现结合具体实施例对本申请的技术方案进行描述。
本申请提供一种显示面板1，如图1-图6所示，包括第一基板10、与所述第一基板10相对设置的第二基板20、及位于所述第一基板10与所述第二基板20之间的液晶层30；
所述第一基板10包括衬底11、位于所述衬底11上的阵列结构层12、位于所述阵列结构层12上的色阻层13、及位于所述色阻层13上的像素电极层（图中未出示）和柱状隔垫层14；
所述柱状隔垫层14包括至少一隔垫柱141，所述色阻层13包括至少一支撑所述隔垫柱141的支撑色阻块131，任一所述支撑色阻块131一侧设置有支撑补偿块1311，所述支撑补偿块1311位于所述阵列结构层12上，所述隔垫柱141设置于所述支撑色阻块131上和所述支撑补偿块1311上。
可以理解的是，目前，在高刷新率和高分辨率的显示面板中，随着显示面板1分辨率的提高，使得显示面板的像素尺寸减小，对应色阻的尺寸也相应减小，导致在诸如COA型显示面板的结构中，色阻的横向尺寸（宽度）无法满足对柱状隔垫物的支撑需求；具体在现有的结构中，不仅使得柱状隔垫物的底部外露于色阻外，导致在后期的信赖性测试中，容易造成柱状隔垫物的脱落；也使得柱状隔垫物不能良好提供对所述显示面板中上下两侧基板的支撑力，进而影响显示面板内的面压，本申请通过在支撑色阻块131一侧设置支撑补偿块1311，并将设置于所述支撑色阻块131上的隔垫柱141延伸至所述支撑补偿块1311上，增大了对隔垫柱141站位的支撑面积，为隔垫柱141提供了很好的支撑保障，同时，也稳固了隔垫柱141的支撑性能，改善了显示面板1中的面压效果。
承上，如图2所示，显然，所述第一基板10为COA型基板，所述衬底11可以为刚性衬底或柔性衬底中的一种。当所述衬底11为刚性衬底时，所述衬底的材料可以为玻璃、石英等材料制备。当所述衬底为柔性衬底时，所述衬底可以为聚酰亚胺等材料。而在LCD显示面板中，衬底11结构一般均设置为刚性衬底，此处不对其作详细介绍。
所述阵列结构层12包括多个薄膜晶体管。所述薄膜晶体管可以为蚀刻阻挡型、背沟道蚀刻型或顶栅薄膜晶体管型等结构，具体没有限制。例如顶栅薄膜晶体管型的所述薄膜晶体管可以包括位于所述衬底11上的有源层121、位于所述有源层121上栅绝缘层122、位于所述栅绝缘层122上的栅极层123、位于所述栅极层123上的层间绝缘层124、位于所述层间绝缘层123上的源漏极层125、位于所述源漏极层125上的钝化层126。
值得注意的是，如图1和图3所示，所述色阻层13包括多个呈阵列布置的色阻块，所述色阻块为起到支撑所述隔垫柱141作用的所述支撑色阻块131或为不起支撑所述隔垫柱141作用的常规色阻块132，并且，可以理解的是，所述支撑色阻块131的数量与所述隔垫柱141的数量相等且一一对应，每一所述支撑色阻块131上均设有一所述隔垫柱141；具体的，在实际的应用中，根据产品的实际需求，各所述色阻层13中可以是全部所述色阻块均为所述支撑色阻块131，也可以是部分所述色阻块为所述支撑色阻块131，具体在所述所述支撑色阻块131的数量大于等于2时，如图1所示，任一两所述支撑色阻块131之间的排布方式可以是呈间隔排布，即该两所述支撑色阻块131之间至少间隔有一所述常规色阻块132，也可以是如图2所示，两所述支撑色阻块131呈相邻排布，具体的排布形式在此不做限制；显然，如图1和图3所示，位于一所述支撑色阻块131两侧的两所述色阻块既可以是两所述支撑色阻块131，也可以是一所述支撑色阻块131与一所述常规色阻块132，在本实施例中，所述支撑色阻块131与位于该所述支撑色阻块131两侧的所述色阻块相邻，以便于最大化的增加所述支撑色阻块131的面积，为所述隔垫柱141提供更大的站位支撑面积，也使得所述显示面板1的结构更为稳定。
在一实施例中，如图1-图4所示，任一所述支撑色阻块131内的一侧边处开设有一第一开口1312，所述支撑补偿块1311设置于所述支撑色阻块131远离所述第一开口1312的一侧边处；所述隔垫柱141远离所述支撑补偿块1311的一侧延伸至所述第一开口1312处，且所述隔垫柱141在垂直于所述色阻层13方向上的正投影与所述第一开口1312至少部分重合。显然，在COA型显示面板1的结构中，由于色阻层13具备一定的厚度，在形成使像素电极层与阵列结构层12之间电连接的第一过孔之前，需要在所述支撑色阻块131内形成第一开口1312；可以理解的是，通过将所述隔垫柱141远离所述支撑补偿块1311的一侧延伸至所述第一开口1312处，且所述隔垫柱141在垂直于所述色阻层13方向上的正投影与所述第一开口1312至少部分重合，使得所述隔垫柱141部分延伸至所述第一开口1312的上方，进一步增大了所述隔垫柱141的截面积，有利于提高所述隔垫柱141对所述显示面板1整体的支撑效果。
承上，本实施例中，如图2所示，将所述隔垫柱141的站位设于所述支撑补偿块1311与所述第一开口1312之间，并且使所述隔垫柱141两侧分别延伸至所述支撑补偿块1311上和所述第一开口1312上，同时，将所述第一开口1312的位置设置于所述支撑色阻块131内远离所述支撑补偿块1311的一侧，最大化增加了所述第一开口1312与所述支撑补偿块1311之间的距离，也即是最大化的提高了所述支撑色阻块131的横向距离，此外，所述第一开口1312和所述支撑补偿块1311所对应的区域并不影响所述第一基板10的透光区，从而达到在保证不影响所述显示面板1开口率的基础上，最大化的增加了所述隔垫柱141的横截面积和所述支撑色阻块131对所述隔垫柱141的支撑面积，降低了所述隔垫柱141在后期的信赖性测试中脱落的风险，提高了所述显示面板1的良品率。
在一实施例中，如图2所示，所述第一开口1312内设置有使所述像素电极层与所述阵列结构层12电连接的第一过孔127，所述隔垫柱141在垂直于所述色阻层13方向上的正投影与所述第一过孔127在垂直于所述色阻层13方向上的正投影相邻接。可以理解的是，所述显示面板1还包括贯穿所述色阻层13及所述钝化层126的第一过孔127，所述像素电极层通过所述第一过孔127与所述阵列结构层12的源/漏极电连接，而在COA型显示面板的制作工艺中，在完成所述第一基板10后，还需采用诸如聚酰亚胺的材料在所述第一基板10上进行配向，为避免所述隔垫柱141远离所述支撑补偿块1311的一侧延伸至所述第一开口1312上方的面积过大，以至于所述隔垫柱141在垂直于所述色阻层13的方向上遮住所述第一过孔127，影响所述第一过孔127和所述第一开口1312在后续配向过程中对聚酰亚胺的引流效果，显然，所述隔垫柱141在垂直于所述色阻层13方向上的正投影与所述第一过孔127在垂直于所述色阻层13方向上的正投影不能有重合的部分，也即是所述隔垫柱141在垂直于所述色阻层13方向上的正投影与所述第一过孔127在垂直于所述色阻层13方向上的正投影之间的距离大于等于0，本实施例中，采用所述隔垫柱141在垂直于所述色阻层13方向上的正投影与所述第一过孔127在垂直于所述色阻层13方向上的正投影相邻接的方式，也即是所述隔垫柱141远离所述支撑补偿块1311的一侧延伸至所述第一开口1312中的第一过孔127边缘处，此时，所述隔垫柱141在垂直于所述色阻层13方向上的正投影与所述第一过孔127在垂直于所述色阻层13方向上的正投影之间的距离等于0，在保证后续配向效果的基础上，最大化的实现对所述隔垫柱141横截面的增加。
在一实施例中，所述第一开口1312底部靠近所述隔垫柱141的一侧边缘至少设有一第一凹槽1313，所述第一凹槽1313与所述第一开口1312具有重叠区，可以理解的是，在COA型显示面板1的制作工艺中，在完成所述色阻层13的制作，并在所述支撑色阻块131上形成第一开口1312后，会在所述支撑色阻块131上制作所述隔垫柱141，但是，由于隔垫材料的流动性，导致隔垫材料流入所述第一开口1312，会使得所述第一过孔127与所述第一开口1312边界的间距过小，甚至会影响到所述第一过孔127；尤其是在前述显示面板1的结构中，为最大化的增加所述隔垫柱141横截面，提高所述隔垫柱141对所述显示面板1整体的支撑效果，将所述隔垫柱141远离所述支撑补偿块1311的一侧延伸至所述第一开口1312处，且使所述隔垫柱141在垂直于所述色阻层13方向上的正投影与所述第一开口1312至少部分重合，由于增加了所述隔垫柱141的尺寸，在制作所述隔垫柱141时会有更多的隔垫材料流入所述第一开口1312，影响所述第一开口1312和所述第一过孔127的整体结构和尺寸设计，因此，如图2所示，所述色阻层13还包括在所述第一开口1312底部靠近所述隔垫柱141的一侧边缘至少设置的一第一凹槽1313，以便于流入所述第一开口1312内的隔垫材料进一步流入所述第一凹槽1313内，保证所述第一开口1312和所述第一过孔127的整体结构和尺寸设计不受影响，并且，再具体应用中，在能达到容置流入第一开口1312内的隔垫材料的基础上，所述第一凹槽1313的数量在此不做限制。
承上，在本实施例中，所述第一凹槽1313与所述第一开口1312具有重叠区，如图5所示，可以是所述第一凹槽1313在所述第一开口1312上的正投影位于所述第一开口1312区，如图6所示，也可以是所述第一凹槽1313在所述第一开口1312上的正投影位于所述第一开口1312和与所述第一开口1312相邻的色阻区内，由于所述第一开口1312的边缘区域与所述支撑色阻块131具有一定的高度差，在制作所述隔垫柱141时由于隔垫材料的流动性导致隔垫材料流入所述第一开口1312内。所述第一凹槽1313的设置使得流入所述第一开口1312内的色阻材料流入所述第一凹槽1313内，使得所述第一开口1312的底面平整，保证了所述第一过孔127与所述第一开口1312边界的间距，也避免了对所述第一过孔127在诸如后续配向时造成影响；具体的，所第一凹槽1313的底部可以是倾斜设置，比如，所述第一凹槽1313的底部远离所述支撑补偿块1311的一侧高于所述靠近所述支撑补偿块1311的一侧，或者呈其它具有高度差的渐进形式，使得在所述隔垫材料由于高度差流入所述第一凹槽1313内后，通过所述第一凹槽1313的底部呈倾斜的方式达到引流的效果。
在一实施例中，如图4所示，所述隔垫柱141在所述第一开口1312处的宽度L1大于所述第一开口1312的宽度L2；所述隔垫柱141在所述第一开口1312处的宽度方向垂直于所述支撑补偿块1311与所述第一开口1312之间的连线，本实施例中，在前述将所述隔垫柱141两侧分别延伸至所述支撑补偿块1311上和所述第一开口1312上，达到增加所述隔垫柱141的长度之后，通过使所述隔垫柱141在所述第一开口1312处的宽度大于所述第一开口1312的宽度，增加所述隔垫柱141在所述第一开口1312处的宽度，在具体应用中，所述隔垫柱141在所述第一开口1312处的宽度既可以大于所述第一开口1312的宽度，也可以小于所述第一开口1312的宽度，本实施例中，通过设置隔垫柱141在所述第一开口1312处的宽度大于所述第一开口1312的宽度，使得所述隔垫柱141在所述第一开口1312的三条侧边处均得到所述支撑色阻块131的支撑，具备较好的稳定性，可以理解的是，所述隔垫柱141在所述第一开口1312处的宽度仅限于在所述隔垫柱141中处于所述第一开口1312位置的宽度，当然，所述隔垫柱141中远离所述第一开口1312的部分，其具体的宽度值可以根据实际需要进行设定，在此不做限定。
在一实施例中，所述支撑补偿块1311在横向截面上的形状包括梯形、矩形或半圆形中的一种；所述横向截面与所述色阻层13所对应的平面平行；可以理解的是，所述支撑补偿块1311在横向截面上的形状可以根据实际需要进行选择，具体的，在所述支撑补偿块1311在横向截面上呈一固定形状后，可以选择该固定形状的最长边为靠近所述支撑补偿块1311的一侧，以最大化保证所述支撑补偿块1311与所述支撑色阻块131的接触面积，同时，所述支撑补偿块1311的高度与所述支撑色阻块131的高度相同，便于提高所述隔垫柱141由所述支撑色阻块131上延伸至所述支撑补偿块1311之后整体站位的稳定性，也便于后续所述隔垫柱141的制作。
在一实施例中，所述支撑补偿块1311的材料与所述支撑色阻块131的材料相同，且为一体成型结构；显然，所述支撑补偿块1311的材料可以选用与所述支撑色阻块131的相同的色阻材料，并且，可以采用同一制程一体成型，使得所述支撑补偿块1311与所述支撑色阻块131具备较好的整体性，结构更加稳固，此外，也并不影响现有显示面板1整体的制作工艺流程，区别仅在于改变了色阻层13制作过程中的光罩形状，使得本申请在实际生产中具备较好的应用性。
在一实施例中，如图1和图3所示，所述隔垫柱141在垂直于所述色阻层13方向上的正投影覆盖所述支撑补偿块1311在垂直于所述色阻层13方向上的正投影；也即是所述隔垫柱141中位于所述支撑补偿块1311的部分完全布满所述支撑补偿块1311的表面，充分利用所述支撑补偿块1311的面积，同样，此种结构方式，也并不影响现有显示面板1整体的制作工艺流程，区别仅在于改变了柱状隔垫层14制作过程中的光罩形状，实用性较强，便于推广。
在一实施例中，如图7所示，当位于一所述支撑色阻块131两侧的两所述色阻块分别为所述支撑色阻块131何所述常规色阻块132时，所述隔垫柱141位于所述支撑色阻块131上的部分可进一步延伸至所述常规色阻块132上，本实施例中，所述常规色阻块132内开设有一第二开口1321，所述第二开口1321与所述支撑色阻块131相邻设置，所述隔垫柱141位于所述支撑色阻块131上的部分进一步延伸至所述第二开口1321的上方，且所述隔垫柱141在垂直于所述色阻层13方向上的正投影与所述第二开口1321至少部分重合，具体的，所述第二开口1321内设置有使所述像素电极层与所述阵列结构层12电连接的第二过孔128，所述隔垫柱141经过所述支撑色阻块131延伸至所述第二过孔128处，也即是所述隔垫柱141在垂直于所述色阻层13方向上的正投影与所述第二过孔128在垂直于所述色阻层13方向上的正投影相邻接或者相切，从而进一步增大所述隔垫柱141的截面积，有利于提高所述隔垫柱141对所述显示面板1整体的支撑效果。此外，如图8所示，当位于一所述支撑色阻块131两侧的两所述色阻块分均为所述支撑色阻块131时，所述隔垫柱141位于其中一所述支撑色阻块131上的部分也可进一步延伸至另一所述支撑色阻块131上，具体结构在此不再赘述。
承上，如图9所示，本实施例中，所述隔垫柱141位于所述支撑色阻块131上的部分进一步延伸至所述第二开口1321的上方，所述第二开口1321底部靠近所述支撑色阻块131的一侧开设有至少一第二凹槽1322，所述第二凹槽1322与所述第二开口1321具有重叠区，所述第二凹槽1322用于对在制作所述隔垫柱141时的隔垫材料进行引流，具体的，在制作所述隔垫柱141时由于隔垫材料的流动性导致隔垫材料流入所述第二开口1321内。所述第二凹槽1322的设置使得流入所述第二开口1321内的色阻材料流入所述第二凹槽1322内，使得所述第二开口1321的底面平整，保证了所述第二过孔128与所述第二开口1321边界的间距，也避免了对所述第二过孔128在诸如后续配向时造成影响。
本申请还提供一种显示装置，如图10所示，所述显示装置包括背光模组2、及位于所述背光模组上如前任一项所述的显示面板1本实施例中的所述显示装置的工作原理与上述显示面板1的工作原理相同或相似，此处不再赘述。
综上所述，本申请包括第一基板10、与所述第一基板10相对设置的第二基板20、及位于所述第一基板10与所述第二基板20之间的液晶层30；所述第一基板10包括衬底11、位于所述衬底11上的阵列结构层12、位于所述阵列结构层12上的色阻层13、及位于所述色阻层13上的像素电极层和柱状隔垫层14；所述柱状隔垫层14包括至少一隔垫柱141，所述色阻层13包括至少一支撑所述隔垫柱141的支撑色阻块131，任一所述支撑色阻块131一侧设置有支撑补偿块1311，所述支撑补偿块1311位于所述阵列结构层12上，所述隔垫柱141设置于所述支撑色阻块131上和所述支撑补偿块1311上；通过在用于支撑隔垫柱141的支撑色阻块131一侧设置支撑补偿块1311，并将设置于所述支撑色阻块131上的隔垫柱141延伸至所述支撑补偿块1311上，增大了对隔垫柱141站位的支撑面积，为隔垫柱141提供了很好的支撑保障，同时，也稳固了隔垫柱141的支撑性能，改善了显示面板1中的面压效果。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
