Description

显示模组和显示装置
技术领域
本发明属于显示技术领域，具体涉及一种显示模组和显示装置。
背景技术
薄膜晶体管液晶显示器(Thin Film Transistor Liquid CrystalDisplay，TFT-LCD)以其优异的性能而获广泛应用。一般地，TFT-LCD主要包括液晶显示模组和外壳，液晶显示模组包括液晶面板和背光模组等结构。如图1所示，其中，液晶面板包括相对设置的阵列基板1和彩膜基板2以及设于阵列基板1和彩膜基板2之间的液晶层3；背光模组用于为液晶面板提供亮度均一的面光源，其一般包括导光板5、背板6等结构。液晶面板通过胶框7与背光模组的背板6进行连接和固定。
制作薄膜晶体管液晶显示器时，在形成液晶面板的工艺中彩膜基板2上会积累静电荷，而且在显示器的使用过程中，彩膜基板2上也会积累静电荷。彩膜基板2上积累的静电荷，若不能及时导出，会产生静电，而静电往往会击穿COF(柔性电路板)从而造成亮线等显示不良。为了释放彩膜基板2表面上积累的静电荷，现有技术中采取在彩膜基板2的出光面上形成一层透明导电层4(如氧化铟锡层)，通过贴附导电胶带8把透明导电层4与背光模组的背板6(由金属材料制成)进行连接，使静电荷通过导电胶带8传导到背板6上，由接地的背板6传导出去。
发明人发现现有技术中至少存在如下问题：贴附导电胶带时，通常采用人工进行贴附，但由于贴附时操作空间很小，耗时耗工，而且贴附精确度差，产品不良率较高。另外，导电胶带易脱落，特别是在热环境下更容易掉落，造成静电释放不良从而影响显示品质。
发明内容
本发明所要解决的技术问题包括，针对现有的液晶显示器的彩膜基板和背板之间的导电胶带容易脱落而导致静电释放不良进而影响显示品质的问题，提供一种对彩膜基板表面上的静电荷释放良好的显示模组和显示装置。
解决本发明技术问题所采用的技术方案是一种显示模组，其包括显示面板、背光模组以及胶框，所述显示面板包括彩膜基板，彩膜基板的出光面上设有透明导电层；所述背光模组包括背板，所述背板的材料为导电材料；所述胶框设于所述显示面板和背板之间；其中，所述胶框上设有第一开口，所述显示模组还包括具有第一弯折部的导电元件，其第一端穿过第一开口与所述导电层贴合在一起，与第一端相对的第二端与所述背板贴合在一起。
本发明的显示模组的彩膜基板和背板之间连接有导电元件，导电元件可采用金属材料并制作成条状或片状。具有第一弯折部的导电元件穿过第一开口，其两端分别与彩膜基板和背板相贴合，从而使导电元件与彩膜基板以及与背板的连接较为稳固，不容易脱落，因此能够良好地把彩膜基板上的静电荷传导出去，避免了静电荷对显示模组的不良影响，提高了显示模组的显示品质。
优选的是，制作所述导电元件的第一弯折部时形成的弯折角的角度小于90度。
优选的是，所述背板设有第二开口，所述导电元件还具有第二弯折部，所述第二端穿过所述第二开口与所述背板贴合在一起。
进一步优选的是，制作所述导电元件的第二弯折部时形成的弯折角的角度小于90度。
优选的是，所述导电元件的形状为片状。
优选的是，所述导电元件的材料采用不锈钢。
优选的是，所述导电元件的厚度小于0.1mm。
优选的是，所述导电元件靠近所述背板的侧面贴附有导电双面胶。
优选的是，所述导电元件具有铁磁性。
解决本发明技术问题所采用的技术方案是一种显示装置，其包括上述的显示模组。
本发明的显示装置包括上述的显示模组，因此，彩膜基板表面的静电荷能够被良好地传导出去，避免了静电荷对显示模组的不良影响，从而提高了显示装置的显示品质。
附图说明
图1为现有的显示模组的结构示意图；
图2为本发明的实施例1的显示模组的结构示意图；
图3为本发明的实施例1的导电元件的结构示意图。
其中附图标记为：1、阵列基板；2、彩膜基板；3、液晶层；4、透明导电层；5、导光板；6、背板；7、胶框；8、导电胶带；9、导电元件。
具体实施方式
为使本领域技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明作进一步详细描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例1：
本实施例提供一种显示模组，如图2和图3所示，所述显示模组包括显示面板、背光模组以及胶框7，所述显示面板包括彩膜基板2，以及与彩膜基板2相对设置的阵列基板1，彩膜基板2和阵列基板1之间设有液晶层3，彩膜基板2的出光面上设有透明导电层4，透明导电层4的材料可选用氧化铟锡等透明的导电材料；所述背光模组包括背板6以及导光板5，背板6的材料为导电材料，导电材料可采用金属材料；胶框7设于所述显示面板和背板6之间，用于支撑和固定显示面板以及导光板5等。
胶框7上设有第一开口，所述显示模组还包括具有第一弯折部的导电元件9，其第一端穿过第一开口与透明导电层4贴合在一起，与第一端相对的第二端与背板6贴合在一起，背板6进行接地设计。这样，导电元件9可以良好地把彩膜基板2上累积的静电荷传导出去。
为了更好地把彩膜基板2上累积的静电荷传导出去，可通过增加导电元件9与透明导电层4以及与背板6的接触面积的方式来实现，因此，导电元件9的形状可优选为片状。当然，把导电元件9制作成条状也可以实现本发明的目的。
如图3所示，为了使导电元件9与透明导电层4和背板6贴合得更为稳固，优选的，制作导电元件9的第一弯折部时形成的弯折角(在附图3中以β表示)的角度小于90度，也即制作导电元件9时，使其第一弯折部形成的弯折角的角度小于90度，而导电元件9安装到显示模组上后，导电元件9的第一弯折部的弯折角大约为90度，这样，第一弯折部被“打开”之后形成的作用力将导电元件9与透明导电层4以及背板6贴合得更为稳固，固定性好，不易脱落，能很好地将彩膜基板2表面累积的静电荷传导出去。
在本实施例中，优选的，背板6设有第二开口，所述导电元件9还具有第二弯折部，所述第二端穿过所述第二开口与所述背板6贴合在一起。
进一步优选的是，制作所述导电元件9的第二弯折部时形成的弯折角(在附图3中以γ表示)的角度小于90度。第二弯折部的弯折角的角度也设计为小于90度，其目的与上述将第一弯折部的弯折角设计为小于90度的目的相同，在此，不再重复进行描述。
本实施例中，导电元件9的材料可优选采用不锈钢。进一步优选的，导电元件9的厚度小于0.1mm。生产中，可采用0.1mm或者更薄的SUS钢板。
其中，第一开口和第二开口的大小可根据采用的导电元件9的材料以及尺寸，根据具体情况进行确定。生产中，比如，当导电元件9采用SUS钢板时，第一开口和第二开口的长度为10mm以及宽度为0.2mm为宜。
在本实施例中，为了更稳固地将导电元件9与透明导电层4以及背板6固定在一起，优选的，导电元件9靠近所述背板6的侧面贴附有导电双面胶(附图未示出)，即通过使用导电双面胶将导电元件9与背板6粘贴在一起以实现更稳固的固定。或者也可以优选地使导电元件9具有铁磁性，可通过对导电元件9进行镀磁使导电元件9具有铁磁性或在导电元件9与背板6接触的侧面粘贴磁铁，也相当于导电元件9具有铁磁性。这样，由于磁场的作用，导电元件9与背板6之间将会相互吸附在一起，提高了二者的固定效果。
本实施例的显示模组的彩膜基板2和背板6之间连接有导电元件9，导电元件9可采用金属材料并优选制作成片状，且导电元件9具有第一弯折部或者还具有第二弯折部，导电元件9的两端分别与彩膜基板2上的透明导电层4和背板6相贴合，从而使导电元件9与彩膜基板2以及与背板6的连接较为稳固，不容易脱落，因此能够良好地把彩膜基板2上的静电荷传导出去，避免了静电荷对显示模组的不良影响，提高了显示模组的显示品质。
实施例2：
本实施例提供一种显示装置，其包括实施例1中的显示模组，当然还应当包括其他如电源单元以及驱动控制单元等已知的结构，在此不再进行详细描述。
本实施例中的显示装置可以为液晶显示装置，另外，还可以为：电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
本实施例的显示装置包括实施例1中的显示模组，因此，彩膜基板表面的静电荷能够被良好地传导出去，避免了静电荷对显示模组的不良影响，从而提高了显示装置的显示品质。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
