本申请涉及显示技术领域,尤其涉及一种显示面板和显示装置。
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;
随着科技的进步,许多不同的显示设备,例如液晶显示器(Liquid Crystal Display,LCD)已广泛地应用于平面显示器,液晶显示器大部分为背光型液晶显示器,其是由液晶显示面板及背光模块(backlight module)所组成,液晶显示面板是由两片透明基板以及被封于基板之间的液晶盒所构成;而且,液晶盒中设有两种类型的支撑柱,一种高度较高的支撑柱为主支撑柱(main-PS),一种高度较低的支撑柱为副支撑柱(sub-PS)。主支撑柱与两个透明基板抵接,副支撑柱只与一个透明基板抵接,副支撑柱与主支撑柱之间的高度差形成对应的液晶盒厚。
目前,由于副支撑柱与主支撑柱之间的高度差较小,导致对应的液晶盒厚较小,容易产生气泡或液晶下部膨胀的问题。
发明内容
本申请的目的是提供一种显示面板和显示装置,以改善液晶盒中出现的气泡或液晶下部膨胀的问题。
本申请公开了一种显示面板,包括第一基板、第二基板、主支撑柱和副支撑柱,所述第一基板和第二基板对向设置;所述第二基板中对应所述主支撑柱位置形成第一区域,对应所述副支撑柱位置形成第二区域,所述第一区域的地势,高于所述第二区域的地势;其中,所述第一区域中膜层的数量,大于第二区域中膜层的数量。

本申请在不对主支撑柱的高度和副支撑柱的高度做变动,使所述副支撑柱和所述主支撑柱之间的高度差不变的情况下,通过改变副支撑柱和主支撑柱对应第二基板区域的膜层数量,增大副支撑柱与第二基板之间的间距,达到增大副支撑柱对应液晶盒厚高度的目的,从而增大了滴入式注入法窗口,改善了液晶盒中气泡和液晶下部膨胀的问题。

具体实施方式
需要理解的是,这里所使用的术语、公开的具体结构和功能细节,仅仅是为了描述具体实施例,是代表性的,但是本申请可以通过许多替换形式来具体实现,不应被解释成仅受限于这里所阐述的实施例。

此外,除非另有明确的规定和限定,术语“安装”、“相连”、“连接”应做广义理解,例如可以是固定连接,也可以是可拆卸连接,或一体地连接;可以是机械连接,也可以是电连接;可以是直接相连,也可以通过中间媒介间接相连,或是两个元件内部的连通。对于本领域的普通技术人员而言,可以根据具体情况理解上述术语在本申请中的具体含义。
如图1-2所示,是一种显示面板200平面和截面的示意图,显示面板200包括第一基板210(彩膜基板)、第二基板220(阵列基板)、主支撑柱230和副支撑柱240,所述主支撑柱230和副支撑柱240设置在所述第一基板210上,所述副支撑柱240和所述第二基板220的间距,等于所述副支撑柱240和所述主支撑柱230之间的高度差,这里不管是主支撑柱230还是副支撑柱240,对应的阵列基板中都与阵列基板的栅极212和源漏极215重叠,因此仅是利用主支撑柱230与副支撑柱240原始设计的高度不同,根据两者的高度差得到断差,所以主支撑柱230的高度大于副支撑柱240的高度多少,副支撑柱240对应液晶盒厚度Y就是多少。
在制作支撑柱时,常常会将支撑柱(Photo Spacer,PS)与显示面板200中相邻色阻之间的黑矩阵(Black Matrix,BM)通过一道制程形成,即BPS技术,也就是将BM+PS两张光罩用BPS一张光罩取代,这样不仅节省了一张光罩的费用,而且还使制成本下降。
但是由于通过BPS一般采用亚克力(Acryl)树脂材料,在制程中,先沉积完膜层,然后在膜层上形成负性光刻胶图案,照光后形成BPS图案,即同时形成支撑柱和黑矩阵,但是 BPS材料在光照的过程中会发生膜缩现象;而且BPS利用全色调掩膜(Full tone type)经一道曝光工艺形成,制作出的支撑柱有弹性且为岛状结构,易发生溢出,导致支撑柱图形变形,具体如图3所示,是利用BPS技术制作出的支撑柱分别在事先设计时的形状(上方的图,支撑柱为梯形),以及成型后形状对应的图型(下方的图,支撑柱为圆弧形)。
由于利用BPS技术制作的支撑柱容易变形,因此不能通过增大支撑柱高度的方法来增加主支撑柱230和副支撑柱240之间的段差,亦不能通过这种方法达到增大副支撑柱240对应液晶盒厚的目的。
如图4所示,是发明人提供的一种液晶量和液晶盒厚的关系示意图,在图4的直角坐标系中,横坐标表示液晶(LC)量,纵坐标表示液晶盒厚(Cell gap),图中可以看出随着液晶量的增大,液晶盒厚会逐渐增大;但是当液晶量过小的时候,液晶中会产生气泡,而当液晶量过大的时候会产生重力mura(液晶下部膨胀),影响LCD画面的均匀性和稳定性。因此液晶量和液晶盒厚需要保持在一个适合范围内,从而避免液晶量太少或太多导致的气泡和重力mura问题;其中,这一适合范围内液晶量的上限和下限也即滴入式注入法窗口(ODF window)。由于采用BPS技术的支撑柱容易变形,使得支撑柱难以做高,导致对应的液晶盒厚过小,容易导致液晶层中产生气泡,会造成移动色差,使得显示面板200的显示观感差。
基于此,本申请提供一种显示面板200和显示装置100,可以增大副支撑柱240对应的液晶盒厚,使得Cell gap增大,ODF window增大,改善由于支撑柱采用BPS技术而导致的液晶层中产生气泡,影响面板显示的问题。下面参考附图和可选的实施例对本申请作详细说明。
如图5-12所示,是一种显示面板200的示意图,作为本申请的一实施例,公开了一种显示面板200,显示面板200包括第一基板210、第二基板220、主支撑柱230和副支撑柱240,所述第一基板210和第二基板220对向设置;所述第二基板220中对应所述主支撑柱230位置形成第一区域250,对应所述副支撑柱240位置形成第二区域260;所述第一区域250的地势,高于所述第二区域260的地势;其中,所述第一区域250中膜层的数量,大于第二区域260中膜层的数量。
由于采用BPS技术形成的支撑柱容易变形,使得支撑柱的高度难以提高,从而限制了主支撑柱230和副支撑柱240之间的段差。本申请在不对主支撑柱230的高度和副支撑柱240的高度做变动,使所述副支撑柱240和所述主支撑柱230之间的高度差不变的情况下,通过改变副支撑柱240和主支撑柱230对应第二基板220区域的膜层数量,增大副支撑柱240与第二基板220之间的间距,达到增大副支撑柱240对应液晶盒厚高度的目的,从而增大了滴入式注入法窗口,改善了液晶盒中气泡和液晶下部膨胀的问题。
具体的,本申请在图1的基础上,在不改变支撑柱和副支撑柱240形状和位置的情况下, 方案通过改变副支撑柱240对应的膜层的地形、形状及厚度来增加副支撑柱240与第二基板220之间的高度,从而增加副支撑柱240对应液晶盒厚高度,进而减少气泡和移动色差的产生,提高显示面板200的显示效果;并且增大副支撑柱240对应液晶盒厚高度后,液晶滴入量范围也相应达到更大的范围,这样液晶的滴入量就更大,液晶饱和度就更高,从而提高显示面板200特性,使得显示面板200的观感效果好。
其中,所述第一基板210可以为彩膜基板,对应的所述第二基板220为阵列基板;所述第一基板210也可以为阵列基板,对应的所述第二基板220为彩膜基板。
当所述第一基板210可以为彩膜基板,对应的所述第二基板220为阵列基板时,所述主支撑柱230和副支撑柱240设置在所述彩膜基板靠近所述阵列基板的一侧,所述阵列基板包括依次堆叠设置的衬底211、栅极212、栅极绝缘层213、半导体层214、源漏极215、钝化层216和透明电极层217,所述主支撑柱230和透明电极层217抵接,所述副支撑柱240与所述透明电极层217之间未抵接,两者之间填充有液晶,形成对应的液晶盒厚。当然阵列基板还包括缓冲层和配向层等膜层,在此不一一列举。
所述阵列基板中对应所述主支撑柱230位置形成第一区域250,对应所述副支撑柱240位置形成第二区域260,所述第一区域250的地势,高于所述第二区域260的地势。如图5-10所示,分别是通过改变第二区域260的膜层位置和形状,使得第一区域250和第二区域260中阵列基板膜层数量不同,从而达到增大副支撑柱240与阵列基板间距的三种实施方式。
图5-6中,所述第一区域250包括依次堆叠的衬底211、栅极212、栅极绝缘层213、半导体层214、源漏极215、钝化层216和透明电极层217;所述第二区域260包括依次堆叠的衬底211、栅极绝缘层213、半导体层214、源漏极215、钝化层216和透明电极层217;所述第一区域250和所述第二区域260的地势之差为所述栅极212的厚度。本实施例中,副支撑柱240和阵列基板之间的间距Y,等于所述主支撑柱230与副支撑柱240的高度之差,加上所述栅极212的厚度;相对于图1中副支撑柱240和阵列基板之间的间距,等于所述主支撑柱230与副支撑柱240的高度之差来说,无疑增大了副支撑柱240对应的液晶盒厚,从而减少气泡和移动色差的产生,提高显示面板200的显示效果。而且,本实施例是通过将副支撑柱240对应栅极212位置做避空,这样还有利于提高显示面板200开口率。
图7-8中,所述第一区域250包括依次堆叠的衬底211、栅极212、栅极绝缘层213、半导体层214、源漏极215、钝化层216和透明电极层217;所述第二区域260包括依次堆叠的衬底211、栅极212、栅极绝缘层213、半导体层214、钝化层216和透明电极层217;所述第一区域250和所述第二区域260的地势之差为所述源漏极215的厚度。本实施例中,副支撑柱240和阵列基板之间的间距Y,等于所述主支撑柱230与副支撑柱240的高度之差,加上所述源漏极215的厚度;相对于图1中副支撑柱240和阵列基板之间的间距,等于所述 主支撑柱230与副支撑柱240的高度之差来说,无疑增大了副支撑柱240对应的液晶盒厚,从而减少气泡和移动色差的产生,提高显示面板200的显示效果。而且,本实施例是通过改变数据线的局部走线位置,使数据线局部弯曲,避免源漏极215与副支撑柱240重叠,这样增大了源漏极215与栅极212的重叠面积,有利于提高主动开关的驱动效果。
图9-10中,所述第一区域250包括依次堆叠的衬底211、栅极212、栅极绝缘层213、半导体层214、源漏极215、钝化层216和透明电极层217;所述第二区域260包括依次堆叠的衬底211、栅极绝缘层213、半导体层214、钝化层216和透明电极层217;所述第一区域250和所述第二区域260的地势之差,为所述源漏极215和所述栅极212的厚度之和。本实施例中,副支撑柱240和阵列基板之间的间距Y,等于所述主支撑柱230与副支撑柱240的高度之差,加上所述源漏极215和栅极212的厚度;相对于图1中副支撑柱240和阵列基板之间的间距,等于所述主支撑柱230与副支撑柱240的高度之差来说,无疑极大地增大了副支撑柱240对应的液晶盒厚,进一步减少了气泡和移动色差的产生,提高显示面板200的显示效果。而且,本实施例是通过同时对栅极212做避空设计,并改变数据线的局部走线位置,使数据线局部弯曲,来达到增大副支撑柱240对应的液晶盒厚的目的,因此同时具备上述提高显示面板200开口率、提高主动开关的驱动的综合效果。
进一步的,在上述多个实施例中,所述栅极212和源漏极215采用加厚设计,具体的,栅极212和源漏极215采用双铝或双铜制程,并且膜厚在3000-5500埃米之间。通过这样的设计,能够进一步提高副支撑柱240对应的液晶盒厚,进一步改善气泡问题;并且还可以减小电阻电容负载(RC loading,Resistance Capacitor loading),因为由电容公式C=ε0εrA/d可知,其中,ε为介电常数,其中A为面积,d为膜层厚度。可知d越小,则电容越大,而电容越大,则电容负载也就越大。因此,通过增大栅极212和源漏极215的厚度,还能够达到改善电阻电容负载的问题。
如图11所示,所述阵列基板还包括色阻层218、遮光层219和平坦层222,所述色阻层218和遮光层219设置在所述钝化层216远离所述半导体层214的一侧,所述平坦层222设置在所述色阻层218和遮光层219远离所述钝化层216的一侧,所述透明电极层217设置在所述平坦层222所述色阻层218和遮光层219的一侧。本实施例可以基于上述多个实施例的进一步改进,将彩膜基板中的色阻层218做到阵列基板上,这一技术为COT(color filter on TFT)或是COA(color filter on Array)技术,其好处可以提升画素开口率并降低移动色差(movable mura)的发生机率,并且还可以进一步减小电阻电容负载;另外COT或COA技术更容易与BPS技术结合使用,因此更加需要增加副支撑柱240对应的液晶盒厚。
其中,所述遮光层219由色阻层218中的色阻堆叠而成,这样减小了遮光层219的制程步骤,提高生产效率;且所述主支撑柱230的正投影与所述遮光层219重叠,所述副支撑柱 240的正投影与所述色阻层218重叠,所述遮光层219至少由两种不同颜色的色阻堆叠而成,每层色阻的厚度都与色阻层218的厚度相同,此时副支撑柱和阵列基板之间的间距Y,最少等于色阻层的高度与两种支撑柱之间的高度差之和,这样使得第一区域250与第二区域260的高度差进一步扩大,进一步减小液晶中气泡产生的几率。
当然本申请还可以通过改变第一区域250和第二区域260中膜层的厚度来达到增大副支撑柱240对应液晶盒厚的目的,具体可以增加第一区域250中膜层的厚度,也可以减小第二区域260中膜层的厚度,其中不仅可以改变阵列基板中膜层的厚度,还可以改变彩膜基板中膜层的厚度。
如图12所示,是一种减小第二区域260中膜层厚度的设计,在第一区域250中膜层的数量大于第二区域260中膜层的数量的前提下,所述第二区域260设有挖槽221,所述第一区域250和所述第二区域260的地势之差为所述挖槽221的深度,即副支撑柱与阵列基板之间的间距Y为主支撑柱和副支撑柱之间的间距,与挖槽的深度之和。本实施例是通过减小阵列基板中与副支撑柱240重叠膜层的厚度,来达到增大副支撑柱240对应液晶盒厚的目的;本实施例只是将与副支撑柱240重叠的膜层做薄,并不用将整道膜层做薄,并不影响膜层的整体性能;进一步的,本实施例是将钝化层216的厚度做薄,由于钝化层216的膜层较厚,因此挖槽221设置在钝化层216中的话,可以增大挖槽221的深度,使得第一区域250和所述第二区域260的地势差增大。另外,本实施例还可以同时对第二区域260中多个膜层同时进行挖槽221设计,进一步增大第一区域250和所述第二区域260的地势差。
如图13所示,在另一实施例中,所述第一基板210为彩膜基板,所述第二基板220为阵列基板,所述主支撑柱230和副支撑柱240设置在所述阵列基板靠近所述彩膜基板的一侧,所述阵列基板对应所述主支撑柱230位置形成第一区域250,对应所述副支撑柱240位置形成第二区域260;所述阵列基板中第一区域250的膜层数量,大于第二区域260的膜层数量;具体的,本实施例中阵列基板第一区域250和第二区域260的设计,可以与图5-12对应实施例中阵列基板第一区域250和第二区域260的设计相同。
如图14所示,在另一实施例中,所述第一基板210为阵列基板,所述第二基板220为彩膜基板,所述主支撑柱230和副支撑柱240设置在所述阵列基板靠近所述彩膜基板的一侧,所述主支撑柱230与彩膜基板抵接,所述副支撑柱240与所述彩膜基板之间不抵接,两者之间填充有液晶,形成对应的液晶盒厚;所述彩膜基板中对应所述主支撑柱230位置形成第一区域250,对应所述副支撑柱240位置形成第二区域260;所述第一区域250的地势,高于所述第二区域260的地势;其中,所述第一区域250中膜层的数量,大于第二区域260中膜层的数量。
在本实施例中,通过改变彩膜基板中第一区域250和第二区域260的膜层数量,使得副 支撑柱240和彩膜基板之间的间距,大于主支撑柱230和副支撑柱240之间的段差;例如可以将副支撑柱240做到黑矩阵290靠近所述阵列基板的一侧,而将主支撑柱做到色阻层218靠近所述阵列基板的一侧;从而减少气泡和移动色差的产生,提高显示面板的显示效果。
另外,还可以通过改变阵列基板中栅极212和源漏极215的走线形状和位置,以及其它膜层中与主支撑柱230、副支撑柱240的膜厚,这些方案来提高副支撑柱240与彩膜基板之间的间距;另外,还通过改变彩膜基板中膜层的厚度,例如可以在第四区域280中做挖槽,或者在第三区域270中做凸起,来进一步增大第三区域270和第四区域280的段差。
如图15所示,在另一实施例中,所述第一基板210为阵列基板,所述第二基板220为彩膜基板,所述主支撑柱230和副支撑柱240设置在所述彩膜基板靠近所述阵列基板的一侧,主支撑柱230与所述阵列基板抵接,所述副支撑柱240与所述阵列基板之间不抵接,两者之间填充有液晶,形成对应的液晶盒厚;所述彩膜基板中对应所述主支撑柱230位置形成第一区域250,对应所述副支撑柱240位置形成第二区域260;所述第一区域250的地势,高于所述第二区域260的地势;其中,所述第一区域250中膜层的数量,大于第二区域260中膜层的数量。
当然本申请中还可以改变主支撑柱和副支撑柱的位置,而不改变第一基板210或第二基板220的膜层结构,来达到主支撑柱230和副支撑柱240对应不同膜层的效果。
作为本申请的另一实施例,如图14所示,还公开了一种显示装置100,包括如上所述的显示面板200,以及为所述显示面板200提供背光源的背光模组300。采用本实施例提供的显示装置100,不会在液晶中产生气泡,且液晶的滴入量较多,在显示过程中能够提供良好的显示效果。
需要说明的是,本申请的发明构思可以形成非常多的实施例,但是申请文件的篇幅有限,无法一一列出,因而,在不相冲突的前提下,以上描述的各实施例之间或各技术特征之间可以任意组合形成新的实施例,各实施例或技术特征组合之后,将会增强原有的技术效果
以上内容是结合具体的可选实施方式对本申请所作的进一步详细说明,不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说,在不脱离本申请构思的前提下,还可以做出若干简单推演或替换,都应当视为属于本申请的保护范围。
