显示模组及显示装置 技术领域
本申请涉及显示领域,具体涉及一种显示模组及显示装置。
背景技术
有机发光显示装置(OLED)已经广泛用于生活之中,如图1所示,有机发光显示装置包括有机发光显示面板本体10,为了实现有机发光显示装置的窄边框设计,通常将有机发光显示面板本体10划分为非弯折部FF1和弯折部FF2,通常弯折部FF2为下边框进行绑定或电性连接驱动芯片和电路板的部位,在有机发光显示面板本体10的非弯折部FF1的背侧需要设置多层的支撑层,例如在有机发光显示面板本体10的背侧依次设置BP1层(背板层,通常为聚酰亚胺或PET材质)1011、缓冲层(第一支撑层,通常为泡棉材料,Foam)1012、SUS层(第二支撑层,通常为不锈钢材料)1013,由于有机发光显示装置在制作过程中,需要先将缓冲层1012与SUS层1013贴合,再将缓冲层1012与SUS层1013的整体与显示面板本体10贴合,贴合过程需要利用SUS层1013进行抓取对位,因此缓冲层1012需要内缩设置,即BP1层1011和SUS层1013在靠近弯折部FF2的端部的长度大于缓冲层1012靠近弯折部FF2的端部的长度,以形成缺口133,在有机发光显示面板本体10的正侧设置有偏光片21,在弯折部FF2的正侧设置有保护胶层24,通常设置保护胶层24接触偏光片21的端部,用以防止水汽通过偏光片21的端部进入,提高可靠性,由于缓冲层1012内缩设置,显示面板本体10弯折后BP1层1011的支撑不够,应力较为集中,BP1层1011和弯折部位FF2会在缺口133上方塌陷(如图中虚线框分离形成塌陷部位52),导致塌陷部位的走线等膜层产生裂纹,从而降低了显示装置的可靠性。

本申请实施例提供一种显示模组及显示装置,显示模组包括:显示面板本体,包括弯折部和非弯折部;背板层,设于显示面板本体的非弯折部的背侧;第一支撑层,设于背板层远离显示面板本体的一侧;第二支撑层,设于第一支撑层远离显示面板本体的一侧;第一支撑层朝向弯折部的端部相对于背板层和第二支撑层朝向弯折部的端部内缩形成一缺口;以及,补强件;其中,补强件设置于背板层和第二支撑层之间,补强件至少部分设置于缺口内。
本申请实施例提供一种显示模组及显示装置。以下分别进行详细说明。需说明的是,以下实施例的描述顺序不作为对实施例优选顺序的限定。
实施例一、
请参阅图2,图2为本申请实施例提供的显示模组100的第一种截面示意图,显示模组100包括:显示面板本体10、背板层11、第一支撑层12、第二支撑层13和补强件18。显示面板本体10包括弯折部FF2和非弯折部FF1;背板层11设于显示面板本体10的非弯折部FF1的背侧;第一支撑层12设于背板层11远离显示面板本体10的一侧;第二支撑层13设于第一支撑层12远离显示面板本体10的一侧;第一支撑层12朝向弯折部FF2的端部相对于背板层11和第二支撑层13朝向弯折部FF2的端部内缩形成一缺口133;以及,补强件18;其中,补强件18设置于背板层11和第二支撑层13之间,补强件18至少部分设置于缺口133内。
具体的,显示面板本体10包括弯折部FF2和非弯折部FF1,以及与弯折部FF2连接的绑定部FF3,弯折部FF2设置于非弯折部FF1和绑定部FF3之间,弯折部FF2用以将绑定部FF3设置于非弯折部FF1的背侧。
具体的,显示面板本体10包括弯折部FF2和非弯折部FF1,背板层11、第一支撑层12、第二支撑层13和补强件18设置于显示面板本体10的非弯折部FF1的背侧,在显示模组100制作过程中,需要通过抓举第二支撑层13来进行定位,因此第一支撑层12需要在朝向弯折部FF2的一端进行内缩,即在朝向弯折部FF2的端部,背板层11和第二支撑层13相对于第一支撑层12向弯折部FF2突出形成缺口133,补强件至少部分设置于缺口133内。
在一些实施例中,补强件18的材质与背板层11或第二支撑层13的材质相同,补强件18的材质为金属或有机物。
具体的,补强件18的材质与背板层11或第二支撑层13相同,那么就没有引入新的材质,不对造成新材质引入降低可靠性的可能,在显示模组100制造时可以减小可靠性测试步骤。金属或有机物具有很强的韧性,受到外力作用时产生变形而不易折断,不会造成异物污染显示模组100。
在一些实施例中,背板层11为塑料或聚酰亚胺或PET(涤纶树脂,聚对苯二甲酸乙二醇酯),第一支撑层12为泡棉,第二支撑层13为不锈钢。
具体的,背板层11的材料可以为塑料或聚酰亚胺或PET,由于显示面板本体10太薄,背板层11用于提供给显示面板本体10以支撑作用;第一支撑层12的材料可以为泡棉,用于为显示面板本体10提供缓冲作用,例如缓冲外力的冲击;第二支撑层13的材料可以为不锈钢,为显示面板本体10提供支撑作用,使得显示面板本体10的非弯折部形成平面状态,便于显示图像。
在一些实施例中,背板层11朝向弯折部FF2的边缘与补强件18的边缘平齐,第二支撑层13朝向弯折部FF2的边缘与补强件18的边缘平齐。
具体的,背板层11、补强件18和第二支撑层13三者朝向弯折部FF2的边缘相互平齐,使得补强件18能够提供给弯折部位FF2的起始弯折处完全的支撑作用,同时不干涉影响到弯折部FF2的弯折形态,利于减小弯折部位的宽度,避免边框宽度增加。
在一些实施例中,补强件18的厚度与第一支撑层12的厚度相同。
具体的,补强件18的厚度与第一支撑层12的厚度相同,使得补强件18恰好契合缺口133的高度,补强件18可以提供最好的支撑作用。当然,在一些实施例中,在不影响补强件18的增强支撑作用的前提下,补强件18的厚度可以稍微大于或稍微小于第一支撑层12的厚度。
在一些实施例中,补强件18的边缘与第一支撑层12之间为非接触设计。
具体的,最理想的状态是补强件18的边缘与第一支撑层12之间恰好接触,然而,背板层11或第二支撑层13突出于第一支撑层12的长度会存在误差(或公差),或者说缺口133的长度会存在一定波动范围,同时补强件18的长度也有公差,因此通常设置补强件18的边缘与第一支撑层12之间为非接触设计,例如存在间隙部134,这样可以提升补强件18的贴合良率,有助于节省成本。
在一些实施例中,补强件18的边缘与第一支撑层12的边缘之间存在间隙部134。
在一些实施例中,间隙部134的宽度小于或等于100微米。
具体的,在一些实施例中,补强件18与第一支撑层12之间的间隙部134的宽度要小于或等于100微米,理想状况是补强件18与第一支撑层12之间的间隙部134的宽度为0,然而材料裁切以及贴合工艺等存在公差和误差,因此设置了间隙部134,较小的间隙部134的宽度,有助于提供足够的支撑力,同时有助于减小边框宽度。
需要说明的是,在一些实施例中,补强件18的宽度可以设定为200微米至500微米之间,补强件18既可以增加支撑力,又不会占据较大宽度,有利于窄边框设计。
显示面板本体10可以为有机发光显示面板的本体,例如显示面板本体10包括阵列基板、设于阵列基板上的发光器件,以及设于发光器件上的封装层,显示面板本体10的结构不限于此。
在本申请实施例中,设置补强件18,补强件至少部分设置于缺口133内,可以为显示面板本体10提供足够的支撑,避免了应力集中,防止了显示面板本体10在缺口133上方塌陷,防止了显示面板本体的走线等膜层产生裂纹,提升了显示面板模组和显示装置的可靠性。
实施例二、
本申请实施例与上述实施例相同或相似,不同之处在于补强件18与背板层11或第二支撑层13为一体化结构。
请参阅图3、图4,图3为本申请实施例提供的显示模组100的第二种截面示意图,图4为本申请实施例提供的显示模组100的第三种截面示意图。
具体的,如图3所示,补强件18为第二支撑层13延伸连接的整体。即补强件18与第二支撑层13为一体化结构,补强件18可与第二支撑层13通过一体蚀刻等方式形成。例如,补强件18可和第二支撑层13的材料均为SUS(不锈钢),可以在制作第二支撑层13时同时制作处补强件18。
具体的,如图4所示,补强件18为背板层11延伸连接的整体。即补强件18与背板层11为一体化结构,补强件18可与背板层11通过一体成膜形成。例如,补强件18和背板层11的材质均为塑料或聚酰亚胺(PI)或PET,在制作背板层11时,同时制作处补强件18。
本申请实施例,通过设置补强件18为背板层11或第二支撑层13延伸连接的整体,补强件18不需要单独制作,节省了补强件单独制作的工艺,同时补强件18不需要单独增加工艺设置在缺口133上,只要设置背板层11或第二支撑层13就同时设置了补强件18,具有简化制作工艺,节省材料的有益效果。
实施例三、
本申请实施例与上述实施例相同或相似,不同之处在于背板层11朝向弯折部FF2的边缘突出于补强件18的边缘。
请参阅图5,图5为本申请实施例提供的显示模组100的第四种截面示意图。
在本申请实施例中,第二支撑层13朝向弯折部FF2的边缘与补强件18的边缘平齐,背板层11朝向弯折部FF2的边缘突出于补强件18的边缘。
在本申请实施例中,补强件18和第二支撑层13二者朝向弯折部FF2的边缘相互平齐,使得补强件18提供完全的增强支撑作用,避免了应力集中。同时背板层11朝向弯折部FF2的边缘相对于补强件18突出一定长度,如图5中背板层11的突出部位61,可以不影响补强件18的增强支撑作用,同时,为背板层11、补强件18和第二支撑层13三者的贴合工艺提升良率,补强件18和第二支撑层13整体与背板层11贴合时会存在误差(或公差),如果背板层11朝向弯折部FF2的边缘突出于补强件18的边缘一定长度,那么可以很好的防止贴合后发生补强件18朝向弯折部FF2的边缘突出于背板层FF1朝向弯折部FF2的边缘的情况发生,从而提升了贴合良率。
实施例四、
本申请实施例与上述实施例相同或相似,不同之处在于:补强件18靠近弯折部FF2的一端的厚度小于补强件18远离弯折部FF1的一端的厚度。
请参阅图6,图6为本申请实施例提供的显示模组100的第五种截面示意图。
在本申请实施例中,补强件18靠近弯折部FF2的一端的厚度小于补强件18远离弯折部FF1的一端的厚度。
具体的,在弯折部FF2的边缘具有弯折的趋势,设置补强件18靠近弯折部FF2的一端的厚度小于补强件18远离弯折部FF1的一端的厚度,可以使得补强件18的形状契合弯折部FF2的边缘的弯折趋势,即使由于制程误差,例如补强件向弯折部FF2靠近偏离一些,由于补强件18靠近弯折部FF2的一端的厚度减小,也可以避免补强件18干涉影响弯折部FF2的弯折,避免边框宽度增加。
实施例五、
本申请实施例与上述实施例相同或相似,不同之处在于:本申请实施例还包括其他结构。
请参阅图7,图7为本申请实施例提供的显示模组100的第六种截面示意图。
显示模组100还包括:偏光片21、保护胶层24,偏光片21,设置于显示面板本体10的非弯折部FF1的正侧;保护胶层24,设置于显示面板本体10的弯折部FF2的正侧,且保护胶层24与偏光片21的端面接触;其中,第一支撑层12在背板层11上的正投影覆盖偏光片21和保护胶层24的接触部在背板层11上的正投影。
具体的,保护胶层24与偏光片21的端面接触,那么保护胶层24也保护了偏光片21的端面,防止水汽等从过偏光片21的端面进入偏光片21的内部,从而提升了显示模组100的可靠性。第一支撑层12在背板层11上的正投影覆盖偏光片21和保护胶层24的接触部在背板层11上的正投影,使得偏光片21和保护胶层24的接触部与显示面板本体10的非弯折部FF1的其他区域处于均一的膜层堆叠情况上,使得偏光片21和保护胶层24的接触部受到的应力与非弯折部FF2的其他部位受到的应力情况一样,从而更好的避免了保护胶层24与偏光片21的分离,避免水汽进入影响可靠性,从而提升了显示模组100的可靠性。
实施例六、
本申请实施例与上述实施例相同或相似,不同之处在于:还介绍了可以应用于上述实施例中的补强件18和第二支撑层13的结构。
请参阅图8、图9,图8为本申请实施例提供的补强件18和第二支撑层13截面示意图。图9为本申请实施例提供的补强件18和第二支撑层13作为整体贴合第一支撑层12后的截面示意图。
具体的,在本申请实施例中,详细介绍了补强件18为第二支撑层13延伸连接的整体的结构。即补强件18和第二支撑层13为相互连接的整体,补强件18可与第二支撑层13通过一体蚀刻等方式形成。
具体的,如图8所示,在来料时,补强件18为第二支撑层13延伸连接的整体的结构,补强件18和背板层11的整体结构的上下表面分别包括第一离型膜135和第二离型膜131,第一离型膜135和第二支撑层13之间设置有填充层132,填充层132与补强件18同层设置,填充层132的材料可以为塑料等,填充层132的作用是为第一离型膜135提供支撑,第一离型膜135和第二离型膜131起到抗异物抗刮伤等保护作用。
具体的,如图9所示,在补强件18和第二支撑层13作为整体贴合第一支撑层12时,去除第一离型膜135和填充层132,将第一支撑层12贴合于填充层132的部位,同时保留第一支撑层12的第三离型膜121。
