本申请属于通信技术领域，具体涉及一种显示模组及电子设备。
背景技术
随着无线通信技术日新月异的发展，特别是随着5G的商用，无线通信系统的应用场景越来越丰富，从而对无线通信系统关键部件之一的天线的要求越来越高。一方面，在一些应用场景中，天线需要具有共形性，隐蔽性，安全性以便集成汽车，智能穿戴，智能家居等无线产品上，另一方面，随着无线通信系统的传输速率越来越高，通信容量越来越大，以至于载波频率越来越高，而载波频率越来越高带来的路径损耗越来越大，需要阵列天线提高增益克服路径损耗的影响，而为了高增益同时又能波束扫描或者波束赋形(beamforming)，需要采用相控阵列天线(phased antenna array)技术，从而需要在有限的空间内集成越来越多的天线。

具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是 全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的显示模组进行详细地说明。
本申请实施例的显示模组应用于电子设备，如用户设备(User Equipment，UE)，具体可以指接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备。
如图1-图5所示，本申请实施例的一种显示模组，包括：
显示面板2、盖板3以及柔性电路板1；
其中，所述柔性电路板1包括缝隙天线单元4，所述缝隙天线单元4设置于所述显示面板2和盖板3之间；
且所述缝隙天线单元4在所述显示面板2的正投影位于所述显示面板2的边缘区域。
如此，本申请实施例的显示模组，不仅包括显示面板2和盖板3，还包括柔性电路板1，而该柔性电路板1包括缝隙天线单元4，该缝隙天线单元4设置于显示面板2和盖板3之间，且该缝隙天线单元4在显示面板2的正投影位于该显示面板2的边缘区域，从而无需单独设置天线模组。并且，盖板一般为玻璃盖板，利用玻璃盖板具有较高介电常数，能够缩小天线单元的尺 寸，有效节省了空间。
此外，该实施例中，可选地，所述缝隙天线单元4位于所述柔性电路板1的第一区域101，包括：
设于所述柔性电路板1上的缝隙开孔402，围绕所述缝隙开孔402的过孔403，以及设置于所述缝隙开孔402一侧的馈电结构401。
即，利用该柔性电路板1上的第一区域101，制作该缝隙天线单元4，包括馈电结构401、缝隙开孔402以及过孔403，从而无需在柔性电路板上额外设置天线模组。由于该缝隙天线单元4的尺寸较小，其所处第一区域101能够实现在显示面板2所在平面的正投影位于净空区，而该净空区处于边缘区域，是不包括金属材质的结构或器件的，仅具有玻璃或塑胶介质等材质结构或器件。如此，显示模组安装到电子设备的时候，缝隙天线单元4构成的SIW(基片集成波导)缝隙天线，其自身结构是一个封闭的金属腔，利用屏幕的净空去辐射，对周围的金属环境的影响不敏感，从而对电子设备的结构和外观设计适应度高。
可选地，所述第一区域101对应的柔性电路板1包括：
层叠设置的第一金属地102、电路基板103和第二金属地104；
其中，所述缝隙开孔402位于靠近所述盖板3的第一金属地102上；
所述过孔403电连接所述第一金属地102和所述第二金属地104。
这样，围绕缝隙开孔402的过孔403，可实现金属化过孔，连接上下层金属地，从而由缝隙天线单元4的自身结构构建了一个金属腔体，通过缝隙开孔402进行辐射。
该实施例中，可选地，柔性电路板1的第一金属地102和第二金属地104所采用的金属为铜，电路基板103为FPC(柔性电路板)基板。其中，所述FPC基板的介电常数能够实现但不限于2.2，可根据要求灵活选择FPC基板。
可选地，所述缝隙开孔402为矩形开孔。
当然，缝隙开孔的形状不限于矩形，也能够根据要求灵活设置。
另外，该实施例中，可选地，所述第一金属地102上设置有至少两个开口，所述至少两个开口形成阻抗匹配结构404；
所述馈电结构401为相邻两个开口间的微带馈线。
其中，微带馈线是从SIW缝隙天线的腔体一端引出，延伸到屏幕的绑定(bonding)区。但是，除采用微带馈线进行馈电之外，实际中还可根据需要灵活采用其他馈电形式，如同轴馈电、共面波导馈电等。
且阻抗匹配结构也不限于图3所示的矩形开口，还可以采用其他匹配形式，如开圆形槽、打接地过孔等等，在此不再赘述。
可选地，所述缝隙天线单元4为毫米波天线。
具体地，缝隙天线单元4为SIW缝隙缝隙天线单元，由于其尺寸较小，如图3所示，在第一区域101内可以制作4个SIW缝隙天线单元。
当然，柔性电路板1上的缝隙天线单元4的数量还可以为其他值，根据天线所需实现功能灵活设计。
该实施例中，缝隙天线单元4的缝隙开孔402的缝隙宽度可以为0.1mm，长度为1.2mm，或者其他值等等。可选地，缝隙开孔402的大小可以由工作频率下二分之一介质波长确定。
可选地，如图3所示，所述柔性电路板1上设置有与所述馈电结构401电连接的射频集成电路5。
这里，射频集成电路5与该馈电结构401通过传输线6电连接，构成天线组件7。以SIW缝隙天线单元为例，微带馈线从SIW缝隙天线的腔体一端引出，通过FPC上的传输线转接出来，连接到RFIC(射频集成电路)的pin脚。其中，FPC上的传输线需要做阻抗控制。
可选地，所述柔性电路板1上还设置有射频集成电路5，屏幕集成电路8，以及所述射频集成电路5和所述屏幕集成电路8共用的连接器9。
连接器9设置在柔性电路板1的末端，通过该连接器9能够实现把屏幕管控以及天线相关的信号传输到主板上，而共用连接器进一步节省了空间。
当然，屏幕集成电路8也可通过未包括缝隙天线单元的另一柔性电路板实现，而制作有缝隙天线单元的柔性电路板，实现为如图5所示在显示面板2上端的柔性电路板1，此时，该柔性电路板1的连接器9仅用于将天线相关的信号传输到主板。
考虑到显示屏幕的触控需求，在该实施例中，可选地，所述显示模组还包括：
设置于所述显示面板靠近盖板一侧的偏光片和触控层；
所述缝隙天线单元设置于所述偏光片和所述盖板之间，或者，所述偏光片与所述触控层之间。
并且，对应于触控处理，还需要设置有触控集成电路的柔性电路板。可选地，如图2所示，所述柔性电路板1上还设置有触控集成电路10。该触控集成电路10与射频集成电路5、屏幕集成电路8共用连接器9。当然，触控集成电路也可不与射频集成电路设置在同一柔性电路板上，在此不再赘述。
而设置了触控集成电路10、射频集成电路5、屏幕集成电路8的柔性电路板1上，将通过屏幕信号线、触控控制线、电源线、天线馈线等承载信号及电源。
另外，该实施例中，可选地，所述柔性电路板1的数量为两个，且相对设置于所述显示面板2两端的边缘区域。
如图5所示，在显示面板2上端和下端的边缘区域均设置了所述柔性电路板1，这样，可以在用户手持安装该显示模组的电子设备，影响下端柔性电路板1的缝隙天线单元的传输质量的情况下，自动切换到上端柔性电路板1的缝隙天线单元工作。当然，也可以由下端的缝隙天线单元切换到上端缝隙天线单元。此外，还可以提升缝隙天线单元的空间覆盖范围，如累积分布函数(Cumulative Distribution Function，CDF)指标。
图6为本申请实施例中毫米波的SIW缝隙天线的反射系数示意图，图7为本实施例中毫米波的SIW缝隙天线的效率图。由图6可以看出以-10dB算，本实施例中毫米波SIW缝隙天线能够覆盖57.28GHz-62.94GHz；以-6dB算，本实施例中毫米波SIW缝隙天线能够覆盖55.05Hz-62.45GHz。由图7可以看出，本实施例中毫米波SIW缝隙天线在52-68GHz的带宽内的总效率大于-2dB，辐射性能良好。图8为本实施例中毫米波SIW缝隙天线在60GHz时的辐射方向图，可以看出本实施例中天线的辐射方向图朝向屏幕侧，满足设计要求。
本申请实施例还提供一种电子设备，包括如上所述的显示模组。
该电子设备承载所述显示模组的前壳或者中框可以为金属，因为缝隙天线单元采用SIW缝隙天线结构，其自身结构是一个封闭的金属腔，并利用屏幕的净空去辐射，所以其对周围的金属环境的影响不敏感，从而对电子设备 的结构和外观设计适应度高。
电子设备能够实现图1至图8的显示模组实施例中电子设备实现的各个过程，为避免重复，这里不再赘述。
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。此外，需要指出的是，本申请实施方式中的方法和装置的范围不限按示出或讨论的顺序来执行功能，还可包括根据所涉及的功能按基本同时的方式或按相反的顺序来执行功能，例如，可以按不同于所描述的次序来执行所描述的方法，并且还可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
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，本申请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)执行本申请各个实施例所述的方法。
上面结合附图对本申请的实施例进行了描述，但是本申请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申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
