本发明提供一种柔性OLED显示器件剥离方法,如图1、图2所示,该
方法包括下述步骤:
在承载基板1的一面涂布薄膜层2,其中,承载基板1为玻璃板、亚克力板、表面粗糙的金属板中的一种,薄膜层2的材料为萘、五氯化磷、胺类化合物、聚醇类化合物、石蜡中的至少一种。
在薄膜层2上形成柔性衬底层3。
在柔性衬底层3上形成低温多晶硅层4。
在低温多晶硅层4上形成发光层5。
在发光层5上形成封装层6。
对薄膜层2进行加热,直至柔性衬底层3与承载基板1剥离,得到柔性OLED显示器件。
萘、五氯化磷为易升华材料,胺类化合物、聚醇类化合物、石蜡为低熔点材料,只需要对其进行稍微加热,一般而言,加热的温度在30-200℃之间,不需要太高的温度,就可以让这些材料发生升华或者熔化,使得承载基板1与柔性衬底层3之间剥离,进行剥离的操作比较简单方便,也不需要激光设备,因而成本比较低。
需要说明的是,对薄膜层2加热,不局限于对薄膜层2直接加热,还可以在承载基板1的下方对薄膜层2进行加热。对薄膜层2进行加热的方式为镭射加热、烘箱加热、红外加热、电磁加热中的一种。
由于玻璃板表面有-OH等基团,萘、五氯化磷、胺类化合物、聚醇类化合物、石蜡等材料与玻璃板1之间可以通过化学键等直接结合,就可以粘接在玻璃板上,不需要额外的粘接层。此外,萘、五氯化磷、胺类化合物、聚醇类化合物、石蜡等材料与亚克力板之间也可以通过化学键结合,粘接在亚克力板上。或者,承载基板1为表面粗糙的金属板,具体而言,承载基板1上用于涂布有薄膜层的一面为粗糙,萘、五氯化磷、胺类化合物、聚醇类化合物、石蜡等材料就可以比较好的粘接在金属板上。
进一步地,封装层包含有SixOy和/或SiN,其中,x≥1,y≥1。SixOy例如可以是SiO、Si2O3、Si3O4,SixOy或者SiN膜对氧气和水蒸气具有良好的阻隔作用。其中,封装层6还可以包括有树脂薄膜。
进一步地,胺类化合物为芳香胺化合物或者丙烯酰胺中的至少一种。
进一步地,聚醇类化合物为聚乙二醇。
进一步地,薄膜层2的厚度为纳米级或者微米级。薄膜层2作为牺牲层,初始为固态,粘接在承载基板1上,将柔性衬底层3与承载基板1隔离开,薄膜层2的厚度为纳米级或者微米级,在达到熔点温度或者升华的温度后,能够快速的熔化或者升华,使得柔性衬底层3与承载基板1之间能够快速剥离。
进一步地,柔性衬底层3为是聚乙烯(PE)、聚丙烯(PP)、聚苯乙烯(PS)、聚对苯二甲酸乙二醇酯(PET)、聚对萘二甲酸乙二醇酯(PEN)、聚酰亚胺(PI)中至少一种材料制成的透明膜。优选地,柔性衬底层3为聚酰亚胺(PI)材料制成的透明薄膜。
进一步地,发光层5包括有机EL层。
进一步地,当薄膜层2为萘、五氯化磷中的至少一种材料制成时,在对薄膜层2进行加热时,还进行真空辅助处理。
其中,萘和五氯化磷均为易升华材料,在加热达到相应的升华温度时,会发生升华,而在对由萘和五氯化磷制成的薄膜层2进行加热时,进行真空辅助处理,可以加快其升华的速度。
进一步地,当承载基板1为玻璃板时,在玻璃板上用于涂布薄膜层2的一面进行等离子处理,增加其表面的羟基数量及粗糙度,以增加薄膜层2或蒸镀的SiO或SiN与玻璃板之间的粘接力。
本发明还提供一种柔性OLED显示器件,该柔性OLED显示器件由上述的柔性OLED显示器件剥离方法制成。
综上所述,本发明提供的柔性OLED显示器件剥离方法,在玻璃板、亚克力板或者表面粗糙的金属板构成的承载基板1,其表面涂布一层由萘、五氯化磷、胺类化合物、聚醇类化合物、石蜡中的至少一种材料制成的薄膜层2,而这些材料又可以与承载基板1表面的基团通过化学键直接结合形成粘接力,使得薄膜层2与承载基板1之间能够粘接在一起,再在薄膜层2上依次形成柔性衬底层3、低温多晶硅层4、发光层5、封装层6,构成柔性OLED显示器件,最后对薄膜层2进行微加热,就可以使薄膜层2熔化或者升华,将柔性OLED显示器件与承载基板1剥离。
本发明使用的薄膜层2本身熔点低或者易升华,给薄膜层2加热达到相应的熔点温度或者升华温度,使其熔化或者升华,就可以让柔性OLED显示器件与承载基板1之间分离,不会出现显示器件的柔性衬底层3与承载基板1之间出现难以剥离的情形,也不会出现拉扯导致OLED显示器件中的膜层(例如EL层)破裂,提高了OLED显示器件的剥离过程良率。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明,不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干简单推演或替换,都应当视为属于本发明的保护范围。
