Description

一种用于防止ACF胶溢出到显示区的引线结构及方法 技术领域
本发明涉及液晶面板制造领域，尤其涉及ACF(Anisotropic Conductive Film，单向导电胶)胶贴附的方法。
背景技术
随着电子技术的发展，人们的日常生活和工作中越来越离不开电子产品，液晶显示屏作为电子产品的重要部件，也紧密影响着人们的使用体验，所以，不断改善液晶显示屏的制造方法和制备工艺显得尤为重要。
在液晶面板的制造过程中，液晶显示屏连接FPC(Flexible Printed Circuit，柔性电路板)时，将液晶显示屏上的连接引线与FPC上的连接引线通过标记进行精确定位，然后热压贴合。但是，为了保证FPC与液晶显示屏之间的电信号导通性，在热压贴合之前常常在FPC上贴附ACF胶带。由于ACF胶本身含有导电粒子，能够保证FPC与液晶显示屏之间的良好导电性。
但是，传统FPC上的引线设计方法，由于引线排列过于紧密，在热压的时候ACF胶受力后没有缓冲空间，容易使ACF胶溢出到液晶显示屏上的显示区，影响到液晶面板的显示成像。另外，为了防止溢胶现象，采用增加缓冲空间的设计方法，将会加大引线之间的距离，导致引线不能为ACF胶提供足够的支撑力，ACF胶直接与液晶面板贴附，产生溢胶。ACF胶溢出到显示区不仅影响到液晶显示成像，而且在热压过程中也容易使引线断裂，给企业带来不必要的损失，所 以，防止或避免溢胶现象的发生至关重要。
发明内容
本发明所要解决的技术问题是提供一种用于防止ACF胶溢出到显示区的引线结构及方法，从而解决溢胶现象影响液晶显示成像的问题。

进一步地，每十条所述横向引线之间设置有与一条所述纵向引线，横向引线与纵向引线之间形成缓冲区域。
进一步地，每一条所述横向引线均包括电极、基板引线和弯折部，所述弯折部连接所述电极与基板引线，使所述横向引线呈台阶状。
进一步地，所述基板引线贴于显示面板，所述电极与显示面板之间形成用于容置光阻剂的容置空间。
进一步地，所述基板引线与电路板之间形成溢出区域。
进一步地，所述纵向引线与横向引线交替排列使引线布局呈连续的n字形状、H字形状中的一种。
一种用于防止ACF胶溢出到显示区的方法，包括以下步骤：
(1)将所述纵向引线与横向引线排列于所述显示面板与电路板之间；
(2)在所述横向引线与显示面板之间的容置空间中放置光阻剂；
(3)在所述横向引线、纵向引线与电路板之间放置ACF胶。
进一步地，所述显示面板上设有显示区，显示面板为液晶显示面板或触摸传感面板。
进一步地，所述电路板为柔性基板。

本发明的有益效果：本发明提供的一种用于防止ACF胶溢出到显示区的引线结构及方法，方法简单，操作方便，在液晶面板与FPC热压贴合时，通过增加ACF胶的容纳空间和阻挡ACF胶溢出到显示区的工艺方法，有效地解决了ACF胶溢出到显示区的问题，保证了液晶显示面板的成像质量，挽救了企业在生产制造过程中因溢胶影响显示成像产生的损失。
附图说明
图1是本发明实施例防止ACF胶溢出到显示区的示意图。
具体实施方式
为了更好地阐述本发明的技术特点和结构，以下结合本发明的优选实施例及其附图进行详细描述。
参阅图1，本发明提供的一种用于防止ACF胶溢出到显示区的引线结构及方法，包括显示面板100和电路板400，该显示面板100与电路板400之间设置有引线200，其中，引线200包括若干条纵向引线210和若干条横向引线220，每五条横向引线220设置有一条纵向引线210。本实施例在考虑引线200排列的密集度、提供可靠支撑力的因素，取每十条横向引线220之间设置有与一条纵 向引线210，横向引线220与纵向引线210之间形成缓冲区域310，实现有足够的缓冲区域310容纳挤压后的ACF胶300，同时，阻挡已经溢出ACF胶300进入显示区110，从而达到防止ACF胶300溢出到显示区110的目的。该方法包括以下步骤：
(1)设置引线200。显示面板100上设有显示区110，在显示面板100与电路板400之间排列有若干条引线200，该引线200包括若干条纵向引线210和若干条横向引线220，其中，每十条横向引线220之间设置有一条纵向引线210，并且横向引线220与纵向引线210之间形成缓冲区域310，当显示面板100与电路板400之间热压贴合时，该缓冲区域310用于容纳被挤压的ACF胶300，由于改变传统引线的纵向排列方式，采用纵向引线210与横向引线220相互交替的排列，有效地增大了缓冲区域310，使缓冲区域310具有足够的空间容纳被挤压后的ACF胶300，有效保证了显示面板100与电路板400之间的支撑力。
(2)在横向引线220与显示面板100之间容置有光阻剂120，每一条横向引线220均包括电极221、基板引线223和弯折部222，其中，弯折部222连接电极221与基板引线223，位于电极221与基板引线223之间，使所述横向引线220呈台阶状，基板引线223贴于显示面板100，电极221高于基板引线223，与显示面板100之间形成用于容置光阻剂120的容置空间130，基板引线223与电路板400之间形成溢出区域320。
(3)横向引线220、纵向引线210与电路板400之间设置ACF胶300。当显示面板100与电路板400之间热压贴合时，被挤压的ACF胶300容纳于缓冲区域310中，当缓冲区域310不能容纳多余的ACF胶300时，这些少部分的ACF胶300溢出到溢出区域320，由于横向引线220呈台阶状，电极221与基板引线 223之间存在高度差，使弯折部222产生阻挡作用，防止溢出的ACF胶300进入显示区110。当溢出区域320不能容纳ACF胶300时，多余的ACF胶300将从外侧溢出，可外设擦拭装置清理附着于显示面板100和电路板400侧壁上的ACF胶300。
在此工艺方法中，光阻剂120为OC光阻，电极221为铟锡氧化物，显示面板100为液晶显示面板或触摸传感面板，电路板400为柔性基板。
综上所述，本发明提供的一种用于防止ACF胶溢出到显示区的引线结构及方法，方法简单，操作方便，在液晶面板与FPC热压贴合时，通过增加ACF胶的容纳空间和阻挡ACF胶溢出到显示区的工艺方法，有效地解决了ACF胶溢出到显示区的问题，保证了液晶显示面板的成像质量，挽救了企业在生产制造过程中因溢胶影响显示成像产生的损失。
