附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例的附图作简单地介绍，显而易见地，下面描述中的附图仅仅涉及本发明的一些实施例，而非对本发明的限制。
图1为一种显示母板的平面示意图；
图2为一种零切割的显示母板的平面示意图；
图3为本公开的实施例的显示母板的平面示意图；
图4为本公开实施例的显示母板的截面示意图。
其中附图标记为：1、显示母板；01、第一基板；02、第二基板；10、显示基板；11、密封胶；12、显示区域；13、第一密封区域；14、第二密封区域。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明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发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，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，都属于本发明保护的范围。
图1为一种显示母板的平面示意图。如图1所示，对于同一张显示母板1上的各个显示基板10的密封胶11的涂覆通常采用，逐一对每一个显示基板10的密封区域进行涂覆的方式，而这种涂覆使显示基板10的四角的密封胶11较为厚大，从而将会导致角漏光，严重影响量产的可能性。图2为零切割的显示母板的平面示意图。如图2所示，当使用这种密封胶11涂覆零切割(所谓的零切割是指：切割刀轮直接切到胶)显示基板10时，又会导致两个显示基板10交汇处的拐角出现空白气泡，即密封胶11未能全部覆盖的现象，最终导致显示母板1切割的不良。
图3为本公开的实施例的显示母板的平面示意图。如图3所示，本实施例提供一种显示母板的制备方法，其中显示母板1包括多行第一密封区域13和多列第二密封区域14，所述第一密封区域13和所述第二密封区域14交叉位置限定出多个显示区域12；所述制备方法包括：采用直线式涂覆方式，对所述第一密封区域13和所述第二密封区域14涂覆密封胶11的步骤。
例如，可以是先准备第一基板，该第一基板包括多行第一密封区域和多列第二密封区域，所述第一密封区域和所述第二密封区域彼此交叉以限定出多个显示区域；然后，在所述第一基板的所述第一密封区域和所述第二密封区域沿直线涂覆密封胶。
在需要说明的是，在本实施例中并不对第一密封区域13和第二密封区域14的涂覆顺序做限定，也就是说，可以依次涂覆第一密封区域13之后再依次涂覆第二密封区域14，也可以依次涂覆第二密封区域14之后再依次涂覆第一密封区域13，当然还可以交叉着对第一密封区域13和第二密封区域14进行涂覆。
在本实施例中采用直线式涂覆方式对第一密封区域13和第二密封区域14涂覆密封胶11，因此可以从根本上有效降低每个显示区域12四角的密封胶11肥大问题，而可以理解的是显示母板1上每一个显示区域12则对应之后切割所形成的显示基板的显示区域，环绕显示母板1的显示区域12的密封胶11也就对应之后的切割所形成的显示基板的密封胶11，从而可以降低所形成的显示基板的四角漏光的比率。另外，从图3中可以看出，相邻的显示区域12周围的密封胶11是共用的，因此在对显示母板1切割形成显示面板时，可以沿第一密封区域13的中线和第二密封区域14的中线进行切割，因 此可以完全规避所形成的显示基板四角密封胶11未填满的现象，有效的提高了切割良率，增加了零切割窄边框设计的量产的可能性。
显示母板1上的第一密封区域13和第二密封区域14是垂直设置的，因此，可以限定出多个矩形的显示区域12，则可以切割成所多个矩形显示基板。当然还可以根据所需要形成的产品形状来限定第一密封区域13和第二密封区域14的方向。只要保证这两个区域是延伸方向是直线即可。
例如，在每个所述第一密封区域沿在行方向上延伸的直线涂覆密封胶，在每个所述第二密封区域沿在列方向上延伸的直线涂覆密封胶。
例如，在涂覆密封胶时，对每个所述第一密封区域和每个所述第二密封区域沿所述直线连续涂覆密封胶。在本实施例中，不是针对每个显示区域周围的密封区域单独涂覆，避免了在每个显示区域边角处密封胶的厚大。
在第一基板上涂覆密封胶后，将第二基板贴合到所述第一基板，所述第一基板和所述第二基板通过所述密封胶彼此结合。
例如，第一基板为阵列基板母板，第二基板为彩膜基板母板。或者，第一基板为彩膜基板母板，第二基板为阵列基板母板，本公开的实施例对此没有特别限定。
图4为本公开实施例的显示母板的截面示意图。例如，该截面示意图示出了沿图3中的A-A’线剖取的截面。例如，第一基板01和第二基板02通过之间的密封胶彼此结合。
相应的，本实施例还提供了一种显示面板的制备方法，其包括上述形成显示母板1的步骤，以及对所形成的显示母板1沿第一密封区和第二密封区进行切割的步骤。
对显示母板1的第一密封区域13和第二密封区域14进行切割形成显示基板的步骤例如可以是，沿沿所第一密封区的中线和第二密封区的中线进行切割，以形成多个显示基板。
需要说明的是，在本实施例中并不对第一密封区域13和第二密封区域14的切割顺序做限定，也就是说，可以依次第一密封区域13之后再依次切割第二密封区域14，也可以依次第二密封区域14之后再依次切割第一密封区域13，当然还可以交叉着对第一密封区域13和第二密封区域14进行切割。
由于在形成显示母板1时，是采用直线式涂覆方式对第一密封区域13 和第二密封区域14涂覆密封胶11，因此可以从根本上有效降低每个显示基板四角的密封胶11肥大问题，从而可以降低所形成的显示基板的四角漏光的比率。另外，从图3中可以看出，相邻的显示区域12周围的密封胶11是共用的，因此在对显示母板1切割形成显示面板时，在沿第一密封区域13的中线和第二密封区域14的中线进行切割，因此可以完全规避所形成的显示基板四角密封胶11未填满的现象，有效的提高了切割良率，增加了零切割窄边框设计的量产的可能性。
相应的，本实施例中还提供了一种显示母板和一种显示面板，这两者是采用上述方法制成的。
在该显示母板中，例如，位于所述第一密封区域的密封胶和位于所述第二密封区域的密封胶呈直角交叉。
在该显示母板中，例如，相邻的第一密封区域的密封胶和相邻的第二密封区域的密封胶限定出矩形的显示区域。
本公开的实施例还提供一种显示装置，其包括上述显示面板。
本实施例中该显示装置可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
当然本实施例中显示装置还具有常规的显示装置的外框等结构。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
本申请要求于2016年5月6日递交的中国专利申请第201610298530.8号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
