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它实施例，都属于本发明保护的范围。
在研究中，本申请的发明人注意到，为了实现显示面板中的公共电极与公共电极线之间的电连接，需要额外增加制备导电元件的步骤，如：丝网印刷或点导电银胶的步骤，这无疑造成显示面板制作过程的复杂化。
实施例一
本实施例提供一种显示装置，如图1、2a和2b所示，该显示装置包括：第一基板S1和与第一基板S1相对设置的第二基板S2；第一基板S1的显示 区Area1内具有公共电极6，边框区Area2内具有多个第一突起1，第一突起1包括第一突起主体11及位于第一突起主体11顶端的第一接触电极12，第一接触电极12与公共电极6电连接；第二基板S2的边框区Area2内具有第一公共电极信号线(例如，第一公共电极电压信号线)5，第一接触电极12与第一公共电极信号线5电连接。
本实施例所提供的显示装置通过在第一基板S1的边框区Area2内设置第一突起1，第一突起1的结构包括第一突起主体11及位于第一突起主体11顶端的第一接触电极12，使得第二基板S2上的第一公共电极信号线5能够通过第一接触电极12与第一基板S1上的公共电极电连接，这种结构的显示装置无需为电连接第一公共电极信号线与第一接触电极额外进行丝网印刷导电金球或点导电银胶的步骤，有利于简化显示装置的制作步骤。
由于显示装置的显示区Area1内具有用于支撑显示屏盒厚的隔垫物，因此，例如，可使第一突起主体11与显示区Area1内的隔垫物在相同的步骤中形成，从而无需额外增加制备第一突起主体11的步骤，进一步的简化了装置的制作步骤。
需要说明的是，为了减小显示屏显示区Area1所受的应力，可将显示区Area1内的隔垫物进行这样的设计：显示区Area1内的隔垫物包括第一隔垫物和第二隔垫物，第一隔垫物的高度大于第二隔垫物的高度，从而二者之间形成段差，在显示屏受到按压时，第二隔垫物的存在能够给予显示屏一定的支撑力。基于前述结构，例如，可使第一突起1的高度与第一隔垫物的高度相同，第一突起主体11与第二隔垫物的高度相同。例如，制备时可采用灰阶掩膜工艺在一次构图中形成第一突起主体11、第一隔垫物和第二隔垫物，使第一隔垫物与第二隔垫物之间形成段差。
由于第一基板S1上具有公共电极，因此，例如，可使第一接触电极12与公共电极同层形成，从而将第一接触电极12与公共电极的制备步骤合二为一，进一步简化了制作步骤。
需要说明的是，第一接触电极12可仅包括位于第一突起主体11顶端的部分，也可包覆整个第一突起主体11的除与第一基板S接触的一面外的其余表面(如图2a中所示)。
如图1所示，本实施例中，可在显示装置至少一边对应的边框区内设置 第一突起1。例如：若需要在四条边均构成电连接，则可在这四条边对应的边框区内设置第一突起1；例如，在一条边所对应的边框区中，可使第一突起1均匀分布，使公共电极各部分的信号延迟保持一致；例如，可使相对的两条对边所对应的边框区内第一突起的分布情况对称，以减少信号的损耗。
例如，第一突起主体11的形成材料可为绝缘材料，如树脂，以避免传导至第一接触电极12上的电信号通过第一突起主体11传导至其下方(即第一突起主体11与第一基板S1之间)的膜层中，造成信号的损耗。
本实施例中，第一基板S1可为一彩膜基板，则在第一突起1的下方还可具有黑矩阵层、彩膜层和光学胶层。
如图2b所示，第二基板S2可为一阵列基板，其显示区Area1内可具有多条公共电极线7，该些公共电极线7例如可与第一公共电极信号线5电连接，从而可利用第一公共电极信号线5向第一基板S1上的公共电极和第二基板S2上的公共电极线同时供电，有利于减少外围布线的数量；或者，可在第二基板S2的边框区Area2内单独设置第二公共电极信号线(例如，第二公共电极电压信号线)5′，使公共电极线7与第二公共电极信号线5′电连接，即利用第二公共电极信号线向公共电极线供电，从而可实现分别单独的向第一基板S1上的公共电极和第二基板S2上的公共电极线供电，使公共电极和公共电极线能够具有不同的电位。
实施例二
为减小边框区的应力，本实施例所提供的显示装置在边框区内设置第二突起，与第一突起形成段差。
如图3和图4所示，显示装置的第一基板S1的边框区Area2内既具有第一突起1，又具有第二突起2，第二突起2的高度小于第一突起1的高度，从而使第一突起1与第二突起2之间形成段差，减小显示屏在受到按压时的应力，消除显示屏局部应力过大造成的显示质量下降的问题。
第一突起1包括第一突起主体11和第一接触电极12，第二突起2顶端不具有接触电极。例如，第二突起2可与第一突起主体11同层形成，将制备第一突起主体11和第二突起2的步骤合二为一，进一步的简化制作步骤。例如，可在相同的步骤下同时制备第一突起主体11、第二突起2、显示区Area1中的第一隔垫物和第二隔垫物，进一步简化制作步骤。
如图3和5所示，可在第一基板S1的至少一条边所对应的边框区内同时设置第一突起1和第二突起2。例如：若需要在四条边均构成电连接，则可在这四条边对应的边框区内设置第一突起1，并设置第二突起2。例如，在一条边所对应的边框区内，可在相邻两个第一突起1之间设置至少一个第二突起2，以进一步减少边框区Area2的应力，使边框区Area2各部分的应力均匀；更进一步的是，例如，在一条边所对应的边框区内，可使第一突起1和第二突起2等间隔分布，以保持使公共电极各部分信号延迟的一致性和显示屏各部分受力的均匀性。
实施例三
本实施例所提供的显示装置，其第一基板S1边框区Area2内的突起高度一致，通过在第二基板S2的边框区Area2内设置第三突起形成段差。
如图6、图7、图8和图9所示，第一基板S1的边框区Area2内仅具有第一突起1，即突起的高度一致，第二基板S2的边框区Area2内具有数量小于第一突起1的多个第三突起3，每个第三突起3均与一个第一突起1的位置相对应，第三突起3包括第三突起主体31及位于第三突起主体31顶端的第二接触电极32，第二接触电极32与第一公共电极信号线电连接，且第二接触电极32与第一接触电极12相接触。由于第三突起3的数量小于第一突起1，因此在垂直于显示装置的方向上，第一突起1和第三突起3均存在的位置处显示屏盒厚会大于其余位置处的显示屏盒厚，从而在显示屏中形成段差，有利于减小显示屏在受到按压时的应力。
例如，如图7所示，可通过对应一部分第一突起1设置第三突起3且对应其余第一突起1不设置突起的方式，实现段差的形成。
如图8和图9所示，可在第二基板S2的边框区Area2内设置多个第四突起4，使第四突起4与第三突起3的数量之和等于第一突起1的数量，每个第四突起4均与一个第一突起1的位置相对应，第四突起4的高度小于第三突起3的高度，实现段差的形成。通过设置第四突起4可使边框区Area2内的段差不至于过大，进一步减小应力。
第四突起4的结构可如图8所示，包括第四突起主体41及位于第四突起主体41顶端的第三接触电极42，在第四突起4对应的位置受到挤压后，第三接触电极42与第一公共电极信号线电连接且能够与第一接触电极12接触， 从而使第四突起4对应的位置处的公共电极能够直接通过第三接触电极42和第一接触电极12得到电压，减少了电信号的损耗。例如，可使第四突起主体41的高度小于第三突起主体31的高度，且第三接触电极42与第二接触电极32同层形成，从而将第二接触电极32与第三接触电极42的制备步骤合二为一，有利于简化制作步骤。
第四突起4的结构还可如图9所示，其整体可与第三突起主体31同步形成，顶端不具有电极。
第二基板S2上具有多层薄膜，第三突起主体31可由多层薄膜中的至少两层层叠形成，从而在形成第二基板S2上的多层薄膜的同时形成了第三突起主体31，节省了制作步骤。基于此，对于图8所示出的结构，第四突起主体41可由多层薄膜中的至少一层层叠形成，且形成第三突起主体31的薄膜的层数大于形成第四突起主体41的薄膜的层数，从而使第四突起主体41的高度小于第三突起主体31的高度，第四突起主体41的形成步骤同样也可兼容于形成多层薄膜的步骤中；对于图9所示出的结构，第三突起主体31和第四突起4均由多层薄膜中的至少一层层叠形成，且形成第三突起主体31的薄膜与形成第四突起4的薄膜相同，但是第四突起4的顶端不具有电极，从而也可使第四突起4的高度小于第三突起3的高低，且使形成第四突起4的步骤与形成多层薄膜的步骤合并。
需要进一步说明的是，本实施例中第二基板S2可为一阵列基板，其所包括的多层薄膜可包括栅极金属层、栅极绝缘层、有源层、源漏金属层、钝化层、平坦化层和像素电极层等，构成第三突起主体31的薄膜可为前述各薄膜中的至少两种。例如，可利用栅极金属311和源漏极金属312形成第三突起主体31，从而第三突起3的电阻为第二接触电极32、栅极金属311和源漏极金属312并联的电阻，减小了第三突起3的电阻，即减小了从第一公共电极信号线到公共电极的传输电阻，减少了电信号在传导过程中的损失；在该示例中，第二接触电极32、栅极金属311和源漏极金属312之间可通过过孔或直接接触进行电连接。进一步的，对于图8所示出的结构，第四突起主体41的形成材料例如可为栅极金属或源漏源极金属，以减小第四突起4整体的电阻；对于图9所示出的结构，第四突起4例如可由栅极金属311和源漏极金属312构成。
需要说明的是，栅极金属311并不与阵列基板上的栅极和栅线电连接，源漏极金属312并不与阵列基板上的源极、漏极和数据线电连接。
第二接触电极32和第三接触电极42例如可与像素电极同层形成，但不与像素电极电连接，从而将第二接触电极32、第三接触电极42和像素电极的制备步骤合并，简化了制作工艺。此外，例如，第二基板S2上的公共电极线可与栅极金属同层形成，因此第二接触电极32和第三接触电极42可通过过孔与公共电极线电连接。
实施例四

例如，第一基板的边框区还具有多个第二突起，第二突起的高度小于第一突起的高度。
例如，第二基板的边框区内具有数量小于第一突起的多个第三突起，每个第三突起均与一个第一突起的位置相对应，第三突起包括第三突起主体及位于第三突起主体顶端的第二接触电极，第二接触电极与第一公共电极信号线电连接，且第二接触电极与第一接触电极相接触。
例如，第二基板的边框区内还具有多个第四突起，第四突起与第三突起的数量之和等于第一突起的数量，每个第四突起均与一个第一突起的位置相对应，第四突起的高度小于第三突起的高度。
本实施例提供的制作方法中各结构的设计可参考上述实施例一至实施例三中的相关描述，重复之处不再赘述。
该显示装置的制作方法还可以包括将第一基板与第二基板之间注入液晶以形成液晶盒等步骤。在一些实施例中，该制作方法还可以包括在第二基板的远离第一基板的一侧设置背光源以便为显示装置提供背光的步骤。此处不做赘述。
本发明实施例所提供的显示装置及其制作方法中，显示装置包括相对设 置的第一基板和第二基板，第一基板的显示区内具有公共电极，第二基板的边框区内具有用于向公共电极输送公共电极电压的公共电极信号线，通过在第一基板的边框区内形成多个第一突起，第一突起包括第一突起主体及位于第一突起主体顶端的第一接触电极，使公共电极能够通过该第一接触电极实现与第一公共电极信号线的电连接，从而省略了为实现第一接触电极与第一公共电极信号线电连接而丝网印刷导电金球或点导电银胶的步骤，简化了显示装置整体的制作步骤。
