Description

封框胶、封框胶的光固化方法以及液晶显示装置 【技术领域】
本发明涉及显示技术领域,特别是涉及封框胶、封框胶的光固化方法以及液晶显示装置。
【背景技术】
液晶面板包括阵列(Array)基板和彩膜(CF)基板,另外Array基板和CF基板之间填充有液晶,并在LCD的周边涂布边框胶来粘合Array基板和CF基板,形成盒厚稳定的显示屏。通常LCD中使用的边框胶材料主要由亚克力树脂、环氧树脂、光引发剂、固化剂、填料和其他助剂组合而成,在UV照射和加热之后形成稳定的立体结构,从而具有足够粘结强度。
目前边框胶UV光照过程中,一般都是通过UV光照,光引发剂产生原子基团,从而诱发丙烯酸低聚物发生聚合反应,进而实现硬化。但是由于后续加热过程中反应不完全的光引发剂容易进入到液晶材料中,在液晶光照配向的过程中与液晶中的单体发生光聚合反应,从而导致液晶配向不良,或者溶解到液晶的光引发剂容易产生离子,导致液晶材料的电压保持率(VHR)下降。
因此,有必要提供一种封框胶、封框胶的光固化方法以及液晶显示装置,以解决现有技术所存在的问题。

在一实施方式中,所述感光性引发基团为羰基化合物基团。

S101、使用紫外光照射封框胶的材料,在感光性引发基团的作用下使丙烯酸单体中的双键产生自由基,并使所述自由基产生聚合反应。
例如,以感光性引发基团为羰基化合物基团为例,在现有的丙烯酸单体中引入了促进引发的羰基化合物基团,该羰基化合物基团在UV光照下发生光化学反应(NorrishⅡ反应),该羰基化合物基团通过夺取丙烯酸单体中碳碳双键中的氢键完成光解反应,从而使丙烯酸单体产生自由基,进而使自由基自发的发生聚合反应,该羰基化合物基团可以使丙烯酸单体实现与加入光引发剂的相似的光交联反应,从而完成封框胶的固化。

Figure PCTCN2018117096-appb-000010
其中R’代表烷基。
由于将感光性基团引入到丙烯酸单体中,实现其自发地发生聚合反应,也即通过感光性引发基团替代光引发剂,因此使得封框胶固化过程中不需要引入光引发剂,从而避免与液晶材料中的单体发生光聚合反应,提高了液晶分子的配向效果,此外还降低了溶解到液晶中的离子浓度,从而提高液晶的电压保持率(VHR)。
如图1所示,本发明还提供一种液晶显示装置,其包括阵列基板10和彩膜基板20,所述阵列基板10和所述彩膜基板20之间设置有封框胶25,彩膜基板20与阵列基板10相对设置,在所述彩膜基板20与阵列基板10之间还设置有液晶层。

综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
