附误差，第三开口41也不容易暴露出金属保护层3(如图4B所示)，因此，这样可以更好的防止光学指纹传感器5将光线反射至金属保护层3，进而防止金属保护层3反射光线对光学指纹传感器5造成光学干扰。
作为一种可能的设计，参见图4A和图4B，第二开口31的边缘在显示面板1上的正投影中各个点到第一开口21的边缘在显示面板1上的正投影的最短距离d1为0.2mm～0.5mm，例如，d1可以为0.2mm、0.3mm或0.5mm等。此处，该第二开口31和第一开口21可以形状大致相同，也可以形状不相同。其中，“形状大致相同”指的是这两者的形状可以完全相同，或者这两者中一者的形状可以为整体上与另一者形状相类似的形状。
通过这样设置，一方面，使得第二开口31的边缘在显示面板1上的正投影和第一开口21的边缘在显示面板1上的正投影之间的间距较远，这样在第一保护层2和金属保护层3产生贴覆误差的情况下，光学指纹传感器5反射的光线也不容易照射至金属保护层3，进而不易出现金属 保护层3将光线在此反射回光学指纹传感器5的情况，从而改善了对光学指纹传感器5造成的光学干扰。另一方面，能够使第二开口31的面积相对较小，即金属保护层3在显示面板1上的投影面积相对较大，从而还可以为显示面板1提供较好的支撑和保护，并使显示面板1上的热量能够较快的散发。
在此基础上，示例性的，如图4A所示，第三开口41的边缘在显示面板1上的正投影中各个点和第二开口31的边缘在显示面板1上的正投影的最短距离d2小于或等于1mm。此处，该第三开口41和第二开口31可以形状大致相同，也可以形状不相同。其中，“形状大致相同”指的是这两者的形状可以完全相同，或者这两者中一者的形状可以为整体上与另一者形状相类似的形状。
这样设置，第三开口41不直接暴露出金属保护层3，因此可以利用柔性电路板4对光学指纹传感器5的反射光线进行遮挡，从而使得光学指纹传感器5的反射光线不会直接射线金属保护层3，改善了因金属反射层3反射光线至光学传感器5而导致的对光学指纹传感器5造成光学干扰的问题，提高了光学指纹传感器5的指纹识别效率和准确率。
示例性的，如图4A所示，第三开口41的边缘在显示面板1上的正投影中各个点到光学指纹传感器5在显示面板1上的正投影的最短距离d3小于或等于1mm。
这样设置，一方面，柔性电路板4不会对光学指纹传感器5造成遮挡，即经指纹反射的光线仍能够顺利达到光学指纹传感器5，从而使得光学指纹传感器5面向显示面板1的部分均能够接收到指纹反射的光线，避免了光学指纹传感器5因接收到的指纹图像不完整所导致的指纹识别失败的情况。另一方面，不会因柔性电路板4的第三开口41过大，而导致过多的杂散光线射向光学指纹传感器5，也即，可以利用柔性电路板4对周围不必要的光线(例如金属保护层3反射的光线)进行遮挡，从而有利于提高光学指纹传感器5的指纹识别效率和准确率。
在一些实施例中，如图5所示，光学指纹传感器5在显示面板1上的正投影位于第一开口21的边缘在显示面板1上的正投影的内侧。此时，该光学指纹传感器5在显示面板1上的正投影和第一开口21的边缘在显示面板1上的正投影可以完全不接触，也可以部分接触。可以理解，该光学指纹传感器5在显示面板1上的正投影位于第一开口21的边缘在显示面板1上的正投影面积应当小于该第一开口21的开口面积。
这样设置，使得光学指纹传感器5的表面不会被第一保护层2所遮挡，从而使得光学指纹传感器5面向显示面板1的表面均能够接收到由指纹反射的光线，不易出现由指纹反射的光线因被第一保护层2阻挡而不能射向光学指纹传感器5面向显示面板1的表面的情况，有利于提高指纹识别的准确性。
示例性的，如图4A所示，第一开口21的边缘在显示面板1上的正投影中各个点到光学指纹传感器5在显示面板1上的正投影的最短距离d4小于或等于1mm。
这样设置，一方面，第一保护层2不会对光学指纹传感器5造成遮挡，即经指纹反射的光线能够顺利达到光学指纹传感器5，从而使得光学指纹传感器5面向显示面板1的部分均能够接收到指纹反射的光线，避免了光学指纹传感器5因接收到的指纹图像不完整所导致的指纹识别失败的情况。另一方面，不会因第一保护层2的第一开口21过大，而导致过多的杂散光线射向光学指纹传感器5，也即，可以利用第一保护层2对周围不必要的光线(例如外界环境光)进行遮挡，从而有利于提高光学指纹传感器5的指纹识别效率和准确率。
在一些实施例中，如图4A所示，第三开口41的边缘在显示面板1上的正投影和第一开口21的边缘在显示面板1上的正投影大致重叠(此处，“大致重叠”是指完全重叠，或者两者正投影之间可以存在由于制作误差而导致的合理偏差，例如该偏差可以小于0.5mm)。通过这样设置，由用户指纹反射后的显示面板1所发出的光线易于在通过第一开口21和第二开口31后直接通过第三开口41，避免经过第一开口21后的光线在经过第三开口41时，被柔性电路板4阻挡从而不能照射至光学指纹传感器5上，从而提高了照射至光学指纹传感器上5的光线量，有效地增加了光学指纹传感器5的识别效率和准确率。
在一些实施例中，如图5所示，显示模组100还包括主控电路板6，主控电路板6上设置有光学指纹传感器5，并且主控电路板6通过柔性电路板4连接至显示面板1。这样设置，不仅可以通过主控电路板6和柔性电路板4控制显示面板1显示画面，并且可以在用户指纹按压至指纹识别区域S时，实现根据光学指纹传感器5识别到的指纹信息确定是否解锁显示装置，例如，可以在指纹信息验证正确的情况下解锁该显示装置，而在指纹信息验证失败的情况下使该显示装置保持锁定状态。
在本公开的一些实施例中，如图6所示，显示模组100还包括第一电磁屏蔽膜7，第一电磁屏蔽膜7设置于柔性电路板4靠近金属保护层3 一侧的表面上。其中，第一电磁屏蔽层4上对应第三开口41的位置处设置有第四开口71，通过第四开口71使光线可以从第二开口31传播至第三开口41。
在本公开的一些实施例中，如图6所示，本公开所提供的显示模组100还包括第二电磁屏蔽膜8，第二电磁屏蔽膜8设置于柔性电路板4远离金属保护层3一侧的表面上。第二电磁屏蔽膜8对应于第三开口41的位置处设置有第五开口81，通过第五开口81使得指纹反射回显示模组100的光线能够经第三开口41后射向光学指纹传感器5。
需要说明的是，显示模组100可以仅包括第一电磁屏蔽膜7，也可仅包括第二电磁屏蔽膜8，还可以同时包括第一电磁屏蔽膜7和第二电磁屏蔽膜8。本方案中，通过设置电磁屏蔽膜，可以防止柔性电路板4上的电路受到电磁干扰，从而不易对显示效果造成影响。
在一些实施例中，如图7所示，显示模组100还包括保护盖板9，保护盖板9设置在显示面板1远离第一保护层2一侧的表面上。保护盖板9用于保护显示面板1，防止显示面板1在外界作用力的影响下产生变形，同时防止水汽进入到显示模组100中，对显示模组100中的电路结构造成不良影响。
另外，需要说明的是，本公开一些实施例提供的显示装置200，参见图1A和图1B，由于包含上述任一实施例所述的显示模组100，因此，该显示装置200所能够达到的技术效果与显示模组100所能够达到的技术效果相同，此处不再赘述。
基于上述显示模组100，本公开的实施例提供一种显示模组100的制作方法，包括：
S1：提供显示面板，显示面板包括指纹识别区域；
S2：将具有第一开口的第一保护层贴附在显示面板的背面，所述背面为显示面板上与显示面板的显示面相对的表面，第一保护层的第一开口暴露出指纹识别区域；
S3：将具有第二开口的金属保护层贴附在第一保护层远离显示面板一侧的表面上，第二开口暴露出第一开口；第二开口的边缘在显示面板上的正投影位于第一开口的边缘在显示面板上的正投影的外侧。
其中，需要说明的是，具有第一开口的第一保护层，可以通过模切工艺切割第一保护层直接得到的。同理，具有第二开口的金属保护层，可以通过模切工艺切割金属保护层直接得到的。
利用上述显示模组的制作方法所得到的显示模组100，即使在将第一保护层2贴覆至显示面板1上时出现偏差，由于金属保护层3上第二开口31的边缘在显示面板1上的正投影位于第一开口21的边缘在显示面板1上的正投影的外侧，使得对应指纹识别区域S的光学指纹传感器5反射的光线不容易照射至金属保护层3上，避免金属保护层3将光线反射至光学指纹传感器5上，有利于提高光学指纹传感器5指纹识别效率和指纹识别的准确率，进而提高显示模组100的指纹识别效率和准确率，提升用户体验感。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
