具体实施方式
随着显示技术及无线通信技术的发展，对无线通信设备的通讯性能要求越来越高。智能反射表面(英文全称：Intelligent Reflecting Surface；英文简称：IRS)是现今获广大关注与研究投入的重要通信设计，因其可藉由调控此表面上多个反射单元上电气信号的幅值(amplitude)与相位(phase)(即通过改变反射单元的电气负载)改变来自无线讯号源入射的反射波束方向，如可将此反射波束维持一个或分成多个反射波束而导向集中至一个或多个通讯目标的方向，故有助无线通信质量的显著提升。而IRS的位置可布设于建筑物的内墙或外观壁上。
IRS一般是由三层结构组成，即表层是反射单元，反射单元为导体结构并用于反射无线信号。反射单元下是金属板，例如铜板用于遮挡并反射无线信号。金属板背离反射单元的一侧设置有控制电路板，控制电路板上的控制电路与反射单元电气连接并用于调控各反射单元的信号幅度及相位，进而控制反射波束的方向和数目，而此三层结构皆是非人眼视觉透明的结构，故造成IRS也是非人眼视觉透明。
为了提高显示屏的通讯性能，本申请将IRS集成于显示屏上。然而，如上所述，目前的IRS基本皆为非人眼视觉透明的设计，故会对其布设的背景(如墙面)进行遮挡，而不利原本背景的外观设计及一致性，故会限制IRS应用的场景与范围。
为了解决上述问题，提出了本申请，为了更好地理解本申请，下面结合图1至图33对本申请实施例的显示屏和无线通信设备进行详细描述。

可选的，功能层100和遮挡层200为透明结构层，例如功能层100和遮挡层200的综合透光率大于50％。可选的，发射层的透光率大于60％、70％、80％甚至90％。可选的，遮挡层200的透光率大于60％、70％、80％甚至90％。
在本申请实施例提供的显示屏10，功能层100包括反射单元110，反射单元110能够反射无线信号，例如反射单元110能够将无线信号反射至通讯目标，以提高显示屏10的无线通信质量。遮挡层200设置于功能层100的背离显示屏10显示面的一侧，一方面遮挡层200能够遮挡无线信号，使得无线信号在功能层100反射，另一方面也改善无线信号进入显示屏10内部影响显示屏10其他零部件的运行；功能层100和遮挡层200的综合透光率大于50％，能够降低功能层100和遮挡层200对显示屏10显示效果的影响。因此，本申请实施例通过在显示屏10内设置透光率较高的功能层100和遮挡层200，能够有效提高显示屏10的无线通信性能。
可选的，显示屏10可以为有机发光二极管显示屏10、液晶显示屏10或微发光二极管显示屏10。
可选的，各反射单元110均连接有至少一个调制电路620，且不同反射单元110连接的调制电路620不同，以通过调制电路620分别调节各反射单元110上电气信号的幅值和/或相位。

功能层100的个数设置方式有多种，例如，如图1所示，功能层100的个数为一个，一个功能层100内设置有阵列分布的两个以上的反射单元110。可选的，遮挡层200的个数为一个。
在另一些可选的实施例中，如图15所示，图15为一种显示屏10的局部放大图。功能层100的个数为两个以上，位于不同功能层100中的至少两个反射单元110在基板11上的正投影面积不同。可选的，图15中俯视图上显示相互套设的两个反射单元110位于两层不同的功能层100内。图15中仅示意出了一组至少部分交叠的反射单元110，至少部分交叠的反射单元110的个数可以为多组。
在这些可选的实施例中，通过设置两个以上的功能层100，并在不同的功能层100内设置尺寸不同的反射单元110，使得尺寸不同的反射单元110能够反射不同频段的无线信号，能够进一步提高显示屏10的无线通信性能。
可选的，同一功能层100内两个以上的反射单元110在基板11上的正投影面积相同，即同一功能层100内的两个以上的反射单元110的尺寸相同，使得同一功能层100内的两个以上的反射单元110能够反射同一频段的无线信号，进而增强对同一频段无线信号的反射能力。
在一些可选的实施例中，请继续参阅图15，当功能层100的个数为两个以上时，两个以上的功能层100包括第一功能层101和第二功能层102，即两个以上的功能层100中的一者为第一功能层101，另一者为第二功能层102。反射单元110包括位于第一功能层101的第一反射单元111和位于第二功能层102的第二反射单元112，其中，第一功能层101位于第二功能层102朝向显示屏10显示面的一侧，且第一反射单元111在基板11上的正投影面积小于第二反射单元112在基板11上的正投影面积。
在这些可选的实施例中，第一反射单元111位于第二反射单元112朝向显示屏10显示面的一侧，且第一反射单元111的尺寸小于第二反射单元112的尺寸，一方面，至少部分第二反射单元112没有被第一反射单元111遮挡，第二反射单元112也能够反射无线信号；另一方面，第一反射单元111的尺寸和第二反射单元112的尺寸不同，故可反射多频段的无线信号，以使显示屏10对于不同频段的无线信号皆能有调控反射信号的能力。
可选的，各第一反射单元111在基板11上的正投影和各第二反射单元112在基板11上的正投影至少部分交叠设置。以降低两个以上的反射单元110整体的分布面积。各第一反射单元111在基板11上的正投影和各第二反射单元112在基板11上的正投影至少部分交叠设置包括：第一反射单元111和第二反射单元112一一对应设置，且各第一反射单元111在基板11上的正投影和各第二反射单元112在基板11上的正投影至少部分交叠设置。或者，两个以上的第一反射单元111对应同一第二反射单元112设置，或者同一第一反射单元111对应两个以上的第二反射单元112设置，只要每一个第一反射单元111在基板11上的正投影均能够与至少一个第二反射单元112在基板11上的正投影至少部分交叠，每一个第二反射单元112在基板11上的正投影均能够与至少一个第一反射单元111在基板11上的正投影至少部分交叠即可。
可选的，如图15所示，至少部分连接线300设置于第一反射单元111和第二反射单元112的交叠区域并连接第一反射单元111和第二反射单元112。
在这些可选的实施例中，将至少部分连接线300设置于第一反射单元111和第二反射单元112 的交叠区域，使得连接线300沿显示屏10的厚度方向延伸即可同时连接第一反射单元111和第二反射单元112，能够简化连接线300的结构。
可选的，交叠区域在基板11上的正投影位于封装部12a在基板11上的正投影之外，以使得连接线300能够设置于封装部12a在基板11上的正投影之外。
可选的，如图15所示，第一反射单元111和第二反射单元112可以一一对应设置。或者，如图16所示，由于第一反射单元111的尺寸小于第二反射单元112的尺寸，两个以上的第一反射单元111可以和同一第二反射单元112对应设置。
在一些可选的实施例中，如图16所示，两个以上的第一反射单元111和同一第二反射单元112对应设置，相互对应的第二反射单元112和两个以上第一反射单元111中，两个以上的第一反射单元111在基板11上的正投影位于同一第二反射单元112在基板11上的正投影之内。图5中仅示意出了一个第二反射单元112，可选的，第二反射单元112的个数为多个，多个第二反射单元112间隔设置，各第二反射单元112朝向显示屏10显示面的一侧均设置有两个以上的第一反射单元111。
在这些可选的实施例中，由于第一反射单元111的尺寸较小，因此两个以上的第一反射单元111对应于同一第二反射单元112设置，能够增加第一反射单元111的布置个数，提高第一功能层101的无线通信性能。两个以上的第一反射单元111在基板11上的正投影位于同一第二反射单元112在基板11上的正投影之内，使得第一反射单元111和第二反射单元112的排布更加规律，便于制备成型。
可选的，如图17所示，相互对应的第二反射单元112和两个以上第一反射单元111中，两个以上的第一反射单元111在基板11的投影面积不同，使得对应于同一第二反射单元112的两个以上的第一反射单元111能够反射不同频段的无线信号，进一步提高显示屏10的无线通讯性能。
在另一些可选的实施例中，如图16所示，相互对应的第二反射单元112和两个以上第一反射单元111中，两个以上的第一反射单元111在基板11的投影面积也可以相同。
可选的，如图18和图19所示，第一反射单元111在基板11上的正投影形状和第二反射单元112在基板11上的正投影形状可以相同或不同。例如，第二反射单元112在基板11上的正投影形状呈矩形，第一反射单元111在基板11上的正投影形状可以呈矩形或圆形等。
可选的，当同一反射单元110连接于两个以上的控制电路610时，如图20所示，同一反射单元110连接有两个以上的第二连接线302，反射单元110通过各第二连接线302连接各控制电路610。当同一反射单元110连接有两个以上的第二连接线302时，两个以上的第二连接线302在同一反射单元110上间隔分布，以改善两个以上的第二连接线302之间的相互影响。
可选的，当同一反射单元110连接于两个以上的调制电路620时，同一反射单元110连接有两个以上的第一连接线301，反射单元110通过各第一连接线301连接各调制电路620。当同一反射单元110连接有两个以上的第一连接线301时，两个以上的第一连接线301在同一反射单元110上间隔分布，以改善两个以上的第一连接线301之间的相互影响。
在一些可选的实施例中，如图1所示，显示屏10还包括信号线层11a。反射单元110和第二连接线302可以同层设置并均位于信号线层11a，以简化显示屏10的结构。
如图21至图23所示，反射单元110设置于信号线层11a，第二连接线302设置于其他导电层，反射单元110和第二连接线302不同层设置，便于第二连接线302在其他导电层内自由布置。或者，第二连接线302设置于信号线层11a，反射单元110设置于其他导电层，便于第二连接线302在信号线层11a自由布置，反射单元110在其他导电层自由布置，反射单元110和第二连接线302的布置互不干扰。在图21和图23中，由于反射单元110和第二连接线302不同层设置，因此俯视图上能够观察到反射单元110而无法观察到第二连接线302。
可选的，第二连接线302可以布置于功能层100背离遮挡层200一侧的导电层内，例如第二连接线302设置于信号线层11a，信号线层11a可以位于功能层100背离遮挡层200的一侧。或者，如图22所示，第二连接线302可以布置于功能层100和遮挡层200之间的导电层内。或者，第二连接线302设置于信号线层11a，信号线层11a可以位于功能层100和遮挡层200之间。
信号线层11a的设置方式有多种，例如，如图1所示，信号线层11a包括网格状金属布线，至少部分金属布线复用为反射单元110和/或连接线300。网格状金属布线包括沿第一方向X延伸的第一信号线(图1中沿第一方向X延伸的灰色信号线)和沿第二方向Y延伸的第二信号线(图1中沿第二方向Y延伸的灰色信号线)，多条第一信号线和多条第二信号线交叉布置形成网格状。
如上所述，当部分金属布线复用为反射单元110和/或连接线300时，该部分金属布线与其他位置的金属布线相互绝缘，以避免相邻的反射单元110和/或连接线300短路连接。
可选的，如图5所示，网格金属布线的延伸方向与显示屏10的长度方向相交。网格金属布线的延伸方向可以为第一信号线的延伸方向，也可以为第二信号线的延伸方向。显示屏10包括第一侧边和第二侧边，两个第一侧边和两个第二侧边交替连接围合形成显示屏10。第一侧边的长度大于第二侧边的长度，第一侧边的延伸方向可以为显示屏10的长度方向。网格金属布线的延伸方向与显示屏10的长度方向相交，即第一信号线和/或第二信号线的延伸方向与第一侧边的延伸方向相交，能够降低网格状金属布线对显示屏10显示效果的影响。
在另一些可选的实施例中，如图6所示，显示屏10还包括透光导电层11b，透光导电层11b的 材料例如包括氧化铟锡等透光导电材料，以提高透光导电层11b的透光率。透光导电层11b具有透光率较高且能够导电的特性。
可选的，反射单元110、连接线300和遮挡层200中的至少一者设置于透光导电层11b，以提高反射单元110和遮挡层200的透光性能，降低反射单元110和遮挡层200对显示屏10显示效果的影响。
可选的，透光导电层11b包括层叠设置的第一导电层(图中未示出)和第二导电层(图中未示出)，反射单元110和连接线300中的至少一者设置于第一导电层，遮光层200设置于第二导电层。在这些可选的实施例中，连接线300和遮光层200均设置于透光导电层11b，且分别位于不同的导电层，一方面能够改善连接线300和遮光层200布置的相互影响，另一方面还能够保证反射单元110和遮挡层200的透光率。
可选的，当反射单元110和/或连接线300设置于透光导电层11b时，如图24所示，反射单元110可以连接有一连接线300(连接线300例如为第二连接线302)；或者，如图25所示，反射单元110可以连接有两个以上的连接线300(连接线300例如为第二连接线302)。
在一些可选的实施例中，如图26所示，基板11包括阵列基板11c和公共电极层11d，公共电极层11d位于阵列基板11cc朝向显示屏10显示面的一侧，公共电极层11d复用为遮挡层200。使得遮挡层200能够复用显示屏10原有的层结构，能够简化显示屏10的结构。
可选的，阵列基板11c包括衬底和设置于衬底的驱动电路。可选的基板11上设置有平坦化层、像素电极层、像素定义层。像素电极层包括在平坦化层上阵列分布的多个像素电极，像素定义层位于像素电极层背离平坦化层的一侧，像素定义层包括像素限定部和由像素限定部围合形成的像素开口，像素开口内可以设置发光单元11e。公共电极层11d设置于像素限定部和发光单元11e背离平坦化层的一侧。
可选的，公共电极层11d背离像素定义层的一侧还设置有封装层12和触控层，反射单元110可以设置于触控层内，以进一步简化显示屏10的结构。
如图26至图33所示，本申请第二方面的实施例还提供一种无线通信设备，包括上述任一第一方面的显示屏10。由于本申请的无线通信设备包括上述实施例的显示屏10，因此本申请实施例的无线通信设备具有上述任一实施方式的显示屏10的有益效果，在此不再赘述。
本申请实施例中的无线通信设备包括但不限于手机、无线穿戴设备、个人数字助理(Personal Digital Assistant，简称：PDA)、平板电脑、电子书、电视机、门禁、智能固定电话、控制台、电子看板、透明衬底看板等具有显示功能的设备。
如图26至图30所示，显示屏10的反射单元110和/或第二连接线302可以设置于网格状金属布线层中，图30和图28不同之处在于网格状金属布线层中的金属走线延伸方向不同。或者，如图31所示，显示屏10的反射单元110和/或第二连接线302可以设置于透光导电层11b中。
在一些可选的实施例中，如图28和图33所示，无线通信设备还包括电路板500，电路板500可以为柔性电路板，控制电路610设置于电路板500，电路板500弯折设置，以使控制电路610位于显示屏10的非显示侧。以提高无线通信设备的显示面积占比。图28为电路板500在展开状态下的结构示意图。图33为电路板500在折叠状态下的结构示意图。
