Description

显示面板及显示装置 技术领域
本公开涉及显示设备技术领域，并且具体涉及一种显示面板及显示装置。
背景技术
现有的液晶显示面板包括彩膜基板和阵列基板，两基板之间为液晶层。液晶层的厚度(即盒厚)主要通过阵列基板和彩膜基板之间的隔垫物来进行控制，液晶层的厚度对液晶面板的结构和显示均一性有重要的影响。
目前，为了保持显示面板的显示区域和周边区域的盒厚的均一性，通常以基板的中心为中心对称设置支撑部件。但是由于材料原因，支撑部件会一直析出杂质离子，杂质离子进入显示区域后，容易产生残影现象，影响显示效果。在绑定(bonding)区域内，引线会产生电场，在电场的作用下，支撑部件更容易析出杂质离子，且杂质离子更容易被吸引到液晶显示面板的显示区域，使得残影现象更为严重。
因此，亟需一种能够避免或减少显示区域内产生残影现象的显示面板及显示装置。

具体实施方式
为使本领域技术人员更好地理解本公开的技术方案，下面结合附图和示例性实施例对本公开作进一步详细描述。
第一示例性实施例
如图1所示，本公开的第一示例性实施例提供一种显示面板，该显示面板包括第一基板1、第二基板2和辅助挡墙3。第一基板1与第二基板2层叠设置。辅助挡墙3位于第一基板1和第二基板2之间，并且位于显示面板的周边区域，即位于第一基板1和第二基板2的正对部分的边缘区域中。
在本示例性实施例中，第一基板1为彩膜基板，第二基板2为阵列基板。如图1所示，第一基板1、第二基板2和显示面板均呈矩形。第二基板2包括绑定区域20，绑定区域20位于第一基板1和第二基板2的正对部分外部且与该正对部分相接，绑定区域 20所在的第二基板2的一端的长边缘为显示面板的第四边缘24，与该显示面板的第四边缘24相邻的两个相对设置的边缘分别为显示面板的第一边缘21和第二边缘22，与显示面板的第四边缘24相对设置的边缘为显示面板的第三边缘23。
辅助挡墙3包括第一挡墙31，第一挡墙31沿显示面板的第一边缘21和第二边缘22设置。也就是说，在本示例性实施例中，第一挡墙31包括彼此相对设置的第一子部分311和第二子部分312，第一子部分311邻近显示面板的第一边缘21，并与第一边缘21平行，而第二子部分312邻近显示面板的第二边缘22，并与第二边缘22平行，即第一子部分311和第二子部分312平行设置。更具体而言，第一子部分311和第二子部分312分别位于与正对部分的第一边缘21和第二边缘22对应的区域中。应当理解的是，根据显示面板的实际应用情况，第一子部分311和第二子部分312可以是不平行的，以便于显示面板的多样化设计。例如，当显示面板的形状为三角形时，第一子部分311和第二子部分312可以交叉。
辅助挡墙3可以设置在第一基板1上，也可以设置在第二基板2上。
需要说明的是，绑定区域20内设置有多条引线201，各引线201位于绑定区域20与显示区域(其位于上述正对部分的中央或显示面板的中央)对应的位置(即中间位置)，由于第一挡墙31位于显示面板的周边区域，因此，第一挡墙31与最外侧的引线201之间具有一定的距离，从而使第一挡墙31可以避开绑定区域20内的引线201。
本示例性实施例提供的显示面板，通过在第一基板1和第二基板2之间设置包括第一挡墙31的辅助挡墙3(第一挡墙31沿显示面板与绑定区域20所在边缘24相邻的两个相对边缘21和22设置，或第一子部分311和第二子部分312分别位于与正对部分的第一边缘21和第二边缘22对应的区域中)，使辅助挡墙3避开绑定区域20内的引线，由此减少了被绑定区域20内的引线所 形成的电场吸引的显示区域的辅助挡墙3析出的杂质离子的数量，从而解决了残影的问题，保证了显示面板的显示效果。
第二示例性实施例
本示例性实施例提供一种显示面板，第二示例性实施例的显示面板与第一示例性实施例的显示面板的区别在于：第一挡墙31的分布形态不同。
具体而言，如图2所示，在第二示例性实施例中，第一挡墙31呈“冂”字型。更具体而言，第一挡墙31还包括第三子部分313，第三子部分313位于同上述正对部分的与绑定区域20所在边缘24相对的第三边缘23对应的区域中，或沿显示面板的第三边缘23设置，也就是说，第一挡墙31包括三个子部分311、312、313，这三个子部分分别沿显示面板的第一边缘21、第三边缘23和第二边缘22设置且相互连接，从而形成具有开口的“冂”字型结构，所述开口朝向绑定区域20。
第二示例性实施例的显示面板的其他结构与第一示例性实施例的显示面板的结构相同，在此不再赘述。
第三示例性实施例
本示例性实施例提供一种显示面板，第三示例性实施例的显示面板与第二示例性实施例的显示面板的区别在于：辅助挡墙不但包括第一挡墙，还包括第二挡墙。
如图3所示，除了第一挡墙31之外，辅助挡墙3还包括第二挡墙32，第二挡墙32位于第一挡墙31邻近显示面板的显示区域(其位于上述正对部分的中央)的一侧，即第一挡墙31相对于第二挡墙32更邻近显示面板的边缘，位于第二挡墙32的外侧。
在本示例性实施例中，第二挡墙32与第一挡墙31平行设置。也就是说，第二挡墙32的分布形态与第一挡墙31的分布形态相同，即第二挡墙32也包括三个子部分，这三个子部分分别沿显示面板的第一边缘21、第三边缘23和第二边缘22设置且相互连接， 同样形成具有开口的“冂”字型结构，所述开口朝向绑定区域20。
需要说明的是，在本示例性实施例中，是以第一挡墙31和第二挡墙32均呈“冂”字型结构为例进行说明的，但是当第一挡墙31为第一示例性实施例的结构时，即第一挡墙31沿显示面板的第一边缘21和第二边缘22设置时，第二挡墙32也沿显示面板的第一边缘21和第二边缘22设置。当然，本领域技术人员可知，在这种情况下，第二挡墙32也可以呈“冂”字型结构，即沿显示面板的第一边缘21、第三边缘23和第二边缘22设置。
在第一基板1和第二基板2对盒的过程中，会向显示面板施加压力，从而使显示面板周边区域内的卡条、边框受力过大，造成损坏。为了解决这种问题，第一挡墙31的高度可以设置为大于第二挡墙32的高度，这样可以使第一挡墙31分担一部分压力，避免卡条、边框损坏。需要说明的是，第一挡墙31的高度也可以与第二挡墙32的高度相等，这样可以提高显示面板盒厚的稳定性和均一性。
第三示例性实施例的显示面板的其他结构与第二示例性实施例的显示面板的结构相同，在此不再赘述。
第四示例性实施例
本示例性实施例提供一种显示面板，第四示例性实施例的显示面板与第三示例性实施例的显示面板的区别在于：辅助挡墙不但包括第一挡墙和第二挡墙，还包括第三挡墙。
如图4所示，除了第一挡墙31和第二挡墙32之外，辅助挡墙3还包括第三挡墙33，第三挡墙33沿显示面板的绑定区域20所在边缘(即第四边缘24)设置，且位于上述正对部分邻近绑定区域20的一侧。
为了避免绑定区域20内的引线201产生的电场对第三挡墙33产生影响，在本示例性实施例中，第三挡墙33邻近绑定区域20内引线201的第一端331与绑定区域20内最外侧的引线201在平行于第三挡墙33的方向上具有第一间隙d1，也就是说，第三 挡墙33并未延伸至引线201所在的区域，而是位于引线201的外侧。在本示例性实施例中，d1小于或等于20微米。第三挡墙33的另一端(即第二端332)与第一挡墙31的端部相对应。
此外，第三挡墙33在第二基板2上的正投影在垂直于第三挡墙33的方向上与绑定区域20靠近显示区域或上述正对部分的边缘的延长线之间具有第二间隙d2。在本示例性实施例中，d2大于或等于5微米。
在本示例性实施例中，第三挡墙33呈一字型，即第三挡墙33具有连续的线型结构。
第三挡墙33的高度大于或等于第二挡墙32的高度，第三挡墙33的高度与第一挡墙31的高度不限，在本示例性实施例中，第三挡墙33的高度等于第一挡墙31的高度。
在本示例性实施例中，第一挡墙31的高度、第二挡墙32的高度、第三挡墙33的高度可以均相等，从而可以提高盒厚的稳定性和均一性。或者，第一挡墙31的高度大于第二挡墙32的高度，且第三挡墙33的高度大于第二挡墙32的高度，从而可以缓解周边区域内卡条和边框上的压力。
第四示例性实施例的显示面板的其他结构与第三示例性实施例的显示面板的结构相同，在此不再赘述。
第五示例性实施例
本示例性实施例提供一种显示面板，第五示例性实施例的显示面板与第四示例性实施例的显示面板的区别在于：第三挡墙33的结构不同。
如图5所示，在第五示例性实施例中，第三挡墙33具有不连续的线型结构，即第三挡墙33具有缝隙。相对于第四示例性实施例中呈一字型的第三挡墙33，不连续的线型结构可以在第一基板1与第二基板2对盒过程中，便于将液晶层中的气体从第三挡墙33的缝隙中排出，从而避免气体残留在显示面板内部，影响显示效果。
第五示例性实施例的显示面板的其他结构与第四示例性实施例的显示面板的结构相同，在此不再赘述。
第六示例性实施例
本示例性实施例提供一种显示装置，所述显示装置包括如第一示例性实施例至第五示例性实施例中任一示例性实施例所述的显示面板。该显示面板的具体结构在此不再赘述。
本示例性实施例提供的显示装置包括显示面板，通过在第一基板1和第二基板2之间设置包括第一挡墙31的辅助挡墙3(第一挡墙31沿显示面板与绑定区域20所在边缘24相邻的两个相对边缘21和22设置，或第一子部分311和第二子部分312分别位于与正对部分的第一边缘21和第二边缘22对应的区域中)，使辅助挡墙3避开绑定区域20内的引线，由此减少了被绑定区域20内的引线所形成的电场吸引的显示区域的辅助挡墙3析出的杂质离子的数量，从而解决了残影的问题，保证了显示面板的显示效果。
可以理解的是，以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式，然而本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本公开的保护范围。
