根据本申请实施例的电子设备，包括上述的显示模组。
根据本申请实施例的电子设备，由于显示模组的保护层的至少部分超出基板的外周壁，因此保护层的超出基板的部分能对基板起到一定的防护作用，从而在显示模组的制造加工或者产品测试(例如跌落测试或者震动测试)中，基板的外周壁便不容易受到磕碰而发生损坏的现象，此外，由于密封层包括相连的第一密封部分和第二密封部分，第一密封部分设在保护层的超出基板的外周壁的部分上，第二密封部分设在基板和保护层之间且位于显示层的外周，因此使得密封层具有较大的有效阻水宽度，阻水效果较好。
根据本申请实施例的显示模组的制造方法，所述显示模组为上述的显示模组，所述制造方法包括：分别加工出所述显示层、所述基板和所述保护层；将所述显示层粘贴至所述基板；在所述显示层的背离所述基板的一侧表面粘贴所述保护层；在所述保护层上涂覆防水胶；固化所述防水胶以形成所述密封层。
根据本申请实施例的显示模组的制造方法，由于是在保护层上涂覆防水胶，因此能 较好地满足显示模组中密封层的结构形式需求，而且涂布方法简单，便于实现。

具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考附图描述根据本申请实施例的显示模组100、电子设备和显示模组100的制造方法，显示模组100例如可为电子纸显示的显示模组100，电子纸显示是一种新兴 的显示技术，具有超轻薄、可重写、便于携带、超低功耗、断电时也能保持显示等特性。实现电子纸显示的技术有很多，常用技术是E-Ink微胶囊(Micro-capsules)式电泳技术，具体原理是将带电的白色氧化钛颗粒和黑色碳粉粒子封装在微胶囊中，并将微胶囊和电解液封装在两块间距为10mm～100mm的平行导电板之间，利用带电颗粒在电场作用下向着与其电性相反的电极移动的特性，绘制出黑白图像。
如图5和图8所示，根据本申请实施例的显示模组100，包括基板1、显示层2、保护层3和密封层4。
如图5、图6和图7所示，显示层2设在基板1的一侧(例如图中基板1的上侧)且与基板1电连接，由此基板1通电后便可驱动显示层2显示。在平行于基板1的平面内，显示层2的投影位于基板1的投影内，由此使得显示层2不会超出基板1，避免影响到显示层2的正常显示。
如图5、图7和图8所示，保护层3设在显示层2的远离基板1的一侧(例如图中显示层2的上侧)，保护层3可对显示层2起到保护作用，例如可防止外界的水汽、灰尘等与显示层2接触从而影响显示层2的正常显示以及还可避免有硬物等划伤显示层2导致显示层2损坏。保护层3的至少部分超出基板1的外周壁，具体而言，例如可以是保护层3的某一侧边缘的部分超出基板1的相应边缘，或者是保护层3的某一侧的整个边缘超出基板1的相应边缘，也可以是保护层3的全部边缘均超出基板1的相应边缘，由此使得保护层3的超出基板1的部分还能对基板1起到一定的防护作用，从而在显示模组100的制造加工或者产品测试(例如跌落测试或者震动测试)中，基板1的外周壁便不容易受到磕碰而发生损坏的现象。在平行于基板1的平面内，显示层2的投影位于保护层3的投影内，由此保护层3可完全覆盖显示层2，从而能对显示层2起到更好的保护作用。
具体而言，例如，参照图5和图8，基板1大致呈方形形状，显示层2位于基板1上方，保护层3位于显示层2上方，基板1的外周边缘超出显示层2的外周边缘，保护层3的前侧边缘超出基板1的前侧边缘，保护层3的后侧边缘超过基板1的后侧边缘，保护层3的左侧边缘的部分超出基板1的左侧边缘，保护层3的右侧边缘超过基板1的右侧边缘。
如图7、图8和图9所示，密封层4包括相连的第一密封部分41和第二密封部分42，第一密封部分41设在保护层3的超出基板1的外周壁的部分上，第二密封部分42设在基板1和保护层3之间且位于显示层2的外周，由此密封层4可起到密封作用，能阻止外界的水汽等进入显示层2从而对显示层2造成不良影响，而且对于显示层2而言， 密封层4中最主要起到阻水效果的是位于基板1和保护层3之间的第二密封部分42，因此使得密封层4具有较大的有效阻水宽度，阻水效果较好。
实际应用中，密封层4通常为防水胶，在电子纸产品的制造生产中，这种防水胶为EC胶，黏性强，而且流动性好，能够方便快速地渗入保护层3与基板1之间并扩散到显示层2的边缘。
相关技术中一些电子纸显示的显示模组100的大致结构如图1和图2所示，基板1上设有显示层2，显示层2上设有保护层3，基板1的外周边缘超出保护层3的外周边缘，保护层3的外周边缘超过显示层2的外周边缘，这种结构形式的显示模组100在制造加工或者产品测试中，基板1的外周壁很容易受到磕碰而发生破裂损坏的现象，产品的不良率较高。此外，如图1、图3和图4所示，基板1上涂布有防水胶(即密封层4)，而防水胶只有较少的部分位于基板1和保护层3之间，由此使得防水胶的有效阻水宽度较小，防水胶的阻止外界水汽等进入显示层2的效果不够理想。
而根据本申请实施例的显示模组100，由于保护层3的至少部分超出基板1的外周壁，因此保护层3的超出基板1的部分能对基板1起到一定的防护作用，从而在显示模组100的制造加工或者产品测试(例如跌落测试或者震动测试)中，基板1的外周壁便不容易受到磕碰而发生损坏的现象，此外，由于密封层4包括相连的第一密封部分41和第二密封部分42，第一密封部分41设在保护层3的超出基板1的外周壁的部分上，第二密封部分42设在基板1和保护层3之间且位于显示层2的外周，因此使得密封层4具有较大的有效阻水宽度，阻水效果较好。
在本申请的一些实施例中，如图9所示，第二密封部分42在显示层2的整个周向方向上环绕显示层2设置且与显示层2的外周壁相连，由此可进一步提高密封层4的阻水效果。
在本申请的一些实施例中，如图8和图9所示，保护层3的超出基板1的外周壁的部分均设有第一密封部分41，第一密封部分41与基板1的外周壁相连，由此不仅方便在制造过程中使防水胶能迅速渗入保护层3与基板1之间并扩散到显示层2的整个外周边缘，而且当防水胶固化后，粘连在保护层3的超出基板1的外周壁的部分上的第一密封部分41可在一定程度上提高保护层3该区域的抗变形能力，从而能提高保护层3对于基板1的保护效果。
在本申请的一些实施例中，如图5和图8所示，保护层3的外周壁(例如图中保护层3的左侧壁)形成有避让缺口31，在平行于基板1的平面内，基板1的一部分的投影位于避让缺口31的投影内，基板1的其余部分的投影位于保护层3的投影内，基板 1的其余部分的外周壁与保护层3的外周壁之间均设有第一密封部分41，也就是说，对于基板1而言，基板1位于避让缺口31的区域内部不设有第一密封部分41，一方面设置避让缺口31是为了避免保护层3对显示模组100的其他部件产生干涉，另一方面只在基板1的其余部分的外周壁与保护层3的外周壁之间设有第一密封部分41，可方便密封层4的涂布。
在本申请的一些实施例中，如图5所示，保护层3的外周壁形成有避让缺口31，在平行于基板1的平面内，基板1的一部分的投影位于避让缺口31的投影内，基板1的其余部分的投影位于保护层3的投影内，显示模组100包括芯片5和柔性电路板6，芯片5设在基板1上且位于避让缺口31处，基板1的与避让缺口31正对的部分与柔性电路板6电连接，由此设置避让缺口31后，可避免保护层3对邦定到基板1上的芯片5和柔性电路板6产生干涉。
具体而言，芯片5和柔性电路板6均与基板1上的薄膜晶体管阵列电连接，芯片5用于通过薄膜晶体管阵列控制显示层2显示，柔性电路板6用于与印刷电路板相连，关于芯片5和柔性电路板6通过薄膜晶体管阵列控制显示层2显示的相关过程和原理已被本领域技术人员所熟知，此处不再赘述。
此外，在制造过程中，在柔性电路板6的折弯处涂布有紫外光固化胶(即UV胶)以防止在使用过程中柔性电路板6撕裂，在芯片5上以及芯片5周围涂布有室温硫化硅橡胶胶水(即RTV胶8)，用于保护芯片5。
在本申请的一些实施例中，基板1为玻璃基板1，或者在一些柔性电子纸产品中，基板1也可为塑料基板1，在显示模组100的制造过程中，还会在玻璃基板1或者塑料基板1上制作薄膜晶体管(TFT)阵列，以用于驱动显示层2显示。当然，基板1的材质并不限于玻璃或者塑料，也可为其他材质，例如陶瓷或者柔性纤维布等等，具体可根据电子纸产品的种类或者加工需求等选择。
在本申请的一些实施例中，显示层2为电子墨水薄膜层。相关技术中，通常是将封装有液体和带电粒子的微胶囊或微杯等制成的电子墨水涂布于一层塑料薄膜上以构成电子墨水薄膜层，然后再将电子墨水薄膜层贴附到基板1上。本申请对于电子墨水的种类不作限制，例如电子墨水可为只能显示黑白颜色的电子墨水，也可为能显示彩色的电子墨水等，具体可根据电子纸产品的种类或者加工需求等选择。
在本申请的一些实施例中，保护层3为保护膜层，具体而言，为了使保护层3对显示层2具有更好的保护效果以及使保护层3具有较优异的性能，保护层3可为由多种膜结构复合而成的保护膜层。例如保护层3可包含阻水膜与光学膜，其中阻水膜位于显示 层2上可与显示层2相接触，而光学膜是位于阻水膜上。阻水膜用于阻止水汽进入显示层22，阻水膜可由无机陶瓷材料、有机高分子材料或有机无机复合材料来制造，这些材料例如为氧化硅(SiOx)、氮化硅(SiNx)、聚对二甲苯(Parylene)、聚丙烯(Polypropylene)、非晶硅/聚对二甲苯复合材料(aSi/Parylene)或聚丙烯/聚丙烯酸酯/铝复合材料(Polypropylene/polyacrylate/Al)：光学膜具有吸收紫外光的功能，例如光学膜可以是吸收紫外光的非干涉型截止滤光片，或者是可干涉紫外光的干涉型截止滤光片，当光学膜为干涉型截止滤光片时，可以通过干涉效应达到阻隔紫外光的功能，干涉型截止滤光片可包含有折射率变化的多层折射膜，而这些折射膜的材质可包含四氟化镁(MgF4)、二氧化锆(ZrO2)以及三氟化铈(CeF3)等。
当然，保护层3并不限于上述材质，例如在一些实施例中，保护层3还可为或玻璃层，具体应用时，保护层3的种类可根据电子纸产品的种类或者加工需求等选择。此外在一些电子纸产品例如柔性电子纸中，根据产品特性，保护层3还设有电极，从而可使得保护层3整体形成电极层，由此可和基板1上的薄膜晶体管阵列共同对显示层2进行驱动，相关的结构和技术原理已被本领域技术人员所熟知，此处不再赘述。
在本申请的一些实施例中，如图5所示，显示层2包括显示区域21和非显示区域22，其中显示区域21为显示层2的可进行显示的区域，例如可显示文字、图像或者颜色等内容，非显示区域22则为显示层2的不进行显示的区域，显示区域21包括画面区211和边框区212，边框区212位于画面区211和非显示区域22之间。
具体而言，例如，参照图5，画面区211大致呈方形形状，边框区212大致呈方环形形状，边框区212位于画面区211和非显示区域22之间，并且边框区212环绕画面区211设置，对于电子纸显示而言，边框区212可作为画面区211与非显示区域22之间的过渡区域。
在本申请的一些实施例中，基板1与显示层2通过导电胶7相连，由此便可通过基板1上的薄膜晶体管阵列对显示层2进行控制，以实现显示功能。
具体而言，例如，参照图5，显示层2上设有导电胶涂布点，导电胶涂布点位于非显示区域22，导电胶涂布点为两个并分布在避让缺口31的两侧，导电胶7涂布在导电胶涂布点处，导电胶7位于显示层2与基板1之间以导通显示层2和基板1。
实际应用中，导电胶7通常为银胶，银胶是一种通过基体树脂的粘接作用把导电粒子结合在一起，形成导电通路，实现被粘材料的导电连接，在显示领域中被广泛使用。
根据本申请实施例的电子设备，包括上述的显示模组100。
根据本申请实施例的电子设备，由于显示模组100的保护层3的至少部分超出基板 1的外周壁，因此保护层3的超出基板1的部分能对基板1起到一定的防护作用，从而在显示模组100的制造加工或者产品测试(例如跌落测试或者震动测试)中，基板1的外周壁便不容易受到磕碰而发生损坏的现象，此外，由于密封层4包括相连的第一密封部分41和第二密封部分42，第一密封部分41设在保护层3的超出基板1的外周壁的部分上，第二密封部分42设在基板1和保护层3之间且位于显示层2的外周，因此使得密封层4具有较大的有效阻水宽度，阻水效果较好。
如图10所示，根据本申请实施例的显示模组100的制造方法，显示模组100为上述的显示模组100，制造方法包括：
分别加工出显示层2、基板1和保护层3。这里，显示层2、基板1和保护层3的加工顺序可以是同时进行加工，也可以是先后进行加工，例如，先加工出显示层2，然后加工基板1，最后加工保护层3。当然，在另一些示例中，还可以是先加工出基板1，而后同时加工出显示层2以及保护层3。关于显示层2、基板1和保护层3的加工顺序可以根据实际生产需要进行限定。
将显示层2粘贴至基板1；
在显示层2的背离基板1的一侧表面粘贴保护层3；
在保护层3上涂覆防水胶；
固化防水胶以形成密封层4。
具体而言，在制造显示模组100时，通常是先将显示层2贴附在基板1上，然后将保护层3贴附到显示层2上，再在保护层3上沿着保护层3的外周边缘涂布防水胶，由于保护层3与基板1之间存在间隙，因此防水胶便可渗入保护层3与基板1之间，直至扩散到显示层2边缘。相较于现有技术中在基板1上涂布防水胶的方式而言，这种防水胶的涂布方法简单，便于实现，能较好地满足显示模组100中密封层4的结构形式需求。
根据本申请实施例的显示模组100的制造方法，由于是在保护层3上涂覆防水胶，因此能较好地满足显示模组100中密封层4的结构形式需求，而且涂布方法简单，便于实现。
