Description

显示面板及其制作方法和显示装置 技术领域
本公开涉及一种显示面板及其制作方法和显示装置。
背景技术
随着科技的发展和社会的进步，超薄、超窄边框高品质液晶显示面板越来越受到人们的青睐，从而使众多显示企业在这些方向上投入了巨大的人力物力进行研发。为了实现液晶显示面板的超窄边框，常规上，位于同一显示面板上的相邻显示屏共用同一封框胶，之后在显示屏切割工艺中在共用的封框胶上进行切割。
但是封框胶固化后硬度比较大。在进行切割的时候，会出现共用的封框胶的中心区域无法完全断裂的情况。这样就无法通过共用封框胶的方法实现超窄边框显示面板的设计，严重的甚至会损坏显示面板，影响显示面板的性能，导致最终形成的显示面板不可用。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动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。
除非另作定义，此处使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”或者“一”等类似词语也不表示数量限制，而是表示存在至少一个。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也相应地改变。
本公开的实施例提供了一种显示面板。如图1至3所示，该显示面板包括：第一基板1、和与第一基板1相对的第二基板2以及设置于第一基板1和第二基板2之间的封框胶3和液晶4。该显示面板包括相邻的显示区域10和11。封框胶3设置于第一基板1和第二基板2的周边区域以及相邻显示区域10和11之间，将第一基板1和第二基板2之间的显示区域10和11密封。液晶4滴注于第一基板1和第二基板2之间的显示区域10和11中。相邻显示区域10和11之间的封框胶3具有预切割位置a-a’。预切割位置a-a’为相邻显示区域10和11之间的封框胶3的中轴线的位置，中轴线的方向为与相邻显示区域10和11之间的封框胶3的线宽所在方向垂直的方向。该显示面板还包括设置于与该预切 割位置a-a’对应位置的固化阻隔层5。
在一个示例中，如图1所示，固化阻隔层5可设置在第一基板1的上表面的与预切割位置a-a’对应的位置处。相邻显示区域10和11之间的封框胶3覆盖固化阻隔层5。这里，相邻显示区域10和11之间的封框胶3覆盖固化阻隔层5指的是，相邻显示区域10和11之间的封框胶3可以至少形成于固化阻隔层5的背离第一基板1的上表面上以及固化阻隔层5的与封框胶3的中轴线平行的相对的两个侧面上。
在另一个示例中，如图2和图3所示，固化阻隔层5还可设置在第二基板2的下表面的与预切割位置a-a’对应的位置。相邻显示区域10和11之间的封框胶3覆盖固化阻隔层5。固化阻隔层5阻挡固化封框胶3的光线比如紫外光，从而在封框胶3的固化工艺中，位于与固化阻挡层5对应的预切割位置a-a的封框胶3不被固化。
当从第一基板1侧进行紫外光照射对封框胶3进行固化时，固化阻隔层5则设置在第一基板1的上表面，如图1所示。当采用从第二基板2侧进行紫外光照射胶3进行固化时，固化阻隔层5设置在第二基板2的下表面，如图2所示。本公开不限于上述的实施例。在实际的设计中，固化阻隔层可以设置在任何位置，只要其在对封框胶进行固化时能够遮挡固化预切割位置的封框胶的光线即可。
在另一示例中，如图4所示，固化阻隔层5还可同时设置在第一基板1的上表面和第二基板2的下表面，且与预切割位置a-a’对应的位置处。
需要说明的是，预设切割位置a-a’为实际进行显示面板的制作工艺中，为了实现窄边框而在封框胶上设置的进行切割的位置。例如，本实施例中的预切割位置为相邻显示区域之间的封框胶的中轴线所在的位置，该中轴线与显示面板的切割方向平行。实际的设计中，显示面板的有效显示区域的四周都设计有对位标记(未显示)。可以根据对位标记设置预切割位置a-a’。本公开中的固化阻隔层5设置在与预切割位置a-a’对应的位置处。这样该位置处的封框胶不会被紫外光照射到，不会固化，切割的时候容易断裂。
例如，第一基板1可以为阵列基板，第二基板2可以为彩膜基板；或者，第一基板1可以为彩膜基板，第二基板2可以为阵列基板。固化 阻隔层5可以为阻挡紫外光的紫外阻隔层。
根据本公开的实施例的显示面板包括：第一基板，和与第一基板相对的第二基板，设置于第一基板和第二基板之间且将将第一基板和第二基板密封的封框胶。封框胶设置于第一基板和第二基板之间，包括周边区域以及相邻显示区域之间。并且，相邻显示区域之间的封框胶具有预切割位置。此外，该显示面板还包括位于与预切割位置对应位置的固化阻隔层，该固化阻隔层设置于第一基板上，或者第二基板上，且被封框胶覆盖。由于封框胶需要进行紫外光固化，固化之后的封框胶的硬度比较大，因此在进行显示屏切割工艺中不容易断裂，会出现断裂面不在相邻的显示区域之间的封框胶的切割位置的情况。本公开中，在相邻的显示区域之间的封框胶的预切割位置的对应位置上设置固化阻隔层。这样在进行紫外光照射固化的时候保证相邻的显示区域之间的预切割位置处的封框胶不会被固化，使得该位置处的封框胶容易断裂。随后进行切割工艺时，可以保证封框胶在预切割位置处断裂，实现了显示屏的窄边框设计。根据本实施例的显示面板，由于断裂位置准确，形成的显示屏可用，不会成为残次品，进而降低了生产成本，提高了显示屏的性能。
进一步地，例如，如图5所示，固化阻隔层5设置在第一基板的上表面上以及第二基板的下表面上，且被封框胶3覆盖。该显示面板还包括设置在第一基板1的上表面上的第一取向层6。固化阻隔层5与第一取向层6同层且设置在与预切割位置a-a’对应的位置处。
固化阻隔层5的材料与第一取向层6的材料相同。
具体地，可以在形成第一取向层6的同时形成与第一取向层6同层的固化阻隔层5，即通过一次工艺形成第一取向层6和固化阻隔层5。例如，可以采用新型的印刷凸版APR板，APR板也具有在与预切割位置对应的位置的凸起。可以在凸起位置放置与第一取向层材料相同的物质，以通过一次工艺形成第一取向层和与第一取向层同层同材质的固化阻隔层。当然，本实施例中只是举例说明如何通过一次工艺形成第一取向层和固化阻隔层，本公开并不限于此。任何可以通过一次工艺形成第一取向层和固化阻隔层的方法都是可行的。
进一步地，如图6所示，该显示面板还包括设置在第二基板2的下表面的第二取向层7。固化阻隔层5与第二取向层7同层且还设置在与预切割位置a-a’对应的位置处。
固化阻隔层5的材料与第二取向层7的材料相同。
具体地，可以在形成第二取向层的同时形成与第二取向层同层的固化阻隔层，即通过一次工艺形成第二取向层和固化阻隔层。例如，可以采用新型的印刷凸版APR板，APR板具有在预切割位置对应的位置的凸起。可以在凸起位置放置与第二取向层材料相同的物质，以通过一次工艺形成第二取向层和与第二取向层同层同材质的固化阻隔层。当然，本实施例中只是举例说明如何通过一次工艺形成第二取向层和固化阻隔层。本公开并不限于此。任何可以通过一次工艺形成第二取向层和固化阻隔层的方法都是可行的。
固化阻隔层的厚度例如为大约
Figure PCTCN2015084552-appb-000002
本公开提供的固化阻隔层还可以只设置为与第一取向层同层且在与预切割位置对应的位置。此时，固化阻隔层的材料可以与第一取向层的材料相同。或者固化阻隔层可以只设置为与第二取向层同层且在与预切割位置对应的位置，固化阻隔层的材料可以与第二取向层的材料相同。
需要说明的是，本实施例中的固化阻隔层的宽度可以在满足覆盖预切割位置的前提下，尽量的小。例如，固化阻隔层在第一基板或第二基板的表面所在位置的区域大小与预切割位置在第一基板或第二基板的表面对应的区域大小相等。也可理解为固化阻隔层的宽度与预切割位置的宽度大小相同。在实现预切割位置的封框胶不被固化的情况下，其它位置的封框胶都可以固化。如果固化阻隔层的宽度过大，最终形成的显示器中未固化的封框胶的面积过大，在封框胶周围的液晶分子可能不能稳定的固定在原来的位置而产生形变，影响最终形成的显示器的显示性能。固化阻隔层的材料此处不作唯一的限定，只要是可以不让紫外光透过且不影响显示器件的显示性能的材料都可以作为固化阻隔层的材料。
根据本公开的实施例的显示面板包括：第一基板，和与第一基板相对的第二基板，第一基板和第二基板之间的周边区域通过设置的封框胶，其将第一基板和第二基板密封，第一基板和第二基板之间的相邻显示区域之间的封框胶具有预切割位置。此外，第一基板上的与预切割位置对应的位置，并且/或者第二基板上的与预切割位置对应的位置设置有固化阻隔层。由于封框胶需要进行紫外光固化，固化之后的封框胶的硬度比较大，在进行显示屏切割工艺中不容易断裂，会出现断裂面不在 相邻显示区域之间的封框胶的切割位置的情况。本公开中在相邻显示区域之间的封框胶的预切割位置上设置固化阻隔层。这样在进行紫外光照射固化的时候保证相邻显示区域之间的封框胶的预切割位置处不会被固化，使得该位置处的封框胶容易断裂，随后进行切割工艺时可以保证封框胶在预切割位置处断裂，实现了显示屏的窄边框设计。根据本实施例的显示面板，由于断裂位置准确，形成的显示屏可用，不会成为残次品，进而降低了生产成本，提高了显示屏的性能。
本公开的实施例提供了一种显示面板的制作方法，如图7所示，该方法包括以下步骤。
101、提供第一基板，和与第一基板相对的第二基板。
102、在面对第二基板的第一基板的表面的与预切割位置对应的位置处形成固化阻隔层。
封框胶覆盖固化阻隔层。
103、在面对第一基板的第二基板的表面的与预切割位置对应的位置形成固化阻隔层。
封框胶覆盖固化阻隔层。
需要说明的是，形成第一基板上的固化阻隔层的步骤102和形成第二基板上的固化阻隔层的步骤103在执行上没有先后顺序之分，在实际的实施中，可以根据具体设计的显示器件的层结构来决定执行顺序。
104、在第一基板和第二基板之间尤其在周边区域设置封框胶以便于将第一基板和第二基板密封。
第一基板和第二基板之间的相邻显示区域的封框胶具有预切割位置。
固化阻隔层的厚度可以例如为约
Figure PCTCN2015084552-appb-000003
在上述的方法中，步骤101之后可以只执行步骤102和104，也可以执行步骤103和104，或者可以执行步骤102至104，具体的执行步骤根据实际中设计的显示器件的层结构来选择。
需要说明的是，预设切割位置为实际进行显示面板的制作工艺中，为了实现窄边框而设置的在封框胶上进行切割的位置。例如，本实施例中的预切割位置为相邻显示区域之间的封框胶的中轴线所在的位置，该中轴线与切割方向平行。在实际的设计中，显示面板的有效显示区域的 四周都设计有对位标记，可以根据对位标记设置预切割位置a-a’。本公开中的固化阻隔层设置在与预切割位置对应的位置处，这样该位置处的封框胶不会被紫外光照射到，不会固化，切割的时候容易断裂。
需要说明的是，本实施例中的固化阻隔层的宽度可以在满足覆盖预切割位置的前提下，尽量的小。例如，形成的固化阻隔层在第一基板或第二基板的表面所在位置的区域大小与预切割位置在第一基板或第二基板的表面对应的区域大小相等。也可理解为使形成固化阻隔层的宽度与预切割位置的宽度大小相同。在实现预切割位置的封框胶不被固化的情况下，其它位置的封框胶都可以固化。保证了产品的良率。
根据本公开的实施例的显示面板的制作方法包括形成第一基板，和与第一基板相对的第二基板，并在第一基板和第二基板之间尤其在周边区域设置封框胶将第一基板和第二基板密封；其中，第一基板和第二基板之间的相邻显示区域之间的封框胶具有预切割位置，然后在第一基板上的与预切割位置对应的位置，并且/或者在第二基板上的与预切割位置对应的位置形成固化阻隔层。由于封框胶需要进行紫外光固化，固化之后的封框胶的硬度比较大，在进行显示屏切割工艺中不容易断裂，会出现断裂面不在相邻显示区域之间的封框胶的切割位置的情况。本公开中在相邻显示区域之间的封框胶的预切割位置上设置固化阻隔层。这样在进行紫外光照射固化的时候保证相邻显示区域之间的封框胶的预切割位置处不会被固化，使得该位置处的封框胶容易断裂，随后进行切割工艺时可以保证封框胶在预切割位置处断裂，实现了显示屏的窄边框设计。根据本实施例的显示面板的制作方法，由于断裂位置准确，形成的显示屏可用，不会成为残次品，进而降低了生产成本，提高了显示屏的性能。
本公开的实施例提供了另一种显示面板的制作方法，如图8所示。该方法包括以下步骤。
201、提供第一基板，和与第一基板相对的第二基板。
202、在面对第二基板的第一基板的表面上形成第一取向层。
203、在预切割位置对应的位置处形成固化阻隔层，其与第一取向层同层。
具体地，步骤203可以通过以下方式来实现。
采用与形成第一取向层相同的工艺，与第一取向层同层且在与预切割位置对应的位置处形成与第一取向层的材料相同的固化阻隔层。
需要说明的是，形成第一取向层的步骤202和形成固化阻隔层的步骤203可以是同时进行的。具体地，可以采用新型的APR板，即APR板具有在与预切割位置对应的位置的凸起，可以在凸起位置放置形成固化阻隔层的物质，以通过一次工艺形成第一取向层和与第一取向层同层同材质的固化阻隔层。当然，本实施例中只是举例说明可以采用新型APR板通过一次工艺形成第一取向层和固化阻隔层。本公开并不限于此，任何可以通过一次工艺形成第一取向层和固化阻隔层的方法都是可行的。
固化阻隔层的材料此处不作唯一的限定，只要是可以不让紫外光透过且不影响显示器件的显示性能的材料都可以作为固化阻隔层的材料。
204、在第一基板和第二基板之间尤其在周边区域设置封框胶以便于将第一基板和第二基板密封。
第一基板和第二基板之间的相邻显示区域之间的封框胶具有预切割位置。
本实施例中在第一基板上的第一取向层同层且在与预切割位置对应的位置处形成固化阻隔层。当采用从第一基板侧进行紫外光照射实现封框胶的固化时，由于固化阻隔层的存在可以有效的保证进行封框胶切割的位置处的封框胶不被固化，进行切割工艺时可以保证封框胶从切割位置断裂，实现了窄边框的设计。
根据本公开的实施例的显示面板的制作方法包括形成第一基板，和与第一基板相对的第二基板，并在第一基板和第二基板之间尤其在周边区域设置封框胶以将第一基板和第二基板密封。第一基板和第二基板之间的相邻显示区域之间的封框胶上具有预切割位置，然后在第一基板上的与预切割位置对应的位置，并且/或者第二基板上的与预切割位置对应的位置形成固化阻隔层。由于封框胶需要进行紫外光固化，固化之后的封框胶的硬度比较大，在进行显示屏切割工艺中不容易断裂，会出现断裂面不在相邻显示区域之间的封框胶的切割位置的情况。本公开中在相邻显示区域之间的封框胶的预切割位置上设置固化阻隔层，这样在进行紫外光照射固化的时候保证共用的封框胶的预切割位置处不会被固 化，使得该位置处的封框胶容易断裂，随后进行切割工艺时可以保证封框胶在预切割位置处断裂，实现了显示屏的窄边框设计。根据本实施例的显示面板的制作方法，由于断裂位置准确，形成的显示屏可用，不会成为残次品，进而降低了生产成本，提高了显示屏的性能。
本公开的实施例提供了又一种显示面板的制作方法，如图9所示。该方法包括以下步骤。
301、形成第一基板，和与第一基板相对的第二基板。
302、在面对第一基板的第二基板的表面上形成第二取向层。
303、在与第二取向层同层且与预切割位置对应的位置处形成固化阻隔层。
具体地，步骤303可以通过以下方式来实现：
采用与形成第二取向层相同的工艺，在与第二取向层同层且与预切割位置对应的位置处形成与第二取向层材料相同的固化阻隔层。
需要说明的是，形成第二取向层的步骤302和形成固化阻隔层的步骤303可以是同时进行的。具体地，可以采用新型的APR板，即APR板与预切割位置对应的位置处也具有凸起，可以在凸起位置放置形成固化阻隔层的物质，通过一次工艺形成第二取向层和与第二取向层同层同材质的固化阻隔层。当然，本实施例中只是举例说明可以采用新型APR板通过一次工艺形成第二取向层和固化阻隔层。本公开并不限于此。任何可以通过一次工艺形成第二取向层和固化阻隔层的方法都是可行的。
固化阻隔层的材料此处不作唯一的限定，只要是可以不让紫外光透过且不影响显示器件的显示性能的材料都可以作为固化阻隔层的材料。
304、在第一基板和第二基板之间的周边区域设置封框胶以便于将第一基板和第二基板密封。

根据本公开的实施例的显示面板的制作方法包括：形成第一基板，和与第一基板相对的第二基板，并在第一基板和第二基板之间尤其在周边区域设置封框胶将第一基板和第二基板密封。第一基板和第二基板之间的相邻显示区域之间的封框胶具有预切割位置，然后在第一基板上的与预切割位置对应的位置，或者第二基板上的与预切割位置对应的位置处形成固化阻隔层。由于封框胶需要进行紫外光固化，固化之后的封框胶的硬度比较大，在进行显示屏切割工艺中不容易断裂，会出现断裂面不在共用的封框胶的切割位置的情况。本公开中在相邻显示区域之间的封框胶的预切割位置上设置固化阻隔层，这样在进行紫外光照射固化的时候保证相邻显示区域之间的封框胶的预切割位置处不会被固化，使得该位置处的封框胶容易断裂，随后进行切割工艺的时可以保证封框胶在预切割位置处断裂，实现了显示屏的窄边框设计。根据本实施例的显示面板的制作方法，由于断裂位置准确，形成的显示屏可用，不会成为残次品，进而降低了生产成本，提高了显示屏的性能。
本公开的实施例提供了又一种显示面板的制作方法。如图10所示，该方法包括以下步骤。

其中，第一基板和第二基板之间的相邻显示区域之间的封框胶具有预切割位置。
本实施例中在第二基板上的第二取向层同层且与预切割位置对应 的位置，同时在第一基板上的第一取向层同层且与预切割位置对应的位置处形成固化阻隔层。这样无论采用从第二基板侧还是第一基板侧进行紫外光照射实现封框胶的固化，由于固化阻隔层的存在均可以有效的保证进行封框胶切割的位置处的封框胶不被固化，进行切割工艺时都可以保证封框胶从切割位置断裂，实现了窄边框的设计。
根据本公开的实施例的显示面板的制作方法包括：形成第一基板，和与第一基板相对的第二基板，并在第一基板和第二基板之间尤其在周边区域设置封框胶将第一基板和第二基板密封。第一基板和第二基板上的相邻显示区域之间的封框胶具有预切割位置，然后在第一基板与封框胶之间且与预切割位置对应的位置，或者第二基板与封框胶之间且与预切割位置对应的位置处形成固化阻隔层。由于封框胶需要进行紫外光固化，固化之后的封框胶的硬度比较大，在进行显示屏切割工艺中不容易断裂，会出现断裂面不在相邻显示区域之间的封框胶的切割位置的情况。本公开中在相邻显示区域之间的封框胶的预切割位置上设置固化阻隔层，这样在进行紫外光照射固化的时候保证相邻显示区域之间的封框胶的预切割位置处不会被固化，使得该位置处的封框胶容易断裂，随后进行切割工艺的时可以保证封框胶在预切割位置处断裂，实现了显示屏的窄边框设计。根据本实施例的显示面板的制作方法，由于断裂位置准确，形成的显示屏可用，不会成为残次品，进而降低了生产成本，提高了显示屏的性能。
本公开的实施例提供一种显示装置，该显示装置包括图1～6对应的任一实施例中提供的显示面板。
根据本公开的实施例的显示装置包括：第一基板，和与第一基板相对的第二基板，第一基板和第二基板之间尤其在周边区域通过设置的封框胶，其将第一基板和第二基板密封，第一基板和第二基板之间的相邻显示区域之间的封框胶具有预切割位置。此外，第一基板上的与预切割位置对应的位置，或者第二基板上的与预切割位置对应的位置处设置有固化阻隔层。由于封框胶需要进行紫外光固化，固化之后的封框胶的硬度比较大，在进行显示屏切割工艺中不容易断裂，会出现断裂面不在共用的封框胶的切割位置的情况。本公开中在相邻显示区域之间的封框胶的预切割位置上设置固化阻隔层，这样在进行紫外光照射固化的时候保证相邻显示区域之 间的封框胶的预切割位置处不会被固化，使得该位置处的封框胶容易断裂，随后进行切割工艺时可以保证封框胶在预切割位置处断裂，实现了显示屏的窄边框设计。根据本实施例的显示装置，由于断裂位置准确，形成的显示屏可用，不会成为残次品，进而降低了生产成本，提高了显示屏的性能。
以上实施方式仅用于说明本公开，而并非对本公开的限制，有关技术领域的普通技术人员，在不脱离本公开的精神和范围的情况下，还可以做出各种变化和变型，因此所有等同的技术方案也属于本公开的范畴，本公开的专利保护范围应由权利要求限定。
