技术领域
本申请涉及显示技术领域，具体涉及一种显示面板及显示装置。
背景技术
天线是智能手机等智能终端设备的重要部件，随着移动通讯技术的蓬勃发展，5G通讯技术逐渐普及，然而5G通讯技术的普及导致手机天线数量大幅增加，而手机边框越来越窄，且手机厚度变薄，内部间被压缩，使得手机内部放置天线的空间严重不足，进而导致手机天线通讯效率较低，手机天线对工程师带来的挑战日益剧增。
发明内容
本申请提供一种显示面板及显示装置，以解决手机等智能终端设备通信效率较低的问题。

具体实施方式
天线是智能终端中重要的组成部分，通过天线实现智能终端的通信功能。在设置天线时需要保证一定的净空区域，以避免其它元器件影响天线的通信效果。而5G通讯技术所需的天线数量较多，这与智能手机等智能 终端的设计日渐要求的轻、薄、小及美观背道而驰。手机内部天线净空区域不足，手机通信尤其是高频通信容易受到干扰，影响通信效果。因此如何实现较小的手机能够布置下较多的天线，以提高手机等智能终端的通信效率是一个难点。
基于此，本申请实施例提供一种显示面板及显示装置，能够解决智能终端设备内部放置天线的空间不足的技术问题。
参照图1至图7，显示面板100具有第一显示区PL和第二显示区BE，第二显示区BE包括相邻设置的第一区域BE1和第二区域BE2，第一区域BE1内设有第一天线120，第二区域BE2内设置有第二天线130。显示面板100还包括设置在第一显示区PL与第二区域BE2内的触控电极。
具体地，根据显示面板100的形状的不同，第一显示区PL和第二显示区BE的相对位置以及各自的形状也不尽相同。
示例性地，第一显示区PL可以呈矩形、圆形或者椭圆形等，第二显示区BE可以设置在第一显示区PL的周侧，也可以设置在第一显示区PL的内部，可以根据需要进行选取。在第二显示区BE设置在第一显示区PL的周侧时，第二显示区BE可以环绕第一显示区PL的全部设置，也可以环绕设置在第一显示区PL周侧的一部分。可选地，当第一显示区PL呈矩形时，第二显示区BE可以设置在当第一显示区PL的一侧或者多侧。
可选地，第一显示区PL可以呈平面，也可以呈曲面设置，第二显示区BE也可以呈平面或者曲面设置，可以根据实际需求选取第一显示区PL和第二显示区BE的具体形状。
一些实施例中，如图1所示，第一显示区PL和第二显示区BE也可以均呈曲面，则对应的显示面板100应用于显示装置时，显示装置为曲面显示装置或者柔性显示装置。另一些实施例中，如图2所示，第一显示区PL和第二显示区BE可以均呈平面，则对应的显示面板100应用于显示装置时，显示装置为平面显示装置。有一些实施例中，如图4所示，第一显示区PL呈平面，第二显示区BE呈曲面，比如由第一显示区PL的边缘弯折而成，如此设置，依然能够实现本申请的发明目的。
可选地，第一显示区PL可以是可折叠的，也可以是不可折叠的，如 图3示出了显示面板100的第一显示区PL为可折叠的示例。
显示面板100可以是有机发光二极管(Organic Light Emitting Diode，OLED)显示面板100，也可以是液晶显示面板100(Liquid Crystal Display，LCD)。
第一天线120可以为图形化结构，第二天线130也可以为图形化结构，可以根据实际需求设置第一天线120和第二天线130的图形，本申请对此不作限定。
在第二区域BE2内设置触控电极110a，即设置第二区域BE2具有触控功能。第二区域BE2的触控形式可以是自电容形式，也可以是互电容形式，不同的触控形式对应触控电极110a的不同结构形式。
参照图6，在一些实施例中，第二区域BE2的触控形式为互电容形式，此时，触控电极110a可以是多个同层设置、且呈阵列分布的电极块，同一矩阵行或者同一矩阵列中的触控电极110a相互电连接。
在另一些实施例中，第二区域BE2的触控形式为自电容形式，此时，触控电极110a包括绝缘设置的触控驱动电极和触控感应电极，触控驱动电极和触控感应电极中的一者沿行方向延伸，另一者沿列方向延伸，二者交叉的位置可以产生电容。
参照图6，在第二显示区BE的第二区域BE2同时设置有第二天线130和触控电极110a，即第二区域BE2在具备天线功能的同时，还具有触控功能。而在第二显示区BE的第一区域BE1仅设置第一天线120，如此，第一区域BE1仅具有天线功能，而不具有触控功能，可以降低对第一区域BE1产生误触而影响第一区域BE1的天线功能的风险，也使得所述第一区域BE1具有足够的空间进行第一天线120的布设。
需要说明的是，第二区域BE2对天线信号和触控信号进行采样时，可以同时进行采样，也可以交替采样。在一些实施例中，为了避免两种信号的相互干扰，可以采用时间分割复用法对第二区域BE2中的天线信号和触控信号进行信号采样。
具体地，可以对天线信号和触控信号按照相同的时间周期进行采用，只要采样脉冲宽度足够窄，在同种信号的两个采样值之间就会留有一定的 时间空隙。如果另外一种信号的采样时刻正好在该时间空隙内，则两种信号的采样值在时间上将不会发生重叠。可选地，天线信号和触控信号的采用周期可以设定在1μs～10ms之间的任意数值，可以根据具体需求进行选取。通过采用此种控制方法对天线信号和触控信号进行采样，可以使第二天线130和触控电极110a在共用同一空间，以实现第二区域BE2兼具有天线功能和触控功能的同时，由于二者交错进行信号采集，不会对彼此产生信号干扰。
将第一天线120设置于第二显示区BE的第一区域BE1，可以根据实际情况设置第一区域BE1在显示面板100的位置，以实现显示面板100较高的屏占比，且第一区域BE1仅设置有第一天线120，使其仅具有接收或者发送信号的功能，而不具备触控功能，如此设置，为第一天线120提供足够的净空区间，可以提高第一天线120的通信效率，且降低误触的风险。另外，由于第一区域BE1仅设置有第一天线120，而没有设置触控电极110a，因此，不同于第二天线130和触控电极110a交错地进行天线信号和触控信号的采集，第一天线120可以持续性地进行信息的接收和发送，即第一天线120可以持续地实现天线的功能。
可选地，所述第一天线120与第二天线130可以均为毫米波天线；第一天线120可以为主天线，第二天线130可以为辅助天线，以增强第一天线120的信号；当第二天线130复用为触控电极110a时，第一天线120即主天线也能独立进行通信。
本申请实施例提供的显示面板100，通过将第一天线120设置在第二显示区BE的第一区域BE1，第二天线130设置在第二显示区BE的第二区域BE2，且第二区域BE2同时设置有触控电极110a，即将天线集成在显示面板100的第二显示区BE，第二显示区BE既能够实现显示功能，又能够实现天线功能，无需单独设置天线区域，有利于实现显示面板100的轻薄化与高屏占比设置。其中，第一区域BE1仅设置第一天线120，保证第一天线120的布设空间，还能降低对第一区域BE1误触而影响第一天线120功能的风险。而第二区域BE2既设置第二天线130又设置有触控电极110a，即第二区域BE2既可以实现天线功能，也可以实现触控功能，不影 响第二区域BE2的触控功能的同时，合理利用第二区域BE2进行更好地天线集成设置，提高显示面板100的通信效率。
第二显示区BE内的第一区域BE1和第二区域BE2的数量可以根据需求进行选取，可以分别是一个，也可以分别是多个，多个第一区域BE1或者多个第二区域BE2交错分布。多个第一区域BE1的形状和大小可以相同，也可以不相同，根据实际需要进行设置。
在一些实施例中，第二显示区BE设置成条形且沿第一显示区PL的边缘延伸设置。
具体地，根据第一显示区PL的边缘形状的不同，第二显示区BE可以呈不同形状的条形。比如，第一显示区PL的边缘呈圆弧形，则第二显示区BE呈圆弧状的条形，第二显示区PL的边缘呈直线形，则第二显示区BE呈直条形，即第二显示区BE呈线性延伸。
可选地，第二显示区BE可以呈平面，也可以呈曲面。
将第二显示区BE设置在第一显示区PL的边缘，便于在第二显示区BE内集成第一天线120和第二天线130，且利用呈条形的第二显示区BE设置第一天线120和第二天线130，使得第二显示区BE在具有天线功能的同时，兼具有显示功能，便于实现显示面板的高屏占比。
在一些实施例中，在第二显示区BE的延伸方向X上，第一区域BE1位于相应的第二显示区BE的中间位置，至少两个第二区域BE2分设在第一区域BE1的两侧。
示例性地，可以设置一个第一区域BE1和两个第二区域BE2，两个第二区域BE2分别位于第一区域BE1沿延伸方向X的两侧。也可以设置两个第一区域BE1，而设置三个第二区域BE2，两个第一区域BE1和三个第二区域BE2沿延伸方向X交错分布。当然也可以设置更多个第一区域BE1和第二区域BE2，可以根据具体设置需求进行选取。
如此设置，可以使得第二显示区BE沿延伸方向X两端为第二区域BE2，更便于操作者对第二显示区BE进行触控操作。
在一些可选的实施方式中，第二显示区BE的延伸长度为L1，第一区域BE1沿第二显示区BE的延伸方向X的长度为L2，其中，30％≤L2/L1 ≤50％。
具体地，参照图4，第二显示区BE具有一个第一区域BE1和位于第一区域BE1沿延伸方向X两端的两个第二区域BE2。由于第一区域BE1仅具有天线功能，而没有设置有触控功能或者触控相关器件，而第二区域BE2具有触控功能，由于不需要对第一区域BE1进行触控操作，因此将第一区域BE1设置在第二显示区BE靠近中间的位置，进一步降低对第一区域BE1误触的风险。同时第二区域BE2设置在第二显示区BE沿自身延伸方向X的两端，由于第二区域BE2具有触控功能，更便于操作者对第二区域BE2进行触控操作。
示例性地，第一区域BE1位于第二显示区BE沿延伸方向X的正中间，两端的第二区域BE2沿延伸方向X的延伸长度相同。
L2/L1可以为30％、35％、40％、45％或者50％等，示例性地，可以设置第一区域BE1和两端的第二区域BE2对第二显示区BE三等分。如此设置，可以保证第二显示区BE具有足够的设置第一天线120的第一区域BE1的空间，降低操作者对第一区域BE1造成误触的风险，同时由于第二区域BE2具有触控功能时，进一步便于操作者对第二显示区BE的第二区域BE2进行触控操作。
第一天线120与第二天线130和触控电极110a可以同层设置，也可以不同层设置，可以根据具体需求进行选取。示例性地，可以设置第一天线120和第二天线130同层设置，而与触控电极110a不同层设置。
在一些实施例中，第二天线130与触控电极110a同层设置。
具体地，参阅图6和图7，显示面板100包括衬底140和设置于衬底140一侧的触控层110，衬底140可以包括发光结构，触控电极110a设置于触控层110，第二天线130也设置于触控层110，参阅图9和图10，示出了触控电极110a和第二天线130同层设置的实施例。
根据第二区域BE2的触控形式不同，显示面板100可以包括一层或者多层触控层110，第二区域BE2内的触控电极110a可以设置在两层或者更多层触控层110中，第二天线130可以设置在触控层110中的任意一个膜层中，且与该膜层的触控电极110a或引线间隔设置，以降低彼此之间的信 号干扰。
通过设置第二天线130与触控电极110a同层设置，可以利用触控层110中对应的触控电极110a之间的间隙设置第二天线130，在实现第二区域BE2的触控功能或者为实现触控功能提供电信号以及天线功能的同时，无需对第二天线130单独设置一个膜层，有效地降低了显示面板100的厚度。
示例性地，第二区域BE2的触控形式为自电容形式时，触控层110包括绝缘设置的触控驱动电极层和触控感应电极层，第二天线130可以设置于触控驱动电极层，也可以设置于触控感应电极层。
可选地，第二区域BE2的触控形式也可以为互电容形式，此时，触控层110可以包括触控电极层和桥接层，其中触控电极110a设置于触控电极层，此时第二天线130可以设置于触控电极层。
通过上述设置，均可以实现第二区域BE2的触控功能和天线功能，同时降低显示面板100的厚度。
在第二天线130与触控电极110a同层设置的实施例中，第一天线120与第二天线130和触控电极110a可以同层设置，也可以不同层设置，均可以实现第一区域BE1的天线功能。
在一些实施例中，第一天线120与触控电极110a同层设置。也即是说，第一天线120、第二天线130以及触控电极110a均设置于触控层110，进一步降低显示面板100的厚度。
具体地，触控电极110a设置在第一显示区PL以及设置在第二区域BE2，第一天线120和第二天线130设置在第二显示区BE，则第二显示区BE的膜层与第一显示区PL对应的膜层可以一起成型。如此设置，可以进一步降低显示显示面板100的厚度。
在另一些实施例中，显示面板100包括层叠设置的触控层110和天线层，触控电极110a设置于触控层，第二天线130设置于天线层。
也就是说，触控电极110a和第二天线130不同层设置，可以位于相邻的膜层，也可以间隔一个或者多个膜层。
将触控电极110a和第二天线130设置在不同的膜层，可以降低显示面 板100的加工难度，降低第二天线130和触控电极110a短路的风险。
在一些实施例中，如图8所示，所述第一天线120包括至少一个第一天线单元121，所述第二天线130包括一个或多个第二天线单元131。
可选地，第二区域BE2内的第二天线单元131与触控电极110a在结构上可以复用，也可以分别设置二者的结构。
具体地，所述第一天线120可以通过第一走线171连接至第一天线端子173。
在一些实施例中，第二区域BE2内的至少部分触控电极110a复用为第二天线单元131。
复用为第二天线单元131的触控电极110a的结构可以通过第二走线172连接至第二天线端子174。由于第二区域BE2内的触控信号和天线信号可以通过时间分割复用法分开取样，所以，触控电极110a和第二天线单元131复用结构，不会造成信号干扰，且二者复用结构，可以进一步简化显示面板100的结构。可选地，显示面板100还包括触控绑定端子，所述触控电极110a通过触控走线连接至触控绑定端子，具体不再详述。
在另一些实施例中，如图9和图10所示，第二天线130包括第二天线单元131，第二天线单元131与触控电极110a间隔设置，具体是指第二天线单元131与构成触控电极110a的导电材料相互间隔且绝缘设置。
示例性地，显示面板100的触控形式为互容式，多个触控电极110a同层阵列分布，同一矩阵行或者同一矩阵列的触控电极110a相互电连接。其一所述第二天线单元131或多个第二天线单元131电连接形成天线图案，以实现相应的天线功能。第二天线单元131与触控电极110a间隔设置，则二者不会相互导电，进而不会对彼此产生信号干扰。如此设置，在实现第二区域BE2兼具有触控功能和天线功能的同时，进一步降低显示面板100的厚度。
第二天线单元131可以设置在相邻两触控电极110a之间，可以设置第二天线单元131围绕触控电极110a设置，或者触控电极110a围绕第二天线单元131设置。
在一些可选的实施例中，请继续参阅图9和图10，至少部分触控电极 110a围绕第二天线单元131设置。
具体地，第二天线单元131分布呈一行或者一列，或者第二天线单元131呈矩阵分布，至少部分触控电极110a围绕第二天线单元131设置，就是说所述第二天线单元131设置在相应的触控电极110a内部。
设置部分触控电极110a围绕第二天线单元131设置，在降低显示面板100厚度的同时，不会扰乱触控电极110a的分布图案，以保证第二区域BE2的触控灵敏度。
第一天线120和第二天线130可以分别为长波天线、中波天线、短波天线、超短波天线或者微波天线等，可以根据实际需求进行选取。
在一些实施例中，第一天线120与第二天线130均为毫米波天线，第一天线120为主天线，第二天线130为辅助天线并用以增强第一天线的信号。
具体地，第一天线120和第二天线130实现的功能相同，第二天线130可以增益第一天线120的信号传递的效率，以使对应的天线功能具有更好的效果。
在另一些实施例中，第一天线120和第二天线130可以均为非毫米波天线，所述第一天线120、第二天线130具体可构成蓝牙天线、无线网络通信技术(Wi-Fi)天线、全球定位系统(Global Positioning System，GPS)天线、近场通信(Near Field Communication，NFC)天线、激光直接成型技术(Laser-Direct-structuring，LDS)天线中的一种或两种及以上。
在一些实施例中，第一天线120为NFC天线。即通过第一天线120实现显示装置的近场通信功能。
第二天线130可以与第一天线120的种类相同，也可以不相同，可以根据实际需求设置。
在一些实施例中，第二天线130为NFC天线。即通过第二天线130增强显示面板100的近场通信信号，增益显示面板100的近场通信的效率。
在一些实施例中，显示面板100还包括天线层，第一天线120和/或第二天线130设置在天线层。
也就是说，第一天线120和第二天线130的至少一者设置在天线层，另一者设置在其它膜层，或者第一天线120和第二天线130均设置在天线层。
天线层可以为一层也可以为多层，天线层为一层时，可以第一天线120和第二天线130均设置在天线层，也可以其中一者设置在天线层。天线层为多层时，第一天线120和第二天线130可以设置在不同的天线层，也可以设置在同一天线层。
设置天线层是为了便于对应的第一天线120和/或第二天线130的设置，降低显示面板100的加工难度。
在一些实施例中，如图4和图11所示，显示面板100包括衬底140、依次设置在衬底140一侧的发光层与偏光层150，第一天线120设置于偏光层150。
也就是说，将第一天线120集成在偏光层150，而无需单独设置一个膜层，进一步降低显示面板100的厚度。且第一天线120设置在偏光层150的方案，可以降低第一天线120与其它膜层相关元器件之间的信号干扰，提高显示面板100的通信效率。
在第一天线120设置于偏光层150的实施例中，第二天线130可以设置于偏光层150，也可以设置于其它膜层，可以根据实际需求设置。
在一些实施例中，第二天线130设置于偏光层150。如此第一天线120和第二天线130集成在同一膜层，进一步降低显示面板100的厚度。
在一些实施例中，请继续参阅图4和图11，显示面板100包括衬底140、依次设置在衬底140一侧的发光层与封装层160，第一天线120设置于封装层160。
也就是说，除了将第一天线120集成偏光层150外，还可以将第一天线120集成在封装层160，而无需单独设置一个膜层，依然可以降低显示面板100的厚度。且第一天线120设置在封装层160的方案，依然可以降低第一天线120与其它膜层相关元器件之间的信号干扰，提高显示面板100的通信效率。
在一些实施例中，第二天线130设置于封装层160。如此，依然可以 降低显示面板100的膜层厚度。
在显示面板100既设置有偏光层150又设置有封装层160的实施例中，偏光层150设置于衬底140的一侧，封装层160设置在偏光层150远离衬底140的一侧。此时，第一天线120和第二天线130可以设置在封装层160，与可以设置在偏光层150，或者其中一者设置在封装层160，另一者设置在偏光层150，可以根据实际需求选取。
偏光层150设置于衬底140的一侧，并不是指偏光层150直接设置在衬底140表面，偏光层150和衬底140之间可以设置有其它膜层。封装层160和偏光层150之间也可以设置有其它膜层。
在一些实施例中，请继续参阅图4和图11，显示面板100包括依次设置于衬底140一侧的阵列基板170与发光层，第一天线120和/或第二天线130设置于阵列基板170。也就是说将第一天线120和第二天线130中的至少一者集成在显示面板100的阵列基板170内，如此设置，依然能够达到降低显示面板100厚度的目的。
在一些实施例中，阵列基板170包括金属层，第一天线120和/或第二天线130设置于金属层。即第一天线120和第二天线130中的至少一者设置于金属层。阵列基板170包括至少两层金属层，第一天线120和第二天线130可设置在同一金属层或不同的金属层。
根据显示面板100的结构型式的不同，显示面板100可以设置一个第二显示区BE，也可以设置多个第二显示区BE。显示面板100设置多个第二显示区BE的实施例中，多个第二显示区BE可以相互邻接，也可以间隔设置，示例性地，显示面板100的两个第二显示区BE设置在第一显示区PL相对的两侧，即两个第二显示区BE平行设置。
在显示面板100设置有多个第二显示区BE的实施例中，可以在每一个第二显示区BE均设置有第一天线120和第二天线130，也可以在部分第二显示区BE设置第一天线120和第二天线130，可以根据具体需求进行选取。
在一些实施例中，显示面板100包括至少两个第二显示区BE，第一区域BE1及第二区域BE2设置在至少其中一个第二显示区BE。
具体地，至少其中一个第二显示区BE包括第一区域BE1和第二区域BE2，第一区域BE1设置有第一天线120，第二区域BE2设置有第二天线130和触控电极110a。其它第二显示区BE可以仅具有显示功能，也可以同时具备显示功能和触控功能。
通过在至少部一个第二显示区BE内设置第一天线120和第二天线130，可以根据实际需要将第一天线120和第二天线130设置在多个第二显示区BE内，为第一天线120和第二天线130的设置提供足够的空间，进一步提高显示面板100的通信效率。
如图4所示，在一些实施例中，第一显示区PL为平面显示区，第二显示区BE为弯折显示区。
具体地，弯折显示区可以与平面显示区一体成型后，由平面显示区的边缘弯折形成，将第一天线120和第二天线130设置在弯折显示区，利用弯折显示区的位置分别设置第一天线120和第二天线130，而不必占用平面显示区或者非显示区的位置空间，有利于提高显示面板100的屏占比。
在一些实施例中，显示面板100包括至少两个弯折显示区，第一区域BE1及第二区域BE2设置在至少其中一个弯折显示区。也就是说，第一区域BE1和第二区域BE2可以形成在一个弯折显示区，当然，也可以分别形成在不同的弯折显示区，如此，便于根据实际需求合理设置第一天线120和第二天线130的位置。
根据本申请实施例提供的显示装置，包括上述任意一实施例提供的显示面板100。
本申请实施例提供的显示装置，由于采用了上述任意一实施例提供的显示面板100，因而具有同样的技术效果，在此不再赘述。
