另一方面,本申请提供一种电子设备,包括如上所述的显示模组。
参考图1所示,本申请一实施方式提供一种电子设备100,电子设备100包括显示模组10和外壳20,显示模组10与外壳20相连,共同形成有安装空腔,以用于安装电子设备100的电池、电路板等电子元器件。显示模组10可用于显示信息并为用户提供交互界面。
显示模组10具有出光面10a,出光面10a包括平面区域P和曲面区域Q,曲面区域Q连接于平面区域P的边缘,且两者之间的交界线包括依次邻接的第一直边线L1、弧边线L2和第二直边线L3,第一直边线L1的延长线和第二直边线L3的延长线相交,曲面区域Q包括对应于弧边线L2的角部区域G。由于该角部区域G对应于显示模组10的相邻两条边的交界位置,因此,角部区域G所在位置的曲面既有绕平行于第一直边线L1的方向上的弯曲部分,同时,也有绕平行于第二直边线L3的方向上的弯曲部分,以及绕与第一直边线L1和第二直边线L3均垂直的方向上的弯曲部分。在一些实施方式中,该角部区域G所在位置的曲面为高斯球面。对于角部区域G所对应的曲面形状,在不做限定。
需要说明的是,上述仅是为了便于理解,将平面区域P和曲面区域Q交界位置的边线称为“交界线”,实际上,平面区域P和曲面区域Q可以没有明显的分界,仅是以曲面区域Q向平面区域P的弧度变化的轮廓进行划分,具体地,曲面区域Q的弧度平面区域P的弧度大,从而在两者接壤处可以采取前述的“交界线”进行划界,相应地,第一直边线L1、弧边线L2和第二直边线L3都是该交界线的一部分,也是平面区域P的边线的一部分,其中,弧边线L2为对应平面区域P的角落位置的边线。第一直边线L1和第二直边线L3可以为平面区域P垂直的两边。在一些实施方式中,电子设备100呈矩形块状,相应地,平面区域P的轮廓为四角呈弧形的矩形,此时,第一直边线L1和第二直边线L3分别对应于电子设备100的长边和短边。
结合图2所示,在一些实施方式中,显示模组10包括显示面板11和盖板12,显示面板11贴附在盖板12的背面,即,显示面板11贴附在盖板12的背向出光面10a的一侧。盖板12起到保护显示面板11的作用,盖板12具体可以是玻璃材质,也可以是塑料材质。对于盖板12的材质,在此不做限定,只要盖板12能够对显示面板11进行保护,并适应显示面板11所发出的光线的透过需要即可。
在一些实施方式中,如图2所示,盖板12作为显示模组10的最外层结构件,此时,显示模组10的出光面10a为盖板12的背向显示面板11的一侧表面。结合图3和图4所示,盖板12包括平面部12a和曲面部12b,显示面板11贴附于盖板12。平面部12a对应于平面区域P设置,确切的说,平面部12a的暴露于电子设备100并作为电子设备100的出光面10a的部分界定平面区域P。曲面部12b对应于曲面区域Q设置,确切的说,曲面部12b暴露于电子设备100并作为电子设备100的出光面10a的部分界定曲面区域Q。由此,平面部12a和曲面部12b的交界线可以认为是前述的平面区域P和曲面区域Q的交界线。
在一些实施方式中,平面部12a呈矩形,曲面部12b包括四个角部12c,四个角部12c分别对应于平面部12a的四角,曲面区域Q包括四个角部区域G,四个角部12c与四个角部区域G一一对应。
发明人发现,将显示面板11贴合至盖板12时,如图5所示,显示面板11对应平面部12a的位置可以保持平整贴合,而显示面板11对应于曲面部12b的位置,会受到挤压,容易出现褶皱Z,继而显示面板11存在凸凹不平,对显示的画面造成不良影响。特别的,显示面板11贴合至曲面部12b越多,褶皱Z越明显,对显示画面造成的不良影响越深,而且,显示面板11受力过大时,甚至会出现撕裂,导致无法正常显示。为此,在将显示面板11贴附至盖板12时,不得不尽可能少地将显示面板11的结构对应设置于曲面部12b设置,然而,这又会引起盖板12的曲面部12b被显示面板11覆盖过少,而留出更多未被显示面板11贴附的区域,继而造成屏占比下降,这也会影响显示效果。
发明人经过不断地深入探索和研究,发现可以通过对显示模组10的叠层结构进行改进,来使得改进后的显示模组10既不会引起屏占比的下降,同时,也可以很好解决褶皱Z问题,以有效提升显示效果。
具体地,结合图6和图7所示,显示面板11包括层叠设置的多层有机材料层11a,至少一层有机材料层11a在对应角部区域G的位置Q1的厚度小于在对应平面区域P的位置Q2的厚度,从而有机材料层11a在对应角部区域G的位置Q1相比对应平面区域P的位置Q2更容易变形,因此,显示面板11对应角部区域G的位置更容易进行弯曲,降低挤压力,以减少褶皱Z的出现几率。需要说明的是,在本申请实施方式中,作为薄片状结构,厚度指的是薄片状结构中的距离最小的两个面之间的距离。对于厚度一致的薄片状结构而言,厚度即为薄片状结构的任意位置的厚度。对于厚度存在局部薄,局部厚的薄片状结构而言,薄片状结构的某区域厚度指的是该区域的平均厚度。以有机材料层11a在对应角部区域G的位置Q1的厚度小于在对应平面区域P的位置Q2的厚度为例,由于有机材料层11a在对应平面区域P的位置不需要弯折,有机材料层11a在对应该平面区域P的部分结构的厚度一致。在一些实施方式中,有机材料层11a在对应角部区域G是通过开槽的方式减薄时,有机层材料层对应该角部区域G的位置Q2的厚度可以做成厚薄一致。在一些实施方式中,有机材料层11a没有明显的凹槽,确切的说,有机材料层11a虽然在对应角部区域G的位置Q1的厚度经过减薄设置,但有机材料层11a的整体表面平滑,使得有机材料层11a在对应角部区域G的位置Q1和对应平面区域P的位置Q2之间没有明显的分界而呈现平滑过渡,例如,有机材料层11a在对应角部区域G的厚度在远离弧边线L2的方向上逐渐减小,使得有机材料层11a在对应角部区域G的位置Q1较薄,从而有利于提升该部分的弯曲性能,减少出现褶皱Z的几率。该实施方式中,有机材料层11a在对应角部区域G的位置Q1的厚度可以不是均匀不变,而是在远离弧边线L2的方向上逐渐减小,这样,局部减薄的有机材料层11a在对应角部区域G的位置Q1的平均厚度小于其他部分的厚度,从而有机材料层11a在对应角部区域G的位置Q1能够适应性提升显示面板11对应角部区域G的弯曲性能,继而降低出现褶皱Z的几率,提升显示效果。
结合图8和图9所示,在一些实施方式中,通过对显示面板11中的有机材料层11a进行局部减薄,使得显示面板11对应角部区域G的厚度小于其他部分的厚度,降低显示面板11贴附至盖板12时对应角部区域G位置的弯曲应力,继而降低出现褶皱Z的几率,同时,弯曲应力的降低也有利于提升显示面板11与盖板12之间的贴附稳定性。需要说明的是,在本申请实施方式中,显示面板11对应角部区域G位置的弯曲应力指的是显示面板11贴附至盖板12的对应角部区域G位置的部分结构在沿弧边线L2延伸方向上受到的挤压力。可理解地,该挤压力越大,显示面板11受到沿弧边线L2延伸方向上的挤压越严重,也就越容易出 现褶皱Z,因此,本申请实施方式,通过降低显示面板11在对应角部区域G的弯曲应力,减少褶皱Z的出现几率。
需要说明的是,在朝显示面板11的边缘靠近的方向上,显示面板11的与曲面部12b对应的位置的厚度逐渐减小,使得该部分结构的厚度平稳减小,显示面板11的表面能够整体维持平滑过渡,有利于维持整体结构强度,以及方便与盖板12相贴合。
在一些实施方式中,显示面板11的对应平面区域P的位置的厚度为0.03mm至0.04mm,显示面板11的对应角部区域G的位置的厚度比显示面板11的对应平面区域P的位置的厚度小0.01mm,也即,显示面板11的对应角部区域G的位置减薄了0.01mm。在一些实施方式中,显示面板11的对应角部区域G的位置也可以减薄0.01mm以上,例如,如图9所示,显示面板11的对应角部区域G的位置的厚度为d1,显示面板11的对应平面区域P的位置的厚度为d2,d2比d1厚0.012mm、0.015mm、0.017mm或0.02mm。对于显示面板11的对应角部区域G的位置的减薄厚度(即d2减去d1),在此不做限定。
进一步地,结合图10所示,显示面板11的对应于曲面部12b的除角部12c的位置以外的部分也可以进行减薄设计,确切的说,显示面板11的对应于曲面部12b的除角部12c的位置以外的部分,与对应于平面部12a的位置相比,厚度更薄,从而更容易弯折,有效提高了贴合稳定性。而且,通过这种设置,相当于显示面板11的对应于曲面部12b的位置整个进行了减薄设置,即显示面板11的边缘部分(对应于曲面部12b)的厚度,比显示面板11的中部位置(对应于平面部12a)的厚度薄,这种结构下,减薄操作简便,只需绕显示面板11的需要减薄的有机材料层11a的周向进行同步减薄即可,无需刻意针对角落位置进行减薄。
需要说明的是,显示面板11的叠层不同,可以对不同的有机材料层11a进行局部减薄,使得有机材料层11a在对应角部区域G的位置Q1的厚度小于在对应平面区域P的位置Q2的厚度。
有机材料层11a的材质可以为聚酰亚胺或聚对苯二甲酸乙二醇酯。
具体地,显示面板11可以包括依次层叠设置的衬底基板、驱动电路层和像素层。在像素层中设置有用于显示的子像素,驱动电路层中设置有用于驱动各个子像素发光的像素驱动电路。
衬底基板可以作为前述的有机材料层11a,进行减薄设计。该实施方式中,衬底基板的材料可以为聚酰亚胺或聚对苯二甲酸乙二醇酯。
显示面板11包括平坦化层,平坦化层设置在驱动电路层和像素层之间。平坦化层用于为像素层的像素电极提供平坦化表面。在一些实施方式中,平坦化层可以作为前述的有机材料层11a,进行减薄设计。平坦化层的材料可以为聚酰亚胺或聚对苯二甲酸乙二醇酯。
结合图9和图10所示,在一些实施方式中,显示模组10包括支撑层13,支撑层13叠设于显示面板11的背向出光面10a的一侧,以利用支撑层13为显示面板11提供稳定支撑。
需要说明的是,在本申请实施方式中,叠设包括直接接触的贴附,也包括通过中间层来实现彼此层叠。
下面显示模组10的OLED叠层结构为例,对显示模组10做进一步说明。
结合图11所示,显示模组10包括依次层叠设置的支撑层13、显示面板11、偏光片14和光学胶层15。其中,支撑层13作为基材,能够对显示面板11形成良好的支撑。偏光片14用于阻止外界环境光对显示模组10的反射影响。光学胶层15用于与盖板12的背向出光面10a的一侧相连接。光学胶层15的材料可以采取透明光学胶,从而在粘接偏光片14与盖板 12的同时,也能够满足显示面板11发出的光线穿过盖板12以进行画面显示的需要。
结合图12所示,在一些实施方式中,支撑层13包括与角部区域G相对应的多个支撑部13a,多个支撑部13a互不层叠,从而利用多个支撑部13a起到分散贴合应力的效果。具体地,在显示模组10贴附至盖板12时,由于支撑层13中与角部区域G相对应的多个支撑部13a互不层叠,从而即使支撑层13因与盖板12贴附时,对应角部区域G的位置受到挤压,互不层叠的多个支撑部13a可以吸收挤压力,从而降低支撑层13出现局部褶皱Z的几率,继而维持显示面板11与盖板12贴附稳定性以及显示模组10的显示效果
在一些实施方式中,至少2个相邻设置的支撑部13a相互拼接接触。结合图13和图14所示,全部的支撑部13a依次拼接接触,从而实现对显示面板11的对应角部区域G的位置起到良好的支撑作用。
继续参阅图13和图14所示,相互拼接接触的2个支撑部13a之间的拼接处形成接缝线13b,接缝线13b在平面区域P所在平面的正投影线为直线且与弧边线L2相交。需要说明的是,在本申请实施方式中,若非限定延长线相交,两条线相交指的是该两条线存在交点,且交点同时位于该两条线上而非其延长线上。通俗的说,这些彼此相交的线指的是轮廓线,并非延长线。以接缝线13b在平面区域P所在平面的正投影线为直线且与弧边线L2相交为例,接缝线13b在平面区域P所在平面的正投影线与弧边线L2存在交点,且该交点位于该两条线上。
由于接缝线13b在平面区域P所在平面的正投影线为直线且与弧边线L2相交,因此,相邻支撑部13a在沿弧边线L2方向是彼此分离的,从而能够在受到沿弧边线L2方向的挤压力时,支撑部13a可以减弱该挤压力。由此,在显示模组10贴附至盖板12时,支撑层13的支撑部13a能够很好地在对应角部区域G的位置消除挤压力,以降低出现褶皱Z的几率,同时,这些支撑部13a可以为显示面板11的对应角部区域G的位置提供稳定支撑,使得显示模组10与盖板12的整体贴附效果好,以维持良好显示效果。
进一步地,接缝线13b在平面区域P所在平面的正投影线与弧边线L2垂直。需要说明的是,在一些实施方式中,只有部分相邻的支撑部13a因拼接接触而形成接缝线13b,在接缝线13b为多条时,可以是全部的接缝线13b与弧边线L2垂直,也可以只有其中若干条接缝线13b与弧边线L2垂直。
将接缝线13b相对弧边线L2垂直设置,能够使得支撑部13a之间在沿弧边线L2延伸的方向上,能够更好的消除弯曲应力,从而降低出现褶皱Z的几率,使得支撑层13对应角部区域G的位置,这些支撑部13a可以更好地贴合角部区域G的弯曲形状,以对显示面板11进行稳定支撑。
在一些实施方式中,接缝线13b不限于与弧边线L2垂直。例如,接缝线13b在平面区域P所在平面的正投影线与弧边线L2呈90°±30°夹角,确切的说,接缝线13b在平面区域P所在平面的正投影线与弧边线L2之间的夹角可以为60°至120°之间的任意角度,具体可以为60°、69°、75°、88°、100°、110°或120°,在此不做限定。
需要说明的是,对于相邻设置的支撑部13a而言,支撑部13a之间可以是拼接接触,也可以是间隔设置,只要支撑部13a之间互不层叠,就可以在消除对应于角部区域G位置的弯曲应力。
具体地,结合图15和图16所示,至少2个相邻设置的支撑部13a间隔设置,两者之间的间隙形成有隔槽13c,隔槽13c由平面区域P延伸至角部区域G的远离弧边线L2的一侧。
隔槽13c为条形槽,条形槽的长度方向所在线在平面区域P所在平面的正投影线与弧边线L2相交,从而相邻支撑部13a在沿弧边线L2方向经过条形槽分隔,因此,在受到沿弧边线L2方向的挤压力时,支撑部13a可以减弱该挤压力。由此,在显示模组10贴附至盖板12时,支撑层13的支撑部13a能够很好地在对应角部区域G的位置消除挤压力,以降低出现褶皱Z的几率,同时,这些支撑部13a可以为显示面板11的对应角部区域G的位置提供稳定支撑,使得显示模组10与盖板12的整体贴附效果好,以维持良好显示效果。
继续参阅15和图16所示,条形槽的长度方向所在线在平面区域P所在平面的正投影线与弧边线L2之间的夹角的取值范围为60°至120°。在该角度取值范围下,位于条形槽两侧的支撑部13a之间可以在沿弧边线L2方向保持良好的间隔,从而消除沿弧边方向的挤压力,降低出现褶皱Z的几率,以维持对显示面板11的良好支撑,从而使得显示面板11具有良好显示效果。在一些实施方式中,条形槽的长度方向所在线在平面区域P所在平面的正投影线与弧边线L2之间的夹角可以为60°、69°、75°、88°、100°、110°或120°,在此不做限定。
进一步地,条形槽的长度方向所在线在平面区域P所在平面的正投影线与弧边线L2相垂直,从而条形槽的两侧的支撑部13a在沿弧边线L2方向具有足够大的形变空间,以更好的消除在沿弧边线L2方向的挤压力。
在一些实施方式中,隔槽13c的槽宽为0.05mm至1.0mm,比如隔槽13c的槽宽为0.05mm、0.06mm、0.07mm、0.08mm、0.09mm或1.0mm。隔槽13c的宽度控制在0.05mm至1.0mm,即不会因为隔槽13c的宽度过大,导致支撑部13a对显示面板11对应角部区域G的支撑力下降过多,显示面板11对应角部区域G无法获得足够支撑力,容易出现塌陷,造成显示不良。也避免隔槽13c的宽度过小,多个支撑部13a可能出现彼此层叠的情况,导致对显示面板11的支撑平稳性下降。
需要说明的是,两相邻的支撑部13a之间无论是采取拼接接触的方式,在两者之间形成接缝线13b,还是采取间隔设置的方式,在两者之间形成条形槽,都可以很好地利用多个支撑部13a互不层叠,并提供沿弧边线L2方向的变形空间,从而效果沿弧边线L2方向的挤压力,降低出现褶皱Z的几率。对于支撑部13a的数量,以及多个支撑部13a的形状,在此不做限定。例如,在一些实施方式中,支撑部13a为呈Z形或S形的杆状结构,数量为5至10个。在另一些实施方式中,支撑部13a为扇形的面状结构。在一些实施方式中,支撑部13a还可以是其他形状,例如,三角形或梯形,在此不做限定。
支撑部13a可以是在支撑层13的对应角部区域G的位置通过激光切割或刻蚀的方式形成。在一些实施方式中,支撑部13a也可以是通过注塑一体成型于支撑层13。
在一些实施方式中,支撑层13的材质为聚对苯二甲酸乙二醇酯,以利于在支撑层13对应角部区域G的位置形成支撑部13a。
支撑层13的厚度大于或等于60um,以维持支撑层13对显示面板11的支撑效果。
结合图17所示,显示模组10包括散热层16,散热层16叠设于支撑层13的背向显示面板11的一侧,以对显示模组10进行散热和缓冲。散热层16的厚度大于或等于0.16mm,以便在利用散热层16进行散热的同时,具有足够厚度来提升缓冲性能。在一些实施方式中,散热层16为多层复合结构,例如,散热层16包括依次层叠设置的石墨层、泡棉层和铜箔层,由此,既可以利用石墨层和铜箔层提升其导热性能,以更好的对显示模组10进行散热,同时,利用泡棉层发挥缓冲作用,以提升显示模组10的抗摔性能。
结合图18和图19所示,散热层16设有切口16a,切口16a对应于角部区域G,从而减少散热层16对应于角部区域G的应力,显示模组10整体容易贴附至盖板12,而不会在角部区域G出现褶皱Z,以维持良好的显示效果。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对申请专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本申请构思的前提下,还可以做出若干变形和改进,这些都属于本申请的保护范围。因此,本申请专利的保护范围应以所附权利要求为准。
