Description

一种集成 NFC天线的有机电致发光显示器
本申请要求于 2012 年 04 月 06 日提交中国专利局、 申请号为 201220145136.8、 名称为 "一种显示屏 "和于 2012年 7月 5 日提交中国专利局、 申请号为 201210232600.1、 发明名称为 "一种集成 NFC天线的有机电致发光 显示器"的中国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及近场通信技术领域， 尤其涉及一种集成 NFC天线的有机电致 发光显示器。
背景技术
NFC ( Near Field Communication , 近场通信 )技术是今后电子产品的一种 必备技术， 市场庞大。 现有 NFC产品的天线主要是做在电池的某一面， 或者 贴在外壳的里面， 采用的方式一般为在 PCB ( Printed Circuit Board, 印刷电路 板)或 FPC ( Flexible Printed Circuit, 软性线路板 )上， 以金属走线做成线圏， 然后将此含有线圏的 PCB板或 FPC贴在电池或者外壳上。 其缺点主要有： 电 池与外壳经常反复拆装， 这样就使得 NFC天线的接线处容易磨损或者出现对 位不准的问题， 最终造成天线信号变差， 影响 NFC产品功能的使用。 另外， NFC产品的天线， 一般位于电子产品的外壳里面， 如果选择金属材料做外壳， 会影响 NFC信号的传播， 限制了电子产品外壳在选材时， 选择坚固的金属材 料。
例如， ^艮多装配有 NFC 天线和有机电致发光显示器 （OLED, Organic
Light-Emitting Diode )的电子产品就存在上述问题。所谓有机电致发光显示器， 是一种新兴的平板显示器， 具有主动发光、 对比度高、 响应速度快、 轻薄等诸 多优点， 被誉为可以取代液晶显示器（LCD )的新一代显示器。 OLED的发光 原理是在阳极和阴极之间***各种功能层， 包括电荷注入层、 电荷传输层以及 发光层等， 通过在电极之间施加适当的电压， 器件就能发光。
鉴于装配有 NFC天线和有机电致发光显示器的电子产品的 NFC天线设置 方式不尽合理， 其接线处容易磨损或者对位不准， 由此造成天线信号质量变差 的问题。 并且限制了电子产品的外壳选择范围， 而生产有机电致发光显示器过 程中， 具备集成 NFC天线的能力， 有必要设计一种新的集成了 NFC天线的有 机电致发光显示器， 以解决上述问题。
发明内容
有鉴于此， 本发明目的在于提供一种集成 NFC天线的有机电致发光显示 器，可防止天线接线处磨损或者对位不准，有利于保证天线信号的质量。另外， 装配了上述的有机电致发光显示器的电子产品，从显示器的正面传递信号， 在 选择外壳选材时， 不受 NFC天线的限制。
为解决以上技术问题， 本发明提供的技术方案是： 一种集成 NFC天线的 有机电致发光显示器，该 NFC天线设置于该有机电致发光显示器的显示屏上， 其中的 NFC接口搭载该显示屏的输出线路，并连接到该显示屏的控制主板上。
较优地， 该显示屏依次包括保护部件、 第一电极、 有机发光功能层、 第二 电极及透明基板， 该 NFC天线通过导电材料引出到该显示屏的输出走线上。
较优地， 该 NFC天线设置于该透明基板的内侧表面上。
较优地， 该 NFC天线设置于该透明基板的外侧表面上， 且覆盖绝缘保护 膜。
较优地， 该 NFC天线设置于该保护部件的外侧表面上， 且覆盖绝缘保护 膜。
较优地， 该 NFC天线设置于该保护部件的内侧表面上。
较优地， 该 NFC天线设置于该第一电极外表面， 且用绝缘保护膜与第一 电极绝缘保护。
较优地， 该 NFC天线通过导电材料连接至该输出走线上。
较优地， 该 NFC天线为以导电材料走线方式制成的多匝线圏。
较优地， 该多匝线圏呈矩形绕制、或圓形绕制或其它与产品外轮廓线相匹 配环形绕制。
较优地， 在该多匝线圏偏显示器内部的一面覆盖一层透明的铁氧体材料。 与现有技术相比，本发明集成 NFC天线的有机电致发光显示器将 NFC天 线直接做在有机电致发光显示器上， 由于 NFC接口搭载显示屏的输出线路， 其连接到控制主板上， 安装后是固定不动的， 不经常拆装， 避免了现有技术中 NFC 天线由于接口磨损及对位不准引起的信号质量变差、 接收失灵等问题。 另外，为方便从显示器显示面接收 NFC信号，或必须从显示器显示面接收 NFC 信号时提供解决方案。 此外， 装配了上述的有机电致发光显示器的电子产品， 从显示器的正面传递信号， 在选择外壳选材时， 不受 NFC天线的限制。
