Description

薄膜晶体管液晶显示器 (Thin Film Transistor Liquid Crystal Display,简称 TFT-LCD) 因其功耗低、 制造成本低和无辐射等特点, 近年来得到了广泛应 用。 TFTiCD用的液晶显示面板主要包括对盒设置的彩膜基板和阵列基板、 填充于彩膜基板和阵列基板之间的液晶。
通常, 液晶分子是在彩膜基板和阵列基板进行对盒之前, 通过液晶滴下 技术 (One Drop Fill, 简称 ODF) 将液晶滴注在彩膜基板或阵列基板上, 之 后再将彩膜基板和阵列基板进行对盒, 以实现液晶的填充。
发明人在实现本发明的过程中发现, 在彩膜基板和阵列基板对盒之前, 液晶分子通常是滴注在彩膜基板或阵列基板的显示区域的中心部分, 并由显 示区域向四周逐步扩散。 若此时液晶接触到显示区域外的外围区域上的未完 全固化的封框胶, 封框胶中的小分子和极性基团可能进入到液晶中, 污染液 晶, 导致 TFTiCD发生残像, 影响用户的使用体验度。
本发明所要解决的技术问题在于提供一种液晶面板及显示装置, 能够减 缓液晶的流速, 降低液晶接蝕到未完全固化的封框胶的可能性。
为解决上述技术问题, 本发明采用如下技术方案:
本发明的第一方面提供了一种液晶面板, 包括相对设置的第一基板、 第 二基板、 以及位于所述第一基板和所述第二基板的外围区域的封框胶, 所述 第一基板上设置有紧靠所述封框胶的内侧壁的第一阻隔层。
所述第二基板上设置有至少一个位于所述封框胶内侧的第二阻隔层, 所 述第二阻隔层与所述封框胶之间具有一定间隔, 所述第二阻隔层的厚度小于 所述第一阻隔层的厚度。 所述第二阻隔层的高度小于第一基板和第二基板对盒后的距离。
所述第一基板上还设置有至少一个位于所述封框胶内侧的第三阻隔层, 所述第三阻隔层与所述封框胶之间具有一定间隔, 所述第三阻隔层的厚度小 于所述第一阻隔层的厚度。
所述第三阻隔层的高度小于第一基板和第二基板对盒后的距离。
所述第一阻隔层的远离所述第一基板的一面具有多个凹槽。
所述凹槽的深度为第一阻隔层的高度的 1/5至 1/3。
所述第一阻隔层的厚度为 50-1000微米, 所述第二阻隔层的厚度为 1 50 微米。
所述第一阻隔层和 /或所述第二阻隔层为矩形或圆角矩形。
所述第二阻隔层所述第二阻隔层的转角处设置有开口。
在本实施例的技术方案中, 第一阻隔层紧靠所述封框胶的内侧壁, 即第 一阻隔层的一面与封框胶的内侧壁接蝕, 使得封框胶仅有一小部分可能接触 到液晶, 大大降低了液晶接触到未完全固化的封框胶的可能性。 从而减小残 像发生的可能性, 提高用户的使用体验。
本发明的第二方面提供了一种显示装置, 包括上述的液晶面板。
为了更清楚地说明本发明实施例或现有技术中的技术方案, 下面将对实 施例描述中所需要使 ^的 ^图作筒单地介绍, 显而易见地, 下面描述中的附 图仅仅是本发明的一些实施例, 对于本领域普通技术人员来讲, 在不付出创 造性劳动的前提下, 还可以根据这些 Pf†图获得其他的 Pf†图。

下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行 清楚、 完整地描述, 显然, 所描述的实施例是本发明一部分实施例, 而不是 全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有做出创 造性劳动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。
本发明实施例提供一种液晶面板, 如图 1和图 2所示, 包括相对设置的 第一基板 I、第二基板 2、 以及位于所述第一基板 1和所述第二基板 2的外围 区域的封框胶 3, 所述第一基板 1 上设置有紧靠所述封框胶 3的内侧壁的第 一阻隔层 4。
在本发明实施例中, 第一阻隔层 4紧靠所述封框胶 3的内侧壁, 即第一 阻隔层 4的一面与封框胶 3的内侧壁接蝕, 使得封框胶 3仅有一小部分可能 接触到液晶, 大大降低了液晶接触到未完全固化的封框胶 3的可能性。 从而 减小残像发生的可能性, 提高了 ^户的使用体验。
迸一歩的, 如图 3和图 4所示, 所述第二基板 2还包括至少一个位于所 述封框胶 3内侧的第二阻隔层 5, 所述第二阻隔层 5与所述封框胶 3之间具 有一定间隔, 其中, 所述第二阻隔层 5的厚度小于所述第一阻隔层 4的厚度。 另外, 第二阻隔层 5比第一阻隔层 4更靠封框胶 3的内侧。
厚度较小的第二阻隔层 5与第一基板 1和第二基板 2形成液晶的折线形 通道, 可降低液晶在第一基板 I 和第二基板 2 之间的扩散的速度且不影响 TFT-LCD的窄边框设计。
同时, 厚度比第二阻隔层 5大的第一阻隔层 4紧靠封框胶 3, 使得封框 胶 3仅有很小的一部分区域可能接触到液晶, 第一阻隔层 4和第二阻隔层 5 的配合能更好地降低液晶接蝕到未完全固化的封框胶 3的可能性。 其中,第二阻隔层 5和所述封框胶 3之间的间隔可以根据实际情况设置, 并且, 同一个第二阻隔层 5各处与封框胶 3之间的间隔可不一样, 但要防止 第二阻隔层 5与第一阻隔层 4接触。
需要说明的是, 第一阻隔层 4的厚度应较大, 否则封框胶 3可能在第一 基板 1 和第二基板 2对盒时受到挤压, 蔓延过厚度不够大的第一阻隔层 4, 导致第一阻隔层 4失效。
在本实施例中, 由于第一阻隔层 4的厚度较大, 因而仅设置一层; 而第 二基板上的第二阻隔层 5的厚度较小, 优选的可以设置 3-5层, 这样既不影 响由该基板组成的 TFTiCD的窄边框化,同时还可起到很好的减缓液晶的扩 散速度的作用。
为降低液晶在第一基板 i和第二基板 2之间的扩散速度, 所述第一基板 1上还可以设置至少一个位于所述封框胶 3内侧的第 阻隔层 6,与第二阻隔 层 5类似, 所述第 ΞΞ阻隔层 6的厚度小于所述第一阻隔层 4的厚度。 具体的, 第一基板 1上所设置的第≡阻隔层 6也可优选为 3 5层, 设置于第一基板 1 上的第 阻隔层 6可与设置于第二基板 2上的第二阻隔层 5相互平行交叉设 置, 如图 5和图 6所示。 实践证明, 该液晶面板的残像消失的时间为 3- 5分 钟, 相对于其他液晶面板, 残像消失的时间至少缩短了 30%。
同时, 如图 4或图 6所示, 所述第一阻隔层 4的高度、 所述第二阻隔层 5的高度和所述第≡阻隔层 6的高度小于第一基板 1和第二基板 2对盒后的 距离, 所述第一阻隔层 4的高度、 所述第二阻隔层 5的高度和所述第三阻隔 层 6的高度三者中任意两者之和大于第一基板 1和第二基板 2对盒后的距离, 使得第一阻隔层 4、 第三阻隔层 6和第二基板 2之间、 第二阻隔层 5和第一 基板 1、 第二基板 2之间都具有一定的缝隙, 有利于扩散到外围区域的液晶 回流到液晶面板中间的显示区域(图 1、 3或 5的虚线框) 内。 如果液晶面板 在受到外界条件的影响下, 如受到高温、 拍打或挤压等作用时, 液晶面板可 能发生形变, 显示区域内的液晶可遥过缝隙扩散到外围区域中; 当影响液晶 面板发生形变的外界条件消失后, 如温度降至常温、 拍打或挤压等外力消失 寸, 外围区域留有的部分液晶又可遥过这些缝隙回流到显示区域中, 使得液 晶面板的液晶显示区域中的液晶总量保持不变, 从而有利于提高液晶面板的 产品品质和显示特性的稳定。
具体的, 用于形成第一阻隔层 4和 /或第二阻隔层 5的材料可以包括: 透 明的或不透明的树脂材料或其他非金属材料。一般的, 若该基板为彩膜基板, 该第一阻隔层 4和 /或第二阻隔层 5可以与基板上的隔垫物、 黑矩阵甚至彩色 树脂一体成型; 类似的, 若该基板为阵列基板, 该第一阻隔层 4和 /或第二阻 隔层 5可以与基板上的隔垫物一体成型。
进一步的, 如图 7所示, 所述第一阻隔层 4远离所述第一基板 1的一面 可具有多个凹槽 7。 当液晶扩散至第一阻隔层 4时, 首先迸入第一阻隔层 4 的多个凹槽 7, 填满凹槽 7后才会继续向封框胶 3方向扩散, 延长了液晶接 触到封框胶 3的^间,降低了液晶接触到未完全非固化的封框胶 3的可能性。 其中, 该凹槽 7的形状优选为圆形, 矩形、 菱形、 不规则形状等亦可, 深度 可根据实际情况进行设置, 优选的, 如图 8所示, 所述凹槽 7的深度为第一 阻隔层 4的高度的 1/5至 1/3。 另外, 在图 7及 8中表示了在第一阻隔层 4上 设置多个凹槽 7的情况, 但是也可以设置一个在第一阻隔层 4范围内连续的 凹槽 7 , 这样能够进一步延长液晶接触到封框胶 3的时间。
在本实施例中, 第一阻隔层 4和第二阻隔层 5的厚度都可根据实际情况 任意设置, 但要保证第一阻隔层 4的厚度大于第二阻隔层 5的厚度。 优选的 所述第一阻隔层 4的厚度为 50-1000微米, 所述第二阻隔层 5的厚度为 1-50 微米, 例如, 第一阻隔层 4的厚度为 300微米左右, 第二阻隔层 5的厚度为
I D 1UZx:4
类似的, 如图 1、 3或 5所示, 所述第一阻隔层 4和 /或所述第二阻隔层 5 为矩形, 由于封框胶 3通常为圆角矩形, 为了提高第一阻隔层 4和封框胶 3 之间的配合效果, 第一阻隔层 4优选与封框胶 3相应的圆角矩形, 通常, 第 一阻隔层 4的形状与封框胶 3的一致, 以提高第一阻隔层 4和封框胶 3的配 口从木
相应的, 第二阻隔层 5也可为矩形或圆角矩形。 此外, 第二阻隔层 5也 可为其他形状, 例如菱形、 平行四边形等。
通常, 液晶是从基板的中心开始向四周均匀扩散, 若第二阻隔层 5为矩 形或圆角矩形, 由于第二阻隔层 5的转角处相对于第二阻隔层 5的其余部分 而言, 距离液晶扩散的中心最远, 所以液晶到达第二阻隔层 5的圆角处所需 的时间最长, 在该处液晶接蝕上未完全固化的封框胶 3的概率很小, 所以可 在所述第二阻隔层 5设置有开口, 尤其是在圆角处设置开口, 如图 9所示, 该开口有利于因液晶面板受到外力而流到第二阻隔层 5外的液晶回流, 保证 液晶面板的显示效果。
本发明实施例还提供了一种显示装置,该显示装置包括上述的液晶面板。 具体的, 该显示装置可以为、 液晶面板、 电子纸、 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。
以上所述, 仅为本发明的具体实施方式, 但本发明的保护范围并不局限 于此, 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内, 可轻易 想到变化或替换, 都应涵盖在本发明的保护范围之内。 因此, 本发明的保护 范围应以所述权利要求的保护范围为准。
