Description

一种液晶显示屏以及长条形液晶显示屏的制备方法 技术领域
本发明涉及液晶显示技术领域,尤其涉及一种液晶显示屏以及长条形液晶显示屏的制备方法。
背景技术
液晶显示器(Liquid Crystal Display，LCD)，为平面超薄的显示设备，它由一定数量的彩色或黑白像素组成，放置于光源或者反射面前方。液晶显示器功耗很低，并且具有高画质、体积小、重量轻的特点，因此倍受大家青睐，成为显示器的主流。
液晶显示屏是液晶显示器的重要组成部分，参阅图1，液晶显示屏主要包括液晶面板1、用于向液晶面板1提供数据信号的源极驱动模块2以及用于向液晶面板1提供数据信号的栅极驱动模块3。通常地，源极驱动模块2设置于液晶面板1的上方侧面，如图1所示，源极驱动模块2包括印刷电路板(Printed Circuit Board，PCB)21以及多个覆晶薄膜(Chip On Film，COF)22，覆晶薄膜22连接印刷电路板21和液晶面板1，将印刷电路板21产生的数据信号传输至液晶面板1，一般采用热压技术将覆晶薄膜22的两端分别与液晶面板1的玻璃基板电极和印刷电路板21的电极相连接。如图1所示，栅极驱动模块3则通常设置在液晶面板1的左方侧面，栅极驱动模块3包括多个栅极驱动芯片31，栅极驱动芯片31可以是通过COG(Chip On Glass)工艺直接连接在液晶面板1的玻璃基板上。
在商用的液晶显示中，有一种长条形液晶显示屏被广泛应用在数码指示上，例如的士广告、行政服务大厅窗口指示、航站楼或高铁站路标指示、大型商场指示等。长条形液晶显示屏长宽比通常为16:3、16:4等，这种非常规的液晶显示屏的取得方法，通常是利用现有的长宽比为16:9的液晶显示屏通过切除保留1/3，1/4或1/2等获得。参阅图1和图2，将如图1所示的液晶显示屏切割(沿X线切割)为长条形液晶显示屏时，必须保留具有源极驱动模块2的这一侧，若液晶面板1中在靠近源极驱动模块2的这一侧具有不良显示点，则该液晶显示屏不可用作加 工长条形液晶显示屏。并且，一张原始的液晶显示屏只能切割获得一张长条形液晶显示屏，切除掉比较大的面积，造成浪费。
发明内容
鉴于现有技术存在的不足，本发明提供了一种液晶显示屏，该液晶显示屏主要应用于制备长条形液晶显示屏，通过对液晶显示屏结构的改进，提高了液晶显示屏的利用率。
为了实现上述目的，本发明采用了如下的技术方案：
一种液晶显示屏，其中，所述液晶显示屏包括液晶面板，所述液晶面板包括显示区域和位于显示区域周边的线路连接区域；其中，位于所述显示区域上方侧面和下方侧面的线路连接区域分别连接有一源极驱动模块，两个源极驱动模块可独立地向所述液晶面板提供数据信号；位于所述显示区域左方侧面的线路连接区域连接有一栅极驱动模块，用于向所述液晶面板提供扫描信号。

本发明还提供了一种长条形液晶显示屏的制备方法，其中，将如上所述的液晶显示屏沿横向切割，获得长条形液晶显示屏。
相比于现有技术，本发明实施例中提供的液晶显示屏，通过在上方侧面和下方侧面分别设置有独立的源极驱动模块，该液晶显示屏应用于制备长条形液晶显示屏时，当液晶显示屏的液晶面板中上方侧的区域或下方侧的区域包含不良显示点时，该液晶显示屏还是可以切割出一张长条形液晶显示屏，当不良显 示点位于液晶面板的中间区域时，该液晶显示屏可以切割出两张长条形液晶显示屏，提高了液晶显示屏的利用率。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面结合附图对本发明的具体实施方式进行详细说明。这些优选实施方式的示例在附图中进行了例示。附图中所示和根据附图描述的本发明的实施方式仅仅是示例性的，并且本发明并不限于这些实施方式。
在此，还需要说明的是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与根据本发明的方案密切相关的结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
本实施例提供了一种液晶显示屏，如图3所示，所述液晶显示屏包括液晶面板1，所述液晶面板1包括显示区域11和位于显示区域11周边的线路连接区域12a、12b、12c。其中，位于所述显示区域11上方侧面和下方侧面的线路连接区域12a、12b分别连接有一源极驱动模块2，两个源极驱动模块2可独立地向所述液晶面板1提供数据信号。位于所述显示区域11左方侧面的线路连接区域12c连接有一栅极驱动模块3，用于向所述液晶面板1提供扫描信号。
具体地，所述源极驱动模块2包括印刷电路板21以及多个覆晶薄膜22，所述覆晶薄膜22上设置有源极驱动芯片23，所述覆晶薄膜22驱动IC(源极驱动芯片 23)固定于柔性线路板上形成的，即Chip On Film，COF。所述覆晶薄膜22的两端分别电性连接所述印刷电路板21和所述液晶面板1的线路连接区域12a、12b，一般采用热压技术将覆晶薄膜22的两端分别与液晶面板1的线路连接区域12a、12b的电极和印刷电路板21的电极相连接。
具体地，所述栅极驱动模块3包括多个栅极驱动芯片31，所述栅极驱动芯片31通过COG(Chip On Glass)工艺直接连接在液晶面板1的线路连接区域12c上。
如上结构的的液晶显示屏，其长宽比通常为16:9，主要是用于制备长条形液晶显示屏。所述长条形液晶显示屏的长宽要比小于所述液晶显示屏的长宽比，长条形液晶显示屏的长宽比为16:3或16:4。通过将长宽比为16:9的液晶显示屏切割，获得长宽比为16:3或16:4长条形液晶显示屏。
本实施例中的液晶显示屏所使用的液晶面板1，通常是在液晶面板的加工工艺中发现有不良显示点存在，这些不良显示点随机存在与液晶面板1的显示区域11中。
将如上提供的液晶显示屏，沿横向切割获得长条形液晶显示屏。以液晶显示屏的长宽比为16:9，所要制备的长条形液晶显示屏的长宽比为16:3作为具体的例子，主要存在以下几种情形：
(1)、如图4所示，液晶面板1的显示区域11中不存在不良显示点，或者是当不良显示点(NG)位于显示区域11的中间区域11a时，沿横向(如图4中沿X1线和X2线)切割获得两张长条形液晶显示屏。位于上方侧面的源极驱动模块2和液晶面板1的显示区域11中的区域11b形成一张长条形液晶显示屏；位于下方侧面的源极驱动模块2和液晶面板1的显示区域11中的区域11c形成另一张长条形液晶显示屏。
(2)、如图5所示，当不良显示点(NG)位于显示区域11的靠近上方的区域11b时(或者区域11a也同时存在不良点)，沿横向(如图5中沿X2线)切割获得一张长条形液晶显示屏。位于下方侧面的源极驱动模块2和液晶面板1的显示区域11中的区域11c形成一张长条形液晶显示屏。
(3)、如图6所示，当不良显示点(NG)位于显示区域11的靠近下方的区域11c时(或者区域11a也同时存在不良点)，沿横向(如图6中沿X1线)切割获得一张长条形液晶显示屏。位于上方侧面的源极驱动模块2和液晶面板1的显示区域11中的区域11b形成一张长条形液晶显示屏。
此外，如果显示区域11的上、中、下三个区域11a、11b和11c都存在不良显示点，则该液晶显示屏被报废。一般地，假如液晶面板中的显示区域11的上、中、下三个区域11a、11b和11c都存在不良显示点，则在液晶面板的加工工艺中处理这些不良，不会再进一步加工形成如本实施例中提供的液晶显示屏。
综上所述，本发明实施例中提供的液晶显示屏，通过在上方侧面和下方侧面分别设置有独立的源极驱动模块，该液晶显示屏应用于制备长条形液晶显示屏时，当液晶显示屏的液晶面板中上方侧的区域或下方侧的区域包含不良显示点时，该液晶显示屏还是可以切割出一张长条形液晶显示屏，当不良显示点位于液晶面板的中间区域时，该液晶显示屏可以切割出两张长条形液晶显示屏，提高了液晶显示屏的利用率。
