Abstract

本实用新型涉及一种FPC与LCD玻璃基板的连接结构，包括：LCD玻璃基板、连接在LCD玻璃基板外端上的FPC、及涂覆在LCD玻璃基板与FPC连接处下端的硅胶，所述FPC于其连接端的铜箔上设有金手指，该金手指通过各向异性导电胶热压贴合在LCD玻璃基板外端导线上，FPC下端的聚酰亚胺膜延伸连接到LCD玻璃基板的外端上而贴合在各向异性导电胶的端缘上。本实用新型FPC与LCD玻璃基板的连接结构，通过将聚酰亚胺膜延伸连接至LCD玻璃基板的外端上，提高连接牢固性，增强抗拉强度，避免FPC热压部分的金手指由于连接不牢固而断裂，进而提高产品可靠性及良品率。

Description

FPC与LCD玻璃基板的连接结构
技术领域
本实用新型涉及一种FPC与LCD玻璃基板的连接结构。
背景技术
现有的FPC与LCD玻璃基板的连接结构，如图1所示，包括LCD玻璃基板1与连接在LCD玻璃基板1外端上的FPC3，FPC3是通过其连接端的铜箔32上所设的金手指直接热压贴合在覆有各向异性导电胶10的LCD玻璃基板外端导线上实现导通，经涂覆硅胶13后，完成连接。而上述该种连接结构中，FPC3下端的聚酰亚胺膜34未与各向异性导电胶粘接，容易使FPC热压部分的金手指由于连接不牢固而断裂，从而影响LCD的品质，降低产品的可靠性及良品率。
实用新型内容
本实用新型的目的是提供一种FPC与LCD玻璃基板的连接结构，其连接结构较为牢固，抗拉强度较高，提高产品可靠性及良品率。
为实现上述目的，本实用新型提供一种FPC与LCD玻璃基板的连接结构，包括：LCD玻璃基板、连接在LCD玻璃基板外端上的FPC(柔性线路板)、及涂覆在LCD玻璃基板与FPC连接处下端的硅胶，所述FPC于其连接端的铜箔上设有金手指，该金手指通过各向异性导电胶(ACF)热压贴合在LCD玻璃基板外端导线上，FPC下端的聚酰亚胺膜延伸连接到LCD玻璃基板的外端上而贴合在各向异性导电胶的端缘上。
所述聚酰亚胺膜延伸至LCD玻璃基板的外端上的宽度为0.1-0.2mm。
所述聚酰亚胺膜延伸至LCD玻璃基板的外端上的宽度优选0.2mm。
本实用新型的有益效果是：本实用新型FPC与LCD玻璃基板的连接结构，通过将聚酰亚胺膜延伸连接至LCD玻璃基板的外端上，提高连接牢固性，增强抗拉强度，避免FPC热压部分的金手指由于连接不牢固而断裂，进而提高产品可靠性及良品率。
为了能更进一步了解本实用新型的特征以及技术内容，请参阅以下有关本实用新型的详细说明与附图，然而附图仅提供参考与说明用，并非用来对本实用新型加以限制。
附图说明
下面结合附图，通过对本实用新型的具体实施方式详细描述，将使本实用新型的技术方案及其他有益效果显而易见。
附图中，
图1为现有的FPC与LCD玻璃基板的连接结构示意图；
图2为本实用新型的FPC与LCD玻璃基板的连接结构示意图。
具体实施方式
以下结合附图对本实用新型进行详细描述。
如图2所示，本实用新型FPC与LCD玻璃基板的连接结构包括：LCD玻璃基板2、连接在LCD玻璃基板2外端上的FPC4、及涂覆在LCD玻璃基板2与FPC4连接处下端的硅胶24。
所述FPC4于LCD玻璃基板2外端上连接端的铜箔42上设有金手指(未图示)，该金手指通过各向异性导电胶20热压贴合在LCD玻璃基板2外端导线(未图示)上，从而实现FPC4与LCD的导通。FPC4下端的聚酰亚胺膜44延伸连接到LCD玻璃基板2的外端上而贴合在各向异性导电胶20的端缘上，从而形成一台阶状。所述聚酰亚胺膜44延伸至LCD玻璃基板2的外端上的宽度可为0.1-0.2mm，优选0.2mm，该宽度选择避免了延伸至LCD玻璃基板2上的聚酰亚胺膜44对导通产生不良的影响。
该聚酰亚胺膜44的延伸设置对FPC4铜箔42上的金手指起到一定的保护作用，避免其因弯折等动作而不慎断裂，从而影响其与LCD的导通。
综上所述，本实用新型FPC与LCD玻璃基板的连接结构，通过将聚酰亚胺膜延伸连接至LCD玻璃基板的外端上，提高连接牢固性，增强抗拉强度，避免FPC热压部分的金手指由于连接不牢固而断裂，进而提高产品可靠性及良品率。
以上所述，对于本领域的普通技术人员来说，可以根据本实用新型的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本实用新型后附的权利要求的保护范围。
