Description

一种液晶显示面板
【技术领域】
本发明涉及液晶显示领域,特别涉及一种液晶显示面板。
【背景技术】
随着液晶显示技术的不断发展,液晶显示面板已大量应用于各种电子设备中。目前,各种电子设备的设计者都致力于将产品的体积缩小,以符合市场及消费者的需求。然而,在电子产品整体体积减小的情况下,市场及消费者仍希望产品的显示面积能不断增加,因此,如何在增加显示面板的显示面积的情况下同时保证其具有较小的体积已经是显示面板产品的大趋势。
目前,在TFT-LCD产品中主要通过封框胶粘合TFT基板和CF基板,从而在TFT基板和CF基板之间形成一个放置液晶及配向膜的密闭空间。现有的封框胶宽度根据产品尺寸大小不一,其宽度多数在1000微米左右,窄边框产品深受市场及消费者青睐,显示区域到玻璃边缘的距离越窄越受客户欢迎。但是,若简单采用减小封框胶的宽度来实现窄边框会引起封框胶对基板粘着力弱及外界气体穿刺等诸多问题。
因此,有必要提供一种液晶显示面板,以解决现有技术液晶显示面板边框较宽的问题。
【发明内容】

【附图说明】
为了更清楚地说明本发明实施例中的技术方案,下面将对实施例描述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发明的一些实施例,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。其中:
图1是本发明实施例的液晶显示面板的截面示意图;
图2是本发明实施例的液晶显示面板沿图1所示的A-A’方向的截面示意图;
图3是本发明实施例的液晶显示面板的第二基板的局部俯视图;以及
图4是图2中液晶显示面板的沟槽的放大截面示意图。
【具体实施方式】
下面结合附图和实施例对本发明进行详细说明。
参照图1-图2,图1是本发明实施例的液晶显示面板的截面示意图,图2是本发明实施例的液晶显示面板沿图1所示的A- A’方向的截面示意图。如图1-图2所示,本发明的液晶显示面板包括第一基板10、第二基板20以及封框胶30。
其中,第一基板10与第二基板20相对设置。第一基板10包括第一基板主体11以及设置于第一基板主体11上的第一表面层12,第二基板20包括第二基板主体21以及设置于第二基板主体21上的第二表面层22,第一表面层12和第二表面层22相邻设置。
在本实施例中,第一基板主体11和第二基板主体21分别为玻璃基板,而第一表面层12和第二表面层22分别包括透明导电层(例如,ITO层),其具体的制作方法及材料皆可参照现有技术,此处不再赘述。当然,在其他实施例中,第一表面层12和第二表面层22也可以包括其他功能层或省略。
封框胶30设置于第一基板10和第二基板20之间,并与二者接触,进而对第一基板10和第二基板20进行粘合固定。
第一基板10和第二基板20的相邻设置的两表面上设置有多个间隔设置的沟槽40。在本实施例中,在第一基板10的第一表面层12和第二基板20的第二表面层22形成过程中通过蚀刻工艺或其他适当工艺在封框胶30的涂布区域每间隔一段距离形成一个沟槽40,由此使得沟槽40间隔设置于第一表面层12和第二表面层22上,且沟槽40的深度优选等于第一表面层12或第二表面层22的厚度。在本实施例中,沟槽40的深度的取值范围优选为0.4微米~1.6微米。当然,在其他实施例中,沟槽40可仅设置于第一基板10和第二基板20中的任意一者上,且沟槽40可形成于第一基板10和第二基板20表面的其他功能层上或直接形成于第一基板主体11和第二基板主体21上,其沟槽40的深度可根据需要进行任意调整。
通过上述方式,可以使得封框胶30设置于沟槽40上并覆盖沟槽40,且封框胶30的一部分渗入沟槽40内,由此增加了封框胶30与第一基板10和第二基板20的接触面积,因此可在保证封框胶与基板粘着力的情况下有效减小封框胶的宽度,从而实现了液晶显示面板的超窄边框设计。
请进一步参考图3,图3是本发明实施例的液晶显示面板的第二基板的局部俯视图。下面将以第二基板20为例对沟槽40的具体设置方式进行详细描述。如图3所示,在本实施例中,封框胶30具有一长度方向X和一宽度方向Y,封框胶30在长度方向X上的尺寸大于封框胶30在宽度方向Y上的尺寸。多个沟槽40沿封框胶30的长度方向X间隔设置,且沿宽度方向Y延伸。当然,在其他实施例中,沟槽40的间隔方向和延伸方向也可以采用其他方式设置。
进一步,相邻两个沟槽40的沟槽中心之间的间距S的取值可根据需要进行调整。一般来说,为了实现第一基板10和第二基板20的同时接地,液晶显示面板进一步包括位于封框胶30所在区域的用于电连接第一基板10和第二基板20的导电垫50。为了保证导电垫50的良好导通,相邻两个沟槽40的沟槽中心之间的间距S优选小于或等于导电垫50在沟槽40的间隔方向上的尺寸的一半。目前,导电垫50的直径一般约为1400微米,因此间距S优选设置成小于或等于700微米。同时,为了保证曝光精度,沟槽40的宽度优选大于或等于5微米。
进一步参见图4,图4是图2中液晶显示面板的沟槽的放大截面示意图。如图4所示,根据表面膜形成原理(曝光原理)可知,沟槽40在沟槽40的间隔方向上的横截面为一个等腰梯形。通过计算得出,采用本发明的沟槽40的结构可多增加封框胶30与基板(第一基板10或第二基板20)接触面积的比率为:
[(c+d+e+b)-(a+b)]/(a+b)= (c+d+e-b)/(a+b)
其中,
a为沟槽40的上底边的宽度;
b为两相邻沟槽40之间的距离,且a+b=S;
c为沟槽40的下底边的宽度;
d和e为沟槽40的侧面长度,并可近似等于沟槽40的深度。
与不具有沟槽40的基板相比,以S=5微米,且d=e=1.5微米计算,封框胶30与一个基板表面的接触面积增加了约为1.5×2/5=60%,若第一基板10和第二基板20皆具有该沟槽40时,则将增加封框胶30与第一基板10和第二基板20表面的接触面积为120%。若S=700微米计算,则增加了封框胶30与一个基板表面的接触面积约为1.5×2/700=0.43%,若第一基板10和第二基板20皆具有该沟槽40时,则将增加封框胶30与第一基板10和第二基板20的接触面积为0.86%,即通过本发明的沟槽40的结构,封框胶30与第一基板10和第二基板20的接触面积可增加0.86%~120%不等。多增加的接触面积可使得本发明液晶显示面板在保证封框胶30对基板的粘着力不变的情况下缩短封框胶30,进而实现超窄边框的设计。
以现有技术能达到的封框胶30的最窄宽度约为900微米为例,以最大增大面积120%计算,根据公式900×5=(900-x)×(5+5×120%),得出x=490.9,即可以缩短封框胶30宽度为490.9微米,即与现有技术的液晶显示面板相比,本发明的液晶显示面板最多可以缩短54.5%的封框胶的宽度。
本发明的有益效果是:区别于现有技术的情况,本发明的液晶显示面板通过在基板表面的封框胶涂布区域增加沟槽结构来提高封框胶与基板的接触面积,以便能在保证封框胶与基板粘着力的情况下有效减小封框胶的宽度,从而实现了液晶显示面板的超窄边框设计。
以上所述仅为本发明的实施例,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
