Description

一种阵列基板及显示装置

技术领域
本发明涉及显示装置技术领域，尤其涉及一种阵列基板及显示装置。
背景技术
液晶显示装置通常由彩膜基板、阵列基板以及填充在彩膜基板和阵列基板之间的液晶和封框胶组成。封框胶涂覆在彩膜基板或阵列基板上，并靠近彩膜基板和阵列基板的四周边缘分布，通过封框胶固化将彩膜基板和阵列基板结合在一起形成液晶盒，能够保持彩膜基板和阵列基板之间的盒厚，实现液晶盒的密封用以切断液晶分子与外界的接触。
封框胶固化通常需要通过紫外光固化和热固化两道工艺，如果封框胶固化异常，则未完全固化的封框胶就会对液晶造成污染。在现有技术中，为了降低封框胶对液晶的污染，要求封框胶内金属线的设计有较高的开口率，却很少考虑封框胶涂布位置与金属线设置位置对液晶污染的影响。然而，随着显示装置分辨率的提高，封框胶开口率会越来越小，如果仅通过提高封框胶开口率来提高封框胶固化率用以降低液晶污染，势必越来越困难。
因此，有必要优化封框胶近液晶侧金属线设计，提高近液晶侧封框胶固化率，用以降低未完全固化的封框胶对液晶的污染。

附图说明

图9为本发明实施例二提供的显示装置的局部剖视图。
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，下面将结合附图对本发明作进一步地详细描述。
如图1和图2所示，为本发明实施例一中，提供的一种阵列基板，包括本体1，该本体1上形成有位于本体1四周边缘并用于封框胶涂布的封胶涂布区2以及位于本体1中部并由封胶涂布区2包围而成的液晶填充区3；其中，
在封胶涂布区2中，设有位于本体1上的金属走线结构4，且金属走线结构4均包括多个间隔设置的金属线；其中，封胶涂布区2包括对应于多个金属线之间的间隙的透光区；
在封胶涂布区2靠近液晶填充区3一侧的区域内，靠近液晶填充区3的 透光区L2的占比大于远离液晶填充区3的透光区L2的占比；其中，透光区L2的占比为透光区L2的面积与对应的封胶涂布区2的面积比值。
应当说明的是，透光区L2的占比越大，则越说明UV光透过率越高，因此在封胶涂布区2靠近液晶填充区3一侧的区域内，靠近液晶填充区3的透光区的占比大于远离液晶填充区3的透光区的占比，则表示相对于传统的金属走线结构4的布线规律，金属线在封胶涂布区2形成的透光区L2面积逐渐在增大，使得透光区L2增大的面积，特别是在靠近液晶填充区3一侧的封胶涂布区2内，体现的更明显。
在本发明实施例一中，在封胶涂布区2总设计宽度有限的情况下，通过增大封框胶近液晶侧金属线间距或减小近液晶侧金属线宽度来提高透光区L2的占比，从而提高近液晶侧UV光透过率来提高近液晶侧封框胶固化率，用以降低未完全固化的封框胶对液晶的污染。
在一个实施例中，金属走线结构4中所含多个金属线的宽度会以线性递减规律或非线性递减规律在由金属走线结构4朝向液晶填充区3方向上进行递减，且金属走线结构4中每两相邻的金属线的间距均相等。
在另一个实施例中，金属走线结构4中所含多个金属线的宽度均相等，且金属走线结构4中每两相邻的金属线的间距会以线性递增规律或非线性递增规律在由金属走线结构4朝向液晶填充区3方向上进行递增。
在又一个实施例中，金属走线结构4中所含多个金属线的宽度会以线性 递减规律或非线性递减规律在由金属走线结构4朝向液晶填充区3方向上进行递减，且金属走线结构4中每两相邻的金属线的间距会以线性递增规律或非线性递增规律在由金属走线结构4朝向液晶填充区3方向进行递增。
可以理解的是，金属走线结构4中所含多个金属线的宽度也可以由某一个位于中间的金属线起往朝向液晶填充区3方向以线性递减规律或非线性递减规律进行递减，或者金属走线结构4中每两相邻的金属线的间距也可以由某一个位于中间的金属线起往朝向液晶填充区3方向以线性递增规律或非线性递增规律进行递增，只要满足透光区L2的占比沿朝向液晶填充区3方向逐渐增大即可。
可以理解的是，上述多个金属线的形状包括但不限于矩形、椭圆形等。
在本发明实施例一中，上述金属走线结构4中所含多个金属线可以是都由单层结构的金属线组成，也可以是由单层结构和叠层结构的金属线混合组成，还可以是都由叠层结构的金属线组成。为了叙述方便，下面以矩形状的金属线进行举例说明。应当说明的是，在图2至图8中，液晶填充区3位于金属走线结构4的右侧。
(1)单层结构金属线组成：
如图3所示，为本发明实施例一提供的阵列基板中金属走线结构4的一平面结构示意图，多个金属线中每两相邻之间的间距会以线性递增规律(直线)由中间某一金属线起往朝向液晶填充区3进行递增，此时金属线的宽度 不变，通过间距改变，使得近液晶填充区3的间距比中间的间距大，如d3＞d2＞d1＞d，提高近液晶侧UV光透过率。
如图4所示，为本发明实施例一提供的阵列基板中金属走线结构4的另一平面结构示意图，多个金属线中每两相邻之间的间距会以非线性递增规律(折线)由中间某一金属线往朝向液晶填充区3进行递增，此时金属线的宽度不变，通过间距改变，使得近液晶填充区3的间距比中间的间距大，如d2＞d1＞d，也能提高近液晶侧UV光透过率。
如图5所示，为本发明实施例一提供的阵列基板中金属走线结构4的又一平面结构示意图，多个金属线的宽度会以线性递减规律(直线)由中间某一金属线往朝向液晶填充区3进行递减，此时金属线的间距不变，通过宽度改变，使得近液晶填充区3的宽度比中间的宽度小，如d3＞d2＞d1＞d，并改变面积，也能提高近液晶侧UV光透过率。
如图6所示，为本发明实施例一提供的阵列基板中金属走线结构4的又一平面结构示意图，多个金属线的宽度会以非线性递增规律(折线)由中间某一金属线往朝向液晶填充区3进行递减，此时金属线的间距不变，通过宽度改变，使得近液晶填充区3的宽度比中间的宽度小，如d3＞d2＞d1＞d，并改变面积，也能提高近液晶侧UV光透过率。
应当说明的是，金属走线结构4中所含多个金属线还可以通过间距和宽度同时进行改变来实现提高近液晶侧UV光透过率，间距递增改变可以参考 图3和图4的方式，宽度递减改变可以参考图5和图6的方式。
(2)单层结构和叠层结构的金属线混合组成：
这种混合结构可以参照上述情况(1)单层结构的多种方式来提高近液晶侧UV光透过率，即也是通过间距或宽度改变来提高近液晶侧UV光透过率。
如图7所示，为本发明实施例一提供的阵列基板中金属走线结构4的又一平面结构示意图，是对图5的一种变形，多个金属线的宽度会以线性递减规律(直线)由中间某一金属线往朝向液晶填充区3进行递减，此时金属线的间距不变，通过宽度改变，使得近液晶填充区3的宽度比中间的宽度小，如d3＞d2＞d1＞d，提高近液晶侧UV光透过率。
(3)叠层结构的金属线组成：
这种叠层结构可以参照上述情况(1)单层结构的多种方式来提高近液晶侧UV光透过率，即也是通过间距或宽度改变来提高近液晶侧UV光透过率。
如图8所示，为本发明实施例一提供的阵列基板中金属走线结构4的又一平面结构示意图，是对图3的一种变形，将图3中的单层结构都转换成图8中相同的叠层结构，提高近液晶侧UV光透过率。
在本发明实施例一中，阵列基板为TFT基板，因此阵列基板的本体1包括由下往上依序设置的第一衬底基板11、第一金属层12、栅极绝缘层13、 有源层14、第二金属层15、钝化层16和像素电极层17。当然，为了制程方便，可以将框胶材料设置在阵列基板上，因此还包括：涂布于本体1的封胶涂布区2上并覆盖于每一金属走线结构4上的封框胶5。
如图9所示，相应于本发明实施例一提供的阵列基板，本发明实施例二还提供了一种显示装置，包括本发明实施例一提供的阵列基板1以及彩膜基板5。由于本发明实施例二中的阵列基板与本发明实施例一中的阵列基板具有相同的结构及连接关系，具体请参考本发明实施例一中的阵列基板的相关内容，因此在此不再一一赘述。
在本发明实施例二中，阵列基板1通过其上设置的封框胶5与彩膜基板6粘合在一起，使得其上的液晶填充区3与彩膜基板6密封形成用于填充液晶分子的液晶盒。
在本发明实施例二中，彩膜基板6包括第二衬底基板61、位于第二衬底基板61上的黑色矩阵62、彩色滤光层63、保护层64和金属电极层65。其中，彩色滤光层61包括红色色阻层631、绿色色阻层632和蓝色色阻层633。
综上所述，实施本发明实施例，具有如下有益效果：本发明在封框胶总设计宽度有限的情况下，通过增大封框胶近液晶侧金属线间距(即金属线的间距均会以线性递增规律或非线性递增规律在由金属走线结构朝向液晶填充区方向进行递增)或减小近液晶侧金属线宽度(即金属线的宽度均会以线性递减规律或非线性递减规律在由金属走线结构朝向液晶填充区方向进行 递减)来提高近液晶侧UV光透过率，提高近液晶侧封框胶固化率，用以降低未完全固化的封框胶对液晶的污染。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
