本申请实施例提供一种显示装置，包括显示面板、射频集成电路(Radio Frequency IC，RFIC)芯片1以及触控集成电路(Integrated Circuit，IC)芯片2；
如图1所示，显示装置还包括：设置于显示面板上的多个感应电极组，多个感应电极组呈行列交叉排布，沿行方向排布的感应电极组与沿列方向排布的感应电极组之间绝缘设置；其中，至少部分行和/或列排布的感应电极组为第一感应电极组，所述第一感应电极组复用为天线，通过频分器3分别与 所述射频集成电路RFIC芯片1和所述触控集成电路芯片2连接。
具体地，感应电极组为多个，呈行列交叉排布，多个感应电极组中的部分或全部复用为天线，需要与所述频分器3连接。如图2所示，以感应电极组共有14组为例，每一组中均有多个电极块，沿行方向排列或者沿列方向排列，其中1-8组为呈行方向排列，9-14组为呈列方向排列。其中，第1-3组以及第12-14组的感应电极组为第一感应电极组，每一组感应电极组均通过一个频分器3分别与RFIC芯片1和所述触控IC芯片2连接。需要说明的是，图1和图2中交叉排列的多个所述感应电极组中，沿行方向排列的感应电极组与沿列方向排列的感应电极组之间不相连。
需要说明的是，第一感应电极组可以为沿行方向排布的感应电极组，也可以为沿列方向排布的感应电极组，也可以是行方向和列方向排布的部分感应电极组。第一感应电极组复用为天线。不需要额外在触控屏幕上插入一层天线层，仅仅与感应电极组连接频分器，简化了工艺制作流程，降低了成本，且由于不需要额外插入天线层，从而使得屏幕的透光性不受影响，从而提升了屏幕的显示效果。
本申请的实施例，在显示面板的至少部分感应电极的一端连接频分器，可以使得触控功能的感应电极既可以作为触控的传感器，也可以作为天线的辐射体，显示面板的触控功能和电子设备的天线辐射互相不受影响，且可以同时工作，从而提升了用户体验。
可选地，如图3所示，RFIC芯片1和IC芯片2贴装在所述柔性线路板(Flexible Printed Circuit，FPC)4上，其中，频分器3也可以设置在柔性线路板4上，柔性线路板4的连接器41一端与电子设备的主板连接。RFIC芯片1和触控IC芯片2通过柔性线路板4上的走线与频分器3连接，频分器3通过柔性线路板4上的走线连接至第一感应电极组的一端。其中，柔性线路板4上的走线通过异方性导电胶膜(Anisotropic Conductive Film，ACF)邦定(bonding)工艺连接到第一感应电极组的一端。需要说明的是，RFIC芯片1和IC芯片2还可以贴装在电子设备的主板或者其他电路板上。
可选地，多个感应电极组中除第一感应电极组外的第二感应电极组直接与触控集成电路芯片2连接，即第二感应电极组不复用为天线。
该实施例中，除第一感应电极组外的其他感应电极(即所述第二感应电极组)不复用为天线，即仅实现其触控功能，无需连接频分器3，可以直接与触控IC芯片2连接。如图2所示，第4-11组为第二感应电极组。需要说明的是，第一感应电极组的数量可以根据天线辐射性能需求选择。
如图1和图2所示，每个感应电极组包括多个电极块，多个电极块依次连接形成为沿行排列的感应电极组，或者形成为沿列排列的感应电极组。图1和图2所示的电极块的形状为菱形，也可以根据需求设置为其它形状。如图2所示的第1-8组感应电极组，每一组感应电极组中的电极块沿行排列，也就是沿X方向排列并依次连接，第9-14组感应电极组，每一组感应电极组沿列排列，也就是沿Y方向排列并依次连接。
其中，第一感应电极组可以包括：沿行方向排列的感应电极租，和/或，沿列方向排列的感应电极组。
需要复用为天线的第一感应电极组，可以在所有的感应电极组中选择沿行方向排列的感应电极组，也可以选择沿列方向排列的感应电极组，还可以在行方向和列方向分别选择，均可以实现感应电极的天线功能。可选地，可以在行方向选择至少一组感应电极组复用为天线，并在列方向选择至少一组感应电极组复用为天线，这样，由于X向和Y向都有若干感应电极，当作为天线使用时，可形成阵列，提升天线的增益，从而提升手势操作的距离。
可选地，多个感应电极组分布于相互绝缘的两层；其中，分布于第一层中的感应电极组沿行方向排布，分布于第二层中的感应电极组沿列方向排布。
该实施例中，在显示面板的基板上，将多个感应电极组铺设为两层并且进行图案化，一层负责行方向(即X方向)，另一层负责列方向(即Y方向)，铺设的两层感应电极组之间绝缘，通过X方向和Y方向电极电容的变化来定位，实现触控功能，并且，对于连接有频分器3的感应电极组，还可以同时实现天线辐射功能。
可选地，多个感应电极组分布于同一层；其中，沿行方向排布的感应电极组与沿列方向排布的感应电极组之间相互绝缘。
该实施例中，多个感应电极组可以在基板上铺设为同一层，感应电极组中的电极块可以为氧化铟锡(Indium Tin Oxide，ITO)材料，或者为其它透明 的导电金属材料，X向和Y向的电极块分别由细的金属线串连在一起，X向与Y向十字重叠的部分可以增设一层绝缘薄片，使得X向与Y向的感应电极组之间彼此绝缘，没有电气连接。由于X向和Y向都铺设有感应电极，可以识别3D的手势，使得各种复杂的手势操作都可以识别，提升手势操作的用户体验。
在部分串在一起的X向的感应电极组的一端引入一个频分器3，频分器3的另一端分别连接触控IC和RFIC，在部分串在一起的Y向的感应电极组的一端引入一个频分器3，频分器3的另一端分别连接触控IC和RFIC，实现该部分感应电极组的天线复用。
感应电极组中的电极块为透明的导电金属材料形成的感应电极，这些感应电极铺设在透明的介质基材上，介质基材的厚度为几个微米到几百微米之间，感应电极的厚度为几十纳米到几微米之间。该实施例中的感应电极为透明的金属材料，使得其构成的显示面板为透明，不会影响屏幕的显示效果，进而保证用户的触控体验和视觉体验。
可选地，频分器3的第一连接端与触控集成电路芯片2电连接；频分器3的第二连接端与射频集成电路RFIC芯片1电连接；第一连接端的工作频率低于所述第二连接端的工作频率。
第一连接端为频分器3的低频端，即频分器3的低频端与触控IC芯片2电连接；第二连接端为频分器3的高频端，如手势雷达收发芯片，即频分器3的高频端与RFIC芯片1电连接。第一感应电极组可以同时工作在触控感应状态和天线辐射状态。这样，在保证第一感应电极组的触控功能的同时，还可以实现第一感应电极组的天线辐射功能。由于频分器3的引入，第一感应电极组既可以作为触控的传感器，也可以作为手势雷达的天线辐射体，且可以同时工作，不需要在原来的触控层上再插入一层天线层，有效避免了天线和触控之间的相互干扰。
可选地，频分器3也可以设计为单刀双掷开关，即第一感应电极组与单刀双掷开关的一端点连接，单刀双掷开关的两个触点分别连接RFIC芯片1和触控IC芯片2，在检测到用户触控屏幕的动作时，控制单刀双掷开关切换至与所述触控IC芯片2连接，实第一感应电极组的触控功能，在检测到电子设 备需要发射或者接收信号时，将单刀双掷开关切换至与RFIC芯片1连接，使第一感应电极组实现天线的发射和接收功能。
可选地，如图4所示，多个感应电极组设置在所述显示面板的触控层5；显示面板还包括：液晶层玻璃盖板6和偏光片7，触控层5位于液晶层玻璃盖板6和偏光片7之间。触控层5与偏光片7之间通过热塑性聚酯(Polyethylene terephthalate，PET)材料连接。在触控层5的透明基层材料上，铺设多个感应电极组，且感应电极组中的电极块为透明金属材料，因此不会影响所述显示面板的透光性。多个感应电极组中的部分感应电极组复用为天线，通过频分器3与RFIC芯片1和触控IC芯片2分别连接，能够使感应电极组实现触控功能的同时，也能实现天线的发射和接收功能。
显示面板还包括位于液晶层玻璃盖板6下层的液晶层8、位于液晶层8下层的液晶层下玻璃9、位于液晶层下玻璃9下层的第二偏光片10、位于底层的背光源11，以及设置在偏光片7上层的保护玻璃12，偏光片7和保护玻璃12之间通过粘合剂连接。
可选地，本申请实施例可以用于无线城际网络Wireless Metropolitan Area Network，WMAN)、无线广域网络(Wireless Wide Area Network，WWAN)、无线区域网络(Wireless Local Area Networks，WLAN)、无线个人网络(Wireless Personal Area Network，WPAN)、多输入多输出(Multiple-Input Multiple-Output，MIMO)、射频识别(Radio Frequency Identification，RFID)，甚至是近场通信(Near Field Communication，NFC)、无线充电(Wireless Power Consortium，WPC)以及FM等无线通信设计与应用上，还可以用于电磁兼容比吸收率(Specific Absorption Rate，SAR)与助听器兼容性(Hearing Aid Compatibility，HAC)等对人体安全、健康，与佩戴的电子器件(如助听器或心率调整器等)相容性的法规测试与实际设计及应用上。
本申请提供电子设备可以为手机，本领域技术人员可以理解，除了手机作为电子设备之外，亦可适用于其它具备显示屏的电子设备，如平板电脑、电子书阅读器、MP3(动态影像专家压缩标准音频层面3，Moving Picture Experts Group Audio Layer III)播放器、MP4(动态影像专家压缩标准音频层面4，Moving Picture Experts Group Audio Layer IV)播放器、膝上型便携计算机、 车载电脑、台式计算机、机顶盒、智能电视机、可穿戴设备等等均在本申请实施例的保护范围之内。
本申请的实施例，在部分感应电极组的一端引入一个频分器，可以使得显示面板的触控层的感应电极组既可以作为触控的传感器，也可以作为天线的辐射体，触控体验和天线辐射互相不受影响，且可以同时工作，从而提升了用户体验；不需要额外在触控屏幕上插入一层天线层，仅需要在屏幕的FPC电路上增加一个频分器，简化了工艺制作流程，降低了成本，且由于不需要额外插入天线层，使得屏幕的透光性不受影响，从而提升了屏幕的显示效果；多个感应电极组呈行列交叉排布，当感应电极组作为天线使用时，可形成阵列，提升天线的增益，从而提升手势操作的距离；由于行方向和列方向均排布有感应电极，可以识别3D的手势，使得各种复杂的手势操作都可以识别，提升手势操作的用户体验。
本说明书中的各个实施例均采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似的部分互相参见即可。
尽管已描述了本申请实施例的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例做出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本申请实施例范围的所有变更和修改。
最后，还需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，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、物品或者终端设备不仅包括那些要素，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、物品或者终端设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者终端设备中还存在另外的相同要素。
以上所述的是本申请的优选实施方式，应当指出对于本技术领域的普通 人员来说，在不脱离本申请所述的原理前提下还可以作出若干改进和润饰，这些改进和润饰也在本申请的保护范围内。
