Description

一种显示用基板及显示装置 技术领域
本公开的实施例涉及一种显示用基板及显示装置。
背景技术
有机电致发光二极管(OLED，Organic Light-Emitting Diode)是一种全固态、主动发光、高亮度、高对比度、超薄超轻、低功耗、无视角限制、工作温度范围广等特性，被认为是下一代平面显示器的主导技术。
OLED器件的寿命是目前困扰OLED产业发展的关键问题。通过大量的试验与分析，发现认为OLED失效的主要原因为OLED器件的微型电解池失效模型。具体来讲，由于OLED器件属于直流电流驱动型的器件，当OLED处于工作状态时，如果器件内部有水汽的话，在器件内部就会形成一个微型的电解池，发生电化学反应，产生的反应气体会使金属阴极与有机功能层分离，导致器件失效。而且，惯常的OLED器件所用的金属阴极一般由铝制成，而铝是比较活泼的金属，易与渗透进来的水汽发生反应，形成电阻值很大的介质层，这相当于在器件内部串联了一个大电阻，这也会影响器件的亮度。另外，水汽和氧气还会与有机材料发生化学反应，这些反应也会引起器件的失效。因此，研究有机发光器件的封装对于提高器件的效率，延长器件的寿命具有重要的意义。
目前用于OLED封装的一种方法是采用不同类型的环氧树脂和/或无机材料通过紫外光固化后形成密封的胶层。尽管这种密封方法通常能提供良好的机械强度，但是在很多环境下，这些密封未能提供足够的对水汽的阻隔能力。
发明内容

本公开的至少一个实施例提供了一种显示用基板，包括环形的封装区域 以及位于所述封装区域内侧的显示区域，所述封装区域包括环形的粘附区以及位于所述粘附区内侧和/或所述粘附区外侧的凹槽区，所述凹槽区形成有凹槽结构，且所述凹槽结构内设置有吸水材料。
本公开的至少一个实施例提供了一种显示装置，包括对盒的第一基板和第二基板，所述第一基板和/或所述第二基板为根据本公开实施例的任一所述的显示用基板。
根据本公开的实施例提供的显示用基板及显示装置，显示用基板包括环形的封装区域以及位于封装区域内侧的显示区域，封装区域包括环形的粘附区以及位于粘附区边缘内侧和/或粘附区边缘外侧的凹槽区，凹槽区形成有凹槽结构，且所述凹槽结构内设置有吸水材料。采用紫外光照射粘附区，固化树脂层进行封装时，凹槽结构可以存储树脂层受紫外光照射时产生的液体，且凹槽结构内的吸水材料可以将其吸收。显示用基板对盒后，水汽可以被凹槽结构内的吸水材料吸收，从而改善对盒后显示装置隔离水汽的效果，延长显示装置的寿命。

如图6所示的显示装置，对盒的第一基板20和第二基板30中，第一基板20包括环形的封装区域11以及位于封装区域11内侧的显示区域13，以第一基板20为图2所示的显示用基板为例，封装区域11包括环形的粘附区111以及位于粘附区111内侧和粘附区111外侧的凹槽区112，粘附区形成有封框胶40，凹槽区112形成有凹槽结构12，且凹槽结构12内设置有吸水材料。当然，第一基板20还可以是如图3、图4所示的显示用基板，也可以是第二基板为图2-图4任一所示的显示用基板。
如图7所示的显示装置，对盒的第一基板20和第二基板30中，第一基板20和第二基板30均包括环形的封装区域11以及位于封装区域11内侧的显示区域13，第一基板20和第二基板30均以图2所示的显示用基板为例，封装区域11包括环形的粘附区111以及位于粘附区111边缘内侧和粘附区111边缘外侧的凹槽区112，粘附区形成有封框胶40，凹槽区112形成有凹槽结构12，且凹槽结构12内设置有吸水材料。当然，第一基板20和第二基板30还可以是如图2-图4所示的任一显示用基板。
需要说明的是，图6、图7所示的显示装置，在对盒时，首先在第一基板或第二基板的粘附区位置处涂覆一层树脂层，第一基板和第二基板通过粘附区的树脂层进行粘附，再通过紫外光照射，使得树脂层硬化，以完成OLED显示装置的封装。树脂在紫外光照射的情况下，会因受热产生流动的液体，则凹槽结构中吸水物质可以将液体吸收，以避免其流动带来其他损害，例如液体流入显示区域，造成显示区域的显示器件短路等。
在本公开的一个实施例中，显示装置为OLED显示装置，第一基板为阵列基板，第二基板为封装基板。由于水汽是影响OLED器件寿命的主要因素，因此，通过根据本公开实施例的显示用基板，可以提高OLED显示装置隔离水汽的功效，以进一步提高OLED显示装置的寿命。
以上所述仅是本公开的示范性实施方式，而非用于限制本公开的保护范围，本公开的保护范围由所附的权利要求确定。
本公开要求于2015年5月26日递交的中国专利申请No.201510275555.1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公开的一部分。
