具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
薄膜晶体管液晶显示器(英文：Thin Film Transistor Liquid Crystal Display；简称：TFT-LCD)包括液晶显示面板，液晶显示面板包括对盒成形的阵列基板和对置基板，以及位于阵列基板与对置基板之间的液晶和封框胶，封框胶配置为粘合阵列基板与对置基板以避免液晶泄漏。液晶显示面板是通过对液晶母板进行切割形成的显示面板，液晶母板由阵列母板和对置母板对 盒形成。
实际应用中，为了对液晶母板进行搬运，阵列母板的周边区域的液晶区域与阵列母板的边缘之间的距离较大，当不同液晶区域的外围区域涂覆的封框胶中设置的硅球的尺寸相同时，在将对置母板与阵列母板对盒的过程中，受阵列母板的周边区域的留白区域(留白区域指的是阵列母板的周边区域的液晶区域与阵列母板的边缘04之间的区域)的影响，阵列母板的周边区域承受的对盒力(对盒力指的是硅球施加在阵列母板上的压力)小于阵列母板的中央区域承受的对盒力，从而导致阵列母板受力不均，进一步导致最终切割形成的多个液晶显示面板中，从液晶母板的周边区域切割下来的液晶显示面板的显示效果与从液晶母板的中央区域切割下来的液晶显示面板的显示效果的差异较大。
如图1所示，阵列母板01包括多个液晶区域011，在液晶显示面板的制造过程中，首先在每个液晶区域011的外围区域涂覆封框胶02，该封框胶02中设置有硅球，且不同液晶区域011的外围区域涂覆的封框胶02中设置的硅球的尺寸相同，然后在每个液晶区域011滴注液晶03，使液晶03位于封框胶02围成的空间内，之后将对置母板与阵列母板011对盒，并对封框胶02进行固化，使对置母板与阵列母板011通过封框胶02粘合形成液晶母板，最后对液晶母板进行切割形成多个液晶显示面板，多个液晶显示面板中的每个液晶显示面板可以如图2所示。图3示出了图2所示的液晶显示面板的立体结构示意图，参见图3，封框胶02中设置有硅球021，且该液晶显示面板的不同外围区域的封框胶02中设置的硅球021的尺寸相同，该硅球021可以对阵列基板012(包括阵列母板01的液晶区域011和液晶区域011的外围区域)和对置基板(图3中未示出)进行支撑，维持液晶显示面板的盒厚。
实际生产过程中，为了对液晶母板进行搬运，如图1所示，阵列母板01的周边区域的液晶区域011与阵列母板01的边缘04之间的距离较大，从而阵列母板01的周边区域的留白区域(如图1所示的区域013)的面积较大，在将对置母板与阵列母板01对盒的过程中，由于不同液晶区域011的外围区域涂覆的封框胶02中设置的硅球021的尺寸相同，阵列母板01的周边区域承受的对盒力小于阵列母板01的中央区域承受的对盒力，从液晶母板的周边区域切割下来的液晶显示面板的对盒效果与从液晶母板的中央区域切割下来的液晶显示面板的对盒效果不同，会切割出来的液晶显示面板的液晶盒厚不 同，导致显示效果差异较大。例如，从液晶母板的周边区域切割下来的液晶显示面板的显示颜色与从液晶母板的中央区域切割下来的液晶显示面板的显示颜色存在差异，当这种差异超出了允许范围时，导致显示面板报废。
根据本公开实施例的显示面板及其制造方法，通过特殊的坐标设计，交叉涂覆不同的封框胶，不同的封框胶中设置有不同尺寸硅球，使从液晶母板的周边区域切割下来的液晶显示面板的一条边或者两条边的盒厚与其他边的盒厚不同，确保从液晶母板的周边区域切割下来的液晶显示面板的显示颜色与从液晶母板的中央区域切割下来的液晶显示面板的显示颜色一致，减小从液晶母板的周边区域切割下来的液晶显示面板的显示效果与从液晶母板的中央区域切割下来的液晶显示面板的显示效果的差异。在下文中通过实施例中本公开进行描述。
图4其示出了根据本公开的一个实施例的显示面板的制造方法的流程图，所述液晶母板包括第一母板和第二母板，以及设置在第一母板上的多个呈矩阵方式排列的液晶区域，所述第一母板包括相互垂直的第一边缘和第二边缘，所述多个液晶区域包括与所述第一母板的第一边缘相邻的第一液晶区域和均不与所述第一母板的第一边缘和第二边缘相邻的中央液晶区域，该方法包括：
步骤401、在第一母板的多个液晶区域的每一个的外围区域涂覆封框胶，其中，在中央液晶区域的外围区域涂覆设置有第一支撑结构的第一封框胶，在第一液晶区域的外围区域涂覆设置有第二支撑结构的第二封框胶，其中，所述第二支撑结构的高度大于第一支撑结构的高度。
步骤402、将第二母板和第一母板对盒，并在每个液晶区域中设置液晶，形成液晶母板。
综上所述，在根据本公开实施例的显示面板的制造方法中，由于中央液晶区域不与第一母板的边缘相邻，第一液晶区域与第一母板的边缘相邻，且涂覆在第一液晶区域的外围区域的第二封框胶中的支撑结构的高度大于涂覆在中央液晶区域的外围区域的第一封框胶中的支撑结构的高度，这样一来，在将第二母板与第一母板对盒的过程中，位于第一液晶区域的外围区域的封框胶中设置的支撑结构向第一母板施加的对盒力与位于中央液晶区域的外围区域的封框胶中设置的支撑结构向第一母板施加的对盒力可以趋于相等，第一母板受力趋于均匀，消除了从液晶母板的周边区域切割下来的显示面板的 显示效果与从液晶母板的中央区域切割下来的显示面板的显示效果之间的差异，有助于使从液晶母板上切割下来的不同显示面板的显示效果一致。
在本公开的一个实施例中，多个液晶区域还包括与所述第一母板的第二边缘相邻的的第二液晶区域，第一液晶区域与第一母板的第一边缘之间的距离为第一距离，第二液晶区域与第一母板的第二边缘之间的距离为第二距离，步骤401还包括：
当第二距离小于第一距离时，在第二液晶区域的外围区域涂覆第一封框胶；
当第二距离大于或等于第一距离时，在第二液晶区域的外围区域涂覆第二封框胶。
在本公开的一个实施例中，所述每个第一液晶区域的外围区域包括邻近所述第一母板的第一边缘的第一外围子区域和不邻近所述第一母板的第一边缘的第二外围子区域，在每个第一液晶区域的外围区域涂覆第二封框胶，包括：在所述第一外围子区域涂覆所述第二封框胶；在所述第二外围子区域中涂覆所述第一封框胶。
在本公开的一个实施例中，涂覆在所述第一液晶区域的第一外围子区域的第二封框胶和涂覆在所述第一液晶区域的第二外围子区域的第一封框胶形成封闭结构。
在本公开的一个实施例中，涂覆在所有第一液晶区域的第一外围子区域中的第二封框胶一体形成。
在本公开的一个实施例中，第一支撑结构和第二支撑结构均呈球体，所述第一支撑结构和所述第二支撑结构的高度为各自的直径。
在本公开的一个实施例中，所述第一支撑结构或所述第二支撑结构为硅球、塑料球和玻璃纤维球中的至少一种。
在本公开的一个实施例中，第一支撑结构的高度的取值范围为3.6微米～4.4微米；以及第二支撑结构的高度的取值范围包括：3.8微米～4.6微米。
在本公开的一个实施例中，在步骤402之后，该方法还包括：
沿液晶母板的切割线对液晶母板进行切割，得到多个显示面板，切割线在第一母板上的正投影位于每两个相邻的液晶区域之间。
在本公开的一个实施例中，步骤402包括：
将第二母板与第一母板对盒，在每个液晶区域内设置有液晶；
对封框胶进行固化，得到液晶母板。
在本公开的一个实施例中，第一母板为阵列母板，第二母板为对置母板；或者，
第一母板为对置母板，第二母板为阵列母板。
上述所有可选技术方案，可以以任意方式结合以形成本公开的可行实施例，在此不再一一赘述。
综上所述，在根据本公开实施例的显示面板的制造方法中，由于中央液晶区域位于第一母板的中央区域，第一液晶区域位于第一母板的第一周边区域，且涂覆在第一液晶区域的外围区域的第二封框胶中设置的第二支撑结构的高度大于涂覆在中央液晶区域的外围区域的第一封框胶中设置的第一支撑结构的高度，这样一来，在将第二母板与第一母板对盒的过程中，位于第一液晶区域的外围区域的第二封框胶中设置的第二支撑结构向第一母板施加的对盒力与位于中央液晶区域的外围区域的第一封框胶中设置的第一支撑结构向第一母板施加的对盒力趋于相等，第一母板受力趋于均匀，消除了从液晶母板的周边区域切割下来的显示面板的显示效果与从液晶母板的中央区域切割下来的显示面板的显示效果之间的差异，有助于使从液晶母板上切割下来的不同显示面板的显示效果一致。
请参考图5，其示出了根据本公开另一个实施例的显示面板的制造方法的方法流程图，所述液晶母板包括第一母板和第二母板，以及设置在第一母板上的多个呈矩阵方式排列的液晶区域，所述第一母板包括相互垂直的第一边缘和第二边缘，所述多个液晶区域包括与所述第一母板的第一边缘相邻的第一液晶区域和均不与所述第一母板的第一边缘和第二边缘相邻的中央液晶区域，参见图5，该方法包括：

在本公开实施例中，第一液晶区域的外围区域包括邻近第一母板的第一边缘的第一外围子区域和不邻近第一边缘的第二外围子区域。在第一液晶区域的外围区域涂覆第二封框胶时，可以在第一外围子区域和第二外围子区域涂覆第二封框胶，也可以仅在第一外围区域涂覆第二封框胶，而在第二外围子区域涂覆第一封框胶。本公开实施例以在第一外围区域中涂覆第二封框胶，在第二外围子区域涂覆第一封框胶为例进行说明。例如，图9示出了根据本公开一个实施例的在第一液晶区域的第一外围子区域涂覆第二封框胶的方法流程图，该方法包括：
步骤50121、在每个第一液晶区域的第一外围子区域中涂覆第二封框胶。
图10示出了根据本公开的一个实施例的在每个第一液晶区域1021的邻近第一边缘a1的第一外围子区域中涂覆第二封框胶30后的结构示意图，结合图6和图10，第二封框胶30位于第一液晶区域1021的第一外围子区域中， 即第一液晶区域的外围区域中邻近第一边缘a1的区域，该第二封框胶30中设置有第二支撑结构，且邻近第一母板10的第一边缘a1的所有第一液晶区域1021的第一外围子区域的第二封框胶30一体形成，也即是，邻近第一母板10的第一边缘a1的所有第一液晶区域1021的第一外围子区域的第二封框胶30是通过一次涂覆形成的，当然，实际实施中，也可以在每个第一液晶区域1021的外围区域1022中邻近第一边缘a1的第一外围子区域单独涂覆第二封框胶30，本公开实施例对此不作限定。
在本公开实施例中，第二支撑结构的高度可以大于第一支撑结构的高度。该第二支撑结构可以呈球体，且该第二支撑结构的高度为球体的直径，例如，该第二支撑结构可以为硅球、塑料球和玻璃纤维球中的至少一种。当然，实际实施中，第二支撑结构也可以为其他形状，例如，第二支撑结构可以为圆柱体、棱柱体等，本公开实施例对此不作限定。在本公开实施例中，第二支撑结构的高度的取值范围可以包括3.8微米～4.6微米，当该第二支撑结构呈球体时，也即是，该第二支撑结构的直径的取值范围包括3.8微米～4.6微米。实际实施中，该第二支撑结构的高度的取值可以根据需要设置，本公开实施例对此不作限定。

需要说明的是，实际应用中，上述步骤50121与上述步骤50122的先后顺序可以互换，本公开实施例对此不作限定。还需要说明的是，本公开实施例中，在中央液晶区域的外围区域涂覆第一封框胶，在第一液晶区域的外围区域涂覆第二封框胶，还可以在第二液晶区域的外围区域涂覆封框胶，且根据第二距离与第一距离的大小之间的关系，可以在第二液晶区域的外围区域涂覆第一封框胶，也可以在第二液晶区域的外围区域涂覆第二封框胶，请参考下述步骤5013和步骤5014。
步骤5013、当第二距离小于第一距离时，在第二液晶区域的外围区域涂覆第一封框胶。
在本公开的一个实施例中，如步骤501所述，第一距离为d1，第二距离为d2，可以先将第二距离d2与第一距离d1进行比较来确定第二距离d2与第一距离d1的大小关系，当第二距离d2小于第一距离d1时，可以在第二液晶区域的外围区域涂覆第一封框胶。本步骤以第二距离d2小于第一距离d1为例进行说明。
图12示出了根据本公开实施例的在第二液晶区域1031的外围区域1032涂覆第一封框胶20后的结构示意图，结合图6和图12，第一封框胶20位于第二液晶区域1031的外围区域1032中，每个第二液晶区域1031的外围区域1032中的第一封框胶20可以一体成形，该第一封框胶20中可以设置有第一支撑结构。

在本公开的一个实施例中，如步骤501所述，第一距离为d1，第二距离 为d2，可以先将第二距离d2与第一距离d1进行比较来确定第二距离d2与第一距离d1的大小关系，当第二距离d2大于或等于第一距离d1时，可以在第二液晶区域的外围区域涂覆第二封框胶。本步骤以第二距离d2大于或等于第一距离d1为例进行说明。
图13示出了根据本公开的一个实施例的在第二液晶区域1031的外围区域1032涂覆第二封框胶30后的结构示意图，结合图6和图13，可以在第二液晶区域1031的外围区域1032的第三外围子区域中涂覆第二封框胶30，在第二液晶区域1031的外围区域1032的第四外围子区域中涂覆第一封框胶20，其中，第三外围子区域指的是第二液晶区域1031的外围区域1032中邻近第二边缘a2的区域，第四外围子区域指的是在第二液晶区域1031的外围区域1032中除邻近第二边缘a2的区域之外的区域中，且涂覆在第四外围子区域中的第一封框胶20可以一体成形，该第一封框胶20中可以设置有第一支撑结构。
需要说明的是，实际实施中，当第二距离d2大于或等于第一距离d1时，如图14所示，在第一液晶区域1021的外围区域1022中涂覆第二封框胶30时，可以在第一液晶区域1021的外围区域1022中邻近第一边缘a1的区域(即第一外围子区域)中和邻近第二边缘a2的区域(即第三外围子区域)中均涂覆第二封框胶30，在第一液晶区域1021的外围区域1022中除邻近第一边缘a1的区域和除邻近第二边缘a2的区域均涂覆第一封框胶20，且邻近第二边缘a2的区域中的所有的第二封框胶30一体成形。
步骤502、将第二母板与第一母板对盒，并在每个液晶区域内设置液晶，得到液晶母板。
在本公开的实施例中，第二母板可以为阵列母板，也可以为对置母板，当步骤501中的第一母板为阵列母板时，该第二母板为对置母板，当步骤501中的第一母板为对置母板时，该第二母板为阵列母板。例如，图15示出了本公开的一个实施例的将第二母板与第一母板对盒得到液晶母板的流程图，参见图15，该方法包括：
步骤5021、将第二母板与第一母板对盒，每个液晶区域内设置有液晶。
例如，可以在第一母板的每个液晶区域滴注液晶，然后将第二母板设置在第一母板滴注有液晶的一侧，并向第一母板和第二母板施加对盒力，使将第二母板与第一母板对盒，每个液晶区域内设置有液晶。示例地，请参考图 16，其示出了根据本公开一个实施例的在第一母板10的每个液晶区域滴注液晶40后的结构示意图，参见图16，中央液晶区域1011、第一液晶区域1021和第二液晶区域1031中设置有液晶40。本公开实施例中，在第一母板10的每个液晶区域滴注液晶40后，可以将第二母板(图16中未示出)设置在第一母板10滴注有液晶40的一侧，并向第一母板10和第二母板施加对盒力，使将第二母板与第一母板10对盒，每个液晶区域内设置有液晶40。
步骤5022、对封框胶进行固化，得到液晶母板。
封框胶(包括第一封框胶20和第二封框胶30)中通常包含热固化成分和光敏成分。可选地，可以先将对盒的第二母板与第一母板设置在紫外线(英文：Ultraviolet；简称：UV)固化室中，采用紫外光照射封框胶(包括第一封框胶20和第二封框胶30)，使封框胶中的光敏成分在紫外光的照射下固化，之后将对盒的第二母板与第一母板设置在高温炉中对封框胶(包括第一封框胶20和第二封框胶30)进行加热，使封框胶中的热固化成分固化。当然，实际实施中，也可以先对封框胶中的热固化成分进行固化，再对封框胶中的光敏成分进行固化，本公开实施例对此不作限定。
步骤503、沿液晶母板的切割线对液晶母板进行切割，得到多个显示面板，切割线在第一母板上的正投影位于每两个相邻的液晶区域之间。
将第二母板与第一母板对盒得到液晶母板之后，可以沿液晶母板的切割线对液晶母板进行切割，得到多个显示面板，该切割线在第一母板上的正投影可以位于每两个相邻的液晶区域之间，且该切割线在在第一母板上的正投影位于液晶区域的外围区域之外。其中，沿液晶母板的切割线对液晶母板进行切割的实现过程可以参考相关技术，本公开实施例在此不再赘述。
可选地，请参考图17，其示出了根据本公开的一个实施例的从液晶母板的第一周边区域(液晶母板的第一周边区域在第一母板上的正投影与第一母板的第一周边区域重合)切割下来的显示面板的结构示意图，图18是图17所示的显示面板的立体结构示意图，参见图17和图18，该显示面板包括对盒成形的第一基板102(包括第一母板10的第一液晶区域1021和该第一液晶区域1021的外围区域1022)和第二基板(第二母板上与第一基板对应的部分，图17和图18中均未示出)，该显示面板的液晶区域的一个外围区域涂覆有第二封框胶30，其余三个外围区域涂覆有第一封框胶20，该第二封框胶30中设置的第二支撑结构301的高度大于该第一封框胶20中设置的第一支 撑结构201的高度。
需要说明的是，本公开实施例是以从液晶母板的第一周边区域切割下来的显示面板为例进行说明的，从液晶母板的中央区域(液晶母板的中央区域在第一母板上的正投影与第一母板的中央重合)切割下来的显示面板的结构可以参考图2和图3，本公开实施例在此不再赘述。
还需要说明的是，包含在根据本公开实施例的显示面板的制造方法中的步骤的先后顺序可以进行适当调整，步骤也可以根据实际情况进行相应增减，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化的方法，都应涵盖在本公开的保护范围之内，因此不再赘述。
综上所述，在根据本公开实施例的显示面板的制造方法中，由于中央液晶区域不与第一母板的边缘相邻，第一液晶区域与第一母板的边缘相邻，且涂覆在第一液晶区域的外围区域的第二封框胶中的支撑结构的高度大于涂覆在中央液晶区域的外围区域的第一封框胶中的支撑结构的高度，这样一来，在将第二母板与第一母板对盒的过程中，位于第一液晶区域的外围区域的封框胶中设置的支撑结构向第一母板施加的对盒力与位于中央液晶区域的外围区域的封框胶中设置的支撑结构向第一母板施加的对盒力可以趋于相等，第一母板受力趋于均匀，消除了从液晶母板的外围区域切割下来的显示面板的显示效果与从液晶母板的中央区域切割下来的显示面板的显示效果之间的差异，有助于使从液晶母板上切割下来的不同显示面板的显示效果一致。
根据本公开实施例的显示面板的制造方法所制成的显示面板中的一条或两条边与其他的边的支撑盒厚不同，可以减小或者消除显示面板的显示效果的差异。
本公开的至少一个实施例还提供了一种显示面板，该显示面板的一个或两个边的封框胶中设置的支撑结构的高度大于该显示面板的其余的边的封框胶中设置的支撑结构的高度，该支撑结构可以为硅球。图17和图18示出了根据本公开实施例的显示面板。
以上所述仅是本公开的示范性实施方式，而非用于限制本公开的保护范围，本公开的保护范围由所附的权利要求确定。
