Description

液晶显示器 技术领域
本发明涉及一种液晶显示器。
背景技术
在IPS与FFS的产品中使用银浆工艺的目的是将薄膜晶体管(TFT)基板上的接地(GND)电位传送到彩色滤光片基板(CF)基板的ITO面电极上。
中国专利CN201320318762.7公开了一种防静电电阻触摸屏。如图1A和图1B所示，该专利公开的防静电电阻触摸屏包括上线ITO菲林1和下线ITO玻璃2，上线ITO菲林1的四周设有两根上银浆线11，下线ITO玻璃2四周设有一根防静电银浆线21和两根下银浆线22。防静电银浆线21设于下线ITO玻璃2的最外围，上线ITO菲林1通过一双面胶层与下线ITO玻璃2粘合。上线ITO菲林1和下线ITO玻璃2之间设有一柔性线路板(FPC)3。FPC 3的导电端分别与上银浆线11、下银浆线22和防静电银浆线21连接。
该中国专利采用柔性线路板3的导电端分别与上银浆线11、下银浆线22和防静电银浆线21连接，以释放该触摸屏的静电。然而，由于涂布银浆的位置在密封区域的外侧，使得TFT基板上的GND线需要通过接触孔引出，再涂上银浆后利用银浆的导电能力把GND电位传到CF基板。现有技术中的关键在于银浆涂布量的安定性、位置的安定性以及ESD对策。如果银浆的涂布量过多，则会导致盒厚不均；相反，如果银浆的涂布量过少、涂布位置偏离等，则会导致导通不良。另外，点胶的过程本身就是制造玻璃制程之一，点胶的良率影响到整个玻璃制程的良率。综上，在目前追求低成本、高良率的前提下，点胶导通并不是将CF与TFT连通的最好的方法。

除非另外限定，否则在本说明书中使用的术语(包括技术术语和科学术语)具有与本领域普通技术人员所通常理解的含义相同的含义。在通用词典中定义的术语应当被解释为具有与相关技术背景下的含义相同的含义，并且除非在本说明书中进行了限定，否则不应以理想化的或过于形式化的意思来解释它们。
如这里所使用的，术语“和/或”包括一个或更多个相关所列项的任意和全部组合。
图2是示出现有技术的液晶显示器的局部示意性剖视图。参照图2，现有技术的液晶显示器100包括液晶面板和背光模组。液晶面板包括阵列基板105和彩色滤光片基板106。背光模组具有容纳液晶面板的空间。背光模组包括：反射片101；框架102和导光板103，设置在反射片101上；发光二极管104，设置在框架102和导光板103之间。另外，阵列基板105设置在发光二极管104上。彩色滤光片基板106设置在阵列基板105上，并与导光板103叠置。在阵列基板105上还设置有点胶，用来将彩色滤光片基板106和薄膜晶体管105电连接。
现有技术的点胶的目的是把阵列基板105上的相关信号传送到彩色滤光片基板106上，其中主要利用银浆的导电能力将所述相关信号传送到彩色滤光片基板上。然而，出于对银浆涂布量的安定性、位置的安定性以及ESD对策的考虑，如果出现涂布量过多的情况，则会导致盒厚不均；如果出现涂布量过少的情况、则会出现涂布位置偏离，从而导致导通不良。此外，点胶的过程本身就是制造玻璃制程之一，点胶的良率影响到整个玻璃制程的良率。
相比之下，本发明的示例性实施例的背光模组通过使用玻璃配合背光组件来对彩色滤光片基板与TFT阵列基板之间进行导通，从而省略了点胶的动作，在不使用银浆的情况下即可使得电信号可靠转移到彩色滤光片基板上。因此，通过对背光模组的结构的细微调整，使得可以实现与现有技术同样的电位导通的作用。
下面，将结合附图来更详细地描述根据本发明的示例性实施例的液晶显示器。
实施例一：
图3是示出根据本发明的实施例一的液晶显示器的示意性剖视图。
参照图3，根据本发明的示例性实施例的液晶显示器200包括液晶面板和背光模组。背光模组具有用于容置液晶面板的容置空间。液晶面板包括阵列基板205和彩色滤光片基板206。背光模组包括：反射片201；导光板203，设置在反射片201上；发光二极管204，设置在导光板203的一侧；阵列基板205，设置在发光二极管204上；彩色滤光片基板206，与阵列基板205相对贴合设置，并与光学膜片(图中未示出)、导光板203等结构叠置。此外，背光模组还包括用于将所述阵列基板205和彩色滤光片基板206电连接的连接构件，连接构件包括压紧结构202E和导电单元207，压紧结构202E用于将导电单元207与阵列基板205压紧贴合，使导电单元207分别与阵列基板205和彩色滤光片基板206电连接。
根据本发明的示例性实施例，压紧结构可以由能够实现上述功能的任一材料制成，例如，塑料、金属等。
根据本发明的示例性实施例，压紧结构202可以延伸。当压紧结构202延伸时，压紧结构可以包括以下结构：压紧结构的一端202A可以弯折并夹设在背光模组内，压紧结构的另一端202B可以延伸至或经过彩色滤光片基板206与阵列基板的交界处的上方。在这种情况下，导电单元207被固定在压紧结构的一端，从而可以使导电单元207分别与阵列基板205和彩色滤光片基板206电连接。
当压紧结构202延伸时，背光模组还可以包括胶框202P，用于与压紧结构202围合形成容置空间。在这种情况下，压紧结构202例如可以与胶框202P一体地成型。压紧结构202可以将导电单元压紧至彩色滤光片基板206与阵列基板205的交界处，从而可以使导电单元207分别与阵列基板205和彩色滤光片基板206电连接。因此，由于未进行点胶工艺，使得能够避免使用银浆来使电位转移到彩色滤光片基板面板上。从而通过对背光模组的结构的细微调整，即可实现将电位导通的目的。
当压紧结构202与胶框202P一体成型时，可以通过注塑工艺使压紧结构202E与胶框202一体式注塑成型。在这种情况下，压紧结构202可以从胶框202P的端部延伸至彩色滤光片基板206与阵列基板205的交界处的上方，并使导电单元可以固定在压紧结构的端部。
根据本发明的示例性实施例，导电单元207可以为导电胶，其可以通过粘贴而固定在压紧结构上，并与阵列基板205压紧贴合，但本发明不限于此。
虽然以上描述了本发明的一种实施例，然而，本发明构思不限于上述实施例，也可以通过下面的实施例来实施。
实施例二：
图4是示出根据本发明的实施例二的液晶显示器300的示意性剖视图。
参照图4，除了通过设置背板以固定导电单元以外，根据本发明的示例性实施例的液晶显示器300与图3示出的根据本发明的示例性实施例的液晶显示器200的结构基本相同或相同。因此，下面将主要描述它们之间的不同，并将省略相同结构的重复描述。
根据本发明的液晶显示器300包括液晶面板和背光模组。背光模组具有用于容置液晶面板的容置空间。液晶面板包括阵列基板305和彩色滤光片基板306。背光模组包括：反射片301；框架302和导光板303，分别设置在反射片301上；发光二极管304，设置在导光板303与框架之间；阵列基板305，设置在发光二极管304上；彩色滤光片基板306，与阵列基板305相对贴合设置，并与光学膜片(图中未示出)、导光板303等结构叠置。此外，背光模组还包括用于将阵列基板305和彩色滤光片基板306电连接的连接构件，连接构件包括压紧结构308和导电单元307，压紧结构308将导电单元307与阵列基板305压紧贴合，使导电单元307分别与阵列基板305和彩色滤光片基板306电连接。
根据本发明的示例性实施例，背光模组还可以包括位于其底部的背板308M。在这种情况下，压紧结构308与背板308M可以一体成型，压紧结构将导电单元307压紧至彩色滤光片基板306与阵列基板305的交界处，使导电单元307分别与阵列基板305和彩色滤光片基板306电连接。
综上，根据本发明的实施例一和实施例二，上述液晶显示器200和300的结构缺点是：由于导电单元的厚度使得连接构件的厚度无法减小，以致如果以液晶显示模组(LCM)作为整体商品时，需要考虑厚度的影响。
基于本发明的上述的示例性实施例存在的缺点，在以液晶显示器作为整体商品的前提下，可以通过参照图5示出的实施例三的液晶显示器的结构来避开厚度差。
实施例三：
图5是示出根据本发明的另一示例性实施例的液晶显示器300-1的示意性剖视图。
参照图5，除了省略了导电单元以外，根据本发明的示例性实施例的液晶显示器400与图4示出的根据本发明的示例性实施例的液晶显示器300的结构基本相同或相同。因此，下面将主要描述它们之间的不同，并将省略相同结构的重复描述。
为了避免图3和图4中所示的根据本发明的示例性实施例的液晶显示器200和300的结构的厚度差的问题，在图5中示出的根据本发明的实施例三的液晶显示器400中，通过将背板设置为具有金属的结构，并省略导电单元，从而可以避免背光模组的厚度差问题。
具体地，参照图5，在根据本发明的实施例三的液晶显示器400中，背板408可以由金属制成，例如，铜、铝等。在这种情况下，可以省略导电单元。具体地，可以将图4中的背板308M、压紧结构308和导电单元307一体成型，并将背板308M和压紧结构308的未与导电单元307接触的内外表面上至少部分地涂覆有绝缘层(未示出)，从而获得图5所示的具有一体的背板408结构。在这种情况下，背板408的端部与彩色滤光片基板406和阵列基板305的交界处接触。由于背板408由金属制成，因此，其未涂覆由绝缘层的端部可以分别与阵列基板405和彩色滤光片基板406电连接。
因此，由于省略了导电单元，使得可以液晶显示器的整体厚度减小。
上面已经描述了三种本发明的示例性实施例，然而，本领域技术人员应该知道的是，以上的示例性实施例只是示例性地示出了本发明的发明构思。也就是说，上述示例性实施例只是向本领域技术人员示出本发明的优选实施例，然而，本发明还可以通过如下的其它实施方式来实施。本发明的保护范围由权利要求限定的范围所限制。
例如，由于根据本发明的示例性实施例的压紧结构可以延伸为或者可以与实施例一的胶框或实施例二背板结合为具有“[”的形状，因此其结合的构造可以具有一定的回复弹性，使得压紧结构可以凭借自身的弹性恢复力将导电单元或者其自身(例如，当压紧结构与背板由金属一体地形成时所构成的结构)的端部紧压，从而可以分别与阵列基板和彩色滤光片基板电连接。然而，为了确 保阵列基板与彩色滤光片基板的电连接，可以在压紧结构的上部增设诸如固定框的固定构件，用来确保导电单元或压紧结构自身的端部与分别与阵列基板和彩色滤光片基板的电连接。
此外，为了确保压紧结构能够压紧导电单元，或者为了确保当压紧结构与背板由金属一体制成时所述一体结构的端部能够压紧导电单元，除了通过压紧结构自身的弹性恢复力，例如还可以在压紧结构的适当位置处(例如靠近导电单元的适当位置处)的上部设置例如外部抵接、卡接、扣接等的限位构件，从而可以通过外部构件的设置来提高压紧结构的向下压力，以确保阵列基板和彩色滤光片之间的电连接。然而，本领域技术人员可以根据实际需要而在不同的位置设计不同的限位件来实现上述功能。
以上描述了本发明的一些示例性实施例，然而，本发明构思不限于上述具体实施例，即，本领域技术人员可以对上述实施例结合本领域的惯用手段而变形和修改上述实施例。
