本申请要求2018年12月05日申请的,申请号为201822035652.5名为“显示面板和显示装置”的中国专利申请优先权,在此将其全文引入作为参考。
技术领域
本申请涉及显示面板封装技术领域,特别涉及一种显示面板和应用该显示面板的显示装置。
背景技术
这里的陈述仅提供与本申请有关的背景信息,而不必然地构成现有技术。
液晶显示器包括相对的上下基板,上基板主要由红绿蓝三种色阻组成的矩阵以及作为共电极的氧化铟锡(ITO,或者掺锡氧化铟)组成,下基板上有金属线路以及晶体二极管组成的矩阵。液晶夹在相对的两基板之间,通过上下基板上的ITO电极的压差,控制液晶分子的转动,从而控制显示面板的亮暗显示。其中上下基板由涂布在其中一个基板四周的封框胶粘合成盒。
在制程的初始阶段,液晶分子为杂乱无章的状态,需要配向膜做初始的定向排布。基板具有显示区域和非显示区域,在制作配向膜时,需要将液态的配向膜材料涂布在基板的显示区域,同时还要防止液态的配向膜材料流动至封框胶处,影响封框胶粘着性,最终影响上下基板的封闭性。因此,示例性的设置一般在封框胶靠近显示区域的一侧设计竖直设置的挡墙阻挡液态的配向膜材料与封框胶混合。然而竖直的挡墙阻挡液态的配向膜材料外流的同时也使液态的配向膜材料撞击挡墙产生回流,从而使基板边缘没有配向膜材料的分布导致显示面板的四周边缘显示异常,同时回流的配向膜液体材料也会造成有效显示区域的显示异常。
申请内容
本申请的主要目的是提供一种显示面板和显示装置,旨在防止显示面板的出现显示异常。
为实现上述目的,本申请提出的显示面板,包括:
基板,所述基板包括有效显示区域和围绕所述有效显示区域的非显示区域;
配向膜,所述配向膜设于所述有效显示区域;
封框胶,所述封框胶设于所述非显示区域;以及
至少一排挡墙,所述挡墙设于所述配向膜和所述封框胶之间,所述挡墙包括多段分挡墙,多段所述分挡墙间隔排布形成而具有凸出部和凹陷部。
在本申请的一实施例中,所述凸出部包括一横向分挡墙和两倾斜分挡墙,该横向分挡墙靠近所述配向膜设置,两所述倾斜分挡墙位于所述横向分挡墙的朝向所述封框胶的一侧;
两所述倾斜分挡墙沿所述横向分挡墙的第一方向间隔相对设置形成让位间隙,一所述横向分挡墙设于该让位间隙;

在本申请的一实施例中,两相邻所述倾斜分挡墙的倾斜方向相反。
在本申请的一实施例中,定义与所述第一方向的垂直方向为第二方向,所述倾斜分挡墙在所述竖直方向上所形成的夹角α的范围为:0°≤α<90°。
在本申请的一实施例中,两相邻所述倾斜分挡墙的倾斜角度相同。
在本申请的一实施例中,在所述凸出部中,所述倾斜分挡墙的最高点与所述横向分挡墙的下表面所在的平面之间的垂直距离H1的范围值为0μm<H1≤100μm。
在本申请的一实施例中,在所述凹陷部中,所述倾斜分挡墙的最低点与所述横向分挡墙的上表面所在的平面之间的垂直距离H2的范围值为0μm<H2≤100μm。
在本申请的一实施例中,所述分挡墙的长度L1的范围值为10μm至500μm。
在本申请的一实施例中,每一所述分挡墙的长度相等。
在本申请的一实施例中,所述挡墙的材质为聚苯乙烯;
在本申请的一实施例中,所述配向膜的材质为聚酰亚胺。
本申请还提出一种显示装置,包括显示面板,所述显示面板包括:
基板,所述基板包括有效显示区域和围绕所述有效显示区域的非显示区域;
配向膜,所述配向膜设于所述有效显示区域;
封框胶,所述封框胶设于所述非显示区域;以及
至少一排挡墙,所述挡墙设于所述配向膜和所述封框胶之间,所述挡墙包括多段分挡墙,多段所述分挡墙间隔排布形成而具有凸出部和凹陷部。
本申请还提出一种显示装置,包括显示面板,显示面板包括:
基板,所述基板包括有效显示区域和围绕所述有效显示区域的非显示区域;所述基板为数组基板和彩膜基板的至少之一;
配向膜,所述配向膜设于所述有效显示区域;

本申请技术方案通过采用在配向膜和封框胶之间设置挡墙,从而防止配向膜液体与封框胶接触。同时,通过将挡墙设置为多段设置的分挡墙,该多段设置的分挡墙排布形成凸出部和凹陷部。配向膜的液体在流向凸出部时,会经由凸出部侧边的分挡墙流向凹陷部,在凹陷部处汇集。如此,配向膜的液体不会回流,使得有效显示区域的显示正常。同时,因为凸出部和凹陷部的阻挡和汇集,配向膜的液体也不会与封框胶接触。从而可以有效防止显示面板的显示异常。

本申请提出一种显示面板100,应设置为显示装置。
参照图1至3,在本申请实施例中,该显示面板100包括:
基板10,基板10包括有效显示区域和围绕有效显示区域的非显示区域;
在本申请的一实施例中,基板10为数组基板和彩膜基板的至少之一。
也即,该基板10可为上基板(彩膜基板),彩膜基板主要由红绿蓝三种色阻组成的矩阵以及作为共电极的ITO组成。该基板10也可为下基板(数组基板),数组基板上有金属线路以及晶体二极管组成的矩阵。本申请的基板10其厚度可设置为0.4mm至0.7 mm,从而使得基板10的厚度更薄,进而使得显示面板100的整体厚度变薄。基板10采用玻璃基板,基板玻璃可分为碱玻璃及无碱玻璃两大类。碱玻璃包括钠玻璃及中性硅酸硼玻璃两种,多应设置为TN(twisted nematic,扭转式向列场效应)及STN LCD(Super Twisted Nematic,超扭曲向列型)上,以浮式法制程生产为主。无碱玻璃则以无碱硅酸铝玻璃(Alumino Silicate Glass,主成分为SiO2、Al2O3、B2O3及BaO等)为主,其碱金属总含量在1%以下,主要设置为TFT- LCD上。
有效显示区域(Active Area),指的是基板10能够显示文字图像的区域,可设置在基板10的中部区域。非显示区域,指的是不能够显示显示文字图像的区域,一般环绕有效显示区域设置。该处布置电路走线及其他驱动的电子元器件。
配向膜30,配向膜30设于有效显示区域;
配向膜30(alignment film),配向膜30是具有直条状刮痕的薄膜,作用是引导液晶分子的排列方向。例如在已镀上透明导电膜(ITO)的玻璃基板10上,用PI涂液和转轮(roller),在ITO膜上印出一条一条平行的沟槽,到时候液晶可依此沟槽的方向横躺于沟槽内,达到使液晶呈同一方向排列之目的。
配向膜30的材料需要具备良好的光穿透性;必须为离子化存在或部分离子化的;拥有共价或部分共价的链结;非晶形以及良好的晶格结构。
主要使用的无机材料有:DLC(DLC是英文“DIAMOND-LIKE CARBON”一词的缩写。DLC是一种由碳元素构成、在性质上和钻石类似,同时又具有石墨原子组成结构的物质。类金刚石薄膜是一种非晶态薄膜,具有高硬度和高弹性模量,低摩擦因数,耐磨损以及良好的真空摩擦学特性)、SiC、SiO2、glass、Si3N4、Al2O3、CeO2 、ZnTiO2 等。主要有机材料有:PI(Polyimide,聚酰亚胺)、PVC(PVC全名为Polyvinylchloride,主要成份为聚氯乙烯)、PMMA(PMMA全名为PolymethylMethacrylate,主要成份为聚甲基丙烯酸甲酯)等。
本申请可选使用聚酰亚胺,聚酰亚胺是指主链上含有酰亚胺环(-CO-NH-CO-)的一类聚合物,其中以含有酞酰亚胺结构的聚合物最为重要。聚酰亚胺作为一种特种工程材料,已广泛应用在航空、航天、微电子、纳米、液晶、分离膜、激光等领域。聚酰亚胺具有如下优点:开始分解温度一般都在500℃左右。由均苯四甲酸二酐和对苯二胺合成的聚酰亚胺,热分解温度达600℃,是迄今聚合物中热稳定性最高的品种之一。聚酰亚胺还可耐极低温,如在-269℃的液态氦中不会脆裂。聚酰亚胺具有优良的机械性能,未填充的塑料的抗张强度都在100Mpa以上,均苯型聚酰亚胺的薄膜(Kapton)为170Mpa以上,而联苯型聚酰亚胺(Upilex S)达到400Mpa。作为工程塑料,弹性模量通常为3-4Gpa,纤维可达到200Gpa,据理论计算,均苯四甲酸二酐和对苯二胺合成的纤维可达 500Gpa,仅次于碳纤维。一些聚酰亚胺品种不溶于有机溶剂,对稀酸稳定,一般的品种不大耐水解,这个看似缺点的性能却使聚酰亚胺有别于其他高性能聚合物的一个很大的特点,既可以利用碱性水解回收原料二酐和二胺,例如对于Kapton薄膜,其回收率可达80%-90%。改变结构也可以得到相当耐水解的品种,如经得起120℃,500 小时水煮。聚酰亚胺具有很高的耐辐照性能,其薄膜在5×109rad快电子辐照后强度保持率为90%。 聚酰亚胺具有良好的介电性能,介电常数为3.4左右,引入氟,或将空气纳米尺寸分散在聚酰亚胺中,介电常数可以降到2.5左右。介电损耗为10-3,介电强度为100-300KV/mm,广成热塑性聚酰亚胺为300KV/mm。这些性能在宽广的温度范围和频率范围内仍能保持在较高的水平。聚酰亚胺是自熄性聚合物,发烟率低。聚酰亚胺在极高的真空下放气量很少。聚酰亚胺无毒,有一些聚酰亚胺还具有很好的生物相容性。
封框胶50,封框胶50设于非显示区域;
封框胶50是一种胶粘剂,将LCD液晶屏上下两片基板10粘接起来,同时保持一定的间隙,然后将灌入的液晶密封起来,使其不能渗漏,同时防止外界污染物进入,这种胶粘剂即封框胶50,也称作封边胶。LCD液晶屏用封框胶50主要有两大类:热固化胶和紫外光(UV)固化胶。两种胶主要区别在于其固化方式的不同。热固化胶应用比较广泛。但制作高精度的液晶显示屏,UV固化胶在固化时间,接着力,耐湿力,耐热性等各方面均优于热固化胶。尤其固化时间短,缩短了生产周期,同时防止了在长时间固化过程中两片玻璃的错位。本申请可选UV固化胶,成分为变性丙烯酸脂类化合物,外观为微黄色粘稠液体。在工作时,使胶状的UV固化胶均匀涂布在上片玻璃表面边框位置,上下两片基板10粘合后,用紫外光照射使胶由线型大分子结构相互交联为稳定的网状结构,具有很强的粘附能力,使两片基板10粘合在一起。
以及至少一排挡墙70,挡墙70设于配向膜30和封框胶50之间,挡墙70包括多段分挡墙,多段所述分挡墙间隔排布形成而具有凸出部71和凹陷部73。
本申请技术方案通过采用在配向膜30和封框胶50之间设置挡墙70,从而防止配向膜30液体与封框胶50接触。同时,通过将挡墙70设置为多段设置的分挡墙,该多段设置的分挡墙排布形成凸出部71和凹陷部73。配向膜30的液体在流向凸出部71时,会经由凸出部71侧边的分挡墙流向凹陷部73,在凹陷部73处汇集。如此,配向膜30的液体不会回流,使得有效显示区域的显示正常。同时,因为凸出部71和凹陷部73的阻挡和汇集,配向膜30的液体也不会与封框胶50接触。从而可以有效防止显示面板100的显示异常。
多段分挡墙的形状和结构设置可为相同,也可为不同。其形状设置可为长方体,以方便加工。也可以为其他形状,如弧状结构或波浪形结构。弧状结构何为圆弧的一部分,例如为劣弧状,其圆心位于有效显示区域的一侧,因此,该弧状结构也可为容纳配向膜30的液体的存储空间。
本申请一实施例中,为了方便加工设计设置,将每一分挡墙的长度设计为相等。当然,在本申请的领一实施例中,还可以将分挡墙的长度设计为不等。如此,可实现分挡墙差异化的设计排布。
在本申请的一实施例中,还可设置多排挡墙70,每一排挡墙70均设置凸出部71和凹陷部73,相邻两排挡墙70的凸出部71相对应,相邻两排挡墙70的凹陷部73相对应,如此多排挡墙70的设置可更好地阻拦配向膜30液体,并防止配向膜30液体的回流。
结合参照图2和图3,在本申请的一实施例中,凸出部71包括一横向分挡墙75和两倾斜分挡墙77,该横向分挡墙75靠近配向膜30设置,两倾斜分挡墙77位于横向分挡墙75的朝向封框胶50的一侧;
两倾斜分挡墙77沿横向分挡墙75的第一方向间隔相对设置形成让位间隙,一横向分挡墙75设于该让位间隙;
凹陷部73包括一横向分挡墙75和两倾斜分挡墙77,该横向分挡墙75靠近封框胶50设置,两倾斜分挡墙77位于横向分挡墙75的朝向配向膜30的一侧;
两倾斜分挡墙77沿横向分挡墙75的第一方向间隔相对设置形成让位间隙,一横向分挡墙75设于该让位间隙。
该第一方向为横向分挡墙的长度方向,通过横向分挡墙75,进行阻隔液态的配向膜30材料,防止液态的配向膜30材料与封框胶50接触。通过倾斜分挡墙77,起到阻隔且导引的作用,液态的配向膜30材料被倾斜分挡墙77阻隔并导引,防止液态配向膜30材料回流。因此由横向分挡墙75和倾斜分挡墙77形成的凸出部71和凹陷部73,能够较好的阻隔液态配向膜30材料的流动,并防止其回流。凸出部71和凹陷部73可邻接并交替设置,可共用同一个倾斜分挡墙77,如此简化结构设计。
进一步地,两相邻倾斜分挡墙77的倾斜方向相反。
通过将两相邻的倾斜分挡墙77的倾斜方向设置为相反,可更好地实现阻隔、导流的作用。
在本申请的一实施例中,定义与第一方向的垂直方向为第二方向,倾斜分挡墙77在竖直方向上所形成的夹角α的范围为:0°≤α<90°。
此处的第二方向即为横向分挡墙的宽度方向。夹角α等于0度时,配向膜30液体在流动时会减小与倾斜分挡墙(此时称之为倾斜分挡墙,只是为了区分与横向分挡墙的称呼,可以理解的是,该倾斜分挡墙可以称之为竖直分挡墙)的接触。
将夹角α设置为锐角,即角度设置为0°<α<90°,在配向膜30液体流动的方向,在形成为凸出部71时,可更好地导引配向膜30液体。在形成凹陷部73时,在更好地导引配向膜30液体的同时,还能够形成更大的存储配向膜30液体的空间。
进一步地,两相邻所述倾斜分挡墙77的倾斜角度相同。如此可方便加工设计,可选设置为倾斜角度为45度。
参照图3,在本申请的一实施例中,在凸出部71中,倾斜分挡墙77的最高点与横向分挡墙75的下表面所在的平面之间的垂直距离H1的范围值为0μm<H1≤100μm;
且/或,在凹陷部73中,倾斜分挡墙77的最低点与横向分挡墙75的上表面所在的平面之间的垂直距离H2的范围值为0μm<H2≤100μm。
也即,在凸出部71中,倾斜分挡墙77的最高点与横向分挡墙75的下表面之间形成间隙,该间隙不易过大,过大会使得倾斜分挡墙77和横向分挡墙75之间通过较多的配向膜30液体。例如可以设置为1μm、10μm、15μm、20μm、30μm、40μm、50μm、60μm、70μm、80μm、90μm、100μm。
参照图3,在本申请的一实施例中,分挡墙的长度L1的范围值为10μm至500μm。
分挡墙的长度不宜过长,过长会使得配向膜30液体在接触该分挡墙后回流,影响有效显示区域部位的显示。当然,分挡墙也不宜过短,过短无法有效阻止配向膜30的液体,使得配向膜30的液体与封框胶50接触,影响封框胶50的粘结性能。同时,还要考虑到设置空间的大小。因此,分挡墙的长度设置为10μm至500μm,例如可以设置为10μm、20μm、50μm、80μm、100μm、150μm、200μm、300μm、400μm、500μm。
在本申请的一实施例中,分挡墙的宽度的范围值为5μm至50μm。
分挡墙的宽度不宜过宽,过宽会占用较多的空间,也不宜过窄,过窄不方便加工设计。因此,分挡墙的宽度设置为5μm至50μm,例如可以设置为5μm、10μm、15μm、20μm、30μm、40μm、50μm。每一分挡墙的宽度可设置为相同,也可设置为不同,可根据具体情况设置。
本申请还提出一种显示装置,该显示装置包括显示面板100,该显示面板100的具体结构参照上述实施例,由于本显示装置采用了上述所有实施例的全部技术方案,因此至少具有上述实施例的技术方案所带来的所有效果,在此不再一一赘述。该显示装置可以为液晶电视,移动终端(例如智能手机,平板电脑,手持PDA)或者为笔记本电脑等。
以上所述仅为本申请的可选实施例,并非因此限制本申请的专利范围,凡是在本申请的申请构思下,利用本申请说明书及附图内容所作的等效结构变换,或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
