具体实施方式
正如背景技术所述,现有技术中可折叠或者可弯曲显示屏的折叠形式单一。申请人研究发现,出现这种问题的原因在于现有技术中的可折叠或者可弯曲显示屏为多个显示屏进行拼接而成,要想获得可以多次折叠的显示屏,需要将多个显示单元进行拼接而成,从而使得折叠显示屏的折叠形式较为单一。
基于此,本申请提供了一种柔性显示面板,通过使用一个完整的柔性显示屏,而柔性显示屏通过至少一个折线展开或者折叠,既能够满足折叠的需求,丰富了柔性显示屏的可折叠形式,同时由于是同一个显示屏进行多次折叠,被折线划分的多个显示单元之间不需要额外的信号连接器,避免了多次折叠后因为信号传输不良、串扰等问题而造成的显示效果不佳的问题,从而提高了柔性显示面板的显示效果。
具体的,本申请提供的柔性显示面板,包括柔性显示屏以及至少一个延伸方向为第一方向的第一折线,其中,柔性显示屏的显示面板第一折线划分 为多个显示单元,多个显示单元通过第一折线折叠或展开。
图1所示为本申请一实施例提供的一种柔性显示面板的结构示意图如图1所示。柔性显示面板包括柔性显示屏1以及延伸方向为第一方向的至少一个第一折线21,其中,柔性显示屏1的显示面板由第一折线21划分为多个显示单元3,多个显示单元3通过第一折线21折叠或者展开,本申请实施例提供的柔性显示面板中,同一个柔性显示屏1通过多个第一折线折叠或者展开,且同一个柔性显示屏1通过多个第一折线既可以实现内折也可以实现外折,同时由于是同一个显示屏进行多次折叠,被第一折线划分的多个显示单元3之间不需要额外的信号连接器,避免了多次折叠后因为信号传输不良、串扰等问题而造成的显示效果不佳的问题,从而提高了柔性显示面板的显示效果。
至于柔性显示面板包括的第一折线21的个数,可以根据实际的应用场景来选择,例如,柔性显示面板可以包括两个第一折线21,如图1所示,柔性显示屏1的显示面板由两个第一折线21划分为三个显示单元3,柔性显示面板可以通过两个第一折线21完成两次折叠,从而使得柔性显示面板体积小,便于携带。因此本申请对于柔性显示面板包括的第一折线21的个数不作限定。
可选的,柔性显示面板进一步包括延伸方向为第二方向的至少一个第二折线22,第一方向与第二方向互相垂直,其中柔性显示屏1的显示面板由第一折线21以及第二折线22划分为多个显示单元3,多个显示单元3通过第一折线21以及第二折线22折叠或者展开,如图2所示。本申请实施例提供的柔性显示面板,同一个柔性显示屏1的显示面上的多个显示单元3可以通过至少两个互相垂直的折线实现至少两次折叠,当柔性显示面板进行多次折叠后可以使得多个显示单元3重叠在一起,便于携带,当多个显示单元3被完全展开后,又增大了显示面板的显示屏幕的面积,提高了用户的体验,同时由于是同一个显示屏进行多次折叠,被折线划分的多个显示单元3之间 不需要额外的信号连接器,避免了多次折叠后因为信号传输不良、串扰等问题而造成的显示效果不佳的问题,从而提高了柔性显示面板的显示效果。
可选的,柔性显示屏1的显示面板由第一折线21与第二折线22平均划分为多个显示单元3,即多个显示单元3的形状、面积、大小均相同,当柔性显示面板通过第一折线21或者第二折线22进行折叠后,折叠后的显示单元3可以互相完全重叠,更加了缩小了柔性显示面板的体积。
至于柔性显示面板包括的第一折线21以及第二折线22的个数,可以根据实际的应用场景来选择,例如,柔性显示面板可以包括一个第一折线21以及一个第二折线22,如图2所示,柔性显示屏1的显示面板由第一折线21以及第二折线22划分为四个显示单元3,其中当柔性显示面板通过第二折线22外折叠后,柔性显示面板中则只有两个显示单元3能够正对着使用者,如图3所示。当将通过第二折线22折叠后的柔性显示面板再通过第一折线21外折后,柔性显示面板中则只有一个显示单元3正对着使用者。如图4所示。
如前述所述,当柔性显示面板通过第一折线21或者第二折线22进行外折时,折叠后的柔性显示面板中还有相应的显示单元3正对着使用者,当柔性显示面板被折叠后,如果使用者想要使用显示功能,使用者依然可以通过与使用者正对着的显示单元3实现显示功能。但是如果柔性显示面板通过第一折线21或者第二折线22进行内折时,折叠后的柔性显示面板中并没有相应的显示单元3正对着使用者,使用者则无法使用柔性显示面板的显示功能,因此在本申请一实施例中,在柔性显示面板的非显示面上设置一个副屏,一个副屏与多个显示单元3中一个显示单元3对应,当柔性显示屏1通过第二折线22或者第一折线21内折后,整个柔性显示面板中仍然有一个副屏正对着使用者,使用者依然可以使用柔性显示面板的显示功能。
可选的,在柔性显示面板的非显示面上设置两个副屏,两个副屏与多个显示单元3中任意相邻的两个显示单元3一一对应,如图5所示。当柔性显 示屏1通过第二折线22内折后,整个柔性显示面板中仍然有两个副屏正对着使用者,使用者依然可以使用柔性显示面板的显示功能。当柔性显示面板通过第一折线21再一次进行内折后,整个柔性显示面板中仍然有一个副屏正对着使用者,使用者依然可以使用柔性显示面板的显示功能。
当柔性显示屏1沿着第一折线21以及第二折线22进行两次折叠后,位于第一折线21和第二折线22交叉处的柔性显示屏1容易发生褶皱,降低显示效果。因此在本申请一实施例中,柔性显示屏1的显示面上开设至少一个通孔4,通孔4与第一折线21与第二折线22的交叉点相对应,如图6所示。由于柔性显示屏1与第一折线21与第二折线22交叉处相对应的位置开设一个通孔4,因此当柔性显示屏1通过第一折线21以及第二折线22进行折叠时,避免了柔性显示屏1褶皱的产生,提高了显示效果。
可选的,多个显示单元3中相邻两个显示单元3上分别设置一个摄像装置,柔性显示面板具备摄像功能且在折叠过程中依然能够保持摄像功能。
可选的,柔性显示屏1包括:柔性支撑膜层11,叠加设置在柔性支撑膜层11的显示器件层12,依次叠加设置在所述显示器件层12远离柔性支撑膜层11的表面上的封装层13、偏光片14以及柔性盖板层15;以及,设置在柔性支撑膜层11、所述显示器件层12、所述封装层13、所述偏光片14以及柔性盖板层15中至少一组相邻两个层之间的粘结层16,如图7所示。本申请实施例中柔性显示屏1采用了柔性支撑膜层11以及柔性盖板层15,从而能够增加柔性显示屏1的柔性,能够实现柔性显示屏1的多次折叠。
在本申请一实施例中,柔性盖板层15为柔性透明聚酰亚胺薄膜或者超薄玻璃,聚酰亚胺薄膜以及超薄玻璃的柔性高,因此柔性显示屏1可以经过多次弯折,从而满足一个柔性显示屏1被弯折后被折线划分为多个显示单元3。
至于柔性显示屏1中相邻两个膜层是否需要粘结层16进行粘结,可以根据实际应用场景来进行选择,例如偏光片14与柔性盖板层15之间可以设 置一层粘结层16。因此,本申请对于柔性显示屏1中相邻两个膜层之间是否设置粘结层16不作限定。
可选的,偏光片14为通过粘结层16粘结在封装层13远离显示器件层12的表面上的超薄偏光片14,其中超薄偏光片14指的是:偏光片14的厚度不超过40μm,例如超薄偏光片14与粘结层16的厚度为66μm(其中粘结层16的厚度为21μm)或者超薄偏光片14与粘结层16的厚度为46μm(其中粘结层16的厚度为15微米)。
可选的,偏光片14为直接涂布在封装层13远离显示器件层12的表面上而形成的膜层,可以不通过粘结层16就可以将制备偏光片14,从而降低了柔性显示屏1的厚度,从降低了整个柔性显示面板的厚度。
可选的,柔性显示屏1进一步包括设置在封装层13与偏光片14之间的触控层17,如图8所示。通过触控层17的设置可以使得柔性显示屏1具有触控功能,丰富了用户的体验。
可选的,触控层17为通过粘结层16粘结在封装层13远离显示器件层12的表面上的柔性纳米银线薄膜,柔性纳米银线薄膜具有优异的柔性。无数根纳米银线在薄膜表面上形成类似刺绣的效果,且纳米银线之间的交叉点紧密,形成导电网络,实现触控功能。
可选的,触控层17为由金属材料沉积在封装层13远离显示器件层12的表面上而形成的具有网格状的导电金属层,金属材料为钛-铝-钛复合材料。由于触控层17是直接沉积在封装层13远离显示器件层12的表面上的,并没有经过粘结层16进行粘结,从而降低了柔性显示屏1的厚度,进而降低了整个柔性显示面板的厚度。可选的,当柔性显示屏1中其中一组相邻两个膜层之间设置一层粘结层16时,粘结层16的粘结材料为高恢复性光学透明粘接剂(以下简称OCA),即当柔性显示屏1经过折叠后再次展开的时候,粘结层16与水平线(水平线与折线垂直)之间的夹角不大于5°。由于粘结层16的材料为高恢复性OCA,能够使得柔性显示屏1在多次折叠后依然 能够很快恢复到平整状态。
OCA具有无色透明、光透过率在90%以上、粘接强度好、可在室温下固化且固化收缩小等特点。通过设置OCA粘接相邻两层膜层,可以在不影响柔性显示屏1的显示效果的情况下实现相邻两层覆盖层之间的稳固粘结。并且,当偏光片14与柔性盖板层15之间设置一层粘结层16时,粘结材料为高恢复性OCA,当柔性盖板受到外力冲击时,高恢复性OCA也可以吸收和释放部分外力,以降低外力对于柔性盖板的冲击,进一步提高柔性盖板的抗冲击性,进而提高了柔性显示屏的抗冲击性。
