Description

一种显示面板及显示装置
本申请要求于2018年9月21日提交中国专利局，申请号为201821556456.6，发明名称为“一种显示面板及显示装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请属于显示技术领域，特别涉及一种显示面板及显示装置。
背景技术
这里的陈述仅提供与本申请有关的背景信息，而不必然构成现有技术。液晶面板主要包括彩色滤膜(Color Filter，CF)基板和薄膜晶体管(Thin Film Transistor,TFT)基板，二者间隔一定距离对接且密封周边形成液晶盒，液晶盒内填充液晶分子。液晶面板设有黑色间隙光阻(BPS,Black photo spacer)，其包括遮光层及间隔物，遮光层用于遮挡不宜外露的电路结构，间隔物用于支撑液晶盒的盒厚稳定。间隔物有两种，即主间隔物和辅间隔物(Main BPS&Sub BPS)，主间隔物与辅间隔物与TFT基板之间的距离不同，进而产生段差。主间隔物用于在正常情况下维持液晶盒厚，辅间隔物用于液晶受冷收缩时维持液晶盒厚。
液晶材料会受温度影响发生热胀冷缩，当温度过高时，液晶体积膨胀，主间隔物支撑力减小，液晶膨胀后会局部聚集在一起出现重力Mura(因重力产生的亮度不均、斑点)，定义出现重力Mura的边界液晶量为L1；当温度过低时，液晶体积缩小，盒厚变小，辅间隔物产生支撑力，阻止液晶盒厚的进一步下降，此时局部空间仍有可能因无液晶而出现真空气泡，定义出现真空气泡的边界液晶量为L2。在L1与L2之间的液晶量，为液晶冗余(LC margin)，在此范围内不会出现重力mura与真空气泡。当段差过小时，无法保证液晶冷缩后仍能够充满 液晶盒，进而易产生真空气泡，使得LC margin过小，合适的段差是保证足够大的LC margin的必要条件，也是提升液晶显示面板品质的重要因素。
范例技术中有通过特殊光罩来制作不同高度间隔物而产生段差，但是因光阻本身感光性较差，做出来的段差均匀性不好,导致LC margin较小。因此需要提供一种新的解决方案，来改善段差的均匀性，以获得较大的段差。

为了说明本申请所述的技术方案，以下结合具体附图及实施例进行详细说明。
请参阅图1至图4，本实用新型实施例提供一种显示面板100，是一种能够增大段差的显示面板，包括第一基板1和第二基板2，第一基板1包括第一基层11以及设置于第一基层11上的遮光层12、主间隔物13和辅间隔物14，第二基板2至少包括第二基层21、设置于第二基层21上的介质层22以及驱动电路23，驱动电路23包括设置于介质层22中的驱动电极231和设置于介质层22表面的画素电极232，介质层22对应每个画素电极232均开设有用于导通画素电极232和驱动电极231的过孔24；其中，辅间隔物14与过孔24正对，主间隔物13不与过孔24正对，主间隔物13与辅间隔物14的高度相同，可以采用同一光罩工序一次制成。在自然状态下，主间隔物13的顶部与第二基层21的介质层22表面平齐，辅间隔物14与过孔24之间存在间隙。当液晶分子受冷收缩时，第二基层21和第一基层11相互靠近，第一基板1和第二基板2的间隙变薄，辅间隔物14嵌入过孔24触碰过孔24的底壁或者侧壁，对第一基板1和第二基板2的间隙起到支撑作用。辅间隔物14能够嵌入过孔24的最大深度为该液晶面板的段差。
可以理解，第二基层21和第一基层11的变形量存在一定临界值，即盒厚的变化空间具有一定界限，当液晶分子收缩到一定程度时，第二基层21和第一基层11达到最大变形量，无法继续压缩，此时随着液晶分子的进一步收缩，可能出现真空气泡。在这种情况下，辅间隔物14若仍然未接触过孔24的底壁或者侧壁，则不能起到支撑液晶盒间隙的作用。因此，本实施例中的过孔24深度以及辅间隔物14的高度能够满足在低温情况下的辅间隔物14能够接触过孔24的底壁或者侧壁以支撑盒厚，一般地，该段差的范围可以是0.4-0.8mm。
本实用新型实施例提供的显示面板将第一基板1的辅间隔物14与第二基板2的过孔24正对，辅间隔物14的顶部与过孔24的底部之间存在一定间隙， 使得辅间隔物14在液晶分子低温收缩时能够嵌入过孔24一定深度，该可嵌入的最大深度即为段差，在温度较低时，可以通过辅间隔物14与过孔24内壁的接触实现对液晶盒的支撑。这样，主间隔物13和辅间隔物14可以在同一制程中一次成型，高度和整体结构一致性好，避免辅间隔物14高度不一致导致的有效段差减小，同时辅间隔物14与过孔24正对也使段差得以增大，进而保证较大的LC margin。并且，不需增加制程，不增加掩膜板，能够保证较高的生产效率。
在一个实施例中，与辅间隔物14正对的过孔24的宽度大于其他过孔24的宽度，这样有利于容置辅间隔物14，并且，其他过孔24的宽度只要能够满足电流导通即可，无需设置较宽。
在一个实施例中，与辅间隔物14正对的过孔24的底部宽度大于或等于辅间隔物14的顶部宽度，使得辅间隔物14能够接触到过孔24的底部，实现最大的段差。
可选地，辅间隔物14和过孔24的形状一致，但过孔24的宽度略大于辅间隔物14的宽度，过孔24的深度可以大于、等于或者小于辅间隔物14的高度。
具体地，该过孔24的形状优选为底部窄顶部宽的锥形孔，或者是直径一致的柱形孔。
在一个实施例中，当采用锥形的过孔24时，辅间隔物14的顶部宽度可以大于过孔24的底部宽度，辅间隔物14的顶部接触锥形过孔24的靠近底部的侧壁时，也能够起到支撑作用。当过孔24为直径一致的柱形孔时，辅间隔物14的顶部宽度要求不大于过孔24的直径。当然，对于任意形状的过孔24，辅间隔物14的顶部宽度小于过孔24的底部宽度均为可行的方案。
在本实施例中，第一基层11主要用于提供液晶盒间隙的一部分支撑，第二基层21主要用于提供液晶盒的另一部分支撑以及控制液晶分子的偏转，以结合色阻结构调节像素的色彩及明暗。当然，作为完整的液晶盒，第一基层11和第二基层21的侧边需要通过密封结构进行密封。
参考图1至图4，介质层22包括用于保护驱动电路23的保护层221和设置于保护层221上的色阻层222，画素电极232设置于色阻层222上；色阻层222包括多组画素色阻，每组画素色阻包括红、蓝、绿三种颜色的色阻单元2221，或者包括红、蓝、绿、白四种颜色的色阻单元2221，画素电极232与色阻单元2221一一对应。第一基层11上设有透明导电膜15，该透明导电膜15与第二基层的画素电极232为液晶分子提供偏转电压。以三原色像素为例，每组画素色阻包括一个红光色阻单元、一个绿光色阻单元和一个蓝光色阻单元，分别对应一个画素电极。其中，红光色阻单元及其表面的画素电极、透明导电膜15与其正对的部分，以及二者之间的液晶分子构成一个红色子像素，绿光色阻单元及其表面的画素电极，透明导电膜15与其正对的部分，以及二者之间的液晶分子构成一个绿色子像素，蓝光色阻单元及其表面的画素电极、透明导电膜15与其正对的部分，以及二者之间的液晶分子构成一个蓝色子像素，三个子像素构成一个完整的像素。同理，可以增加白光子像素，由四个子像素构成一个像素。
可选地，参考图9，第二基层21与保护层221之间还设有公共电极层25。第一基板1和第二基板2的周边通过导电封胶3密封，导电封胶3导通透明导电膜15和公共电极层25，以形成存储电容。
参考图1和图5，保护层221包括第一保护层2211和第二保护层2212，驱动电路23还包括设置于第二基层21和第一保护层2211之间的扫描线233， 以及设置于第一保护层2211和第二保护层2212之间的数据线234，该过孔24贯通色阻层222和第二保护层2212，画素电极232、扫描线233和数据线234均与驱动电极231电连接。驱动电极231是一种半导体器件，半导体器件具有源极、栅极和漏极，而画素电极232、扫描线233和数据线234分别连接于半导体器件的三个电极，用于为画素电极232施加电压。
在一个实施例中，在画素电极232的表面还设有上配向膜，在第一基板1的透明导电膜15的表面还设有下配向膜，上配向膜和下配向膜用于控制液晶分子的取向。
在本实施例中，遮光层12、主间隔物13和辅间隔物14可以采用黑色油墨通过一道光罩制程一次制成，效率高且一致性好。参考图3和图5，遮光层12设置于第一基层11表面，用于遮盖驱动电路23、主间隔物13及辅间隔物14等不宜被用户看到的结构，主间隔物13和辅间隔物14位于遮光层12的区域内，不会影响可视区的面积，同时，遮光层12为矩阵结构，在不同色阻单元2221之间形成隔离带，对色阻单元2221之间的线路以及相邻色阻单元2221的交接处进行遮挡。
在一个实施例中，相邻色阻单元2221可以通过边部叠加，形成叠加部2222，该叠加部2222使得相邻色阻单元2221之间无缝隙，避免产生气泡。另外，叠加部2222的位置通常对应着驱动电路的位置，同时，该处的光线易混色，因此其宽度小于遮光层12的宽度，即至少保证遮光层12能够遮挡叠加部2222，在驱动电路23所占区域大于叠加部2222的宽度的情况下，该遮光层12要能够遮挡驱动电路23的宽度。
在其他实施例中，相邻色阻单元2221可以间隔一定间隙，该间隙的宽度以不产生气泡为宜。
继续参考图1，作为主间隔物13和辅间隔物14的一个实施例，主间隔物13和辅间隔物14的数量为多个，例如各为2个、3个至几十个不等，甚至其总数量接近或等于色阻单元的数量。可选地，主间隔物13和辅间隔物14数量相等。
关于主间隔物13和辅间隔物14的分布方式：
在第一个实施例中，主间隔物13和辅间隔物14分设于不同色阻单元2221对应的区域。任意一个色阻单元2221至多设置一个主间隔物13或者一个辅间隔物14。可选地，参考图3和图6，一个主间隔物13设置于一个色阻单元2221对应的区域，一个辅间隔物14设置于相邻的另一个色阻单元2221对应的区域。例如，一个红光色阻单元的区域设置一个主间隔物13，与该红光色阻单元相邻的一个绿光色阻单元的区域设置一个辅间隔物14。
在第二个实施例中，同样地，主间隔物13和辅间隔物14分设于不同色阻单元2221对应的区域。任意一个色阻单元2221至多设置一个主间隔物13或者一个辅间隔物14。可选地，参考图1和图8，一个主间隔物13设置于一个色阻单元对应的区域，一个辅间隔物14设置于相隔的另一个色阻单元对应的区域。例如，一个红光色阻单元的区域设置一个主间隔物13，一个蓝绿光色阻单元的区域设置一个辅间隔物14，该红光色阻单元和蓝光色阻单元之间有一绿光色阻单元。
在第一、第二实施例中，全部主间隔物13可以一对一地设置于第一颜色的色阻单元对应的区域，全部辅间隔物14可以一对一地设置于第二颜色的色阻单元对应的区域，第一颜色和第二颜色不同。例如，全部的主间隔物13均设置于红光色阻单元、绿光色阻单元或者蓝光色阻单元对应的区域对应的区域，全部的辅间隔物14均设置于与其相异的红光色阻单元、绿光色阻单元或 者蓝光色阻单元对应的区域。这样便于制程控制。
在第三个实施例中，参考图2和图7，一个主间隔物13和一个辅间隔物14构成一间隔物组，一个间隔物组设置于一个色阻单元对应的区域。例如，一个红光色阻单元的区域设置一个主间隔物13和一个辅间隔物14。当然，还可以在一个绿光色阻单元或者一个蓝光色阻单元的区域设置一个主间隔物13和一个辅间隔物14。为了更加便于制作，可以将每组间隔物组设置于相同颜色的色阻单元上，便于制程控制。
在一个实施例中，主间隔物13和辅间隔物14各为多个且均匀分布。可选地，主间隔物13和辅间隔物14的形状可选为圆台形结构，其靠近第一基层11的一端直径较大，靠近第二基层21的一端直径较小，便于制备且结构强度和稳定性较好。在其他实施例中，主间隔物13和辅间隔物14也可以是直径一致的圆柱形。在其他实施例中，主间隔物13和辅间隔物14也可以是棱台形或者棱柱形等等。
参考图9，本实用新型实施例提供的显示面板100主要用于液晶显示器，包含该显示面板100的显示装置200也在本实用新型的保护范围内。该显示装置200还包括背光模组，用于提供照明，该背光模组可以是侧入式背光模组，也可以是直下式背光模组。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
