Description

液晶显示模组
本发明要求2015年12月1日递交的发明名称为“液晶显示模组”的申请号201510872266.X的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本申请涉及液晶显示技术领域，尤其涉及一种液晶显示模组。
背景技术
液晶显示面板设计及制造过程中，在设计面板信号走线时，除了满足其产品功能(正常显示)必备的一些基本的信号线(如栅极信号线、数据信号线)之外，设计者还会保留一些检测产品性能是否完备的一些其他信号线，通常这些信号线在液晶显示面板绑定(Bonding)柔性电路板(Flexible Printed Circuit，FPC)或驱动芯片(Driver IC)之前，我们会将其接到液晶盒测试焊盘(Cell test pad)上用于方便测试人员用示波器检测其电信号状况来分析液晶Cell里面的电路的工作状态，在后期生产时，我们会将这些信号电路通过电路连接，灌入一个特定的电平，使液晶面板Cell内部一些非必要电路(用于设计检测、模组生产时不用)短路(Short)或挂起(Open)。
为实现非必要电路的短路或挂起，业内人士通常会将需要测试的电路在阵列基板上走线连到液晶盒测试焊盘上，用于测试人员检测。而测试焊盘的另一边，会设计走线连至驱动芯片或柔性电路板的绑定引脚上，在绑定驱动芯片或柔性电路板时，会在柔性电路板上设计一个电路走线，用以连接到我们需要的电压准位的焊盘和连接液晶盒测试焊盘的焊盘，使这个电压准位经过液晶盒测试焊盘再传回到液晶面板液晶盒内，使一些非必要电路短路或挂起。上述方案意在将原有的驱动芯片或柔性电路板的绑定引焊盘上的电位以柔性电路板上的电路走线为桥接引回薄膜晶体管阵列基板，这样虽然可以实现其必要功能，但缺点是焊盘繁多、无法减少驱动芯片或者柔性电路板绑定时焊盘的数量，无法缩小柔性电路板的面积或者减小驱动芯片的尺寸，并且必须借助柔性电路板才能绑定驱动电路，使这一制程没有获得更多效益。
发明内容
本发明所要解决的技术问题在于提供一种绑定区占用空间小的液晶显示模组。
为了实现上述目的，本发明实施方式采用如下技术方案：
提供一种液晶显示模组，包括液晶显示面板和驱动集成电路，所述液晶显示面板包括测试焊盘、第一焊盘和第二焊盘，所述第一焊盘包括间隔设置的第一子焊盘和第二子焊盘，所述第二子焊盘电连接所述测试焊盘，所述驱动集成电路包括至少两个第三焊盘，所述第三焊盘与所述第一焊盘和所述第二焊盘一一对应地进行绑定，所述第一子焊盘和所述第二子焊盘共同绑定至其中一个所述第三焊盘上，以实现所述第一子焊盘和所述第二子焊盘之间的短路。
优选的，所述液晶显示面板包括多个液晶盒，所述测试焊盘通过第一测试信号线电连接至所述液晶盒，所述第一子焊盘和所述第二焊盘均通过显示信号线电连接至所述液晶盒。
优选的，所述第二子焊盘通过第二测试信号线电连接所述测试焊盘。
优选的，所述第一子焊盘的焊接面积和所述第二子焊盘的焊接面积之和小于所述第二焊盘的焊接面积。
优选的，所述第一焊盘和所述第二焊盘在第一方向上排列，所述第一子焊盘和所述第二子焊盘在所述第一方向上的长度小于等于所述第二焊盘在所述第一方向上的长度。
优选的，所述第一子焊盘和所述第二子焊盘在所述第一方向上并排设置。
优选的，在垂直于所述第一方向的第二方向上，所述第一子焊盘的长度为D1，所述第二子焊盘的长度为D2，所述第一子焊盘和所述第二子焊盘的间距为d，所述第二焊盘的长度为D，所述D1、所述D2、所述d和所述D满足：D1+d+D2≤D。
优选的，所述D1和所述D2满足：D1＝D2。
优选的，所述D和所述d满足：1/4D≤d≤1/2D。
优选的，所述第一焊盘与所述第三焊盘之间以及所述第二焊盘与所述第三焊盘之间设置有异方性导电胶膜。
相较于现有技术，本发明具有以下有益效果：
本实施例所述液晶显示模组巧妙地利用所述驱动集成电路上的所述第三焊盘实现所述液晶显示面板上的所述第一子焊盘和所述第二子焊盘的短路，促使所述第一子焊盘和所述第二子焊盘具有相同的电压准位。现有技术则是借助绑定的柔性电路板上的一个短路线连接所述第一电压准位的焊盘和所述测试焊盘，该种方案需要在绑定区额外多布置一条电路线和一对绑定焊盘，增加了绑定区的占用空间。因此，本实施例所述液晶显示模组相对于现有技术来说，需绑定的焊盘数量更少，绑定区所需要的占用空间也更小，因此可以减小所述驱动集成电路的体积，例如绑定至所述液晶显示面板的柔性电路板或者驱动芯片的体积，有利于所述液晶显示模组的体积小型化的发展。
附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明实施例提供的一种液晶显示模组绑定前的结构示意图。
图2是图1中A处结构的放大示意图。
图3是本发明实施例提供的一种液晶显示模组绑定后的部分结构示意图。
具体实施方式
下面将结合本发明实施方式中的附图，对本发明实施方式中的技术方案进行清楚、完整地描述。
请一并参阅图1至图3，本发明实施例提供一种液晶显示模组，包括液晶显示面板1和驱动集成电路2。所述液晶显示面板1包括显示区1a和设置在所述显示区1a周边的非显示区1b。所述非显示区1b内设置有第一绑定区1c和测试焊盘13。所述测试焊盘13通过第一测试信号线131连接至所述显示区1a内的液晶盒(图中未示出)，测试人员可以将示波器电连接到所述测试焊盘13上，从而通过检测所述液晶盒的电信号状况来分析所述液晶显示面板内部的电路的工作 状态。所述第一绑定区1c包括间隔排列的一个第一焊盘11和多个第二焊盘12，所述第一焊盘11包括间隔设置的第一子焊盘111和第二子焊盘112，所述第一子焊盘111和多个所述第二焊盘12通过显示信号线14电连接至所述液晶盒，所述第二子焊盘112通过第二测试信号线132电连接至所述测试焊盘13。在本实施例中，由于所述第一子焊盘111和所述第二子焊盘112间隔设置，也即两者相互独立，因此当所述第一子焊盘111通过所述显示信号线14电连接至所述液晶盒，所述第二子焊盘112电连接所述测试焊盘13后、通过所述第一测试信号线131电连接至所述液晶盒时，所述显示信号线14和所述第一测试信号线131并不会相互干扰，测试人员在所述液晶显示面板1绑定所述驱动集成电路2之前能够顺利地完成对所述液晶显示面板1内部电路情况的测试。在本实施例中，所述第一子焊盘111可以通过第二测试信号线132电连接至所述测试焊盘13，也可以通过其他连接方式实现与所述测试焊盘13的电连接。
请一并参阅图1至图3，本实施例所述驱动集成电路2包括第二绑定区21，所述第二绑定区21包括间隔设置的多个第三焊盘21，所述第三焊盘21和所述第一焊盘11、所述第二焊盘12一一对应地进行绑定。所述第一子焊盘111和所述第二子焊盘112共同绑定至其中一个所述第三焊盘12上，以实现所述第一子焊盘111和所述第二子焊盘112之间的短路，因此，所述第一子焊盘111与所述第二子焊盘112会因为被所述第三焊盘21短路而具有相同的电压准位。在本实施例中，所述液晶显示模组将所述第一焊盘11设计在与具有第一电压准位的所述第三焊盘21对应的绑定位置处，多个所述第二焊盘12设置在与其他所述第三焊盘21对应的绑定位置处。当所述驱动集成电路2绑定到所述液晶显示面板1后，所述第一子焊盘111和所述第二子焊盘112均具有第一电压准位，所述第一子焊盘111通过所述显示信号线14传送第一电压准位至所述液晶盒以参与所述显示区1a的显示，所述第二子焊盘112传送第一电压准位至所述测试焊盘13、再通过所述第二测试信号线132传送至所述液晶盒，使所述液晶显示面板内的测试电路被短路或挂起，从而不影响所述显示区1a的正常显示。
可以理解的，本实施例所述液晶显示模组巧妙地利用所述驱动集成电路2上的所述第三焊盘21实现所述液晶显示面板1上的所述第一子焊盘111和所述第二子焊盘112的短路，促使所述第一子焊盘111和所述第二子焊盘112具有相同的电压准位。现有技术则是借助绑定的柔性电路板上的一个短路线连接所述 第一电压准位的焊盘和所述测试焊盘，该种方案需要在绑定区额外多布置一条电路线和一对绑定焊盘，增加了绑定区的占用空间。因此，本实施例所述液晶显示模组相对于现有技术来说，需绑定的焊盘数量更少，绑定区所需要的占用空间也更小，因此可以减小所述驱动集成电路2的体积，例如绑定至所述液晶显示面板1的柔性电路板或者驱动芯片的体积，有利于所述液晶显示模组的体积小型化的发展。
应当理解的是，“所述第一焊盘”并不限定其必须是一个单一的焊盘，此处是为了说明所述第一子焊盘111和所述第二子焊盘112组合后与所述第二焊盘相类似(例如占用差不多的绑定空间、均用于与一个所述第三焊盘绑定)，并且与所述第二焊盘相区分开。“所述非显示区1b”包括但不限定于在存在所述显示区1a的一侧周边。“所述第一电压准位”并不限定于某一个电压准位，只要是能够实现使所述液晶显示面板内的测试电路被短路或挂起的电压准位均在本发明所保护范围内。
进一步的，请一并参阅图1和图2，所述第一子焊盘111和所述第二子焊盘112的焊接面积之和小于所述第二焊盘的焊接面积。
进一步的，定义所述第一焊盘11和多个所述第二焊盘12的排列方向为第一方向，所述第二焊盘12在第二方向上延伸。所述第一子焊盘111和所述第二子焊盘112在所述第一方向上的长度小于等于所述第二焊盘12在所述第一方向上的长度，优选所述第一子焊盘111和所述第二子焊盘112在所述第一方向上的长度等于所述第二焊盘12在所述第一方向上的长度。所述第一子焊盘111和所述第二子焊盘112在所述第二方向上居中对齐。本实施例所述第一焊盘11可以顺利地与所述第三焊盘13进行绑定。
