如图1所示的传统的LCD显示装置1’中，阵列（Array）基板2’做得比上层的CF基板3’稍大一些形成台阶区4’，在位于台阶区4’的阵列基板2’的正面（靠近CF基板的一侧）设置绑定衬垫，用于与驱动线路5’绑定连接；台阶区4’上还覆盖有密封胶7’，密封胶7’用于连接框体6’和阵列基板2’且用于遮挡台阶区4’。然而，密封胶7’将导致面板的边框过宽，不利于实现窄边框化显示；并且，驱动线路5’在台阶区4’与绑定衬垫绑定后其余部分从阵列基板2’的侧面弯折至阵列基板2’的背部，该设计将导致驱动线路5’与安装在面板侧面的框体6’产生挤压风险；另外当如图1所示的LCD显示装置应用于拼接屏显示领域时，将导致拼接缝过大，影响画质。
为了解决上述技术问题，本申请提出了一种显示面板、显示装置以及拼接显示装置，具体参考以下几个实施例的描述。
如图2和图3所示，本申请实施例提供了一种显示面板1，显示面板1包括第一基板2、与第一基板2相对设置的第二基板3、夹设于第一基板2和第二基板3之间的液晶层4、以及与第二基板3绑定连接的柔性电路板5。第一基板2包括至少与液晶层4对应设置的公共电极层6；第二基板3具有第一区域7和位于第一区域7一侧的第二区域8，且包括位于第一区域7和第二区域8的阵列（Array）层9以及位于阵列层9远离液晶层4一侧的彩色滤光（CF）层10；第一基板2对应第一区域7设置。柔性电路板5与位于第二区域8的阵列层9绑定连接，且柔性电路板5位于阵列层9靠近液晶层4的一侧。
可以理解的，将公共电极层6和阵列层9分别设置在液晶层4的两侧，用于产生使液晶偏转的电场，以实现显示功能。
具体的，如图3所示，第一基板2还包括衬底11，例如玻璃衬底11；公共电极层6位于衬底11上，且公共电极层6位于衬底11靠近液晶层4的一侧。
具体的，阵列层9包括位于第一区域7且呈阵列分布的多个像素驱动电路单元（未示出）以及位于第二区域8且与多个像素驱动电路单元电连接的衬垫组；衬垫组裸露于阵列层9靠近液晶层4的一侧，且与柔性电路板5绑定连接。
可以理解的，每个像素驱动电路单元包括至少一个薄膜晶体管。
在一具体实施方式中，如图2所示，阵列层9和彩色滤光层10的边缘对齐设置，且彩色滤光层10远离阵列层9的一侧为显示面。
具体的，彩色滤光层10包括位于第一区域7且呈阵列排布的多个色阻单元12以及位于第一区域7和第二区域8且位于任意相邻的两个色阻单元12之间的遮光层13。可以理解的，彩色滤光层10中的遮光层13可以对第二区域8中的柔性电路板5以及其他走线起到遮挡作用，故不需要在彩色滤光层10上增加用于遮挡第二区域的前框、黑胶带或密封胶。
在一具体实施方式中，每个色阻单元12包括红色色阻（R）、绿色色阻（G）和蓝色色阻（B）中的任意一个；例如每三个相邻的色阻单元12构成一个像素单元，每个像素单元包括红色色阻（R）、绿色色阻（G）和蓝色色阻（B）。
在一具体实施方式中，遮光层13包括黑色矩阵（BM），但不限于此。
具体的，如图2所示，第二基板3还包括位于阵列层9和彩色滤光层10之间的透明衬底14以及位于彩色滤光层10远离透明衬底14一侧的保护层15。可以理解的，阵列层9和彩色滤光层10分别直接形成在透明衬底14的相对的两个表面上，例如在第一表面20形成阵列层9且在第二表面21形成彩色滤光层10。
具体的，透明衬底14的材料包括玻璃，但不限于此。
具体的，第一基板2和第二基板3之间还设有胶框16，用于将液晶层4封装在第一基板2和第二基板3之间。
具体的，柔性电路板5包括覆晶薄膜(Chip On Film，COF)，但不限于此。
在一具体实施方式中，柔性电路板5远离阵列层9的一侧还绑定有驱动电路板17，例如印刷电路板（PCB）。
在一具体实施方式中，如图4所示，柔性电路板5远离阵列层9的部分可以向背离阵列层9的方向弯折设置。
本申请实施例中，将阵列层9和彩色滤光层10设置在液晶层4的同一侧，且柔性电路板5绑定在阵列层9靠近液晶层4的一侧，避免了将绑定位置暴露在显示面板1的显示面和侧面，从而避免了在显示面板1的显示面设置用于遮挡位于绑定位置（第二区域8）的柔性电路板5的遮挡结构，可以在视觉上缩窄显示面板1的边框，实现窄边框显示。
如图5所示，本申请实施例还提供一种显示面板30，与前述实施例不同的在于透明衬底的结构。具体的，本申请实施例中，透明衬底由叠加设置的第一透明衬底18和第二透明衬底19构成；第一透明衬底18位于阵列层9和第二透明衬底19之间，第二透明衬底19位于第一透明衬底18和彩色滤光层10之间。
具体的，第一透明衬底18和第二透明衬底19的材料包括玻璃，但不限于此；阵列层9直接形成在第一透明衬底18上，且彩色滤光层10直接形成在第二透明衬底19上；将第一透明衬底18远离阵列层9的一侧和第二透明衬底19远离彩色滤光层10的一侧对位贴合（例如真空贴合）后形成了第二基板3。
可以理解的，第一基板2和第二基板3对盒设置时，阵列层9靠近第一基板2设置。
本申请实施例中，将阵列层9和彩色滤光层10设置在液晶层4的同一侧，且柔性电路板5绑定在阵列层9靠近液晶层4的一侧，避免了将绑定位置暴露在显示面板1的显示面和侧面，从而避免了在显示面板1的显示面设置用于遮挡位于绑定位置（第二区域8）的柔性电路板5的遮挡结构，可以在视觉上有效的缩窄显示面板1的边框，实现窄边框显示。
如图6所示，本申请实施例还提供一种显示面板40，与前述实施例不同的在于透明衬底的设置位置。具体的，本申请实施例中，透明衬底14’位于彩色滤光层远离阵列层9一侧。
具体的，透明衬底14’的材料包括玻璃，但不限于此。
具体的，彩色滤光层和阵列层9依次叠加形成在透明衬底14’上；第一基板2和第二基板3对盒设置时，将透明衬底14’倒置，使得阵列层9靠近第一基板2设置。
本申请实施例中，将阵列层9和彩色滤光层10设置在液晶层4的同一侧，且柔性电路板5绑定在阵列层9靠近液晶层4的一侧，避免了将绑定位置暴露在显示面板1的显示面和侧面，从而避免了在显示面板1的显示面设置用于遮挡位于绑定位置（第二区域8）的柔性电路板5的遮挡结构，可以在视觉上缩窄显示面板1的边框，实现窄边框显示。
如图7所示，本申请实施例还提供了一种显示装置22，显示装置22包括前面任意一个实施例所述的显示面板1（或30，40）、背光模组23、以及框体24。背光模组23位于第一基板2远离第二基板3的一侧；柔性电路板5远离阵列层9的部分弯折至与背光模组23固定连接；框体24位于显示面板1和背光模组23的侧面，且与对应的显示面板1（或30，40）和背光模组23固定连接。当然，框体24还可以位于背光模组23的底部，此处不做限制。
具体的，显示装置22还包括至少设置在显示面板1（或30，40）与框体24之间的密封胶25。具体的，密封胶25沿显示面板1（或30，40）的边缘设置；可以理解的，密封胶25部分覆盖第二区域8。
与图1所示的传统的LCD显示装置1’中的密封胶7’相比，本申请实施例中位于第二区域8的密封胶25的宽度较小，对实现窄边框的影响较小。
本申请实施例中，将阵列层9和彩色滤光层10设置在液晶层4的同一侧，且柔性电路板5绑定在阵列层9靠近液晶层4的一侧，避免了将绑定位置暴露在显示面板1（或30，40）的显示面和侧面；一方面，可以避免将柔性电路板5弯折至显示面板1（或30，40）的侧面，从而避免柔性电路板5与框体24之间产生挤压风险，从而提高显示装置22的良率和稳定性；另一方面，可以避免在显示面板1（或30，40）的显示面设置用于遮挡位于绑定位置的柔性电路板5的遮挡结构（例如前框、黑胶带或密封胶），从而有效的缩窄显示装置22的边框，以实现窄边框显示。
如图7和图8所示，本申请实施例还提供了一种拼接显示装置26，拼接显示装置26包括多个相互拼接设置的拼接单体27；具体的，拼接单体27的结构与前述实施例中的显示装置22的结构相同，可以参考图7所示的结构。
可以理解的，每个拼接单体27包括前述实施例所述的显示面板1（或30，40），以及与显示面板1（或30，40）对应设置的背光模组23和框体24。
具体的，背光模组23位于对应的第一基板2远离第二基板3的一侧；柔性电路板5远离阵列层9的部分弯折至与对应的背光模组23固定连接；框体24位于对应的显示面板1和背光模组23的侧面，且与对应的显示面板1（或30，40）和背光模组23的侧面固定连接。
具体的，拼接单体27还包括至少设置在显示面板1（或30，40）与框体24之间的密封胶25。具体的，密封胶25沿显示面板1（或30，40）的边缘设置；可以理解的，密封胶25部分覆盖第二区域8。
与图1所示的传统的LCD显示装置1’中的密封胶7’相比，本申请实施例中位于第二区域8的密封胶25的宽度较小，对实现窄边框的影响较小，且可以减小相邻的两个拼接单体27之间的拼接缝。
当然，在其他实施方式中，任意相邻的两个拼接单体27之间的框体24可以取消掉，直接将显示面板1（或30，40）的侧面拼接，进一步减小拼接缝。
本申请实施例中，将阵列层9和彩色滤光层10设置在液晶层4的同一侧，且柔性电路板5绑定在阵列层9靠近液晶层4的一侧，避免了将绑定位置暴露在显示面板1（或30，40）的显示面和侧面；一方面，可以避免将柔性电路板5弯折至显示面板1（或30，40）的侧面，从而避免柔性电路板5与框体24之间产生挤压风险，从而提高拼接单体27的良率和稳定性；另一方面，可以避免在显示面板1（或30，40）的显示面设置用于遮挡位于绑定位置的柔性电路板5的遮挡结构（例如前框、黑胶带或密封胶），从而有效的缩窄拼接单体27的边框，进而有效的减小拼接缝，以提高显示效果。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上对本申请实施例所提供的一种显示面板、显示装置以及拼接显示装置进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
