Description

具有NFC通信功能的显示装置
本专利申请要求在2016年03月10日同一日提交的中国专利申请号为201610136085.5以及中国专利申请号为201610136365.6的优先权，这些专利申请的全文以引用的方式并入本申请中。
技术领域
本发明涉及显示技术领域，特别是涉及一种具有NFC通信功能的显示装置。
背景技术
显示技术的种类较多，包括液晶显示(Liquid Crystal Display,LCD)和有机发光二极管显示(organic light-emitting diode,OLED)等。其中非常有吸引力的是OLED显示，其具有自发光显示、轻薄省电等优点，还可基于柔性材料而制成柔性显示器，可以被卷曲、折叠或者作为可穿戴设备的一部分。OLED的发光原理是在两个电极之间沉积非常薄的有机发光材料，对有机发光材料通以电流，通过载流子注入和复合而导致发光。
石墨烯是已知的世上最薄、最坚硬的纳米材料，它几乎是完全透明的，只吸收2.3％的光，而且石墨烯的电阻率极低，仅10-8Ω·m，是一种具有极好前景的透明导体，适合用来制作透明触控屏幕、光板、甚至是太阳能电池。此外，相关研究表明石墨烯的层状纳米结构具有吸收电磁的特性，是一种新型的吸波材料。
纳米银线(silver nanowire)技术，是将纳米银线墨水材料涂抹在塑胶或者玻璃基板上，然后利用镭射光刻技术，刻画制成具有纳米级别银线导电网络图案的透明的导电薄膜。纳米银线除具有银优良的导电性之外，由于纳米级别的尺寸效应，还具有优异的透光性、耐曲挠性，因此被视为是最有可能替代传统ITO透明电极的材料。再次，纳米银线薄膜具有较小的弯曲半径，且在弯曲时电阻变化率较小，应用在具有曲面显示的设备，例如智能手表、手 环等上的时候，更具有优势。
NFC(Near Field Communication)即近距离无线通讯技术，该技术允许电子设备之间进行非接触式点对点数据传输(在十厘米内)。这个技术由免接触式射频识别(RFID)演变而来，并向下兼容RFID，主要用于手机等手持设备中提供M2M(Machine to Machine)的通信。由于近场通讯具有天然的安全性，因此，NFC技术被认为在手机支付等领域具有很大的应用前景。
目前，除了常用的手机，越来越多的电子设备特别是穿戴类产品都开始附带NFC功能。但是，由于穿戴类产品及其它小尺寸电子设备的外形限制，对电子器件的尺寸及集成化要求比较高。目前，集成到产品内部的NFC天线通常采用的方式为在PCB板或FPC软板上，以金属走线做成线圈，然后将此含有线圈的PCB板或FPC软板贴在电池或外壳上。其缺点是：
(1)、NFC天线在设备内部占据极大的空间，无法适应小型电子设备的设计需求。
(2)、常规NFC天线是在PCB板或FPC软板上通过金属引线做成线圈结构，然后将此含有线圈的PCB板或FPC软板贴在电池或外壳上。电池、外壳的反复拆装，会导致NFC天线磨损或者对位不准，进而影响NFC信号传输。
(3)、由于NFC通信距离较近，为了保证NFC信号的强度及稳定性，一些电子设备诸如腕表等提出将NFC天线放到显示面的需求。
现有将NFC天线集成到显示屏正面的方案，NFC天线走线采用银、铜等导体，NFC天线的线圈放到显示区外并且中间区域镂空，避免NFC天线走线遮挡显示区。但是，这样的方案为了保证NFC天线走线空间，NFC线框就要做的非常大，进而增大了整个模组在显示区以外的边框尺寸。该方案一定程度上解决了常规NFC天线走线易磨损、易错位的问题，但是过大的模组边框尺寸同样不利于小型电子设备的设计。
发明内容
为克服上述现有技术中的缺陷，本发明所要解决的技术问题为提供一种 附带NFC功能显示装置，通过将NFC天线走线集成在显示装置内，且采用透明导电材料制成，NFC信号灵敏度和可靠性高，NFC天线走线不易破损、不易偏位，NFC天线走线可以放到显示区，可实现模组的窄边框设计。

[第五实施例]
图10为本发明第五实施例中显示装置的结构示意图，请参图10，该显示装置包括显示面板10、隔离层100、透明薄膜40和盖板玻璃110。在本实施例中，显示面板10、隔离层100、透明薄膜40和盖板玻璃110依次层叠设置，即隔离层100设置在显示面板10上，透明薄膜40设置在隔离层100上，盖板玻璃110覆盖设置在透明薄膜40上，各个结构层之间可以通过透明光学胶(OCA)贴合。透明薄膜40位于显示面板10的显示面一侧。

如上述第二实施例所示，NFC天线走线70由在该透明薄膜40的双面镀有ITO或石墨烯或纳米银线等透明低阻抗材料构成，在该透明薄膜40的第一表面41(本实施例中为透明薄膜40的下表面)上形成第一天线走线71，在该透明薄膜40相对的第二表面42(本实施例中为透明薄膜40的上表面)上形成第二天线走线72，该第一表面41上的第一天线走线71和该第二表面42上的第二天线走线72电性连接在一起，从而形成NFC天线走线70。关于第一天线走线71和第二天线走线72的详细结构可以参见上述第二实施例，在此不再赘述。
[第六实施例]
图11为本发明第六实施例中显示装置的结构示意图，请参图11，该显示装置包括显示面板10、隔离层100、透明薄膜40和盖板玻璃110。在本实施例中，显示面板10、隔离层100、透明薄膜40和盖板玻璃110依次层叠设置，即隔离层100设置在显示面板10上，透明薄膜40设置在隔离层100上，盖板玻璃110覆盖设置在透明薄膜40上，各个结构层之间可以通过透明光学胶(OCA)贴合。透明薄膜40位于显示面板10的显示面一侧。
该显示装置内集成设置有NFC天线走线80，NFC天线走线80位于显示面板10的显示面一侧，NFC天线走线80由透明导体材料例如ITO或石墨烯或纳米银线等制成。在本实施例中，NFC天线走线80形成在透明薄膜40的一个表面上，使得NFC天线走线80位于靠近显示面板10的显示面一侧。
如上述第三实施例所示，NFC天线走线80由在该透明薄膜40的单面镀有ITO或石墨烯或纳米银线等透明低阻抗材料构成，在该透明薄膜40的第一表面41(即透明薄膜40的下表面)上形成NFC天线走线80。关于NFC天线走线80的详细结构可以参见上述第三实施例，在此不再赘述。
可以理解地，在其他实施例中，NFC天线走线80也可以形成在该透明薄膜40的第二表面42(即透明薄膜40的上表面)上。
[第七实施例]
图12为本发明第七实施例中显示装置的结构示意图，请参图12，该显示装置包括显示面板10、隔离层100、透明薄膜40和盖板玻璃110。在本实施例中，显示面板10、隔离层100、透明薄膜40和盖板玻璃110依次层叠设 置，即隔离层100设置在显示面板10上，透明薄膜40设置在隔离层100上，盖板玻璃110覆盖设置在透明薄膜40上，各个结构层之间可以通过透明光学胶(OCA)贴合。透明薄膜40位于显示面板10的显示面一侧。
该显示装置内集成设置有NFC天线走线60，NFC天线走线60位于显示面板10的显示面一侧，NFC天线走线60由透明导体材料例如ITO或石墨烯或纳米银线等制成。在本实施例中，NFC天线走线60形成在透明薄膜40和盖板玻璃110之间，使得NFC天线走线60位于靠近显示面板10的显示面一侧。
在本实施例中，NFC天线走线60包括第一天线走线61和第二天线走线62，第一天线走线61形成在透明薄膜40的一个表面42(本实施例中为透明薄膜40的上表面)上，第二天线走线62形成在盖板玻璃110的一个表面111(本实施例中为盖板玻璃110的下表面)上。该透明薄膜40和该盖板玻璃110具有天线走线的两个表面42、111相对贴合在一起，从而形成NFC天线走线60。关于第一天线走线61和第二天线走线62的详细结构可以参见上述第一实施例，在此不再赘述。
也就是说，上述第七实施例(图12)与第四实施例(图9)的区别在于，在上述第四实施例中盖板玻璃110仅作为保护盖板，NFC天线走线60是形成在另外两个透明薄膜40、50上；而在上述第七实施例中盖板玻璃110除了作为保护盖板之外，还在盖板玻璃110的一个表面111上形成部分的NFC天线走线(即第二天线走线62)，因此第七实施例相比于第四实施例而言可以减少一个透明薄膜，有利于降低成本和产品厚度。
在上述第四实施例至第七实施例中，该显示装置内未设置触摸感应层30，因此该显示装置适合于不需要触摸功能的场合使用。
在上述第四实施例至第七实施例中，隔离层100设置在显示面板10与NFC天线走线60、70、80之间，隔离层100为镀有石墨烯等透明吸波材料的薄膜，可隔离显示面板10的屏体信号对NFC信号产生干扰及信号削弱。隔离层100上如镀有石墨烯，石墨烯的吸波性可以更好的保证NFC信号强度，不会对NFC信号造成干扰。
在上述第四实施例至第七实施例中，盖板玻璃110覆盖在NFC天线走线 60、70、80的远离显示面板10的一侧，起保护作用。而且在上述第七实施例中，盖板玻璃110还同时起到设置部分的NFC天线走线的作用。
[第八实施例至第十一实施例]
图13为本发明第八实施例中显示装置的结构示意图，图14为本发明第九实施例中显示装置的结构示意图，图15为本发明第十实施例中显示装置的结构示意图，图16为本发明第十一实施例中显示装置的结构示意图，请参图13至图16，第八实施例至第十一实施例中的显示装置与上述第四实施例至第七实施例中的显示装置分别对应且结构基本相同，其区别仅在于第八实施例至第十一实施例中的显示装置还包括屏蔽层20和触摸感应层30，其中屏蔽层20设置在显示面板10上，触摸感应层30设置在屏蔽层20上，隔离层100设置在触摸感应层30上。
在上述第八实施例至第十一实施例中，触摸感应层30设置在显示面板10与NFC天线走线60、70、80之间，触摸感应层30使该显示装置具有触摸功能，触摸感应层30的图形可采用ITO或石墨烯或纳米银线作为导体制成。
屏蔽层20设置在显示面板10与触摸感应层30之间，屏蔽层20为镀有ITO或石墨烯或纳米银线等材料的薄膜，可屏蔽显示面板10内的屏体信号对上方的触摸感应层30产生干扰，屏蔽层20可以根据实际情况保留或者去掉。
隔离层100设置在触摸感应层30与NFC天线走线60、70、80之间，隔离层100为优选镀有石墨烯等透明吸波材料的薄膜，主要作用是隔离触摸感应层30的感应信号对NFC信号产生干扰及信号削弱。由于触摸感应层30与NFC天线走线60、70、80之间设置镀有石墨烯的隔离层100，因此触摸感应层30的图形可以由ITO等金属氧化物制成，NFC天线走线60、70、80的磁场容易受到金属的干扰，但隔离层100可保证NFC天线磁场免受触摸感应层30中金属导体的干扰。
隔离层100可以根据实际情况保留或者去掉，当去掉隔离层100时，触摸感应层30的图形优选采用石墨烯作为导体制成，因为石墨烯的吸波性可以更好的保证NFC信号强度，不会对NFC信号造成干扰。
[第十二实施例]
图17为本发明第十二实施例中显示装置的结构示意图，请参图17，该显示装置包括OLED显示面板10，该OLED显示面板10包括依次层叠设置的OLED屏体封装盖11、OLED第一电极12、OLED发光区13、OLED第二电极14、OLED基板15以及绝缘保护膜16。具体地，OLED第一电极12设置在OLED屏体封装盖11上，OLED发光区13设置在OLED第一电极12上，OLED第二电极14设置在OLED发光区13上，OLED基板15设置在OLED第二电极14上，绝缘保护膜16设置在OLED基板15上。OLED基板15具有朝向OLED发光区13一侧的第一表面151和远离OLED发光区13一侧的第二表面152。
在该OLED显示面板10中，OLED屏体封装盖11起到封装的作用，一般为封装盖与干燥剂或者封装膜与干燥剂组成，以避免水氧进入OLED发光区13；OLED第一电极12一般为铝、银、镁等不透光金属电极，并且为整面设置；OLED发光区13包含电子注入层、电子传输层、发光层、空穴注入层、空穴传输层等结构层；OLED第二电极14一般为ITO等透明导电材料形成；OLED基板15一般为玻璃、柔性薄膜等透明材质，OLED第二电极14通过刻蚀或印刷等方式制作形成在OLED基板15的第一表面151一侧，OLED第二电极14具体包括OLED像素电极及引线，其中引线连接至OLED驱动芯片(图未示)。OLED发光区13朝向OLED基板15所在一侧发光进行显示(如图中箭头A所示)，即该OLED显示面板10的画面通过OLED基板15所在的一侧进行显示。
该OLED显示面板10内集成设置有NFC天线走线90，NFC天线走线90形成在OLED基板15的第二表面152上，绝缘保护膜16覆盖NFC天线走线90，NFC天线走线90由透明导体材料例如ITO或石墨烯或纳米银线等制成。由于OLED显示面板10的画面通过OLED基板15所在的一侧进行显示，使得集成设置在OLED显示面板10内的NFC天线走线90位于该OLED显示面板10的显示面一侧。在本实施例中，NFC天线走线90直接制作形成在OLED基板15的第二表面152上，即NFC天线走线90与OLED基板15的第二表面152之间没有中间膜层。NFC天线走线90例如通过刻蚀或印刷的方式直接制作形成在OLED基板15的第二表面152上。
图18为图17中OLED基板的其中一实施方式的平面示意图，请参图18，在本实施例中，NFC天线走线90直接制作形成在OLED基板15的第二表面152上，NFC天线走线90包括第一接合垫901、第二接合垫902以及连接在第一接合垫901与第二接合垫902之间的走线906，NFC天线走线90可以通过刻蚀或印刷等方式直接制作在OLED基板15的第二表面152上。第一接合垫901和第二接合垫902用于与FPC邦定或者其它方式引出后，连接至外部电路。
图19为图17中OLED基板的另一实施方式的平面示意图，请参图19，在本实施例中，NFC天线走线90直接制作形成在OLED基板15的第二表面152上，NFC天线走线90包括第一接合垫901、第二接合垫902、第三接合垫903、连接在第一接合垫901与第二接合垫902之间的走线906以及透明绝缘导线908，其中第一接合垫901和第三接合垫903位于OLED基板15的外侧边缘处，OLED基板15内侧的第二接合垫902通过透明绝缘导线908连接至外侧的第三接合垫903，使得第二接合垫902与第三接合垫903电性相连，但是透明绝缘导线908与走线906相互绝缘。第一接合垫901和第三接合垫903相互错开用于与FPC邦定或者其它方式引出后，连接至外部电路。NFC天线走线90可以通过刻蚀或印刷等方式直接制作在OLED基板15的第二表面152上。
由于NFC天线走线90选用ITO或石墨烯或纳米银线等透明导体材料制成，NFC天线走线90可以根据需求任意排布，不局限于非显示区，此时NFC天线走线90可以位于该OLED显示面板10的显示区内，不会影响显示，且利于该OLED显示面板10的窄边框设计。
在OLED基板15的第二表面152上直接制作形成NFC天线走线90后，再在NFC天线走线90上覆盖绝缘保护膜16，由绝缘保护膜16覆盖NFC天线走线90，对NFC天线走线90起到保护和绝缘作用。绝缘保护膜16可以为玻璃、亚克力、柔性薄膜等材质；另外，绝缘保护膜16也可以由圆偏光片或透明光学胶(OCA)等部件或材质替代。
[第十三实施例]
图20为本发明第十三实施例中显示装置的结构示意图，请参图20，本 实施例与上述第十二实施例不同之处在于，为了防止NFC信号受到OLED屏体的干扰，在NFC天线走线90与OLED基板15的第二表面152之间还制作有一层透明的吸波材料层120，即在OLED基板15的第二表面152上先制作一层透明的吸波材料层120，然后在该透明的吸波材料层120上再制作形成一层NFC天线走线90。该透明的吸波材料层120例如为石墨烯制成，主要作用是隔离下方的屏体信号对上方NFC信号产生干扰及信号削弱，而石墨烯的吸波性可以更好的保证NFC信号强度，不会对NFC信号造成干扰。关于该NFC天线走线90的结构可以参见图18或图19，在此不再赘述。
[第十四实施例]
图21为本发明第十四实施例中显示装置的制作流程图，用于制作图17或图20所示的OLED显示面板10，具体地，该OLED显示面板10的制作方法包括如下步骤：
提供OLED基板15，OLED基板15具有相对的第一表面151和第二表面152，OLED基板15一般为玻璃、柔性薄膜等透明材质；
在OLED基板15的第二表面152上制作形成NFC天线走线90，NFC天线走线90可通过刻蚀或印刷的方式制作形成在OLED基板15的第二表面152上，NFC天线走线90由ITO或石墨烯或纳米银线等透明导体材料制成；
在OLED基板15的第一表面151一侧制作形成OLED第二电极14，OLED第二电极14具体包括OLED像素电极及引线；
在OLED第二电极14上形成OLED发光区13，OLED发光区13包含电子注入层、电子传输层、发光层、空穴注入层、空穴传输层等结构层；
在OLED发光区13上形成OLED第一电极12，OLED第一电极12一般为铝、银、镁等不透光金属电极，并且整面地覆盖在OLED发光区13上；
在OLED第一电极12上封装OLED屏体封装盖11，OLED屏体封装盖11起到封装的作用，一般为封装盖与干燥剂或者封装膜与干燥剂组成，以避免水氧进入OLED发光区13；
在NFC天线走线90上覆盖绝缘保护膜16，其中OLED发光区13朝向OLED基板15所在一侧发光进行显示使NFC天线走线90位于该OLED显示 面板10的显示面一侧，绝缘保护膜16对NFC天线走线90起到保护和绝缘作用。
进一步地，该制作方法还包括在该NFC天线走线90与该OLED基板15的第二表面152之间制作形成一层透明的吸波材料层120，该透明的吸波材料层120先制作在该OLED基板15的第二表面152上，该NFC天线走线90再制作形成在该透明的吸波材料层120上。该透明的吸波材料层120例如为石墨烯制成，主要作用是隔离下方的屏体信号对上方NFC信号产生干扰及信号削弱，而石墨烯的吸波性可以更好的保证NFC信号强度，不会对NFC信号造成干扰。
综上所述，上述各实施例提出了将NFC天线走线与显示面板集成的显示装置，NFC天线走线集成设置在显示装置内，可减少元件数量和减小模组厚度，精简制程和降低生产成本，且通过将NFC天线走线设置在小型电子设备表面(显示面)，对于需要从设备表面进行NFC通信的产品来说，缩短了NFC信号通信距离，使得NFC信号的灵敏度和可靠性更高，也同时解决常规的电池、外壳的拆装对NFC天线带来的易破损、易偏位的问题。
现有NFC天线走线采用银、铜等导体，NFC天线的线圈与显示面板集成时，线圈必须放到显示区外，以避免NFC天线走线遮挡显示区，同时为了保证NFC天线走线空间，NFC线框就要做的非常大，无疑增大了模组非显示区的边框尺寸。本发明实施例中通过采用ITO或石墨烯或纳米银线等透明低阻抗材料作为NFC天线导体，使得NFC天线走线可以放到显示区，不用担心NFC天线走线进入显示区影响显示效果，NFC天线走线的外形结构及与显示面板的贴合位置可以自由选择，可实现模组的窄边框设计，满足手机、手表或其他便携式电子设备的窄边框设计需求，在小尺寸电子设备应用领域例如穿戴类产品，具备较好市场前景。
现有NFC天线走线与触摸屏集成时，中间需要加一层铁氧体作为吸波材料，以保证NFC天线磁场免受周围金属导体的干扰。本发明实施例中通过设置触摸感应层，使显示装置具有触摸功能，触摸感应层的图形优选采用性能稳定的石墨烯材料作为导体，石墨烯的吸波性能决定了触摸感应层同时可以充当NFC天线吸波材料的角色，而无需再增加铁氧体层。
本发明实施例中在显示面板与触摸感应层之间设置屏蔽层，屏蔽层可以屏蔽显示面板内的屏体信号对上方的触摸感应层产生干扰；在触摸感应层与NFC天线走线之间设置隔离层，隔离层可以确保触摸感应层不会对NFC信号造成干扰；而设置在最外侧的盖板玻璃可以对NFC天线走线起保护作用。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
